After running analyze for the first time, login window appears in eclipse web view.
Login with login credentials.
After login dashboard appears properly.
Now right click on project which is configured with sonar eclipse plugin for analysis.
Now do not do anything. Just come back to web view in eclipse.
Now there is no dashboard. Just three tabs with no data. Violation tab just shows violation numbers. No other data.
I think there is no issue with built in browser in eclipse. As when i choose project right click -> sonar -> open in sonar server: I can see sonar dashboard properly. Screenshots for each steps can be found in the attachment.
