Hello!
I'm still having some trouble with my test-application and IE.
The intended functionality is the following:
Page consists out of three PropertySelections, one TextField and one
Checkbox.
PropertySelection 1 affects the content of PropertySelection 2 and
possibly the content of PropertySelection 3
PropertySelection 2 affects the content of PropertySelection 3
PropertySeleciton 3 affects both TextField and Checkbox.
Using Firefox, the components get updated as they should.
However, using IE doesn't work. The EventListener gets called on the
first change of Selection 1, but the other Components don't get updated.
If i change the value of that Selection again, the application crashes
before the EventListener is called. Additionally the (should be)
affected PropertySelections don't get updated during the run of the
EventListener. If there was a working Selection before in one of the
affected Selections, these are gone after the first EventListener-call
as well.
I'm using last nights svn-snapshot of Tapestry for testing.
Did i miss something or is there really a problem with Tapestry411/AJAX
and IE?

----------- Test Page -----------------
The html-template looks like this:

<div jwcid="[EMAIL PROTECTED]" id="button"

</form>
<form jwcid="[EMAIL PROTECTED]" async="ognl:true"
