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:
