Hello,
I have changed the getPropertyValues return type to XRow. One Problem I'm facing is that the stated UNOtype sequence is not available for me. I checked com.sun.star.uno package also. I typecasted the command.argument to Property[] because from these two examples: http://wiki.openoffice.org/wiki/Documentation/DevGuide/UCB/Executing_Content_Commands http://wiki.openoffice.org/wiki/Documentation/DevGuide/UCB/Executing_Content_Commands Argument is initialized as com.sun.star.beans.Property[](specifying it particularly because there is a Property type in chemistry api also).
