RAP e4 - org.eclipse.rap.ui.forms [message #1728103]

I'm trying to run an e4 RAP application that includes some forms widgets in the package org.eclipse.ui.forms and below. These widgets are contained for rap in the org.eclipse.rap.ui.forms bundle.

In order to use them in an e4 RAP environment I have to include org.eclipse.rap.ui which I probably shouldn't. But anyway it mainly runs and renders the forms (ScrolledForm, Sections and so on).

The Hyperlink widget (org.eclipse.ui.forms.widgets.Hyperlink) does not work, though. If I include a Hyperlink I'm getting the following error:

Error: Error: Operation "create" on target "w279" of type "null" failed:
No Handler for type forms.widgets.Hyperlink
Properties: 
parent = w277
style = NONE
children = null
bounds = 5,29,46,20
tabIndex = 11
background = 0,0,0,0

Hi,
which RAP version are you using? Is the error reproducible with old
workbench based application?
Regards,
Ivan

Hi again,
just looked at the code in "org.eclipse.ui.forms". The JS code needed by
form widgets is specified in "org.eclipse.rap.ui.resources" extension
point. I doubt this will work in e4.
Regards,
Ivan

Do you know of a workaround? I could try to register these resources myself but don't know how.

Hi,
maybe looking into the old workbench RAP bundle will help. Anyway, you
will need to modify the org.eclipse.rap.ui.forms bundle i think.

Thanks, this helped. I just had to add the following two lines from the old WorkbenchApplicationConfiguration to my own app configuration's configure method:

        registerThemeableWidgets(application);
        registerResources(application);

(and I had to copy the code from WorkbenchApplicationConfiguration). With this, I can use the unchanged org.eclipse.rap.ui.forms bundle.
