In the SDF grammar of the sample project of Spoofax,
Ctrl-click on term Definition such as :

“module” ID Definition -> Start {cons(“Module”)}

drives the selection on the definition of “Definition”.

However if one adds a * after Definition :

“module” ID Definition* -> Start {cons(“Module”)}

Ctrl-clicking on it does nothing. I guess it is the same for +.

Adding parentheses around “Definition” does not help:

“module” ID (Definition)* -> Start {cons(“Module”)}

On which version of Spoofax does this occur?

Tested both on current stable ( and current unstable (same version).

Tested with the nightly build
The same problem occurs.

The versionf Eclipse that I use is Version: 3.7.2 Build id: I20110613-1736

Do you want me to try with an other build?

I’ve noted that when star (*) and plus (+) operators applies to sequence of symbols. Ctrl+Click works correctly.
We have to investigate the special behaviour of the ‘reference’ mechanism in Spoofax editors, in the special case of “unary operator” constructs.

I’ve noticed that StrategoReferenceResolver.ALLOW_MULTI_CHILD_PARENT is set to ‘false’ since r22534. Reverting it back to ‘true’ gives the correct behaviour.
I don’t know the implications of reverting it to ‘true’. Maybe LennartKats, who made this modification, can elaborate.
