Primefaces Press Enter executes commandButton

Question

I am working with primefaces and I have the following problem, I have a toolbar with several buttons and components like inputtext and others in the form, but when I press the key Enter in some component the first button of the toolbar is called, in this case commandbutton "idButtomNuevo" is called because it is in the first position.

My code:

almacen.xhtml

<ui:composition

 <h:form id="idFormAlmacen" >
    <p:focus context="idFormAlmacen"/>
    <p:growl id="growl" showDetail="true" life="2500" for="keyAlmacen" globalOnly="true"/>
    <p:panel header="Almacen" styleClass="texto-panel"/>
    <ui:include src="/pages/logistica/almacen/toolbar_almacen.xhtml"/>
    <ui:include src="#{almacenBean.pathbodyAlmacen}" />    
 </h:form>
 <ui:include src="/pages/logistica/almacen/dialogos_almacen.xhtml" />
</ui:composition>

Answer 1

This is not a JSF specific behavior, when Enter is pressed the first <input> with type="submit" is used. This has been discussed on SO (see this or this), I'll put here some of the suggestions from those threads.

Javascript solution:

Use <h:form id="thisform" onkeypress="if( event.keyCode == 13){event.keyCode=0;}"> on your form. This, however, will prevent you from having any default command on the form since it catches pressing Enter.

Primefaces solution:

Use a dummy button on the form which does nothing, and set it as form's default command.

<p:defaultCommand target="dummy"/>
<p:commandButton id="dummy" process="@none" global="false" style="display:none;"/>

I had the same issue in my project. To avoid the submit on enter key press I just did like following. At every inputText field added this code,

onkeypress="if (event.keyCode == 13) { return false; }"
