Hi ,
I have a problem in the content assist that s work for me in simple models but in the complex models it doesn t work .
For example in the model below the content assist for the first block works fine
but the blocks inside the first block nothing works
Any idea how I can debug to know where the problem came from ?
if ( ( [ this ] . ${fieldName} ) == null )
Block
{
if ( this_ . getObjMode ( ) . equalsIgnoreCase ( IBusinessObject.DAO_MODE ) )
Block
{
return null;
}
else
Block
{
Block
{
[ this ] . ${fieldName} = new ${assoType} ( );
( [ this ] . ${fieldName} ) . setObjMode ( getObjMode ( ) );
return [ this ] . ${fieldName};
}
}
}

Hi,

did you adapt the content assist or does the out-of-the-box content assist does not work as expected?
In case you adapted content assist the entry point for debugging is the complete-method you implemented and which you expect to be used. If it is not called at all, a common problem is that you specified a type for the context object and the type used by the framework is a different one. Replace the specific type by EObject (with a type check and cast to the specific type used previously) and see if the method is called now.

This is as specific as I can get with the given information.

Yes I adapt the content assist for some rules and that s works fine in general but in some cases when I have a deep tree like if inside another that seems not working

Well,

everything I can suggest is alreadyas described in my first post. Debug whether the methods you expect to be called, are called, check whether the context element is as expected.

Hi Alexander,
I didnt understand well your proposal
I used the same grammar with the same content assists in an another eclpise with xtext 2.0.0 and that's works fine but for now I still work with 1.0.0
Is that a bug ? if so is there a way to solve it without migrating to 2.0.0 ?

Hi,

we have such "nothing works" situations too - there might be bugs on this in Xtext 1.0.x - migrating to 2.0.0 helped us.

Hi,

did you try to uninstall xtext 1.0.x

however if you are stuck to 1.0.x
you could try to make your grammar "less" ambigous
to get ca working again.
