Preconditions with parameter do not work

I have tried to make a sql precondition with a parameter


 

           select count(*) from  

        ( SELECT sum(bytes)/1024/1024 free 

          FROM USER_FREE_SPACE

          WHERE TABLESPACE_NAME=’"${tablespace_data}"’ )

    WHERE free > "${tablespace_data_freespace}                             

     

     


I this feature planned for the future ??

I guess I missed including that in the parsing. I created  http://liquibase.jira.com/browse/CORE-1070 to track it.
