I have this example http://tinyurl.com/nay2rnr I am trying to validate asynchronously the username. So on changeValue of that field I call a function that asynchronously validates the username and if it is invalid it throws an error. Unfortunately since the call is asynchronous, when the function returns the caller has long ended so there is no one to catch the exception. How can I handle the exception?
I know I can handle the valid state of the item right there in the async function but I want to know what is the proper way to handle asynchronously the exception. Also how can I use that function in a DRY way? The closer I came up is this http://tinyurl.com/o2r56zv but when I press send, even if the field is invalid I get "You can send" first and later I get "Nope..." ------------------------------------------------------------------------------ _______________________________________________ qooxdoo-devel mailing list qooxdoo-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/qooxdoo-devel
