I've passed an NSArray, logInfo, of EO objects from a Direct Action to

I'm getting this error when the page loads:
java.lang.IllegalArgumentException: While trying to invoke the set
method
"public void ResultPage.setLogInfoItem(Log)" on an object of type
ResultPage
we received an argument of type
com.webobjects.eocontrol._EOCheapCopyMutableArray. This often happens
if you
forget to use a formatter.
What's this mean?
It might mean that logInfo is an array of _EOCheapCopyMutableArrays
instead of an array of simple EO's. This can happen if logInfo was
created by sending an array of EO's a valueForKey() message with a
to-many relationship key as the argument. If this is the case, you
must iterate through the array of EO's adding the to-many relationship
objects to a new array, probably only if they're not already in the new
array.
Aloha,
Art
