Noob Beta 3 problem with dataprovider

Question

i have a component that loads data into a grid with an
HTTPService request. It works fine if i set it up as a separate
application with creationComplete="response.send()" defined in the
application. The data grid is populated as expected using:
<DataGrid id = "assignments" dataProvider =
"{response.lastResult.results.tasks.task}" >
<DataGridColumn ....etc.>
</DataGrid>
However, if i create the same logic as a component (with the
outermost container being a canvas) and place the same
creationComplete="response.call()" in the canvas, the display is
never updated when the component is loaded into another
application. I don't know if it matters or not but the component is
loaded into the application on a state change. The HTTPService call
gets made but the UI never updates. The only thing I can think of
is that its a timing issue. Any ideas? This is getting pretty
frustrating. :-(

Answer 1

The canvas in the component is rendered but the
creationComplete event never fires.
This is the component. I added the update_grid function so i
could put a breakpoint in it, rather than calling response.send()
directly . it never gets hit:
