FULL PRODUCT VERSION :
java version "1.5.0_09"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_09-b03)
Java HotSpot(TM) Client VM (build 1.5.0_09-b03, mixed mode, sharing)
ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]
A DESCRIPTION OF THE PROBLEM :
JTextPane having HTMLEditorKit works fine when a new document is opened. However if an already saved document is opened and right/left/center alignment attributes are added we do not get the changed document with JtextPane.getText method. UI does show that text is aligned as per the action but getText returns the old document. If we open a new document it works fine.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Execute this programm below:
2. In the text pane type "Hello" on first line and "there" on second line
3. right align the second line
4. save the content to a file
5. exit the programm
6. again launch the programm and open the saved file.
7. You will notice that contents are correct
8. now center align the second line
9. save the file
10. You will notice that content is not saved however UI does show that alignment is applied. This can be seen on console as well when you click "SaveFile" button.
Some time it happens the other way round, UI does not show the change but getText returns correct text with proper alignment.
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
this behaviour is not expected
ACTUAL -
when content is saved to a file using getText and then same content is opened in TextPane and edited we should be able to set the alignment.
REPRODUCIBILITY :
This bug can be reproduced always.
