entity-query : resultCount problem with join fetch

rmemoria May 24, 2007 10:49 AM

Hi all,

I'm using SEAM 1.2.1GA and JBOSS 4.0.5GA

I've declared an entity-query component in components.xml like that:

<framework:entity-query name="products" ejbql="from Product p join fetch p.drug" order="id" />

but when I try to read the property stocks.resultCount in my pages I get the error:

javax.faces.el.EvaluationException: /admin/products.xhtml @25,117 rendered="#{products.resultCount == 0}": Exception getting value of property resultCount of base of type : org.jboss.seam.framework.EntityQuery_$$_javassist_29

Implementing a class inherited from EntityQuery solved the problem, but it's easier for me to declare it in components.xml

Any tip?

Yew, thats a bug, please report it in JIRA. But .... I don't see any good solution, apart from parsing the whole query....

We have encountered the same/similar error. As a work around I added:
@Transactional @Override public Long getResultCount() { Long fromInt = new Long(this.getResultList().size()); return fromInt; }

Not the 'correct' solution, but it appears to work. Has a JIRA issue been opened?
