I hope that some of us meet this issue sometime. The Application I'm working on has GUI in SWT created.

Intrestingly, some of the Java Table function are working and some are not. E.g., I can select any cell of the table, but I can't select dig out the Cell Data using GetCellDate function.

Using this function, I get error message "The operation can not be performed"

Did any one have any Idea for this behaviour?
