Comparable<...> interface on class causing Alias.$(..) to return null

[gsubes]

With a plain ValueObject class, everything works fine, but when trying to use a ValueObject class that implements Comparable<...>, I get the following Exception:

Exception in thread "main" java.lang.IllegalArgumentException: target should not be null
 at com.mysema.commons.lang.Assert.assertThat(Assert.java:149)
 at com.mysema.commons.lang.Assert.notNull(Assert.java:60)
 at com.mysema.query.JoinExpression.<init>(JoinExpression.java:37)
 at com.mysema.query.DefaultQueryMetadata.addJoin(DefaultQueryMetadata.java:81)
 at com.mysema.query.collections.AbstractColQuery.from(AbstractColQuery.java:88)
 at com.mysema.query.collections.ColQueryImpl.from(ColQueryImpl.java:17)
 at test.TestCase.testComparable(TestCase.java:54)
 at test.TestCase.main(TestCase.java:17)

This is caused by Alias.$(...) returning null, which is then fed into from(...).
I've tested this with 2.1.2, 2.1.1 and 2.2.0-beta4.

See attached testcase which is itself a minimal eclipse project, thanks for your help.

Fixed in SVN trunk

I would like to benefit from this right now. Is there an estimate when 2.2.0-beta5 will be released?

Released in 2.2.0.beta5
