Amending the TestPageGenerator xslt file

StephenElliott — Fri, 08 May 2026 14:30:31 GMT

Hi Everyone,

Just a quick query if anyone has any advice.

I'm thinking about amending the .xslt file for the TestPageGenerator in the .wso ini file to add a little bit more instruction about how to consume a published function. Common queries that we get etc... It would also help new developers here (and me remembering after not having looked at it for months).

Where is the best place to put the new .xslt file? I don't want to have to remember to update the file after every server install.

I tried putting it in the AppHTML folder and that works, but are there best practices for this kind of thing?

Thanks for any input

SetActionMode catch involving ShowYesNo

Nicholas Herlick — Thu, 07 May 2026 23:02:55 GMT

I've got a button that starts a report. If a gift "Billing Code" is not "P" it opens a ShowYesNo to ask for confirmation to "Continue" anyway. Because "SetActionMode" is in OnLoad its (RefProc(OnClick)) would be the normal argument. But when the YesNo question gets involved a Yes response calls RunTheReport from BillingCodeCallback not OnClick. How can The scModeProgress be invoked whether or not Billing Code is "P"? FYI - I am not trying to use both versions of "Send SetActionMode" - I included both just to show the choices and dilemma. Is there a way to use (RefProc())? I don't want the progress display to ever be just an hourglass.

Code:

        Object oStartReportBtn is a MWcWebButtonStartRpt

            Set piColumnIndex to 0

            Set piColumnSpan to 5

            Set psCaption to "Start Report"

            Set pbServerOnClick to True





            Procedure BillingCodeCallback Integer eConfirmMode

                If (eConfirmMode=cmYes) Send RunTheReport

                Procedure_Return

            End_Procedure

            WebPublishProcedure BillingCodeCallback





            Procedure OnLoad

                Forward Send OnLoad

                // uses new global string in MWGlobal.pkg

                Send SetActionMode (RefProc(OnClick)) scModeProgress gsAuditProgressPleaseWait 

                Send SetActionMode (RefProc(BillingCodeCallback)) scModeProgress gsAuditProgressPleaseWait 

            End_Procedure

        

        

            Procedure OnClick

                String sBillingCode

                

                Send Request_Save of RptSetup_DD

                WebGet psValue of oBillingCode to sBillingCode

                If (sBillingCode <>"P") Begin

                    Send ShowYesNo (Self) (RefProc(BillingCodeCallback)) 'Billing Code "P" is standard for Payroll Plans. Continue?' gsPleaseNote

                End

                Else Send RunTheReport

            End_Procedure

        End_Object

Best, Nick

Problem with Safari

Mike Cooper — Tue, 05 May 2026 20:56:08 GMT

Today we found that users with Safari as a browser have an issue saving fields with a mask.

Specifically this mask in a cWebForm

Code:

Set psMask to "(###)###-#### ******"

The problem is, I develop in Windows and can't find an easy way to troubleshoot this issue.

I see you can install Safari for Windows, but the last version is about 13 years old and likely full of vulnerabilities.

Any thoughts on how to test this in a development environment?

My best guess so far is to use a separate Mac computer to test on a development website, but this puts a step in between developing and debugging.

Open a view in webapp with no logon

Chris Spencer — Tue, 05 May 2026 06:24:43 GMT

Hi,
I have circled back to this.

Trying to open a public View

No login required
No dashboard/menu
Simple flow (entry → action → done)

Docs suggest using:

pbLoginModeEnforced=False
deep link (Index.html#oView)

But in practice:

Still gets redirected to login
#oDashboard/oView clearly hits login first
#oView doesn�t consistently work either
Interaction with AllowAccess / AllowViewAccess unclear

Question

What is the correct, supported pattern for opening a view directly from a URL without login?
A working end-to-end example would help � multiple people seem to be hitting this.

pbPassword in a cWebForm

Allow user to verify email address

Chris Spencer — Sun, 03 May 2026 23:28:12 GMT

In a DataFlex WebApp, I need to implement an email verification link such as:

https://example.com/MyWebApp/VerifyEmail?token=xxxxx

The user will not be logged in. The token itself is the proof.
What is the best way to create a public unauthenticated endpoint that can:

read a query-string token,
validate it server-side,
update a SQL table,
then show a simple success/failure message?

Is this best done as a WebView with login disabled, a custom WebService/object, or some other handler pattern?

Is there anything published on this ?

soap "Unexpected parameter"

Sjoerd — Wed, 29 Apr 2026 13:45:17 GMT

An external program pushes an soap to our server with an WSDL file they have provided. However in their WSDL the can leave out some fields an that is something that DF doens't like. Is there a workaround for it? Or is it possible to retrieve the complete soapenv?

I've loaded the WSDL with DF24.0, no problems there.

DF 18.2 WebApplication - Cant get it to work locally

MrHalland — Wed, 29 Apr 2026 07:42:58 GMT

I needed to fix an old version of a WebApp in DF 18.2 (Don't ask why :) ) Running on Windows 11

I registered the application thru the Studio (in project properties).

It added the application to the web app administrator and into the IIS

When i try to start the application i get the folowing error.

Konfiguration error, can't read configuration file due to insufficent rights (translated freely from swedish)
Error: 0x800700005

So the web.config is missing even tho i compiled the app, all other files are created under AppHtml, *.wso files.

Is there some thing missing after the installation of DF 18.2. I have other applications in 20, 23 and 25 running so the ASP ISAP backwards compability is installed as required.

I don't know where to look.

At the customers site there is no web.config and there the application runs.

Any hints suggestions?

web.config when compiling

MrHalland — Wed, 29 Apr 2026 07:38:08 GMT

Hi!

When compiling the web.config is updated, how ever for some reason it does being built in error.

The section with the webservicedispatcher is being written incorrectly

the dataflexhttpmodule is not written inside a tag but outside.

It doesn't matter if i delete the file, it keeps doing that.

This is in the latest version of df 25.

MAC address from Tablet/Phone/whatever

DaveR — Tue, 28 Apr 2026 14:31:13 GMT

Just thinking something through, but if we release an app we are working on as a webapp it will mostly be accessed by mobile devices. I recall the MAC address code posted in here (something like 20 years ago!) worked at the time but we replaced that (PC) identification method with others.
Before I put any resources into modeling this, is anybody registering phones/whatever for webapps by their 'wifi address' or 'bluetooth address' which both appear to be MACs?

Error: 4402 on WebGrid and DD constraints

Chris_V — Fri, 24 Apr 2026 04:35:11 GMT

Hi All,

DF 20.1, ODBC, PostgreSQL.

I have a very simple DD parent-child structure (PTARE.PTARE_SYS_KEY <> PRODUCT.PTARE_SYS_KEY ) which I want to change constraints on the child DD to change data displayed in a webgrid.

Both DDs have the same simple constraint to a non-related table field, TENANT.ID.

Even though they have same constraint to the same TENANT.ID record I set the PRODUCT DD to "Set pbInheritConstraints to False" so the parent's PTARE constraint are ingnored.

On the Web View I have three radio buttons above a WebGrid. Each radio button's OnSelect procedure set a property in the PRODUCT_DD and sends Rebuild_Constraints to the same object and then send RefreshListFromDD to the WebGrid to re-display the DD's newly contrained records.

This appears to work fine when I click on the different radio buttons, until I enter the WebGrid and navigate up or down a row where upon I get the "Unhandled Program Error" dialog displaying "Assert: Server DD's current record does not match psCurrentRowId", Error: 4402, Line: 28548 (which inside the pre-compiled DF packages).
PRODUCT_FAST_INACTIVE_ROWID_ERROR.jpg

This only seems to occur when I go from one exclusive set of constrained records to another that the first record does not appear.

I tried to clear the DD after each radio button constraint change without affect.

Using the "Web DD Debug Inspector" in my code it appears the Rebuild_Constraints isn't always being applied.
For example in this screenshot the "Product Inactive Fast Entry" Webview's grid filter radio button "Only Inactive" is selected (red box), but the constrain value is blank for the "Only Active" radio button constraints (green boxes) and th RowID field is empty (red oval).
So the PRODUCT_DD's constraints seem to get out of alignment according the Web DD Debug Explorer screen shown here.

Any help would be appreciated.

Here's my code.

Code:

// Inactive Product Fast Entry

Subclass js question/confusion

JeffKimmel — Tue, 21 Apr 2026 16:19:40 GMT

All,

I'm working in subclassing some web objects & I'm slightly confused (OK a lot) on something. I have this defined in my JS subclass:

afterRender : function(aHtml)
{
RF_WebFloatingPanel.base.afterRender.call(this, aHtml);
df.dom.on("mouseleave", this._eElem, this.onMouseOut, this);
df.dom.on("mouseover", this._eElem, this.onMouseOver, this);
},

onMouseOut : function(oEvent)
{
console.log("onMouseOut 1 ");
//this.fire("OnMouseLeave"); //Why does this not work!!!
this.serverAction("OnMouseLeave", [ ], null, function(oEvent)
{
if(oEvent.sReturnValue === "1")
{
}
}, this);
console.log("onMouseOut 2 ");
},

Using the 'serverAction' works but 'this.fire' does not and I'm not clear as to why. althouhg I'm assuiming the 'this' in the instance isn't what I want or need. 'this.fire' doesn't do anythign, it doesn't even popup an error. I'm guessing I'm missing some step somewhere but I don't see what it is. The code above works so that may just be how I need to do it but I'm a little concerned this is not the right way to do this. Any help is greatly appreciated.

Thanks,

Jeff

Use Class for view and dialog

Alspaugh — Thu, 16 Apr 2026 16:02:40 GMT

I am using DataFlex 2024 and moving my Windows application to WebApp. I want to have a screen that can be Launched as a view or a modal Dialog. Which I understand can not be the same screen. I build a class to use that has most of the screen and it works. However, when I use the class, it doesn�t appear in the WebApp designer which makes it hard to make adjustment.

One suggestion is to build the screen in the view and then cut and paste into the class. If I am going to do that, I might as well just cut and paste into the dialog.

Is using a class the proper way of handling this, if so when add to a view or dialog can I make it viewable in the designer? Is there a better way of doing this?
