Dojo accordion container programatically display grid when collapsed
I started learning Dojo yesterday, so please excuse my ignorance...
My expectation is to create an accordion dynamically and show a grid in the content pane of the accordion. To do that I create the accordion widget with 2 content panes and when the content pane is onShow handled, I create a custom widget and add to the content pane (this is a necessity, i.e., I cannot add a data grid directly). Once the custom grid is created it creates a timer and on the timer's elapse I populate the grid and show it.
Now, if you run this in a browser (of course with dojo in the right path), you would notice after about 8 seconds timeout, the accordion pane shows the grid (in a clumsy way, which I still need to figure why, any help would be great). But then:
If I open the second pane immediately (well within 8 seconds) after refresh and keep first pane closed until after 8 seconds and then open the first pane, nothing seems to be present. Could Dojo experts kindly help me understand why? Thanks!
