Hello guys,
I'm using Tiles 2.0.3, with MyFaces 1.1.5 and Tomahawk 1.1.5 into JBoss
4.0.5.
I'm trying to build a h:selectOneMenu, using f:selectItems to define it's
options, like in the following code:
<t:selectOneMenu id="compId" value="#{MyBean.objectId}"
required="true" >
<f:selectItems value="#{MyBean.objectItems}"/>
</t:selectOneMenu>
With the following code for my backingBean, it works fine:
public class MyBean {
private int objectId = 0;
private List<SelectItem> objectItems = null;
public MyBean() throws Exception {
objectItems = new ArrayList<SelectItem>();
objectItems.add( new SelectItem( 0, "" ) );
objectItems.add( new SelectItem( 1, "Object1 ) );
objectItems.add( new SelectItem( 2, "Object2 ) );
objectItems.add( new SelectItem( 3, "Object3 ) );
objectItems.add( new SelectItem( 4, "Object4 ) );
}
public List<SelectItem> getObjectItems() {
return objectItems;
}
public int getObjectId() {
return objectId;
}
public void setObjectId(int objectId) {
this.objectId = objectId;
}
}
But, if I change the objtecItems initialization, performing a Db search, and
using the results to populate it, like in the following:
public MyBean() throws Exception {
List<MyObject> objects = dbObject.doSearch();
objectItems = new ArrayList<SelectItem>();
for( MyObject obj : objects ) {
/* obj.getInt() returns an int, and obj.getString()
a String */
objectItems.add( new SelectItem( obj.getInt(),
obj.getString() ) );
}
}
I got an error when trying to load the page into jboss log:
15:01:03,610 ERROR [[jsp]] Servlet.service() for servlet jsp threw exception

But checking the tiles log, I've got the following exception:

And also the following exception (that I think it's thrown after tiles try
the old include method)

I've removed the jsf-libs that comes with jboss, packed all the needed jar
into my .war, and the error is still the same. Someone could give me a hint
on that?
Thanks in advance,
Alexandre
