Is posible to enable primefaces button after successful validation?

Is posible to enable primefaces button depending on the correct validation of inputText and without using jquery or writing the validation on a java class? I just looking for enable it in the view side and using several inputTexts I am trying with disabled="#{not facesContext.postback or not facesContext .validationFailed}" But maybe I am doing something wrong becouse is not working as I`m expecting. I have something like these but with 4 more inputTexts with similar code. 

    <p:inputText id="user" value="#{acc.user}" 
        required="true">
        <f:validateLength ... for="user" />
        <p:ajax update="msgUser" event="keyup" />
        <p:ajax update=":#{p:component('add')}"  />
    </p:inputText>
<p:commandButton id="add" update="dataTable"
    oncomplete="addConfirm.hide()" actionListener="#{managedBean.onCreate}" 
    disabled="#{not facesContext.postback or not facesContext .validationFailed}"/>

It is all inside a confirmDialog

Yes, just let the input ajax-update the button wherein you check in its disabled attribute if the current request is a postback whereby validation is failed.

<p:inputText ...>
    <p:ajax ... update="button" />
</p:inputText>
<p:commandButton id="button" ... disabled="#{not facesContext.postback or not facesContext .validationFailed}" />
