Hi,

Environment:-

1. Richfaces 3.3
2. Internet Explorer 8
3. JSF 1.2

Scenario :-

I have multiple checkboxes and for each, i have assigned

<a4j:support/> tag for onchange event to reRender the component.

Behaviour :-

MOZILLA & IE9 :- As expected.

IE8 :-

I'm getting "Object doesn't support property or method 'fireEvent' "

from richfaces_impl_3.3.Final.jar

prototype.js file

{code}
 if (document.createEvent) {
        element.dispatchEvent(event);
      } else {
        element.fireEvent(event.eventType, event);  // error line
    }{code}

now due to above error

ajax for checkbox button is not working properly , ajax calls are happening but they are random , sometime they will work then if i click again it will not work .

ajaz calls are unpredictable , .....

FINDINGS:-

As per the network tab URL capturing of IE8

1. clicked on first checkbox - Nothing will happen. (Nothing displayed in URL capture)

2. clicked on second checkbox  , Ajax call happened.( Data came in tab showing ajax requests timing and server response). wait time : <1ms

3. clicked on second again nothing happened .

4. clicked on first again . this time ajax call happen , network tab shows the request information , wait time < 10.67 sec .

so my first click started the ajax request but was on wait and it got fired on the second click . WHY ??????

This behaviour is only with IE8 not in IE9 and FF.

How i can fix this issue ?????

I have seen this as a known issue .

Please provide the help .....Any ideas are also welcome.

any help will be greatly appreciated.....

Thanks
