Martin Schwaiger updated VELOCITY-655:
--------------------------------------
Description:
I've found 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 difference 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
