add views dynamically when using the compat layer [message #1602092]

Hi,

I am currently trying to get my 3.7 application to run in rcp 4.4 via the compat layer. The application launches but I use views which are added via extensions. This leads to a NullPointerException when calling

pageLayout.getViewLayout(id).setMoveable(isMoveable);

in my Perspective, since

folderLayout.addView(id)

is not able to create a view model via

ModeledPageLayout.createViewModel(..)

because the id does not match any existing partDescriptor's id.

Is there a way to add the view at runtime?
I do not have access to the EPartService, MApplication,... since my class is not known to the application model.
Did I misunderstand something when assuming that the compat layer runs 3.x applications without any major changes?

thanks for your help in advance!

some clarification:
The views I use are actually added to the extension point org.eclipse.ui.views at runtime. This means that only the currently shown dashlets are registered. Registering those views still works in with rcp 4.4 but the application model does not seem to get updated and therefore knows nothing of them.
As soon as I add views statically to the extension point, the view is known to the application model as part descriptor (my guess is that the compat layer parses the plugin.xml during startup and then never again).

This changes my question to: Can I trigger an update of the compatibility layer's application model at runtime to update the known partDescriptors based on extensions?

I to am attempting to migrate a 3.7 application to 4.4. We are currently using the internal API to accomplish creating dynamic views and other things. I was reading up about the process used to complete the migration. My understanding is that the comparability layer will not work if we are using internal API classes.

A big part of what we do currently depends on the ability to create views and such dynamically. So any insight on making dynamic views either using just the 4.4 API or converting 3.7 stuff using internal classes would be greatly appreciated.
