JSF (PrimeFaces) page doesn't work with single form

I am developing a simple page using PrimeFaces that list informations about some projects. I wanted to add a button that open a dialog with detailed information. The code is quite simple. However it doesn't work:

<h:form id="projectForm">  
  <p:dataTable id="projectDataTable" var="project" value="#{projectMB.projects}" >  
    <p:column sortBy="name" headerText="Name">  
      <h:outputText value="#{project.name}" />  
    </p:column>  
    <p:column sortBy="status" headerText="Status">  
      <h:outputText value="#{project.status}" />  
      <h:outputText value=" (#{project.progress}%)" />  
    </p:column>
    <p:column style="width:4%">  
      <p:commandButton update=":projectForm:display" id="selectButton" oncomplete="PF('projectDialog').show()" icon="ui-icon-search" title="View">  
        <f:setPropertyActionListener value="#{project}" target="#{projectMB.selectedProject}" />  
      </p:commandButton>  
    </p:column>            
  </p:dataTable>  
  <center>
    <p:commandButton id="refreshProjectsButton" actionListener="#{projectMB.refreshProjectList}" icon="ui-icon-refresh" update="projectDataTable"/>
  </center>

  <p:dialog header="Project Detail" widgetVar="projectDialog" resizable="false" id="projectDlg" showEffect="fade" modal="true">  
    <h:panelGrid id="display" columns="2" cellpadding="4" style="margin:0 auto;">  
      <h:outputText value="Name:" />  
      <h:outputText value="#{projectMB.selectedProject.name}" style="font-weight:bold"/>  
      <h:outputText value="Description:" />  
      <h:outputText value="#{projectMB.selectedProject}" style="font-weight:bold"/>  
    </h:panelGrid>  
  </p:dialog>  
</h:form>

I found a solution by adding extra form which enclose dialog:

<h:form id="projectForm">  
  <p:dataTable id="projectDataTable" var="project" value="#{projectMB.projects}" >  
    <p:column sortBy="name" headerText="Name">  
      <h:outputText value="#{project.name}" />  
    </p:column>  
    <p:column sortBy="status" headerText="Status">  
      <h:outputText value="#{project.status}" />  
      <h:outputText value=" (#{project.progress}%)" />  
    </p:column>
    <p:column style="width:4%">  
      <p:commandButton update=":projectForm2:display" id="selectButton" oncomplete="PF('projectDialog').show()" icon="ui-icon-search" title="View">  
        <f:setPropertyActionListener value="#{project}" target="#{projectMB.selectedProject}" />  
      </p:commandButton>  
    </p:column>            
  </p:dataTable>  
  <center>
    <p:commandButton id="refreshProjectsButton" actionListener="#{projectMB.refreshProjectList}" icon="ui-icon-refresh" update="projectDataTable"/>
  </center>

</h:form>  
<h:form id="projectForm2"> 

  <p:dialog header="Project Detail" widgetVar="projectDialog" resizable="false" id="projectDlg" showEffect="fade" modal="true">  
    <h:panelGrid id="display" columns="2" cellpadding="4" style="margin:0 auto;">  
      <h:outputText value="Name:" />  
      <h:outputText value="#{projectMB.selectedProject.name}" style="font-weight:bold"/>  
      <h:outputText value="Description:" />  
      <h:outputText value="#{projectMB.selectedProject}" style="font-weight:bold"/>  
    </h:panelGrid>  
  </p:dialog>  
</h:form>

My question is: why the first code doesn't work - method projectMB.refreshProjectList that refresh the list in java bean is never called. I don't get any errors in javascript and java.

This is a pretty common issue with Dialogs inside forms, and you could easy find an answer if you search a little about this issue.
