a4j:support and skip validation

[ajanz]

i got a inputtext with a4j:support. also i got a custom validator on it.

when a4j:support executes, validation is also executed. why? how can i skip validation? bypassudates = false is not an option because i need the new value.

code is like this

<h:inputText value="#{Page.text19}" label="Test" id="intext2" style="border-color:red" >
<f:validator validatorId="MyValidator" />
<a4j:support event="onchange" action="#{Page.update('a','b')}" />
</h:inputText>
