[Zope] Why can't this be done???

[Jochen Haeberle]

Stephen,

thanks for your tip! This makes things a bit better... at least no 
error and parts of the
included page do show up... but all the posted messages are missing !?!

So it's the following code (copied from the included page) that's not working:

><dtml-if children>
>  <dtml-tree branches="children">
>   <a href="&dtml-absolute_url;"><dtml-var title></a> by <a 
>href="mailto:&dtml-email;">&dtml-author;</a> on <dtml-var created 
>fmt=aCommon>
>  </dtml-tree>
><dtml-else>
>  <p>This discussion is empty.</p>
></dtml-if>

The dml-if does not give any result, not even the else-branch... and 
there are messages. If the included page alone is viewed, this
code works just fine...

Is this correct behaviour?

Would you please be so kind to explain what your tip using <dtml-with 
"PARENTS[0].disc"> does? Is this sort of stepping up to the
parent folder and then down again to disc? Why is this different from 
<dtml-with disc>?

Jochen
