This week's book giveaway is in the Java in General forum. We're giving away four copies of Think Java: How to Think Like a Computer Scientist and have Allen B. Downey & Chris Mayfield on-line! See this thread for details.
Hi all, i have a field in my app in which the user will have to write a number in the format ##/########-####. Ideally, when he clicks into the field, he is guided by displaying __/________-__ in the field.
This works almost with the standard components, except that in my app, the field is not required and if I use the default components I always get Conversion errors if when the field is empty.
Ok, so I wrote my own converter, which allows either correct or empty entries, but as soon as I associate my converter with the input text component, the helper mask does not show up anymore.
Any ideas what could be the problem? thanks in advance ben
