Hi,
maybe there is some gc problem with closures in IE9 document mode.
Simple test page leaks memory in IE9 mode even if first suspect
Wicket.replaceOuterHtmlIE
is commented out. Test with plain XMLHttpRequest does not leak memory in any
case.
This Wicket Ajax example also slowly grows if IE9 document mode is set manually
but is not
seemingly leaking in IE8 mode

Hi,
Can you share your findings ?
What exactly you think caused the memory leak and how exactly did you solve it
with jQuery ?
