Seam2.2.2.final auto-generated entry pages have 'a4j:support' components attached to each field.
When the users enters a null value and tabs out of the field - and error message is displayed right away next to the field.
Bellow is an example which would fire the error display when the filelds get a null for a value and is tabed out:
<s:decorate id="numPatientsField" template="layout/edit.xhtml">
<ui:define name="label">Total number of patients</ui:define>
<h:inputText id="numPatients"
required="true"
value="#{aqipHome.instance.numPatients}">
<a:support event="onblur" reRender="numPatientsField" bypassUpdates="true" oncomplete="onAjaxRequestComplete()"/>
</h:inputText>
</s:decorate>
when upgrading to seam2.3.0.final / JSF2 /RF4 the 'a4j:support' got replaced with 'a4j:ajax' and now the error message is only displayed when the user clicks on the page's 'Save' button and the entire form is submitted.
<s:decorate id="numPatientsField" template="layout/edit.xhtml">
<ui:define name="label">Total number of patients</ui:define>
<h:inputText id="numPatients"
required="true"
value="#{aqipHome.instance.numPatients}">
<a:ajax event="blur" render="numPatientsField" bypassUpdates="true" oncomplete="onAjaxRequestComplete()"/>
</h:inputText>
</s:decorate>
What's the way to make the upgraded version display the error message at value entry as it did previously ?
I tried the way RF4 way explaned here using 'rich:validator' ("http://showcase.richfaces.org/richfaces/component-sample.jsf?demo=clientValidation&skin=blueSky")- that did not work.
