# 4556 Leaving the Collection Editor Open in the IDE Can Cause Incorrect Event Names

---

If you import a TDataset Columns then any where you have an event and you double click the event in the Object Inspector the event will have the name of the TDataset.

Example, I already have a TDataset called CustomerTbl, I add some new fields in EDBmgr then I drop the same table on my DataUnit and click Columns and export them to a file. I remove the new TDataset and click the existing CustomerTbl Columns and then click import from file. I now click on a TButtons event OnClick and the event will be called CustomerTblClick.
