Cool, thanks! I'll replace them with proper HTML syntax expr's. = Joe = Jim Fulton wrote:

I just upgraded from Zope 2.0.0 (stable version I believe) to Zope 2.1.0 and my site broke where I use
&dtml-expr="";
This was never correct usage. If it ever worked, it was a bug. When using the entity-regerance syntax in 2.0, you aren't allowed to specify any attributes. The form is:
&dtml-foo;
which is equivalent to:
<dtml name="foo">
syntax. I looked in the release notes for any changes to DTML syntax but noticed none which seem to cause my problem. (However, this same thing happened to me upgrading to 2.0.0 and the docs escaped my notice then so...) Basically, I'm using
<... &dtml-expr="Python calculations go here"; ...>
e.g.,
<TR BGCOLOR="#&dtml-expr="_.hex( 0xF8 - depth)[2:]";&dtml-expr="_.hex( 0xF8 - depth)[2:]";FF">
in several places. I noticed that the entity syntax has been upgraded with qualifiers. I've also tried a whole bunch of syntactic variations to get my &dtml-expr=""s to work, all to no avail. Finally, I've practiced newbie Zope Zen and tried to decipher DT_Var.py (or thereabouts) to see if I could figure out the fate of &dtml-expr. Anyway...
Has &dtml-expr="" been deprecated, i.e., removed from Zope, or have I just failed to find the new secret incantation which gets me an expression using the entity syntax?
It was never supported. I'm quite surprized that it worked.
Needless to say, any help appreciated. I don't mind changing my code, but I do need to know the new Zope 2.1.0 Zen of &dtml-expr="";).
The new and old Zope zen is that you can't use '&dtml-expr="";'.
Use <dtml expr="">. If you need to use an entity reference, then you need to use a with or let tag:
<dtml-with "_( bgcolor=_.hex( 0xF8 - depth)[2:] )"> <TR BGCOLOR="#&dtml-bgcolor1;&dtml-bgcolor1;FF"> </dtml-with>
