How to display multiple errors for same objects used more than once [message #893255]

Hi All,

I have a problem in highlighting errors (underlining errors with red line)for same objects used more than once.

I have code as below,

implement Dummy, Dummy, Dummy of Expansion;

I have implemented code to display errors for all the three elements (Dummy, Dummy, Dummy). The message appears thrice as expected however only the first element is underlined red where as I want all the three Dummy elements to be underlined red.

It works fine if Dummy is used in different line like the below code,

implement Dummy of Expansion;
implement Dummy of Expansion;

Could anyone please suggest a way to tackle this?

Hi,

in more recent versions of Xtext you can add the index of a list feature that is to be marked with the error. So rather than using
error(String message, EStructuralFeature feature)
you use
error(String message, EStructuralFeature feature, int index) using the appropriate index for every Dummy.

Hi Alexander,

Thanks for your answer! That did help but another problem occurs.

Now if I have,

implement Dummy, Dummy1, Dummy2 of Expansion;
implement Dummy1 of Expansion;

In the first line of code, Dummy1 is marked error which is right but in the second line the entire line is marked error instead of only Dummy1.

What could be the problem?
