Naftoli,
I must be doing something wrong. I tried the following, as you
suggested,
inserting the extra xml after the item:fields tag, but
ManagerUsers.list does its
own iteration through the table items and I get duplicate columns.
ManageUsers.list just does a bind to the myuser:roles tag.
<table:items>
<tr>
<item:fields fields="firstname lastname email" >
<td style="vertical-align: top"><field:form /></td>
</item:fields>
<lift:ManageUsers.list>
<td style="vertical-align: top"><myuser:roles /></td>
</lift:ManageUsers.list>
<td style="vertical-align: top"><item:removeBtn /></td>
</tr>
</table:items>
Then, I have the added problem of saving changes to the item, since
roles is not
a field recognized by ItemsList.save.
Any suggestions??
Kevin,
I implemented asmselect in my app and it works great.
Thanks for the heads up.
Glenn...
