Referring pattern in different .eiq file error #228

Closed OszkarSemerath closed 11 years ago

OszkarSemerath commented 12 years ago

An unavailable referred pattern cause a "Couldn't resolve reference to Pattern '____'." error. If the pattern is created in a different file, the error doesn't disappear.

For example in file a.eiq:

//pattern fruit(F) =
//{
//  Fruit(F);
//}

b.eiq:

pattern c2(X) =
{
    find fruit(X);
}

And uncommenting the pattern in a.eiq doesn't make the error go away. Using the content assist or cleaning the project solves the problem.

Seems to be related to #193

In my case they are in the same package.

Sadly, the recent changes did not solve this issue. If an cross-file reference is removed, it is not re-added automatically if it re-appears. This is caused by the fact, that removing the pattern destroys the cross-reference information, that cannot be recovered without explicitly re-parsing the erroneous files (content assist or clean does that).

I have no real idea how to tackle this issue.
