Setting in liferay-portal-6.2-ce-ga2/tomcat-7.0.42/webapps/ROOT/WEB-INF/classes/portal-ext.properties:
journal.structure.force.autogenerate.id=false
journal.template.force.autogenerate.id=false
used to enable YOU editing structure and template id.
This DOES NOT work anymore in liferay 6.2
Using liferay 5.x (and I've read on the web about liferay 6.1) was fine.
Does anybody know how to do this again?
It seems that there is a fix implemented for this in Liferay 6.2 EE. I am experiencing the same problem on Liferay 6.2 CE though. Hopefully I will be able to solve it.
The fix is discussed in the following Liferay Issue: https://issues.liferay.com/browse/LPS-48441. You can follow it as a possible direction to get the solution.
Regards.
EDIT: If you want to "avoid the patching" of this issue, you could use the Scripting Console from the Control Panel and change the structures or templates ids running a script. You can get it from my response in the Liferay thread in here:
