- Summary:
Fix bugzilla bug 138176 Computed columns cannot rename

- Bugzilla Bug (s) Resolved:
Bugzilla bug 138176

- Description:
This bug is caused by the Model’s changes. Model has changed the “columnName” property into “name” and ComputedColumnHandle has left the setColumnName method empty. So the rename operation cannot take effect if we still use the “columnName” property. To fix this bug, we had to change “columnName” property with “name”.
