Problem description: Thai word wrap does not work properly in Label text

Steps to create the problem
1) Create a label in the logic editor by dragging a label from the palette.
2) Click on the label's text and then enter long Thai text into the label until the line wrap occurs. 

Please note that Thai word break works correctly while editing Thai text in label.

3) Click mouse outside the label to quit from edit mode.

Problem: After exit from edit mode, Thai word break does not work correctly on label text (Please see the screen captures in the attachment).

Please investigate the problem.

Thanks, Suwit

Can you retry this with the M6 stack?  GEF M6 migrated to the ICU4J plug-ins in M6 and specifically their BreakIterator implementation which is supposed to be more "intelligent" then the default Java implementation.  BreakIterator is what determines where to make the appropriate word-wrap break point.

I've tried Eclipse 3.2 M6 I20060331-2000 and GEF 3.2 M6 I20060405
Unfortunately the problem still persist.

It seems that text display in label may not use BreakIterator class to determine the break position. In the other hand, Thai word break works correctly in edit mode (Right click on label and select Rename from popup menu)

If you need more information, please let me know.

Thanks, Suwit
