Hi,

I'm trying to use dymamic binding of maps to loop through a map and thus my page blocks.  But I'm getting a wierd error 

"Value 'core.apexpages.el.adapters.RuntimeTypeMetadataELAdapter@6149c49c' cannot be converted from core.apexpages.el.adapters.RuntimeTypeMetadataELAdapter to com.force.swag.soap.DateOnlyWrapper."

The looping part of the visualforce

<apex:repeat value="{!opp90Map}" var="category" >     
        <td width="25%" valign="top">
    	<apex:pageBlock title="Top 90 Opp for {!category}">
     <apex:pageBlockTable value="{!opp90Map[category]}" var="opp">

and the map 

public Map<String, List<OppWrapper>> opp90Map {get; set; }  
        repNameList = new List<String>{'Brit', 'Emma', 'Jeanette', 'Kara'};
        opp90Map = new Map<String, List<oppWrapper>>();

the whole thing is a bit too big, but I include for completion sake

Thanks,
