datatable , with celledit update - has null value instead of the input

[meirdev]

Hi, with mojarra-2.2.13, as it's in the wildfly(10.1.0.Final), the event handler, with the following method [exactly the method as in the primefaces demo] -

Code: Select all

 public void onCellEdit(CellEditEvent event) {
      Object newValue = event.getNewValue();
 }

the newValue does not contains the input of the user, but contains null..

After some days of investigation, i got to what cause the problem:

while the execution of APPLY_REQUEST_VALUE it does the following actions:
1. Get the submitted value and insert correctly to the input component.
2. Override this value later while saving descendant state.

So, what hapened - now the input contains null instead of the input from the user.

And in source source level::

1. The decode of HtmlBasicInputRenderer, fill correctly the submitted value of the UIInput component, with the input.
2. the method saveDescendantState, the state does not exist in the

getStateHelper().get(PropertyKeys.saved)

, it becomes to be null.

so what happened, in the following piece of correct code,

Code: Select all

            state.setValue(input.getLocalValue());
            state.setValid(input.isValid());
            state.setSubmittedValue(input.getSubmittedValue());
            state.setLocalValueSet(input.isLocalValueSet());

it reset the value of the submitted value, so it comes to be null later, when the value is required.

i will clear, that my xhtml seems exactly as in the demo.
The only difference thay i see is the mojarra version.

Please advise, what should be done to solve the issue.

*Sorry if english is not nice, it's not my first language.

I have exactly the same problem on latest everything.
PrimeFaces 12.0.0.RC3 and Payara 2022.3 (Mojarra 2.3.14)

Can anyone help? This seems to be a common issue

I also have had issues with 'events' with PF 11.08 (EE & Jakarta) & Mojarra 3.0.0.SP04 on WildFly 26.x.

Always 'resolved to null":

Code: Select all

public void onTabChange(TabChangeEvent event) {
   LOGGER.info(">>>>> TabChangeEvent event = {}", event);
}

Code: Select all

SEVERE [jakarta.enterprise.resource.webcontainer.jsf.context] (default task-1) jakarta.el.PropertyNotFoundException: /index.xhtml @43,133 listener="#{tabsChangesController.onTabChange}": Target Unreachable, identifier 'tabsChangesController' resolved to null

Still errors with:
