Description Torbjorn Norbye 2007-05-02 22:35:21 UTC 
Create a class with a method like this

    public List<Foo> getWhatever() {
        return null;
    }

Then do Tools | Create Unit Tests, I choose junit 4.x but possibly 3.x has the problem.

This will create a unit test skeleton for me. but, the test method for getWhatever looses the 
parameterized type!

It does

    List expected = null

rather than
 
    List<Foo> expected = null
Comment 1 Marian Petras 2007-08-03 20:12:20 UTC 
Confirmed.
Comment 2 Marian Petras 2007-09-10 17:59:27 UTC 
Partially fixed (in the trunk).

It will work now with the exception of parametrized types having at least one type parametrized
(e.g. List<Map.Entry<String,Object>>). This is a shortage caused by bug #105176.

This partial fix will go into NB 6.0 Beta 2.

Comment 3 Marian Petras 2007-10-08 14:06:35 UTC 
Fixed in the trunk.

Now that bug #115176 was fixed, I could make a proper fix of this bug.

Comment 4 Marian Petras 2007-10-08 15:21:26 UTC 
I just integrated a very simple fix of this issue - it is a one-line fix which effectively replaces all the other code
modifications mentioned in this bug report. The following patch removes the complex private method and replaces it with
a simple call of TreeMaker.Type(TypeMirror).
