"Cannot read from XML stream, wrong format: com.rapidminer.operator.ContainerMode"

HI guys, i keep getting this error message "Cannot read from XML stream, wrong format: com.rapidminer.operator.ContainerModel : com.rapidminer.operator.ContainerModel."

Seems that my colleague used an old version , now he added his plugin to my new version, still the mod file he generated, are start with
<object-stream>
<com.rapidminer.operator.ContainerModel id="1">
instead of
<object-stream>
<com.rapidminer.operator.learner.tree.TreeModel id="1">

do you know how to fix this? i am pulling my hair:(

Thanks!!
TJ

Hi,
I guess it's how you described: He simply writes a Tree Model instead of a container Model and the ContainerModel Reader you are trying to utilize does not cope with that. Use the Model loader or the IOObjectReader instead.
