----------------------------------------------------
Key: JBSEAM-1152

Project: JBoss Seam
Issue Type: Bug
Components: JSF
Affects Versions: 1.2.1.GA

"Conversion Error setting value '1 2' for
'#{resourceCatalog.resources}'."
My env:
JBoss 4.0.5

Sun RI 1.2_04
I have two entity bean: Resource and ResourceCatalog:
Code:
@javax.persistence.Entity
@javax.persistence.Table(name = "RESOURCE_CATALOG")
@javax.persistence.NamedQuery(name = "ResourceCatalog.findAll", query =
"select resourceCatalog from ResourceCatalog AS resourceCatalog")

Snippet from components.xml:
Code:
<factory name="resource" value="#{resourceHome.instance}" />
<fwk:entity-home name="resourceHome"
entity-class="my.model.resource.Resource"
entity-manager="#{entityManager}">
</fwk:entity-home>
<fwk:entity-query name="resourceCollection" ejbql="from Resource"
/>
<factory name="resourceCatalog"
value="#{resourceCatalogHome.instance}" />
<fwk:entity-home name="resourceCatalogHome"
entity-class="my.model.resource.ResourceCatalog"
entity-manager="#{entityManager}">
</fwk:entity-home>
<fwk:entity-query name="resourceCatalogCollection" ejbql="from
ResourceCatalog" />
Snippet from edit page:
Code:
<h:selectManyListbox value="#{resourceCatalog.resources}">
<s:selectItems var="field" label="#{field.name}"
value="#{resourceCollection.resultList}" />
<s:convertEntity/>
</h:selectManyListbox>
I get validation error message when i try submit entity ResourceCatalog.
I start seam-ui from examples folders on my system configuration and it start successful.
I do not see different between these applications.
Also, I have success result when I use h:selectOneMenu and ManyToOne association.
