Issue

  • When deploying layout templates with Freemarker code e.g. like the below:

    <span>${languageUtil.get(locale, "read-more")}</span>

    <span>${sessionClicks.get(request, "test", "My Test")}</span>

    A stacktrace will appear in the server logs:

Environment

  • Liferay DXP 7.0+

Resolution

  • The error is being thrown as the custom template is trying to utilize the variable while it's null.

    One simple way to resolve this would be to account for such case, e.g.:
    <#if request??>
        <#assign myVar = sessionClicks.get(request, "test", "My Test") />
    <#else>
     <#assign myVar = "" />
    </#if>

    <div class="my-liferay-layout" id="main-content" role="main">
     <div class="portlet-layout row">
     <div class="col-md-12 portlet-column portlet-column-only" id="column-1">
     ${processor.processColumn("column-1", "portlet-column-content portlet-column-content-only")}
     </div>
     <span>${myVar}</span>
     </div>
    </div>
