After some debugging, I've found that when a zone update is initiated
all browsers call the 'onAction' function associated with the clicked
action or event link. However, only IE9 and IE10 proceed to call
'setupRender' and do a full page refresh, resetting the entire page.
This is why the null check fixed my earlier problem, but the issue is
still occurring in code that is more complicated. Any ideas on why
'setupRender' is being called each time an action/event link is clicked?

this invokes an AJAX request and, for some reason I have not found
yet, only IE9 and IE10 throw an exception.

error "Page must be specified before initializing for partial page
render"? My searches have come up nil and I'm curious what other
people have done to fix this.

Could you elaborate on this in regards to how this may cause the
exception to occur?

Are you sure that's what was happening - how is it IE-related?
If the zone to update is *inside* the page or component that has a
setupRender(), then setupRender() *will not be called* during
handling of
an Ajax event request (see
http://jumpstart.doublenegative.com.au/jumpstart/examples/ajax/whatiscalledandwhen
).
So I'd guess that either you have a component inside a zone declared
in the
parent page or component, or the request is not Ajax.

I figured out what was happening. I was using the 'setupRender'
method to
set the default value for the enumeration, like this:
void setupRender() {
_selectedBlockEnum = StoreFrontBlocks.HOME;
}
I didn't realize until now that this method is called after an
'onAction'
method, effectively overwriting the value set in the 'onAction' method.
Therefore I changed 'setupRender' to this:
void setupRender() {
if (_selectedBlockEnum == null) {
_selectedBlockEnum = StoreFrontBlocks.HOME;
}
}

Tapestry version 5.3.6
Hmm, it should have an up-to-date version. Have you checked the
browser
error console for JavaScript errors?

Hi!
Whch Tapestry version? Old ones use an old version of Prototype that
didn't support IE9 and IE10 yet. Your code and template look ok.

Greetings,
I'm having issues with the zone refresh from an AJAX request in
Internet Explorer 9 and 10 (it works fine in IE8, firefox, and
chrome). I
will click on the link and the new content will appear in the
zone for
about a half-second, then revert back to the original content.
Request.isXHR() is returning false, indicating that a non-AJAX
request is
occurring, which should not be the case. Is there a way to fix
what I have
or do these versions of Internet Explorer require a different
approach to
updating a zone and/or AJAX requests? I've included the relevant
tml and
java code below. Thanks in advance.
