[jira] Commented: (TAPESTRY-222) IE Error in DataPicker.js

Gary Orth commented on TAPESTRY-222:
------------------------------------

I had the same issue and it was the result of using absolute/relative positioning with DIV tags.  I resolved it by changing the while condition in DatePicker.js.

function getPoint(aTag)
{
   var oTmp = aTag;  
   var point = new Point(0,0);
  
   do 
   {
      point.x += oTmp.offsetLeft;
      point.y += oTmp.offsetTop;
      oTmp = oTmp.offsetParent;
   } 
   while (oTmp.tagName != "BODY" && oTmp.tagName != "HTML");

   return point;
}

> For some reason, the date picker throws an exception in IE in my app.  Works fine in Firefox.  I patched DatePicker.js by adding a try/catch block around the following code and it fixed the problem for me (and the calendar works).  Just FYI, I had to add this same patch to MyFaces popup calendar component too.

>           } while(aTag.tagName!="BODY");

>           // ignore
