i'm using the component like this
c:Typeahead object="Contracting_Entity__c" destinationForSelectedId="Contracting_Entity_Id"/
apex:inputText id="Contracting_Entity_Id" value="{!contractingEntitySearchText}" /
apex:commandButton value="Go!" action="{!doContractingEntitySearch}"
rerender="block" status="status"/
All "doContractingEntitySearch" does is run a query that refers to the variable contractingEntitySearchText as a parameter
but instead of return the query results the page goes to a blank page and throws the error above
