Populating dropdown with Map rule

Question

Hey,
I am currently getting a list of users that belong to an admin role and looking up the individual fullnames to create a map to display the name in the dropdown but pass the accountId once the form is submitted. My rule is below however the result of my rule currently gives me this:
<List>
<Map>
<MapEntry key='id1' value=name1'/>
</Map>
<Map>
<MapEntry key='id2' value='name2'/>
</Map>
</List>
I really just want something like this so i can put it in the valueMap property in a dropdown:
<Map>
<MapEntry key='id1' value='name1'/>
<MapEntry key='id2' value='name2'/>
</Map>
Any ideas how i need to change my rule below:
<block>
<defvar name='idList'>
<invoke name='getUsers' class='com.waveset.ui.FormUtil'>
<ref>:display.session</ref>
<map>
<s>conditions</s>
<map>
<s>adminRoles</s>
<s>Role</s>
</map>
</map>
</invoke>
</defvar>
<dolist name='entry'>
<ref>idList</ref>
<map>
<ref>entry</ref>
<invoke name='getAttribute'>
<invoke name='getObject'>
<ref>:display.session</ref>
<s>User</s>
<ref>entry</ref>
</invoke>
<s>fullname</s>
</invoke>
</map>
</dolist>
</block>
