Widget input min and max values don’t work with variables.

When I put a variable, obtained from process variable or BDM as minimum or maximum value in widget input (number) the form is not validated correctly.
someone has the solution?
Thank you.

I answer myself.
Despite this error, if it is indicated an expression (variable + integer for example) it does work fine.
I put in he maximum value: variableName + 0
It works also with BDM.variable + 0

I have created the issue BBPMC-296.
