| JDK-2164064 | OpenJDK6 | Sergey Groznyh | P3 | Open | Unresolved |
FULL PRODUCT VERSION :
java version "1.6.0_02"
Java(TM) SE Runtime Environment (build 1.6.0_02-b05)
Java HotSpot(TM) Client VM (build 1.6.0_02-b05, mixed mode, sharing)
ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]
A DESCRIPTION OF THE PROBLEM :
JEditorPane configured with HTMLEditorKit is often used as a simple visual HTML Editor. HTMLEditorKit.InsertHRAction is a an inner class implementing Swing's Action interface used to enter <HR> tag at a place of carret. As an example demonstrates it does not work anymore where it used to work before.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Examine the sample code. It creates a frame showing JTextPane filled with piece of HTML, then it clicks inside the text and invokes the InsertHR action. I have debugged the case and the InsertHR action is performed successfully, it seems to modify the element-structure of HTMLDocument. However no document-listener events are results this activity so the JTextPane's View structure is never updated so the displayed document does not visibly change.
Subsequent getText() method reveals there is no <HR> inserted to the document.
Would not it be better idea to deprecate whole HTMLDocument support and replace it with something better?
REPRODUCIBILITY :
This bug can be reproduced always.

Release Regression From : 5.0u12
The above release value was the last known release where this
bug was not reproducible. Since then there has been a regression.
