Hello everyone, We had used ObjectAutoCompleteBuilder for a text field in a form in wicket 1.4 here its work fine, but right now we are migrating from wicket 1.4 to wicket 1.5.7 as well as wicketstuff 1.5.7. here on submit form, we get : *"is not a valid Serializable"* error.
why it comes? is we want to change any other things. Thanks in advance. Vignesh Palanisamy
