I also changed some calls to this method. Now I'm getting must specify an additional parameter error. I added set step on in btcc_ValStr method for btcc_container and it doesn't go to this point, it errors just before it. This method is defined only in this class, everythere down in hierarchy this method is empty.

Doh! I opened btcc_valrangenum and indeed the method was there!

So, the first part of the question is closed. I spent more than 1h. trying to debug it :(
