RE: [Zope3-Users] ++skin++Boston bug
Hi Marco your part looks good to me. The use of widget_row in ObjectWidget not... What happen is, the Boston skin uses a table for rendering a label field block. Why this and not CSS. Simply because the left label side has a nother backgrund color. And this isn't possible with CSS. But doesn't matter if this make sense or not. You need to register a different widget_row like tempalte for the ObjectWidget. This tempalte should not use nested tables. This would mean that the second broken td, tr rendering part goes away. Please add also a issue in the bug tracker.

[Zope3-Users] Reference to a COM object (or other external resource) in a Zope object
Hi, I am creating a kind of Zope proxy to a 3rd party COM object (I'm accessing it using Pywin32 facilities). I have to store a reference to this object somewhere in my Zope object. But, for obvious reasons, this COM object cannot be serialized so I cannot put it in any attribute of my Zope object. On the other side, initialisation of the object on each request is too timecost-consuming. From what I read on the web and this list, _v_ fields won't solve my problem, because the _v_ field may be reset in any time, when (de)serialization occurs. So I have a question, which may be generalized: how to properly store/cache a handle or a reference to some OS resource, if I cannot create/alloc and destroy/dealloc it on every request? I have read somewhere that possibly I can use module variables for this purpose. Is it the 'right' way? ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

maybe this attribute ought to be called template instead of orderform ?

That's correct but perhaps a little to much.
Probably you are looking for something like this:
