[Zope] A ZPT newbie question

[Wankyu Choi]

Hi all,

There must be a better way than:

    <span tal:omit-tag="" tal:condition="python: this_object is not
None">
        <span tal:replace="python: this_object.getSomethingBig() " />
    </span>
    
The following gives an attribute error if 'this_object' is None:

    <span tal:replace="python: test(this_object is not None,
this_object.getSomethingBig(), '')" />
        
test() seems to always evaluate both params no matter what. 

In a word, is there a ZPT equivalent to the following python code
without nesting <span></span> again and again?

    if this_object is not None and this_object.getSomethingBig():
        result = self.getSomethingEvenBigger()
        
I'm putting too many <span></span> nests to prevent this annoying
attribute error in NeoBoard skins.

Any help will be appreciated.

Regards,
Wankyu Choi
