Here ma code:
<h:form>
<p:tabView dynamic="true" cache="false" activeIndex="#{tabManager.activeIndex}" >
<p:tab title="Employeur - Travailleur" id="firstTab" >
<ui:include src="./tab1.xhtml"/>
</p:tab>
<p:tab title="Occupation" id="secondTab" >
<ui:include src="./tab2.xhtml"/>
</p:tab>
<p:tab title="Summary" id="ThirdTab" >
<ui:include src="./tab3.xhtml"/>
</p:tab>
</p:tabView>
</h:form>
These 3 tabs share a managed bean called "article" with just properties like ( (name and description on first tab, price and quantity on second tab...).
The scenario is --> i'am on the first tab --> i go to the second tab without validate the first --> i'm back to the first then i valide and i receive error messages from data inside first tab(logic) but also error messages from second tab..

(problem).
my actions business is found in the article managedbean and i access via EL.
I hope that you can help me. Thank's
