Wicket Noob: Long cannot be cast to java.lang.String
Hello Wicket dev, gurus and mortals, I was successfully using Wicket to build the UI for my new web-app gig. I have studied the javadoc: org.apache.wicket.markup.html.form, org.apache.wicket.MarkupContainer and others until bleary-eyed. The web-page I am using will display correctly the values for Long and Integer in a HTML text input dialog but when I try to Save (write the value back to the DB) I get the following error condition. I can only work with String data and nothing else using the wicket ids. Please advise, David.
**************************************************************
org.apache.wicket.WicketRuntimeException: Exception 'java.lang.ClassCastException: java.lang.Long cannot be cast to java.lang.String' occurred during validation org.apache.wicket.validation.validator.StringValidator$MaximumLengthValidator on component 1:editform:weight at org.apache.wicket.markup.html.form.FormComponent.validateValidators(FormComponent.java:1510)
There are 10 kinds of people in this world: those who understand binary and those who don’t (Valid only for 2's complement).

I'm referring to the days of no JSP on AS400 boxes. The only option was to out.println() from a Servlet or some Serializable object a whole bunch of HTML and then do HTTP GET URL daisy-chain to another Servlet. ;-)

Hello Johan, thanks! the static NumberValidator.RangeValidator(long minimum, long maximum) worked! Wicket is great. I just wished Wicket was available 10 years ago! Regards, David.

You seem to have a String validator on a number field. What do you
want to test a range? Or max value of that long? Use a different
validor
