Question

I want to be able to change how an ExtJS Component formats the POST data.

To be more specific I am using the MultiSelect user extension. The post data is formatted with a single param with comma separated values.

i.e. multiSelect = 1,2,3

The way in which I need to handle this is to have multiple identical attributes

i.e. multiSelect=1 multiSelect=2 multiSelect=3

The MutliSelect component is the following

var multiselect = new Ext.ux.Multiselect({
    name              :  'multiselect',
    fieldLabel        :  'Multiselect',
    dataFields        :  ['code', 'desc'], 
    data              :  [['1', 'One'], ['2', 'Two'], ['3', 'Three'], ['4','Four'], ['5', 'Five']],
    valueField        :  'code',
    displayField      :  'desc',
    width             :  150,
    height            :  150,
    allowBlank        :  true
});

Not 100% that this will work, but I suspect doing something like this should:

Ext.override(Ext.ux.Multiselect, {
  getValue: function() {
    var returnArray = [],
      selectionsArray = this.view.getSelectedIndexes(),
      i;
    for (i = 0; i < selectionsArray.length; i++) {
     returnArray.push(this.store.getAt(selectionsArray[i]).get(((valueField != null)? valueField : this.valueField)));
    }
    return returnArray;
  }
});

Sending an array should get it to use normal Ext.urlEncode behaviour.
