  ICEfaces dataExporter unable to export files
  
  I have a very simple example using an ace:dataTable and ace:dataExporter component, where the ace:dataExporter does not export the table to a downloadable file when clicked. I'm using these components in a Liferay 6.2 + Tomcat 7 JSF portlet environment with ICEfaces 3.3.0 P02.
  The error in my tomcat log: 
  14:10:46,669 ERROR [MissingResourceImpl:78] Resource handler=[com.liferay.faces.
  bridge.application.ResourceHandlerOuterImpl@66e6676f] was unable to create a res
  ource for resourceName=[s4107aa8f-7a4e-4dd3-a2fc-8a18aa77ecb8] libraryName=[null
  ] contentType=[null]

  Relevant part of my view.xhtml:
  <ace:dataExporter id="dataExportExample" fileName="identities" target="identityData" type="csv" />
  <ace:dataTable id="identityData"
                 value="#{simpleTableBean.identities}"
                 var="identity"
                 paginator="true"
                 rows="15">
      <ace:column headerText="id">
          <h:outputText value="#{identity.id}" />
      </ace:column>
      <ace:column headerText="name">
          <h:outputText value="#{identity.name}" />
      </ace:column>
  </ace:dataTable>
  
  A:
  
  The problem was due to missing the dependency liferay-faces-1917-lsv-5-patch version 3.2.4-ga5. It was fixed by adding
  <dependency>
      <groupId>com.liferay.faces.patches</groupId>
      <artifactId>liferay-faces-1917-lsv-5-patch</artifactId>
      <version>3.2.4-ga5</version>
  </dependency>
  
  to my maven pom.xml.
