Toolset - Drag and Drop of a DataType to the FB with validation error changes the values of namespace, name and version of the functionblock to null

[deepagithub]

Steps:

1. Create a datatype e.g.

entity TightenResult {
	  optional cellId as int
	  optional channelId as int 
}

2. Create a function block e.g.

functionblock Magnetometer {
	operations {
                getval() returns TightenResult
	}
}

3. The function block has a validation error that the referenced model has to be imported
4. Drag and Drop the entity to the function block

Expected Result:
The datatype should be included in the function block. The function block should have a statement "using.." referencing the data type.

Actual Result:
The Functionblock's namespace, name and version becomes null.
This is related to #622

I can't reproduce this on Neon.2, Neon.3 and the latest Oxygen R with the latest nightly build

I've been able to reproduce this, but only when the return type is fully qualified, not when it's just the 'name'. Anyhow, there are workarounds for this so I think this is not that critical.
