Name: ap153225 Date: 15/09/2004
FULL PRODUCT VERSION :
java version "1.5.0"
ADDITIONAL OS VERSION INFORMATION :
Generic
A DESCRIPTION OF THE PROBLEM :
Default caret's position in JEditorPane is 0
this is unacceptable for HTML documents, cause there is invisible <head> element in zero position
and in this case caret goes invisible too.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile and run the provided code,
and observe caret hiding
EXPECTED VERSUS ACTUAL BEHAVIOR :
The caret must be visible when JEditorPane is focused
ACTUAL -
After initialization and after setDocument() invocation for HTML documents
caret goes invisible
REPRODUCIBILITY :
This bug can be reproduced always.
