Parameterized Producer question?

[pieter.martin]

Hi,

I have the following producer and injection point

     @Produces
     public ModelSolution<DataVector<Double>> getModelSolution() {
          return this.modelSolution;
     }

...

     @Inject
     private ModelSolution<DataVector<Double>> modelSolution;

This fails on startup with the following exception,

Exception in thread "main" org.jboss.weld.exceptions.DefinitionException: WELD-000023 Type parameter must be a concrete type:  public com.rorotika.ci.model.ModelSolution com.rorotika.executor.ci.CIExecutor.getModelSolution()
     at org.jboss.weld.bean.AbstractProducerBean.checkProducerReturnType(AbstractProducerBean.java:180)

However if I remove the <Double> from <DataVector<Double>> parameterized part it works, The following code works.

     @Produces
     public ModelSolution<DataVector> getModelSolution() {
          return this.modelSolution;
     }

...

     @Inject
     private ModelSolution<DataVector> modelSolution;

Is this expected behavior?

Thanks
Pieter

That sounds a bit strange, could you please file a reproducible JIRA?

I think because of that http://seamframework.org/Community/LatestWeldShnapshotSvnBuildBootError

This is hard to detect Parameterized type. So Pete Muir roll back this Parameterized type detecing.

Agreed, I don't see why the type parameter should be required to be a concrete type.

This was already fixed in 1.0.1 Final :-)
