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,

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