I would like to congratulate you for excellent run-time library, which is vey developer friendly and inform developer about error by human way. Instead only giving run-time error number like in 80S and 90S, it inform exactly about error by providing useful info which allow developer to quickly find The problematic area of his code.
I have done error with specifiing parent and run-time error library have informed Me, that this object can not have The children. So I have moved The problematic line to a right place, Excellent Job!! Java scripts are also very fast. I will try to find how to get textual info from widgets and how to detect click. There is procedure click in htmlwidgets unit.
I Am able to create as much input boxes as I will need.
