Hi all,
I'm using SEAM 2.0.0 from the CVS and it seems to have the same problem since version 1.2.1.
I have an EntityQuery object like that:
@Name("localities")
| public class LocalitiesQuery extends EntityQuery {
| private static final long serialVersionUID = -4255032277168197004L;
|
| private String[] restrictions = {"l.region = #{localities.region}"};
|
| private Region region;
|
| public Region getRegion() {
| return region;
| }
|
| public void setRegion(Region region) {
| this.region = region;
| }
|
| @Override
| public String getEjbql() {
| return "from Locality l join fetch l.region";
| }
|
| @Override
| public List<String> getRestrictions() {
| return Arrays.asList(restrictions);
| }
|
| @Override
| protected String getCountEjbql() {
| return "select count(*) from Locality l";
| }
|
| }
PROBLEM: If I try to read localities.resultCount with a restriction defined, I get the following error:
javax.faces.FacesException: javax.el.ELException: /admin/localities.xhtml @37,119 rendered="#{localities.resultCount == 0}": Error reading 'resultCount' on type com.rmemoria.drugman.LocalitiesQuery_$$_javassist_5

Watching the source code, it seems the resultCount construction is different from the resultList construction. It doesn't consider the restrictions at a first parser, but tries to pass the parameters during query executing.
