SAP bug

28 Views

Hi,

I'm experiencing a Nullpointerexception when I click on a button in my Web Dynpro app.

For testing purposes I'm throwing a RuntimeException in the button action handler,

but that RuntimeException is never thrown, so the problem is happening before the action handler is called.

When inspecting the stacktrace I would say this is a SAP-side bug.

Can somebody confirm this?

Thanks,

Jeroen
