Same issue with 0.9.4 version
0.9.3 works fine

I get the same issue with 0.9.5 if I change to the cells view immediately. If I wait for 10 min or so after starting cf top, I can switch to cell stats without any issues.

Same here with 0.9.5 (and CF CLI version 7.4.0+e55633fed.2021-11-15).
But thanks to the previous comment, I finally could open the cells view after waiting for all meta data to be loaded as a workaround.

[mauricebrinkmann]

stackGroupMd := asUI.GetMdGlobalMgr().GetStackMdManager().FindStackGroupByStackGuid(appMetadata.StackGuid) if displayCellStat.StackGroupId == "" && appMetadata.StackGuid != "" { displayCellStat.StackGroupId = stackGroupMd.Guid } if displayCellStat.StackGroupName == "" && stackGroupMd.Name != "" {
The last line is the failing cellListView.go line 166 and there is a check for displayCellStat != nil before, so the same check is missing for stackGroupMd or how should be the logic if that is nil or not containing a valid Name field?
