Hello people!

I'm upgrading a portlet with xhtml files instead of jsp files from 6.2 to 7.2 liferay version. Requirements are that migrated portlet continues to work with xhtml files. I have already updated com.liferay.faces dependencies, particularly liferay-faces-bridge-impl to com.liferay.faces.bridge.impl.

Now in a xhtml file there is the <portlet:defineObjects /> tag.

This tag, I saw into com.liferay.faces.bridge.impl.jar's portlet.taglib.xml, is no longer present. In fact when I deploy the portlet I get this error: "Tag library supports namespace http://java.sun.com/portlet_2_0 but no tag was defined for name defineObjects". How can I solve this issue? Is it safe to remove <porlet:defineObjects/> with no other edit?

For completeness this is the dependency into pom.xml

<dependency>
    <groupId>com.liferay.faces</groupId>
    <artifactId>com.liferay.faces.bridge.impl</artifactId>
    <scope>runtime</scope>
</dependency>

And this is the snippet of the involved xhtml file

<?xml version="1.0" encoding="UTF-8"?>
<f:view
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:f="http://xmlns.jcp.org/jsf/core"

    xmlns:bridge="http://liferay.com/faces/bridge">

    <h:head />

    <portlet:defineObjects/>
    <f:event listener="#{bean1.onPageRender}" type="preRenderView" />

    <h:body>
      <alloy:row>
        <alloy:column>
          <h:form>
            <p:messages autoUpdate="true" />
            <alloy:fieldset>
              <alloy:row>
                <alloy:column>
                  <alloy:field label="visible">
                    <p:inputTextarea value="#{bean2.visible}" />
                  </alloy:field>
                </alloy:column>
              </alloy:row>
            </alloy:fieldset>

            <p:commandButton action="#{bean1.submit}" value="Save" />
          </h:form>
        </alloy:column>
      </alloy:row>
    </h:body>
</f:view>

Thank you.
