action_params

[GoogleCodeExporter]

action_params does not sends the refreshed value to the server. It sends the 
initial values when form is loaded initially.

I am pasting my code as below:

I have a select box, I change some value in multiselect and then I try to
upload file and pass changed value of multiselect to servlet in
"action_params" but in servlet I don't get the changed value instead get
the value when form was iniitally loaded. For example initially when form
was loaded default value for select was "RNL", now I change that to "SAB"
and send that value to servlet while uploading a image, in servlet I get
"RNL" instead of "SAB"

<SELECT id="category" name="category" onchange="selectTestFun();">
<OPTION  value="RNL">Restaurants & Night Life</OPTION>
<OPTION  value="SAB">Spa & Beauty</OPTION>
<OPTION  value="AAE">Activities & Entertainment</OPTION>
<OPTION  value="SHAB">Shopping & Boutiques</OPTION>
<OPTION  value="HAT">Hotel & Travel</OPTION>
</SELECT>
 <input type="button" id="uploader" value="Upload">
<script type="text/javascript">
upclick(
    {
    element:document.getElementById('uploader'),
    action: '/WonderAdmin/UploadImage',
                                    action_params: {'category':
$("#category").val()},
    onstart:
      function(filename)
      {
     var fileSub = filename.substring(filename.lastIndexOf("\\")+1);
        alert('Starting upload: '+fileSub);
        $("#hiddenFileName").val(fileSub);

      },
    oncomplete:
      function(response_data)
      {
        alert('Uploaded!');
        alert(response_data);
        $("#hiddenFileId").val(response_data);
      }
    }
);
</script>

Thanks and Regards,

I fixed it by reseting values on the oncomplete event using prototype:

        upclick({

            oncomplete:
                function(sResponse)
                {
                            // ie8 workaround not resetting action_params
                            var cFixIe8 = function (sFoobar) {
                                var aInputHidden = $$('input[name=sFoobar]');
                                for (var i = 0; i < aInputHidden.length; i++) {
                                    if (aInputHidden[i].getAttribute('value') == null) {
                                        aInputHidden[i].setAttribute('value', sFoobar);

                                    }
                                }
                            };
                            cFixIe8.delay(.1, sFoobar);

                }
        });

All right.

Action_params parameter is initialized once.
Particularly, action_params: {'category': $("#category").val()} works once. 
During initialization.

The decision ...
Simple solutions do not see.

In the future, perhaps, add callback-functions support as the value 
action_params.

Thanks for the issue.

Fixed;
* action_params reset and set again when file upload twice

* action_params may be callback function, who return object
  action_params: function() {return {'category': $("#category").val()} },
