Hello All,

I have a problem with Descent0.53 + Eclipse3.3 + SuseEnt10(SP2). When I press CTRL+Space, I will see an error message:

----------------------------------------------------------------------------
The 'descent.ui.JavaNoTypeCompletionProposalComputer' proposal computer from the 'descent.ui' plug-in did not complete normally. The extension has thrown a runtime exception.

To avoid this message, disable the 'descent.ui' plug-in or disable the 'Other D Proposals' category on the content assist preference page.
----------------------------------------------------------------------------

There is no problem with Windows, but with SuseEnt10.
Is it possible to make it work again??

I've had problems with using Descent and newer versions of Eclipse. Descent will work on the latest version in the 3.2 branch.

Can you post the log? It's in your workspace under .metadata in a file called .log... Reproduce the error and then look to the bottom of the log; the stack trace of the exception should be there. Thanks.
