Why I am getting value for the param assignTo?

I am iterating  a map using repeat on a vf page. I want to send the selected folder's id in the apex. I tried to use param but it is giving null values.Following is my code:
Page: 
<apex:pageBlockSection id="FolderName" collapsible="true" title="Folder">
				<apex:repeat value="{!foMapNames}" var="fokey">
					<apex:commandLink value="{!foMapNames[fokey]}" action="{!folderIn}" reRender="none">
						<apex:param value="{!fokey}" assignTo="{!foId}"/>
					</apex:commandLink>
					<br/>
				</apex:repeat>
			</apex:pageBlockSection>

here fokey is null.

Change as below 
  
<apex:pageBlockSection id="FolderName" collapsible="true" title="Folder">
				<apex:repeat value="{!foMapNames}" var="fokey">
					<apex:commandLink value="{!foMapNames[fokey]}" action="{!folderIn}" reRender="none">
						<apex:param value="{!foMapNames[fokey]}" assignTo="{!foId}"/>
					</apex:commandLink>
					<br/>
				</apex:repeat>
			</apex:pageBlockSection>

I want to send the key i.e; fokey to the apex, not the value of the map corrosponding to the fokey.
