my problem is the following, I have two methods, in the first method I fill a combobox with data from a table in a database, that method works very well, showing me all the records that I insert in combobox # 1, by which I want to pass through the combobox # 1 the value of the selected String in this and then pass it to fill the combobox # 2, for it I have a Query in the second method, where I capture the value of the first combobox to fill the second, but I have not been successful, the value is empty, I do not know if I'm doing the reference wrong or not.
here I leave the code to guide me.
