I had the same problem and here is the solution: let's suppose you have those 2 TextField one of them called apiurl and other called mainUrl ! all what you have to do is to to create String url = ""; and go to your button action and add this line : url=apiurl.getText(); in the initialize method in your controller add this : apiurl.setText(url); and this worked well for me !

@kleopatra no I tried this solution that you propose and it did not work – maryem neyli May 25 '20 at 08:45
then you did something wrong - passing parameters around (with one of the various options mentioned in the referenced answer) does work _always_ As an aside: you seem to have a very effective crystal ball - this answer has no relation to the question and still is accepted ;) Aside: in case you are the same person as the OP with two accounts: the moment you start upvoting between those accounts you are violating the rules of the site and might get in trouble, just saying .. – kleopatra May 25 '20 at 09:09
@kleopatra in my case since my variable is needed to be used in other class I put it static but in her case truly she can delete the "static" key word! I updated the response – maryem neyli May 25 '20 at 10:15
just stating the obvious - there is __no__ relation between the question and this answer ;) If you consider facts as rude I can't help it *shrugs – kleopatra May 25 '20 at 10:21
