[opencms-dev] How can I re-initialize the contents of a formatter into a specific language?

[Georg Westenberger]

Hello Patric,

This is actually supported by the formatter tag. Unfortunately, we 
forgot to configure it in the TLD file, but you can easily do so:

- Open the WEB-INF/opencms.tld file in your OpenCms installation
- Find the entry for the formatter tag, which looks like this:
    <tag>
        <description>
            This tag loads single XML content items for ADE formatters.
        </description>
        <name>formatter</name>
        <tag-class>org.opencms.jsp.CmsJspTagFormatter</tag-class>
        <body-content>JSP</body-content>
        <attribute>
            <name>var</name>
            <required>true</required>
            <rtexprvalue>true</rtexprvalue>           
        </attribute>
        <attribute>
            <name>val</name>
            <required>false</required>
            <rtexprvalue>true</rtexprvalue>           
        </attribute>     
    </tag>  

- Add a new "locale" attribute to this entry as follows:

 <tag>
        <description>
            This tag loads single XML content items for ADE formatters.
        </description>
        <name>formatter</name>
        <tag-class>org.opencms.jsp.CmsJspTagFormatter</tag-class>
        <body-content>JSP</body-content>
        <attribute>
            <name>var</name>
            <required>true</required>
            <rtexprvalue>true</rtexprvalue>           
        </attribute>
        <attribute>
            <name>val</name>
            <required>false</required>
            <rtexprvalue>true</rtexprvalue>           
        </attribute>
        <attribute>
          <!-- Add this new attribute! -->
          <name>locale</name>
          <required>false</required>
          <rtexprvalue>true</rtexprvalue>
        </attribute>
    </tag>  

- Restart your servlet container.

- Now you can use this attribute in your formatter as follows:


<cms:formatter var="content" val="value">
       <c:if test="${empty content.localeNames[cms.locale]}">
           <cms:formatter var="content" val="value" locale="en" />
       </c:if>

Kind Regards,
Georg.
