[Paul_P]

Hello,

some of my colleagues are having problems with the CVS Client in MyEclipse Blue Edition. To reproduce the problem:
– right-click on a file in Package Explorer or Navigator
– click on “Compare with” -> “History”

A error window is shown, with the title “Problem Occured” and the message: An internal error occured during “Fetching CVS revision history”.
java.lang.NullPointerException

This problem doesn’t occur in Eclipse, only in MyEclipse (Blue).

Can you please fix this bug?

Thanks & Regards,

Paul P

Paul,
Is there any additional information about this error logged under <workspace>/.metadata/.log file?

[Paul_P]

Hi Nipun,

we get the following error in the log file (<workspace>/.metadata/.log). This error occurs in the perspective “CVS Repository Exploring” when right-clicking a file (no matter which one) from a project and then selecting “Show History”.

!ENTRY org.eclipse.core.jobs 4 2 2008-11-25 17:21:27.164

Paul,

I was unable to reproduce this using our Examples on Demand repository as an example. Can you go to the MyEclipse menu, then Examples on Demand, and install the DWRSpring application.

Then expand it, go down to summary.jspf and right-click, go to Compare With > History… and see what happens?

I attached screenshots of what I saw for comparison.

Aparna,
Can you try doing a reinstall and run from pulse? The following are the steps –
1. Download pulse from http://www.poweredbypulse.com.
2. Open pulse explorer and select “Eclipse Galileo” in the top left corner.
3. Your profile should be listed under MyProfiles. Slect it, right click on it and select “reinstall and run” from the context menu.
Let me know if this works for you.

[Aparna]

Hi Shalini,
I downloaded pulse but I don’t see my profile listed under ‘MyProfiles’ like you said. Please let me know what the next steps are in getting this to work, cannot do any merges because of this. Any help is greatly appreciated!

Thanks,
-Aparna

[support-shalini]

Aparna,
Can you clarify if you have selected “Eclipse Galileo” under realms? Can you send us a screen shot of your pulse explorer? You can use the PM button at the end of the post
to send the screen shot.
