 Status: Pending => Wontfix

We will not extend the functionality of DTML. DTML is dead and should only be used for ZSQL methods. Use ZPT in all other cases.

In ZPT files one can call methods from modules.

For example :

<tal:block define="res python:modules['Products.OneMoreUtilProduct.integration'].isProductPresent('Products.CMFCore')">
  <tal:block replace="res"/>
</tal:block>


In DTML files one cannot call methods from modules.

For example one cannot do :

p {
<dtml-if "modules['Products.OneMoreUtilProduct.integration'].isUserAgentGecko(REQUEST)">
-moz-border-radius: 4px;
</dtml-if>
}

NameError: name 'modules' is not defined

If it's possible in ZPT files, it should be possible in DTML files too. Because one cannot use ZPT files for all usages. For example one should use DTML files for writing CSS declarations.

I'm attaching the archive OneMoreUtilProduct.tar.gz containing a Zope Product to test module calling both in ZPT and DTML.

Thank you if you can fix this.
