I am working on IBM Rational HATS project and have the following environment.
Windows 7 Professional 64-bit Service Pack 1
IBM® Rational® Application Developer for WebSphere® Software 9.0.1
IBM® Rational® HATS 188.8.131.52
For the first time when I try to open any file from the HATS project it opens. Then I try to maximize/restore the view of the file editor by clicking on the file-name tab, it does work sometime but soon it fails and pops up this error attached in a Image2.jpg file. Then everything get disturbed on the perspective, all the views behave abnormally etc. It seems some serious bug in the product. I would like to have IBM representative shed some light on this problem. In the attached image error, I tried to open one style-sheet CSS file.
