I’ve debugged the problem locally and the macro works fine for non-nested spaces. Initially I also got some error (see below) but it was because I didn’t have the xwiki-platform-legacy-oldcore-*.jar JAR in my WEB-INF/lib and this macro requires some legacy APIs. FTR here’s the error I was getting: 2015-10-16 14:06:17,177 [http://localhost:8080/xwiki/bin/get/XWiki/SpaceParentsChildrenService?output...] ERROR o.x.v.i.DefaultVelocityEngine - Left side ($offset) of '<' operation has null value at 94:xwiki:XWiki.SpaceParentsChildrenService[line 14, column 14] 2015-10-16 14:06:17,183 [http://localhost:8080/xwiki/bin/get/XWiki/SpaceParentsChildrenService?output...] WARN o.x.v.i.DefaultVelocityEngine - Deprecated usage of getter [com.xpn.xwiki.api.DeprecatedContext.getLanguage] in 94:xwiki:XWiki.SpaceParentsChildrenService@209,12 2015-10-16 14:06:17,183 [http://localhost:8080/xwiki/bin/get/XWiki/SpaceParentsChildrenService?output...] ERROR o.x.v.i.DefaultVelocityEngine - Left side ($returnedItems) of '<' operation has null value at 94:xwiki:XWiki.SpaceParentsChildrenService[line 252, column 37] I tested with: {{parentschildrenlivetable space="XWiki" order="asc" rowCount="10"/}} Could you confirm that you didn’t have this xwiki-platform-legacy-oldcore-*.jar JAR in your WEB-INF/lib? Also could you let us know if you tried the macro on Nested Spaces? (could you show how you used the macro?). Thanks -Vincent
