ever happen to have a List of Maps that you would like to render as a select tag in html?
just make sure your action returns a List of Maps
heres how to do it:
<ui:select label="'Category'" name="'categoryId'" list="categorys"
listKey="'[OS:\'id\']'" listValue="'[OS:\'name\']'"/>
what about one huge Map?
<ui:select label="'State'" name="'stateId'" list="states/keySet"
listKey="'.'" listValue="'states[.]'"/>
