Code problem between windows-versions ??

[artmusicstudio]

hi,
i have a strange problem:

in windows vista / skp 8 and skp 6 this peace of code (within the whole ruby) works perfectly (the group is copied, named and transformed copy-times:

angle = @arena_angle_half*2
		puts angle

		entities = @group_stair.entities
		group_arena = entities.add_group

			for copy in 1..@arena_angle_devider
			angle1 = copy *  angle
			group = @group_stair.copy
3863			group.name = "arena-copy" + copy.to_s
			tr = Geom;;Transformation.rotation(point,vector,angle1)
			@entities2.transform_entities(tr, group.entities.to_a)
			end

to my surprise, it does not work on

win 7 / skp 8
win xp / skp 8

this error is reported in the console

Error: #<NoMethodError: undefined method name=' for nil:NilClass> C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/01.rb:3863:in arena'
C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/01.rb:3860:in each' C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/01.rb:3860:in arena'
C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/01.rb:212

has anybody an idea, what this problem could be?

thank you very much!

Do you have the same plugins installed in all the SketchUp versions. sounds like you are suddenly getting a nil from @group_stair.copy - there might be some plugins that override this and change it's behaviour.

hi tt, although i synchronise the plugin-folders carefully,
making the win7 folder empty in deed was the solution.

so now i have to find out , which plugin has a conflict and can correct my code.

it was the first time, something like that happend. interesting!

thanx a lot for your "expert's eye".

ps: i just wonder, where to send all the cookies afterwards,,,,

You try to search the RB files for "class Sketchup::Group" or "def copy" - hoping the culprit is not scrambled. Might same you some investigation time.

hi,
problem solved, it was sketchy physics. i will try to redifine my code later, maybe i will find the problem.
