Hi,

I tested the rap on e4 demo application and just noticed, that an exception is thrown, that prevents users from reloading the logindialog:

Problem
org.eclipse.e4.core.di.InjectionException: org.eclipse.rap.rwt.internal.lifecycle.UIThread$UIThreadTerminatedError

	... 11 more

Way to reproduce:
1. open the logindialog in browser
2. reload the site (infinite loading and exception)
3. on chrome it's not possible to access the logindialog again, without temporarily switching to a different website (or new tab), on FF its possible to chancel the reload and then reload and access the site again.

Do you have any ideas what causes this error and how to prevent it? Thanks for any help.

Someone from the core RAP team has to comment on what is going on there.
To me my code looked perfectly ok. I'm opening a shell and spin the
event loop until the shell gets disposed.

Could you please file a bug to the incubator - i need to someone from
the core-RAP team to find out what I'm doing wrong.

Hi,
In RAP UIThreadTerminatedError (ThreadDeath) *must* be propagated in
*any* case. I think the problem is that UIThreadTerminatedError is
wrapped in InjectionException (ContextInjectionFactory.invoke). We had
similar problem with equinox security [1] where the
UIThreadTerminatedError was wrapped in LogginException or
InvocationTargetException.

HTH,
Ivan
