Mike,
I wanted to use the {Webproperty=Server} in my webapplication migrated from 18.1 to 19.0.
I receive the error message
It occurs on the Webset and not on the WebgetCode:Unable to Webget/WebSet the server property. The ghoWebappServerPropStore is not initialized. The most likely cause is the WebAppServerProp table not being available. Erreur Dataflex N°:4402
It's solved now. I had to add the object containing the Web property. I didn't know that the Webset didn't delegate.
