Support feedback: I created a JSF page like this <h:dataTable value="#{SampleBean.list}" var="entry"> <h:column> <h:outputText value="#{entry.id}"/> </h:column> </h:dataTable> When I now try to use the code completition to see what attributes/methods "entry" has (i.e. put the caret after "entry." and press CTRL-Space), it only works if SampleBean.getList is defined as public List<SampleEntity> getList() { but not if it is defined as public Collection<SampleEntity> getList() { In the latter case a totally different (and unexpected) list of choices is presented. One would expect the same list as with "List" as return type. I also testet it now with Selena, 7626 and it is even worse! In 7626, it does neither work with List<SampleEntity> nor with Collection<SampleEntity>. In both cases, wrong attributes are shown!
