Empty rows when dynamically changing Store and Grid columns
Hi,
I am trying to dynamically changes the contents of my grid by reloading the store and recreating the columns in the grid. I'm almost there, but for one of the views, the grid columns change correctly, but the rows aren't loading. I included a simplified scenario to demonstrate. Any ideas? Thanks in advance.
