DNU: receiver of "allAttributes" is nil

Hi!

I am building a small meta-models for c++ analysis.

I have created a class called PCPPFunction, a subclass of MooseEntity. (I know there is a FAMIXFunction, but the PCPPFunction is radically different from FAMIXFunction because if contains many information about dynamic analysis).

When I visualize instance of PCPPFunction, and I click on one, I get an error:

I guess I did not properly define the metamodel behind. But I do not see what is wrong. Here are the definitions:

PCPPObject class>>annotation

<MSEClass: #PCPPObject super: #MooseEntity>

<package: #ProfilerCPP>

^ self

PCPPFunction class>>annotation

<MSEClass: #PCPPFunction super: #PCPPObject>

<package: #ProfilerCPP>

^ self

Is this not enough? Why is there a call to mooseDescription? Help appreciated

Cheers,

Alexandre

Ah yes!!!!

Good point!

I forgot this point.

Would it make sense to have a check as follows?

complexPropertyPragmas

| navProps definedProps |

self mooseDescription ifNil: [ Error signal: 'Moose description are not initialized. Have you refreshed the meta-model? (e.g., MooseModel resetMeta)' ].

navProps := (Pragma allNamed: #navigation: from: self class to: MooseEntity)

sorted: [ :a :b | (a argumentAt: 1) < (b argumentAt: 1) ].

definedProps := (self mooseDescription allAttributes reject: [ :a | a type isPrimitive ])

flatCollect: [ :prop | 

(prop mmClass implementingClass >> prop implementingSelector) pragmas

select: [ :each | each keyword beginsWith: 'MSEProperty:' ] ].

^ (OrderedCollection withAll: definedProps)

addAll: navProps;

yourself

I can commit. 

Cheers,

Alexandre

Yes, that's enough. But, if you created these classes from scratch, you should also ensure that you refresh the meta-model :).

You can do it from the menu of the Meta Browser, or you can just execute:

MooseModel resetMeta
