actionFunction works in IE but not Firefox?

Given the same VF page and Apex controller using a very simple example invoking the actionFunction, I am seeing that it works only in IE and not in Firefox.


The controller code:

public class TestAction {

public String ExposeID { get; set; }

public PageReference toggleItem()
{
ExposeID = Apexpages.currentPage().getParameters().get('firstParam');
system.debug('~~~~~~~~~ IN TOGGLE ITEM');

return null;
}


}

The page code:

<apex:page controller="TestAction" tabStyle="Account" sidebar="false">
<apex:form >

<a href="/apex/TestActionPage?expose=12" onclick="toggleItemJS('12');">Item 12</a>

<apex:actionFunction action="{!toggleItem}" name="toggleItemJS" rerender="showstate" >
<apex:param name="firstParam" assignTo="{!ExposeID}" value="" />
</apex:actionFunction>

<p><apex:outputText value="Item Exposed: {!ExposeID}" id="showstate" /></p>
</apex:form>

</apex:page>



When using IE as the client browser, the debug window shows:

As you can see, it called the toggleItem function correctly.

But when I use a Firefox browser (tried 2.0 , 3.0 and 3.5), it only writes:

10:04:50 DEBUG - ***Begining Page Log for /apex/TestActionPage Cumulative profiling information: No profiling information for SOQL operations. No profiling information for SOSL operations. No profiling information for DML operations. No profiling information for method invocations. ***Ending Page Log for /apex/TestActionPage?expose=12

It did not invoke the toggleItem function at all.

Does anyone know what could be the problem?

thanks,
Pi

Turns out I was watching the System Log window's Apex Code Debug printouts as the code executed.  The debug logs under Monitoring do print out the method invocation when using Firefox, so this looks like a bug in the System Log dialog windows for Firefox, or there are additional steps to get the full stack printed in the System Log window when using Firefox.

I would try using a commandLink tag instead of the regular href tag ...
