Hiding of all hideable columns not allowed?
I noticed that a user cannot hide all columns in a gridpanel. It seems that the grid must at least display one column. I can imagine this is a nice feature, but it doesn't work quite as I expected when dealing with both hideable and non-hideable columns. It seems that the rule is that at least one hideable column is required to display, even if there is a non-hideable column in the grid.
It doesn't make sense to me to not allow hiding of all hideable columns when at least one non-hideable column is displayed. Is this behaviour configurable?
I created a demo based on the Stateful Array Grid Example showing the problem:
