Get row(id) of changed inputfield of a table
I have an inputfield in a tablecolumn of a table. If this field of a row is changed by a user I want save the change. Is it possible to get the position of the changed field although the row is not selected. Therefore the lead-selection doesn't help.
I saw that there exists an attribute 'm_index' with the required info in the context_element, but it is protected and i can't find any method to get this attribute.
Can I get the row(id) without selecting the row?
thanking you in anticipation
