--------------------------------------
Attachment: VELOCITY-655_ParameterProblem.vm
> Macro parameter value can't be changed inside a macro
> -----------------------------------------------------
>
> Key: VELOCITY-655
> URL: https://issues.apache.org/jira/browse/VELOCITY-655
> Project: Velocity
> Issue Type: Bug
> Components: Engine
> Affects Versions: 1.6
> Reporter: Martin Schwaiger
> Attachments: VELOCITY-655_ParameterProblem.vm
>
>
> I've detected a problem when changing parameter values inside a macro using
> velocity engine version 1.6.
> In my use case I have to lower the input string first and then do further
> processing.
> With version 1.5 of the velocity engine there were no problems to implement
> this use case.
> Here is an example which shows the differences between version 1.5 and 1.6:
> Template-Code:
> {code}
> #macro(testMacro $x)
> #set ($x = $x.toLowerCase())
> #set ($y = $x.toLowerCase())
> x=$x
> y=$y
> #end
> #testMacro('ABCDEFGHIJKLMNOPQRSTUVWXYZ-Testcase1')
> #testMacro("ABCDEFGHIJKLMNOPQRSTUVWXYZ-Testcase2")
> {code}
> Result with Velocity Engine 1.5:
> x=abcdefghijklmnopqrstuvwxyz-testcase1
> y=abcdefghijklmnopqrstuvwxyz-testcase1
> x=abcdefghijklmnopqrstuvwxyz-testcase2
> y=abcdefghijklmnopqrstuvwxyz-testcase2
> Result with Velocity Engine 1.6:
> x=ABCDEFGHIJKLMNOPQRSTUVWXYZ-Testcase1
> y=abcdefghijklmnopqrstuvwxyz-testcase1
> x=ABCDEFGHIJKLMNOPQRSTUVWXYZ-Testcase2
> y=abcdefghijklmnopqrstuvwxyz-testcase2
