Andrea Del Bene updated WICKET-5708:
------------------------------------
Affects Version/s: 7.0.0-M3
> Making FormComponent.convertInput() public
> ------------------------------------------
>
> Key: WICKET-5708
> URL: https://issues.apache.org/jira/browse/WICKET-5708
> Project: Wicket
> Issue Type: Improvement
> Components: wicket
> Affects Versions: 7.0.0-M3, 6.17.0
> Reporter: Ilia Naryzhny
> Labels: convert
>
> Please make FormComponent.convertInput() public.
> Whole conversation can be found here:
> http://wicket-dev.markmail.org/message/eicsiw6akjxbfs3z?q=convertInput
> Some quotations:
> "My intent is following:
> Some form components should be shown or hiden dynamically according to
> entered information and(!!!) without touching underling models. Whole form
> content should be refreshed.
> To achive that I use following approach:
> 1) AjaxFormSubmitBehavior with event="change" to recieve form on server side
> 2) With the aid of FormComponent.hasRawInput() I can understand where to
> get actual value for the component: either by
> convertInput()->getConvertedInput() or directly from a model.
> 3) [HACK] if value should be taken from form component with the aid of
> reflection I'm invoking convertInput()
> Method convertInputMethod =
> FormComponent.class.getDeclaredMethod("convertInput");
> convertInputMethod.setAccessible(true);
> convertInputMethod.invoke(formComponent);
> I can't use "validate" because there are some validators on a components
> and they should be fired after actual data submition.
> Currently, whole that stack is working perfectly as expected. But that
> little hack is confusing me a bit:)"
> Andrea's answer:
> "If I understand correctly you submit form disabling default processing.
> In this way Wicket retains fields value without validating them but also
> without converting input. But you also need to convert the input value
> of the desired field. Right? I guess you have to do it because raw input
> is not enough for you."
> That description is absolutly correct. Please help by supporting this usecase
> in wicket!
