ClearCase plugin still lacks UCM Integration. Ability of selecting an Activity before checkout (directly or as a result of some sort of refactor) is a must in our environment where we are building some applications on top of NB Platform using Maven.

After some mailing with NB support team we tried to implement the functionality in house.
It doesnt work well, can not check-out resource files like Bundles and form xml files all due to our insufficient knowledge about ClearCase/ClearQuest command line and source control API/SPI internals. Every refactor and checkout is really a pain.

Approach we followed was:

Checked out plugin sources and added a custom ClearCaseCommand to list "active activities" (activities that were marked as "Work On" in ClearQuest) from command line, parse the string response and display a dialog where user can select one. Then we set the selected activity as "default activity" of whole stream.

Besides letting us to keep development barely, this isnt really working well and as we dont have enough time and manpower.

As we dont have enough time and manpower to implement the functionality in acceptable way;

Is it possible that we share what we did and some people with some knowledge on IBM Rational tools and versioncontrol APIs may provide a better implementation (we are willing to contribute if guided) ?
