• um believe it or not there is actually a table_view_refresh.js in kitchen sink. how i've never noticed this file i'll never know. but anyway, after getting the reusable function rockin i just needed to create the tableview and add the tableview to the window outside the function.

  bam. success. thanks tamas and markus.

• is that data

  projTable.setData(data);
  

  declared somewhere else?, because is the data inside the xhr.open function, is not globally accessible.

• Hey Tamas, no data is not declared somewhere else. That seems to be my problem. I don't know how to make it accessible…data is populated by the xhr call response so it seems like I should be making another xhr call again at some point to get updated content…which is why I tried putting that into a function to make it reusable.

  Maybe setData is not the right solution here?

• there's an rss-example in KitchenSink with a reload-button. maybe you can use this as a good example how reloading works (even data is loaded from a rss-feed).
  if you want to move your requests into a function maybe this link (http://bradvernon.com/tag/titanium-mobile/) would be helpful.

• Thank Markus, exactly what i needed…filled in the gaps of my previous attempt at making a reusable function.

  And not to have every one do my homework ;) but now that i've my code reusable its grabbing the new content and appending it to the bottom of the existing list…not exactly refreshing or reloading…just adding to.

  Any ideas?

• anyway to mark my own answer as the best answer??

• also, a simple way to refresh an array is to simply do this: if your array is called data, just do data = []; and that empties the array.. then refill with new data and you are good.
