nubie issue: @In injection
Hi,
I have an issue relating to injection. The suspects are Entity:Casino, EJB Bean:UserCasinoListActionBean and JSF: userCasinoListAction.xhtml. The purpose of the bean is to search for a list of Casino entities and return them in a Richfaces dataTable. The data table outjection works fine however I can't seem to get the injection for the search parameter to work. Note that I checked the @Name annotations and tried @In(create=true) without success. If I just dump the injection object to log.info() its a null object and if I use it in the query i get the @In attribute requires non-null value
error. I would really appreciate your help as this is kind of making me crazy at this point.
