Often when I select multiple object (either with the mouse or ctrl + click) and then I try to copy paste (to duplicate them) it doesn't work and the error I get is this:

SYSTEM ERROR! * this.canvas.currentController is null at: chrome://pencil/content/xferHel per/targetSetXferHelper.js:50

Seems to happen mostly when a Sketchy table is involved and when I click somewhere on the canvas prior to pasting (instead of just doing a ctrl+c and ctrl+v straight away with the current selection).

I would consider this a high priority bug. Also the fix is very easy.

on line 50, instead of passing in

Util.getMessage("action.create.shape", this.canvas.currentController.getName())

as the argument, if you replace the above with "", it works.

If you are a Windows user then you can find the targetSetXferHelper.js file in

C:\Program Files\Evolus\Pencil\app\content\pencil\xferHelper\

I am sure that the Linux directory structure is similar so you should be able to work out where the file is.

Do I need to replace this whole part of line 50, "Util.getMessage("action.create.shape", this.canvas.currentController.getName()" with just ""?

Or just the "action.create.shape" part?

I didn't get this to work.

Thanks to the fixer. Sorry richard for not replying. I have tried the newest version 1.3.3 from the download page and it is fixed.
