The getUnassigned* methods retrieve features that are not currently assigned to the provided user (through the lh context). These methods are handy when you must create a User form that offers the user to select, and thus request access to, a feature they currently do not have. For example:
<Field name=’waveset.resources’>
<Display class=’MultiSelect’ action=’true’>
<Property name=’title’ value=’_FM_PRIVATE_RESOURCES’/>
<Property name=’availableTitle’ value=’_FM_AVAILABLE_RESOURCES’/>
<Property name=’selectedTitle’ value=’_FM_SELECTED_RESOURCES’/>
<Property name=’allowedValues’>
<invoke name=’getUnassignedResources’ class=’com.waveset.ui.FormUtil’>
<ref>:display.session</ref>
<map>
<s>current</s>
<ref>waveset.resources</ref>
</map>
</invoke>
</Property>
</Display>
</Field>
