Hi there,

Our RCP product is updating from an eclipse 3.4 base to eclipse 3.6 and we are recommending that users reinstall rather than using the update mechanism.

Here is the situation in which I have a problem
1. I have a plugin installed which contributes a view, VIEW1, and i have that view shown in a perspective PERSP1. PERSP2 is my active perspective.
2. I reinstall eclipse (so I no longer have the plugin installed)
3. I start the new eclipse using the original workspace
4. I install the plugin again and restart eclipse as prompted
5. I switch to the perspective PERSP1 containing the view VIEW1
6. I receive this error:
"Unable to read workbench state. Reason: Problems occurred restoring perspective. Could not find view: VIEW1".

The problem seems to occur in step (4), when eclipse recognises that the view no longer exists and marks it as removed in the workbench.xml file.

The current workaround is to reset the perspective after receiving the error. Or by not allowing eclipse to restart at (4) you can kind of work around it. I think you would also be able to install the plugins headlessly without starting eclipse proper, although I haven't tried it.

The question is, why doesn't eclipse automatically detect at step (5) that the removed views have now been reinstated?

Thanks in advance,

Dave
