oncomplete action occurs even after valitation failed

[fabulous]

Hi, everybody.

I've just coped with such kind of problem: I have a form with some fields and button(a4j:commandButton).I placed a validator inside a text box component. My button has an oncomplete attribute where the new rich:modalPanel will be full-screen displayed.It also has a rerender attribute which is supposed to update the view of that form. So the problem is: even after a validation failed oncomplete action will be performed and the new form will be displayed. But I want oncomplete action not being inplemented if there is a wrong value in the edit box... So If there are any ways to resolve this bottleneck? Please help me.

<rich:messages style="color:red" showDetail="true" styleClass="error"/>

<h:inputText id="vin" value="#{jobTicketBB.vehicle.vin}">
<f:validator validatorId="VinValidator"/>
</h:inputText>

<a4j:commandButton action="#{jobTicketBB.configureSelectVehiclePage}"
reRender="jobTicketModalPanel" actionListener="#{jobTicketModalFormSupportBB.openVehiclePage}"
oncomplete="showModal('jobTicketMain', 'jobTicketModal')"
value="#{jobTicketMsg}"/>

use something like

 <a4j:commandButton value="Validate" oncomplete="if (#{facesContext.maximumSeverity==null}){alert('Hi')}"/>

[ilya_shaikovsky]

call the modal instead alert

Many thanks. But I've already sort it out.

function showModalForm(mainPanel, modalShow, messageId) {
 if ($(messageId).textContent == "") {
 $(mainPanel).style.display = 'none';
 $(modalShow).style.display = 'block';
 }
}

I call this method on oncomlpete action of the ajax button

 <a4j:commandButton
 oncomplete="showModalForm('jobTicketMain', 'jobTicketModal','jobTicketForm:error')"
 value="#{jobTicketMsg['jobticket.edit.btn.carFind']}"/>

where the last parameter is for rich:message

<rich:messages style="color:red;" ajaxRendered="true" id="error"/>

I was very pleased that my sole helper is my fellow-townsman...
