Description

Hi, I would like to report an issue with column pinning. It looks like sometimes (I can't reproduce the issue whenever i want) the pinned column becomes all white (until I scroll the grid, then all the values come out) and if I try to resize this column it gives me the error Cannot read property 'colDef' of undefined at ui.grid.min.js:12 (I couldn't find where the error is with the unminified version)

I had to unpin and then pin the column again to make it work. I'm sorry I can't provide you more details, but I hope this report can still help you.

Research direction
The issue is an intermittent bug with pinned columns where the column turns white and resizing causes 'Cannot read property 'colDef' of undefined'. Investigate the column resize logic in ui grid, particularly the handling of pinned columns. Look for conditions where the column's colDef becomes undefined. Review the code in ui grid.js around column resizing and pinning.
