IE6: NPE in JavaScript when using <t:calendarInput>
---------------------------------------------------
Key: MYFACES-870
URL: http://issues.apache.org/jira/browse/MYFACES-870
Project: MyFaces
Type: Bug
Versions: 1.1.1
Environment: Windows XP SP2
IE6
Reporter: Roland Huss
This Javascript error occurs in
do {
aTag = aTag.offsetParent;
leftpos += aTag.offsetLeft;
toppos += aTag.offsetTop;
} while(aTag.tagName!="BODY");
when offsetParent is null. This seems to occur on occasion in IE (e.g. within a
div with absolute positioning).
The same problem is described in TAPESTRY-173 and TAPESTRY-222.
A similar problems occurs at
while(objParent.tagName.toUpperCase() != "BODY" ){
objLeft += objParent.offsetLeft;
objTop += objParent.offsetTop;
objParent = objParent.offsetParent;
}
Again, offsetParent can be null in IE6. An additional condition in the while
loop prevents this gotcha.
These problems doesn't occur on firefox 1.0.x
My temporary solution is to catch the NPE and simply ignore it.
