Hi fellow Liferay'ers,
I'm trying to get the categories of a journalArticle with a Freemarker template.
I tried this code:
<#assign journalArticleId = .vars['reserved-article-id'].data>
<#assign journalArticleResourceLocalServiceUtil = staticUtil["com.liferay.portlet.journal.service.JournalArticleResourceLocalServiceUtil"]>
<#assign assetCategoryLocalServiceUtil = staticUtil["com.liferay.portlet.asset.service.AssetCategoryLocalServiceUtil"]>
<#assign articleResourcePK = journalArticleResourceLocalServiceUtil.getArticleResourcePrimKey(groupId, journalArticleId)/>
<#assign categoryList=assetCategoryLocalServiceUtil.getCategories("com.liferay.portlet.journal.model.JournalArticle",articleResourcePK) >
<#list categoryList as categoryList>
${categoryList.getName()}
</#list>
When i execute the code it throws this error:
08:26:30,582 ERROR [http-nio-8080-exec-10][runtime:60] Error executing FreeMarker template
FreeMarker template error:
The following has evaluated to null or missing:
==> staticUtil [in template "20202#20246#41671" at line 14, column 51]

Tip: If the failing expression is known to be legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing</#if>. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??

Does anyone has an Idea what I am doing wrong here? Thank you in advance.
