Description
With OFBIZ-7029 I replaced some widget list forms by grids. I don't know why yet but there are some cases, like at webtools/control/FindUtilCache, where it crashes.
I mean I know why, but I don't know why yet it's not in all places. For instance accounting/control/ListFixedAssets has not this problem.
I'll fix the current issue and later check what is the difference between both cases (maybe another Jira issue)
