JSCookmenu browser leak
-----------------------
Key: MYFACES-309
URL: http://issues.apache.org/jira/browse/MYFACES-309
Project: MyFaces
Type: Bug
Environment: myfaces 1.0.9
Reporter: Werner Punz
Hi I know I am picky....
But has anyone checked the more dynamic components for mem leaks.
After having spent several hours yesterday to remove some of those dreaded
leaks in my ajax component on sourceforge.
I ran the test against the jscookmenu today and got the painful result of
several component leaks.
The problem in those cases is not how that the javascripts are incorrect but
that the browsers basically cause so called component leaks once you have a
cyclic reference between a global javascript object and one from the dom tree.
(at least the IE does dunno about the Moz)
The problem unfortunately is well known and called mem leak bug and since a few
days there is a good tool at least on windows to detect them, which is called
drip .

Given my experiences from yesterday, debugging my own stuff, I can say, that I
trust the results from drip regarding leaked components, they resemble my
experiences and errors I did myself.
It is not a big bug, but given that some webapps probably use the jscookmenu
for hours, it is nasty enough, to be fixed in the long run.
The problem with the mem leak bug is, that a page change does not recycle the
leaked objects only a closing of the browser does.
