Wrong position using underscore in state name

[RK62]

Using adapter version 1.0.4.

I tried to show a position with states created with javascript and it seems that an underscore (_) could not be used:

• javascript.0.test.pos1 → works fine
• 0_userdata.0.test.pos1 → doesn't work

Both states contain the same values: The drop is OK, the fire ist wrong
