I am having a rather surreal time here. I am attempting to write a ZPT version of standard_error_message under Zope 2.5.0 and I find that I cannot display the options/error_value field. If I dump out the entire options dictionary, error_value is there and gets displayed as something like <Products.PageTemplates.TALES.Undefined instance at 0x831c384>, but if I attempt to render it in ZPT (just using what the CMF folks did) I get a generic error message of some kind. DTML has no trouble rendering the same thing as a file/line type error message but ZPT blows chunks. Any hints greatly appreciated.
