Icons not showing in GridPanel Command Columns
I'm running into an issue with icons failing to display in GridPanel columns such as CommandColumns.
If I apply an icon (such as the "Lorry" icon) to the panel itself, that icon works....if I apply other icons to the columns, they do not appear. If, however, I apply an icon to a column that's already loading on a panel header elsewhere on the page, then those column icons appear correctly.
It looks like somehow during rendering the column icons are getting lost when the GridPanel renders unless the icon was already rendered at some point in a parent panel.
