Handling Compile Errors: K_DerefProp: objref arg is undefined (bad scriptText?)

[benloh]

1. Edit a blueprint.
2. Add a new line.
3. Add a prop keyword
4. Save to Server

You'll get an error on the prop keyword on both Main and the ScriptEditor:

If you look at prop.tsx, the error is probably because during compile the gemscript line is a partial line with just a keyword and no object ref.

I think this is a general question of how the system should handle compiles and errors of this nature.

1. if objref is undefined, do we just not compile? return an error state?
2. how should that error state be conveyed to the student?

We can discuss how to tackle.
