trigger form validation from button in another form

I'm using Primefaces with JSF-2 on Glassfish, trying to cross validate a form. Here's the scenario:

<h:form id="form1">
    <p:messages id="msgs" showDetail="false" autoUpdate="true" closable="true" />
    some input fields with validation
</h:form>

<h:form id="form_upload">
    some upload fields that dont trigger validations
</h:form>

<h:form id="buts">
    <p:commandButton id="save" value="Save" action="#{bean.save}"
        update=":form1 :form1:msgs" process=":form1">
</h:form>

I would like button save to trigger validations on form1, is that possible?

You can use PrimeFaces' <p:remoteCommand>

<h:form id="form1">        
    some input fields with validation
    <p:remoteCommand name="rc" update="@form" action="#{bean.save}" />
</h:form>

sample remote call:

<h:form id="buts">
   <p:commandButton value="Save" type="button" onclick="rc()" />
</h>

Use the attribute process and specify each components you want to be processed on the server:

<p:commandButton id="save" value="Save" action="#{bean.save}"
     process=":form1 :form_upload" update=":form1" />

Don't forget to put a p:messages somewhere in :form1, else you want to update it too.
