FW: [Zope] Form processing in Zope

[Kevin Teague]

There are two ways around avoiding the <dtml-if "ActionList == 1"> NameError
problem that I know of:

1. Wrap your if statements with another if statement:

<dtml-if ActionList>
<dtml-if expr="ActionList == 1">
Do this
<dtml-elif expr="ActionList == 2">
Do that.
</dtml-if>
</dtml-if>

2. At the top of your script, if an form value expected by your script
doesn't exist, set it to something:

<dtml-unless ActionList>
<dtml-var "REQUEST.set('ActionList','some_default_value')">
</dtml-unless>
