The Same SelectItem Control on Multiple Pages...
I need to put the same dropdown(selectitem) on multiple pages. I am using selectitems-1.1.0rc1. I have successfully place the dropdown on one screen. I am able to populate it and pull the selected value from it. Now, I need that same dropdown on another screen. In in my working screen, I use RoomServiceBean to call the DB and get a List:
<h:selectOneMenu value="#{person.room}" converter="org.jboss.seam.EntityConverter" required="true">
<f:selectItems value="#{rooms}" />
<h:message for="room"/>
</h:selectOneMenu>
where room is an attribute of the entity bean person.
Now my new screen looks like this:
<h:selectOneMenu value="#{attendanceService.room}" converter="org.jboss.seam.EntityConverter" required="true">
<f:selectItems value="#{rooms}" />
</h:selectOneMenu>
So "rooms" gets looked up in Seam and populated by the RoomServiceBean, b/c thats where rooms lives. But "attendanceService.room" seems to be conflicting with another room somehow.
Here is RoomServiceBean.java:
