Summary

Removing component and not Object error

Type             : Bug
Priority         : Low
Gambas version   : Master
Product          : Development Environment


Description
-----------

The scenario...

I have a From and using the project properties page i add the components gb.smtp.
Then in the IDE i add a smtp Network object to my Form.
If i go to project settings and select to remove the smtp and net components without first removing the Object from the form first the form fails to reload.
"Unknown Control SmtpClient"
Same thing happens with a TrayIcon
Not tested it it on others.

I have to open the project settings and re add the components, then delete the Object from the Form , 
, then Save the document (or it will force a reload), then i can safely remove the components.

If i Delete the object and then go to settings and remove the components without saving first the IDE says it has to Reload the form, if you select okay it puts the object back in and fails again.
If you select "Cancel" to the reload it's okay.
