Nathan Bubna resolved VELOCITY-773.
-----------------------------------
Resolution: Not A Problem
No. This is by design. There are no more implicit scopes in Velocity 1.7+
All variables are now global scoped by default. Scoping is now done
explicitly. You can turn on the explicit scopes you want/need as listed here:
http://velocity.apache.org/engine/devel/developer-guide.html#Velocity_Configuration_Keys_and_Values
Then use them explicitly:
#set( $macro.foo = 'bar' )## will vanish when macro is done rendering
> 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.
