Remote Assistance - Not always able to connect

I ran into a situation where I could not connect to my fathers PC using Remote Assistance. Now, given that he lives about 3000 miles away it is essential that I am able to connect with Remote Assistance to help him with miscellanious activities. I discovered that the Remote Assistance files are really nothing more than XML, and upon edting the XML I realized there was a series of invalid IPs in the UPLOADDATA block's RPTICKET attribute. Upon removing the invalid IPs I was able to immediately connect. I am not sure where they all came from (some were the obvious local IPs behind his firewall).

ExtJS ComboBox - Act like HTML Select

At first I struggled to get my ExtJS ComboBoxes to act like a straight HTML Select. In my application, I have a grid which loads the data into a store via AJAX. Later, create or edit dialogs display which contain a combobox of items represented by the store. Rather than load these again from the server, I wanted to reuse the data from the store. The problem I had is selecting a value in the dialog would filter the grid using the same filter. It appeared that ExtJS was applying the filter on the store rather than the view components. My original solution involved creating an array of items after the store had been loaded and passing this array to a combobox constructor. After further research, I was mistaken and the following needs to be done to make the ExtJS Combobox components would as a separate filter like an HTML Select:

1. Provide a hiddenId option to the ComboBox constructor.
2. Set the triggerAction to 'all'. Doing so essentially clears the filter and will treat the combobox like it is querying from the store separately.
3. Ensure the mode is set to 'local'.

Here is an example of a configuration:

   org.javad.CatalogueHelper = {

      getCatalogueSelection : function(id, options) {
         options = options || {}; // initialize if undefined
         var catalogues = new Ext.form.ComboBox(Ext.applyIf(options, {
         id: id, // Passed in id to create composite fields.
         fieldLabel: 'Catalogue',
         allowBlank : false,
         hiddenName: id + '-selected',
         name : id,
         mode:'local',
         editable: false,
         valueField: 'id',  // from store, what to store in FORM
         displayField: 'displayString', // Value to display in Select
         store: org.javad.CatalogueStore,
         hiddenId: id + '-value',
         width: 200,
         triggerAction: 'all', // key to clear filter
         selectOnFocus: true
      }));
      return catalogues;
      }
   };
