Hi, I am using JBDS v2. The Seam support is great, but there seem to be a reasonable number of flaws in the validation. To list a few: ERROR: Duplicate variable name when using @DataModel and @Factory: @DataModel public ArrayList bookingsForApproval; @Factory("bookingsForApproval") public void findBookingsForApproval() { bookingsForApproval = new ArrayList(forApprovalBookings.getResultList()); } WARNING: "0" cannot be resolved in #{featuredFeedback.resultList[0]} WARNING: components declared in components.xml cannot be resolved. This includes entityManager (i.e. @In EntityManager entityManager gives a warning), identity and a number of central components, as well as user-specified components. WARNING: pages.xml validation #{s:hasRole('blah'} gives 2 warnings, one that s cannot be resolved and another that hasRole can't be resolved All actions such as: #{webpageHome.setId(15)} give validation warnings - seems it doesn't like method expressions. The project runs fine ignoring these errors, but it's irritating that genuine problems can be masked by these. Any chance of fixes?
