I am noticing that my Lists height is not being calculated and the container resized accordingly after the list store is loaded. So, I have a list inside of a panel that is centered and packed for instance. The list loads but does not display the list because no height was explicitly given. I did try 100% and that did not work either. I noticed the elimination of doLayout. My question regarding List is, should the height be recalculating on the container after a list store load? or do I always have to give the list an explicit pixel height?
