10:52 a.m.
I've got two places on a page where I iterate lists of object. For each object I
output a button that allows them(in this case) to add a user and role to a domain
object(in this case, a research study-I work for a university). While in both cases the
datatable is populated, in the first instance when the aj4 buttons are clicked the backing
actions are not called. I don't know why.
This is the nonworking instance. It displays the output of a user search. In summary,
what it does is iterate through a list of members returned by the 'userHome'
object. Then, in the 3rd column, I obtain a list of all possible roles and iterate over
them, displaying the appropriate buttons tied to the appropriate methods.
| <rich:dataTable id="memberSelectList"
value="#{userHome.findByNameOrInternetID(memberSearchName).toArray()}"
var="possibleMember" rendered="#{memberSearchName.trim().length() gt
0}" rowKey="#{possibleMember.umnDID}" rowKeyVar="umnDID">

Members</f:facet>

This is the working list-it displays a list of current users. It obtains it's
array/list of user and roles directly from the Study object, then iterates over them. For
each returned user it also iterates over the list of roles.

value="#{viewStudyAction.study.getUserAndRole().toArray()}"
var="userAndRole" rowKey="#{userAndRole.user.umnDID}"

| #{userAndRole.user.name}

| <rich:column>
| <f:facet name="header">User Name</f:facet>
| #{userAndRole.user.userName}
| </rich:column>
| <rich:column>
| <f:facet name="header">Add or Remove Users from
the list of Study Members</f:facet>

administrativeRole)}" >

Any opinion would be welcome. This problem has stumped me for more than a couple of
days.
