The attached product can be imported from Zope 2.4.2 Linux, but not Zope 2.4.2 on Windows. (Import it in the folder /Control_Panner/Products) Well, this product is a bit strange, because it uses classes of itself, so in Linux zope must be rebooted in order that this product works well. But I am not sure this error I am having in Windows is related with this. I also have this same error importing the file .tar.gz generated by the "distribution" menu. This is the error: Zope Error Zope has encountered an error while publishing this resource.
