Names beginning with underscores (with the exception of the _ namespace itself) are illegal in DTML Scripting. This is part of the security design. Instead, you can write an External Method for use in your ZClass "constructor" to do this.

-----Original Message----- From: Alex Rice [mailto:alrice@swcp.com]

When using my own python classes as base classes for ZClasses, I want to handle constructors. So, I figured I would add:

<!--#call "baseClass.__init__(self,...)"-->

after the #with ... createInObjectManager() in my ZClass "constructor" dtml method.

But, Zope takes issue with that method name when I commit the dtml, raising a TypeError. Is there a way to call constructors from dtml methods or elsewhere in ZClasses? Other inherited methods (other than constructors) give me no troubles. Here is the traceback:

... File /usr/share/Zope-2.0.0a4-src/lib/python/DocumentTemplate/DT_Var.py,line 307, in __init__ File /usr/share/Zope-2.0.0a4-src/lib/python/DocumentTemplate/DT_Uti l.py, line 337, in name_param (Info: ({'': '"baseClass.__init__(self)"'}, 'call', 1, 'name')) File /usr/share/Zope-2.0.0a4-src/lib/python/DocumentTemplate/VSEval .py, line 167, in __init__ (Object: baseClass.__init__(self)) TypeError: illegal name used in expression

Thanks for any advice on this,
