-------------------------------------------
> variables not resetting if set to null
> --------------------------------------
>
> Key: VELOCITY-288
> URL: https://issues.apache.org/jira/browse/VELOCITY-288
> Project: Velocity
> Issue Type: Bug
> Components: Engine
> Affects Versions: 1.4
> Environment: Operating System: All
> Platform: All
> Reporter: Kevin Ward
> Assigned To: Velocity-Dev List
>
> In a loop over values in an array a variable is set to a non-null value. When
> a subsequent value is null, the initial variable retains the previous value
> rather than being set to null.
> Example:
> #set ($array = [ "hello", $null, "tomorrow" ])
> #foreach ($item in $array)
> #set ($text = $item)
> <pre>
> array: $item
> text: $text
> </pre>
> #end
> For this code, the output is:
> array: hello
> text: hello
> array: hello
> text: hello
>
> array: tomorrow
> text: tomorrow
> However, the output *should* be:
> array: hello
> text: hello
> array: $item
> text: $text
>
> array: tomorrow
> text: tomorrow
