I worked Application Display Templates on liferay 6.2, I use freemarker help pagination the dynamics data list of liferay. When I upgrade to liferay 7, it is a problem. Liferay 7 use code <#assign records = ddlDisplayTemplateHelper.getRecords(reserved_record_set_id)> for get a records.
Old code:
<#assign DDLRecordLocalService = serviceLocator.findService("com.liferay.portlet.dynamicdatalists.service.DDLRecordLocalService")>
<#assign records = DDLRecordLocalService.getRecords(reserved_record_set_id)>
<#assign totalRecord = DDLRecordLocalService.getRecordsCount(reserved_record_set_id, 0) >
It doesn't work.
So I try <#assign serviceLocator = staticUtil["com.liferay.portal.template.ServiceLocator"]> but staticUtil get an error.
The following has evaluated to null or missing:
==> staticUtil [in template "20115#20159#21387" at line 9, column 27]
Tip: If the failing expression is known to be legally refer to something that's sometimes null or missing
In portal-ext.properties I have added:
freemarker.engine.restricted.classes=
freemarker.engine.restricted.packages=
freemarker.engine.restricted.variables=
The properties you refer to have been moved to an OSGI config in Liferay 7/DXP.
To deploy them you need to create a file named com.liferay.portal.template.freemarker.configuration.FreeMarkerEngineConfiguration.cfg and place it under $LIFERAY_HOME/osgi/configs
The content of the file will be the following:
restrictedVariables=
To find all the configs and their defaults you can have a look at the class com.liferay.portal.template.freemarker.configuration.FreeMarkerEngineConfiguration
That you can find in the Liferay source code.
I think those properties in portal-ext.properties are just ignored in liferay 7.
You can admin those properties in Control Panel → Configuration → System Settings → Foundation → FreeMarker Engine and remove "staticUtil" (or remove "serviceLocator" directly) from restricted variables. (liferay reboot is required)
Go to Control Panel -> System Settings -> Foundation Page
Find FreeMarker Engine from list click on it .
Remove serviceLocator variable and staticUtil from restricted variables by Clicking on (-) icon.
If you want to use staticUtil object then also remove this variable from restricted variables.
Save it.
Restart Liferay server.
You will direct access to serviceLocator object in your Application Display Template.
In liferay 7.1. you will find Freemaker Engine under
Control Panel -> System Settings -> Platform -> Template Engines
In liferay-ce-portal-7.1.1.2-ga3 version, the file is renamed to
com.liferay.portal.template.freemarker.configuration.FreeMarkerEngineConfiguration.config
