Problem with showing popup message in Custom Install Handler [message #331017]

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

try:
Display.getCurrent().getActiveShell()
