Getting error "mCols: Cannot perform this operation on a closed dataset" when going to triggers tab under certain circumstances.
Steps to reproduce the problem:
Login to a database and:
1. Open schema browser
2. Create table (name and columns aren't important)
3. Click on the table name in the left part of schema browser
4. Open "data" tab in right part of schema browser
5. Click "drop selected table" on left part of schema browser and drop table
6. Click "triggers" tab on right part of schema browser
7. Click "Data" tab on right part of schema browser - error appearing "mCols: Cannot perform this operation on a closed dataset.
WORKAROUND
This only happens when trying to see the triggers and then the data of the deleted table.That is a refreshing problem.
To see the triggers for any other table just select another table on the Schema Browser and then go to see the triggers or the data tab.
STATUS
Waiting for fix in a future release of Toad for Oracle.
