M2Doc: Support of OCL Commands

Question

Hi together,

is it possible that some OCL commands are not supported in M2Doc?

Because if I try the following in the OCL Console it works:

self.user_redundancy.oclIsKindOf(sysml::SysMLPart)

-> result is true or false

But if I want to check this in M2Doc with an if-statement:

{m:if component.user_redundancy.oclIsKindOf(sysml::SysMLPart)}

...

I get an error that if-statements must be Boolean.

Thanks for your help.

Regards Yannik

Hi Yannik,

How is the property user_redundancy defined? Is it a derived property or a reference property and if the latter one, does it have multiplicity allowed?

Interesting, I am pretty sure that this should be supported. Anyway, M2Doc supports AQL which is not really OCL though quite similar, see  Acceleo (eclipse.org) .

According to this doc, oclIsKindOf is supported and should return Boolean:

Maybe (only a guess, I cant currently tets or verify this) the expression evaluates to "void" resp. "undefined" for some reason?
