[jboss-user] [JBoss Seam] - Re: can factory methods have parameters?

It just doesn't feel "correct". | I don't think it's incorrect. This is what seam gen apps do. And my gut feel is you'll encounter less trouble this way.

The problem is, I don't know how to create the DataModel using a factory method that needs to take a parameter (ie, make the findCalculations method above be a factory). | Right, factory methods can't have parameters. "matt.galvin" wrote : | Alternatively, I could remove the method parameters and add an injected property: | @In private Integer categoryId | But then I don't know how to have the proper value injected for each of the dataTables. | You could (I'm pretty sure) do something like | @In(value="#{category.id}") private integer categoryId | However, I don't think you should use the @DataModel / @DataModelSelection approach here. The reason is you need multiple dataModels (one for each category), and @DataModel only gives you a single dataModel per variable. You could use multiple dataModels with a more traditional JSF approach, though I think your first idea is easier.
