I've created a set of components that all had a set of properties that were standard throughout. So, I took these properties and made a component to hold these, and simply made the other components require a reference to this new component type.
EG. Components T1, T2 & T3 need a username and password.
I created Component T4 that holds a username and password.
T1, T2 & T3 now have a 4 property, requiring a T4.
I drop a T1 on the form, then drop a T4 on the form, assign the T4 to the 4 property of the T1.
Great! It all works fine, but I've found a problem.
If I delete the T4 component from the form, after assigning it to a T1, T2 or T3, I get error messages galore!
How can I handle this?
