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>
I also added This lines to the portal-setup-wizzard.properties
freemarker.engine.restricted.classes=
freemarker.engine.restricted.variables=
freemarker.engine.restricted.packages=
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.
in liferay 7 they have change the setting of freemarker engine now the configurazion is in the control panel
Control Panel -> Configuration -> System Settings
-> Foundation -> FreeMarker Engine -> Restricted Variables
you have to remove here the restrict varibles
The package of object are changed in liferay 7 so the correcti freemarker in this case is
<#assign journalArticleId = .vars['reserved-article-id'].data>
<#assign journalArticleResourceLocalServiceUtil = staticUtil["com.liferay.journal.service.JournalArticleResourceLocalServiceUtil"]>
<#assign assetCategoryLocalServiceUtil = staticUtil["com.liferay.asset.kernel.service.AssetCategoryLocalServiceUtil"]>
<#assign articleResourcePK = journalArticleResourceLocalServiceUtil.getArticleResourcePrimKey(groupId, journalArticleId)/>
<#assign categoryList=assetCategoryLocalServiceUtil.getCategories("com.liferay.journal.model.JournalArticle",articleResourcePK) >
<#list categoryList as categoryList>
${categoryList.getName()}
</#list>
