submit only with inputText and without valueChangeListener

[Jana Wetzel]

Hello everybody,

i need some help for a problem I can't solved.

To submit a formular I can only used an inputText because of a barcode scanner. I start with the following code

<h:inputText id="inputField" value="#{inputHandler.inputField}" valueChangeListener="#{inputHandler.processValueChange}" onchange="submit();">
                 <h:outputLabel for="inputField" value="Barcode-Scan: " />
</h:inputText>

This code is working but I don't need a valueChangeListener. An ActionListener would be better, because I need every input also twice the same.

The element inputText don't offer an actionListener, so what can I do?

Can someone help me, please?

Bye Jana

Because it is just an input element, not some action element.
Add a h:commandButton to the form and specify the actionListener in there.

Hello Bauke,

That's the problem. I can't use a button because I have only a barcode scanner as input. No mouse, no keyboard.

Does a solution exist without button or commandLink?

Thanks for your help.

Well, continue misusing the valueChangeEvent then. That's the easiest way.
If you want the event to happen during the invoke application phase, so that it would behave like during actionListener, then you need to queue the event.

Something like

if (event.getPhaseId() != PhaseId.INVOKE_APPLICATION)) {
    event.setPhaseId(PhaseId.INVOKE_APPLICATION);
    event.queue();
} else {
    // Do your thing here.
}

Hello Bauke,

i misused the commandButton now

<h:commandButton value="submit" action="#{inputHandler.processValueChange}" type="submit" style="display: none"/>

Now the inputText do what I want.

Thanks for your help.
