Client Side Validation supposed similar functionality - perform whole form
validation before submit. If validation fails, request declined with updated
error messages.

> The submit button is not enabled until all the required fields within the
> form/region are set properly.
> I can think of two ways to implement it.
> 1) add a new attribute to a4j:form/a4j:rigion to indicate that if this
> feature is turned on/off. In addition, new attributes could be added to
> indicate the ids of the submit button, and/or ids of the required fields.
> For example:
> <a4j:form id="myForm" enableSubmitButtonForRequriedFields="true"
> submitButtonId="btnId" requiredFieldIds="id1,id2..." />
> 2) add a new attribute to a a4j:commandButton to indicate if this feature is
> turned on/off. In addtion, new attributes could be added to indicate the ids
> of the form/region and/or the ids of the required fields.
> For example:
> <a4j:commandButton id="btnId" enableSubmitButtonForRequriedFields="true"
> parentidforrequiredfields="myForm" />
> The example showed above means after all the required fields are set properly
> with the form "myForm" the button is enable.
> <a4j:commandButton id="btnId" enableSubmitButtonForRequriedFields="true"
> requiredFieldIds="id1, id2..." />
> The example showed above means after all the required fields specified by the
> attribute "requiredFieldIds" are set properly the button is enabled.
> Of course, the attribute "enableSubmitButtonForRequriedFields" could be
> optional. So only the "parentidforrequiredfields" or "requiredFieldIds" is
> checked to determine if the button needs to be enabled/disable.
