Hi
Ordinastie take a look :

unless you use internal shape variable, no curves are being drawn, and when you use it, u can only draw single curve and not more than 1 in a component :/

Now, If i try to add my own version of drawing curves to your component, i get the error bellow, seems that two systems are fighting eachother.
