_______________________________________________________
Details:
(I don't know how 1.6 behaved in this case, but due to general wml behaviour
nothing should happen...)
The following code reproduces the bug:
[event]
name=start
{DEBUG_MSG ONE}
[gold]
amount=10 #ok
[/gold]
{DEBUG_MSG TWO}
[gold]
amount=$null #error
[/gold]
{DEBUG_MSG THREE}
[gold]
amount=$iGold #error
[/gold]
{DEBUG_MSG FOUR}
{VARIABLE iGold null}
[gold]
amount=$iGold #error
[/gold]
{DEBUG_MSG FIVE}
{VARIABLE iGold $null}
[gold]
amount=$iGold #error
[/gold]
{DEBUG_MSG SIX}
{VARIABLE iGold 10}
[gold]
amount=$iGold #ok
[/gold]
[/event]
The console error output is the same for all of the errors:
20091229 17:02:29 error scripting/lua:
/usr/share/games/wesnoth/data/lua/wml-tags.lua:129: attempt to perform
arithmetic on local 'amount' (a string value)
