JSF validator

Front-end
#1

Gente , boa noite :stuck_out_tongue:
Queria pedir uma ajudinha rsrs
Estou com um projeto da facul, e estou com duvida sobre o JSF.
Esse validator, será chamado apenas quando eu clicar no CommandButton?

Como eu disparo esse validator sem ajax?

[code]<ui:composition xmlns="http://www.w3.org/1999/xhtml"

template=“index.xhtml”>

&lt;ui:define name="painel"&gt;
	&lt;h:form&gt;
	
    	&lt;p:panelGrid style="font-size:75%"&gt;  
    	
		    &lt;f:facet name="header"&gt;  
		    	&lt;p:row&gt;
		    		&lt;p:column colspan="3"&gt;
		    			Cadastro de Aeronaves
		    		&lt;/p:column&gt;
		    	&lt;/p:row&gt;
		    &lt;/f:facet&gt;  
		  
		  
		  
			&lt;p:row&gt;
			&lt;p:column&gt;Código:&lt;/p:column&gt;
			&lt;p:column&gt; 
			&lt;p:inputText id="codigo" value="99999" validator="cadastroAeronavesCodigoValidator" &gt;   
			&lt;/p:inputText&gt;
			&lt;/p:column&gt;
			
			
		    &lt;/p:row&gt;
				
			&lt;p:row&gt;

			&lt;p:column&gt; &lt;h:inputText  id="fabricante" value="99999"  required="true"/&gt;    &lt;/p:column&gt;
		    &lt;/p:row&gt;	
		    
		    &lt;p:row&gt;
			&lt;p:column&gt;Nome:&lt;/p:column&gt;
			&lt;p:column&gt; &lt;h:inputText id="nome"  value="99999" required="true" /&gt;    &lt;/p:column&gt;
		    &lt;/p:row&gt;	
				
			&lt;p:row&gt;
			&lt;p:column&gt;Quantidade De Assentos:&lt;/p:column&gt;
			&lt;p:column&gt; &lt;h:inputText  id="quantidadeAssentos" value="99999" validator="cadastroAeronavesAssentosValidator" /&gt;    &lt;/p:column&gt;
		    &lt;/p:row&gt;
			
			
		    &lt;f:facet name="footer"&gt;  
		    	&lt;p:row&gt;
		    		&lt;p:column colspan="3"&gt;
		    			&lt;p:commandButton type="button" value="Save" icon="ui-icon-check" style="margin:0"/&gt;  
		    		&lt;/p:column&gt;
		    	&lt;/p:row&gt;
		    &lt;/f:facet&gt;  
		    
		&lt;/p:panelGrid&gt;  
		
		&lt;p:commandButton value="Cadastrar" action="#{aeronaveController.printText}"&gt; &lt;/p:commandButton&gt;
		
	&lt;/h:form&gt;
&lt;/ui:define&gt;
