<h:inputText id="quantity"
value="#{_cartItem.quantity}" required="true" size="3"
maxlength="3">
<f:converter converterId="ValueConverter" />
<f:validateLongRange minimum="0" maximum="999" />
<a:support event="onchange"
    ajaxSingle="true"
    action="#{cSession.userCheckQuantity(_cartItem, index)}"
    reRender="minicartAjax, shoppingCartAjax, orderTotalAjax"></a:support>

When you click off the Quantity input box the userCheckQuantity method is easily fired. But If I put in a number and quickly slam down the enter key on the keyboard the validation is missed.

How can I get the Enter key approach to validate as well? Let me know if I need to provide more code.

    You’re doing the validation by Ajax exclusively. This is not robust enough. You need to replace the action="#{cSession.userCheckQuantity(_cartItem, index)}" by a fullworthy Validator implementation which you bind to the input component as a <f:validator>. This way the validation will always take place, regardless of whether it’s been triggered by a change or a form submit.

    Inside the Validator implementation, you could obtain the _cartItem and index from the FacesContext. How exactly depends on where they are stored and what JSF spec version you’re using. If they’re for example stored as request attributes, you could use ExternalContext#getRequestMap() to get them.
