Nathan Bubna commented on VELOCITY-773:
---------------------------------------
You're right, $foreach is always on, as it (and its special properties) are
heavily used.
> Provide locally scoped #set variables

> Key: VELOCITY-773
> URL: https://issues.apache.org/jira/browse/VELOCITY-773
> Project: Velocity
> Issue Type: Improvement
> Components: Engine
> Affects Versions: 1.7-beta1
> Reporter: Michael Osipov
>
> Consider this snippet:
> <!-- Generated pushbutton groups -->
> #foreach ($group in $form.pushbuttonGroups)
> <div class="die-button-group" style="#coordinates($group)">
> #* *##foreach ($groupChild in $group.children)
> #* *##if (!$velocityHasNext)#set($turnPaddingOff =
> 'style="padding-bottom: 0px;"')#end
> #* *##if ($groupChild.class.simpleName == "Pushbutton")
> #* *#<div $!turnPaddingOff>
> #* *#<button type="submit" name="$groupChild.name"
> value="$groupChild.value"
> onclick="loadSubsequent()">#label($groupChild.label)</button>
>
> #* *#</div>
> #* *##end
> #* *##end
> </div>
> #end
> There is an inherent bug. After the first run of the outer foreach, the var
> turnPaddingOff is still available and will always set in the div tag. There
> is only one workaround. At the end of the outer foreach you have to set it to
> ''.
> #set should be available as a locally scoped thing in #foreach or other
> constructs.
