Help with property grid - Ext JS

I'm just getting started with yui-ext, and predictably I'm having an issue. I'm using alpha1 rev3, which has the spiffy new properties grid. The difficulty I'm having is changing the contents programmatically. I want to be able to have one set of properties and values and then replace it with another at my whim. This works fine unless I change one of the values in the grid. Then when I call myPg.setSource(mySrc) no change is visible, and I can no longer edit the values. Whenever I click on the grid I get the error "r has no properties" on ext-all.js line 216. What's weird is that it works if I click the header after each edit there's no problem, and if I have only one row then there is also no problem. Should I trigger a 'headerclick' message myself to simulate that click, or am I being some form of fool?

I'd start by upgrading to the latest release, alpha 3 rev 4.
