Df - ia

Edgar H. Pe�a C. — Wed, 05 Aug 2026 21:03:46 GMT

Hi all

We are looking for guidance on Document Processing (DF) versus AI.

For our ERP system, we want to read PDFs or images of documents (such as invoices), extract the data into JSON format, and automate the accounting coding. We could then handle the actual posting to the ledger internally based on that JSON data.

Any suggestions?

Toolbar in View

Tom Murphy — Wed, 05 Aug 2026 09:32:42 GMT

Hi

I want to put a toolbar inside a view.

But the find items don't work as the focus has moved to the toolbar item from form, before it checks if it's a DEO Object, has anyone got this working?

So the normal toolbar find items work, but the one's on the view's toolbar don't..

Better break-Line support for mixed environments

Samuel Pizarro — Tue, 04 Aug 2026 19:04:44 GMT

UserError method is vastly used in DD validations.

Legacy code, messages all have only "\n" as line-breaks.

But these get uggly, when such messages are shown in webapps. which only supports "\n\r" :-(

UserError is just one of them.

Data_Set_Error and other types of messages, like Error command, etc ...

we could have a uniform/consistent way to break-lines .

Today, you have to create compile directives and change all ocurrences to add the proper set of tokens accordingly.

Appreciate.

Navigate from Select to another select, when comming back, invoking object is not updated.

Samuel Pizarro — Fri, 31 Jul 2026 21:39:04 GMT

Select view A , with a non db-aware List. List is manually loaded.

The view has a main dd, for HEADER forms to select main record, that will be used to filter the list.

The header form has a navigation (prompt) configured to another selectview B, so the user can select the main record. and find the row at 1st view A. which will then trigger the list to be filled up.

so, it's a Select (A) -> Select B) navigation using ntFromMain navigation type.

The forward direction works just fine. But the Navigate back from "B" to "A" does not updates the record on "A" main DD.

I could verify the NavigateDAta has the proper sRowID and Tablenumber filled up with the correct row selected on "B" view.

Problem seems to lie on cWebView NavigateBackToHereExec private method.

It has a block logic to handle if the invoking view is a Zoom type, but it does nothing if its a Select type.

It assumes the mainDD for the Select is tied to the list, and assume the broadcast RefreshListForBackNavigation will handle it..
But in my case it won't, as on my Select "A" the main DD is not tied to any list, but in a form in the header.

And my main_Dd is never updated.

Makes sense ?

----------
Putting in WebOrder words..

Let's say you have a Select Order view, with a header forms to filter the order's list by customer.
And in that header form, you prompt to select customer.
After selecting the customer , and going back, the customer is never updated in the 1st Select Orders view.

I would expect this to work out of the box.. but it doesn't.

Can this please be reviewed ?

First detected it in DF 19.1 but checked the DF 25 source code is exactly the same, so I bet it would still happens there.

Thanks in advance

Has anyone made a Web Splitter type control?

Like the cSplitterContainer in windows.

Confirmation and Navigation Issue

Chris Spencer — Wed, 29 Jul 2026 22:00:20 GMT

I thought I'd mention something that caught me out today and
might be worth documenting.

I wanted to display a ShowYesNo confirmation before navigating to another view.
My callback simply did:

Code:

Procedure ConfirmCallback Integer eButton

    If (eButton = MBR_Yes) Begin

        Send NavigatePath

    End

End_Procedure



WebPublishProcedure ConfirmCallback

The callback fired correctly and NavigatePath was executed, however the destination view only partially rendered
(only the top portion of the view was displayed).

If I called NavigatePath directly from the original event (without ShowYesNo) everything worked as expected,
so it wasn't obvious that the message box callback was involved.

After a fair bit of debugging I eventually Found that the navigation needs
to be deferred into a separate server round-trip:

Code:



Procedure DoNavigate

    Send NavigatePath

End_Procedure



WebPublishProcedure DoNavigate



Procedure ConfirmCallback Integer eButton

    If (eButton = MBR_Yes) Begin

        Send CallBack (RefProc(DoNavigate))

    End

End_Procedure



WebPublishProcedure ConfirmCallback

Using CallBack resolved the problem immediately.

I eventually found an example of this pattern in the SetActionMode documentation,
but there was Nothing in the ShowYesNo or ShowMessageBox documentation that
suggested navigation should be handled this way.

Would it be worth adding a note to the ShowYesNo/ShowMessageBox
help stating that If the callback performs view navigation
(NavigatePath, NavigateForward etc.) it should be done via
CallBack so that it occurs in a separate server round-trip?

It would certainly have saved me a bit of Time,
as the symptoms looked much more like a layout
or navigation bug than a callback timing issue.

Navigate problem - view does not show if main record on target view is constrained out

Samuel Pizarro — Tue, 28 Jul 2026 18:36:59 GMT

First noticed in 19.1, but still happens on DF 25.

Navigation from Child , to select a parent record.

both views are DD bound, and invoking object as well

Like selecting a customer, when creating a new Order.

Lets say, you filter customer select to only show ACTIVE customers in this case, which makes sense. I don't want to allow an order to be created to an INACTIVE customer.

so, at customer-select you have this on customerdd

Code:

    Object oCustomerDataDictionary is a cCustomerDataDictionary

        Procedure OnConstrain

            Forward Send OnConstrain

            Constrain Customer.Status eq "Y"

        End_Procedure

        

    End_Object

Now, at the order view (child view) type 5 in the customer number, and click in the prompt button. to open the select view
Nothing happens, the view does not show. and no warning or error message is shown .

Now, leave the customer ID blank, or filled with a valid customer ID, the navigation works.

This is not ideal . I understand the fact the navigation is relational, and it's trying to get the current row and have it positioned at the target view. But it can't simply fail like that without any error or message,
Something is better than just doing nothing.

Ideally, we should be able to handle what should happen. if an error should be raised, or if we would allow the target view to have another row selected, the most nearest to the desired record.

Actually, this is what happens when you type a value that does not exist.. it opens the select in the neared value.

Type 200 in the order view (customer ID) and click in the prompt. the list comes with the last customer selected (id = 100) .

How to: Receive Complex Data back from Server to Client ?

Samuel Pizarro — Tue, 28 Jul 2026 00:56:59 GMT

Help teach us how the client can call a server function/event and pass complex data.

But the function only returns a simple datatype.

I need to send and receive complex data back . Similar to a byRef between client and server call , is that possible ?

The server would receive the complex data like described here.
Communication - DataFlex Documentation

But how can I send the modified complex-data back to the client, instead of just a simple value ?

Trying to find something in the help, and either analyzing the built-in js codes, but js is not my strength.. hard to find the pattern for me. ..

If possible, please daw, have a proper sample in the documentation would help a lot.

Appreciate any help

Regards
