[jboss-user] [JBoss Seam] - howto: selectManyMenu and hql with EntityQuery

Hello, I have used seam gen to generate basic classes for an existing database model. Now I try to add a listbox with multiple selection. The backend class is extended from EntityQuery. The problem I have now: How can I add a multiple selection restriction string for the query? I have tried with a Long[] but the result is a class cast exception: the resulting select is not capable that he should receive a list but expects only one variable instead... | <h:selectManyMenu value="#{parameterList.categoryIds}"> | <s:selectItems value="#{paramcategoryList.resultList}" var="category" label="#{category.name}"/> | <s:convertEntity /> | </h:selectManyMenu> | | @Name("parameterList") | public class ParameterList extends EntityQuery { | private List<Long> categoryIds; | | private static final String[] RESTRICTIONS = { | "parameter.paramcategory.id in elements(#{parameterList.categoryIds})",}; | | @Override | public String getEjbql() { | return "select parameter from Parameter parameter"; | } | | @Override | public List<String> getRestrictions() { | return Arrays.asList(RESTRICTIONS); | } | | ... categoryIds getter and setter | } | An additional problem arises with building RESTful URL's: since I have a dynamic list of parameters for the GET URL I have not found a solution to add a suitable page parameter to page.xml. As a work around I use the JSF POST... Does anybody know how to add a page parameter that is capable of a selection list?
