Wicket: automatic field validation does not work -

i have integer field , when enter non integer value (let's symbolic one) feedback panel should triggered automatically default message, not work, have call in onerror method of form method error().

this textfield, use:

requiredtextfield<integer> intfield =  new requiredtextfield<>      ("intvalue", integervalue,integer.class); 

this simple feedbackpanel:

fragment.add(new feedbackpanel("feedback")); 

it works when call method error() in method onerror() of form.

could show how create form , model use? far understand want bind model fields. best guess model not have property "intvalue".

you might want (re)visit wicket wiki "more on models".
