[equinox-dev] Re: [p2-dev] Problem with showing popup message in Custom

This question should be asked on the platform newsgroup. I think the problem comes from the fact that you are trying to open the window from the wrong thread.

Subject:	[p2-dev] Problem with showing popup message in Custom Install Handler

---

Hello All,
 
   I am using Eclipse 3.3 for plug-in development. We have used Custom Install Handler to customize plug-in installation for our requirement. We wrote a InstallHandler with extending BaseInstallHandler class and override completeInstall() and completeUninstall() methods. But we want to display popup message to user during feature un-installation. 
 
I have tried with MessageDialog.openInformation() in completeUninstall() method but it throws NullPointerException while executing getSystemImage() method of SWT class.
I have also tried with ErrorDialong.openError()in completeUninstall() method but it throws SWTException:Invalid Thread Access
When tried with PopupDialog it requires parent shell that is not there in InstallHandler code.
 
Please provide your valuable suggestion for implementation strategy.
 
Thanks & Regards,
-Hardik
