TextField and MinimumValidator
I cannot seem to get a simple validation to work on a form. Using 1.4-rc5.
TextField<Long> testLong = new TextField<Long>("testLong", new
Model<Long>(0));
testLong.add(new MinimumValidator<Long>(0));
batchForm.add(testLong);
I want the text field to be validated as a number, and zero or greater.
*Problem 1:* If I remove the MinimumValidator, I get no feedback message if
I put a non-numeric character in the field, and no errors.
*Problem 2: *With the MinimumValidator I get a class cast error:
WicketMessage: Exception 'java.lang.ClassCastException: java.lang.Long
cannot be cast to java.lang.String' occurred during validation
org.apache.wicket.validation.validator.MinimumValidator on component
1:batchArchiveForm:testLong
Root cause:
java.lang.ClassCastException: java.lang.Long cannot be cast to
java.lang.String

I know the feedback messages are working since I have a RequiredTextField
set up and it is responding properly.
It must be something simple that I am missing...
Thanks.

Posted by Igor Vaynberg <ig...@gmail.com>.
some models, eg propertymodel, can tell the component automatically
what type it is bound to.
you can open a jira issue for other cleanup issues.

Great! Thanks!
I know you guys are super busy. One thing to put on the list would be to
update the wicket examples - FormInput.java
This is still using the NumberValidator and all it's various forms which
have been deprecated. I assume that I would have seen the setType() in
there if it were updated. Something in that older style must have taken
care of that since the examples still work.
