Custom source adapter UI

I am currently writing a custom source adapter that extracts data from a JD Edwards OneWorld system. In the custom user interface of the source component I need to allow the user to set a query (a custom property), and then refresh a list of output columns that will be extracted based upon that query (similar to the list shown in the advanced editor).

My question is, can I apply the custom property change to the component and build my output column list without closing and restarting my custom UI form? I understand that the IDTSComponentUI interface being implemented allows for transactional editing of the component, in that the changes to the component are not applied until I have returned a result in the implemented Edit() method. However is there a way to apply changes without returning this result (and closing my UI)?

Essentially I am looking to have similar behaviour to that of the 'Refresh' button in the advanced component editor form.

Thanks

The transactional edit work by cloning the component - the UI works only with the component clone, and can use all the functionality of the component. So when the component property changes, your UI should apply the changes to the clone, the component (clone) refreshes it output columns and then UI can show refreshed list of output columns. After user closes the UI, the changes are applied to the original component.|||

great, thanks for the response
