I have created a smart object which retreives a list from sharepoint. I added a parameter to a method which uses the getlist method of the sharepoint service. However, I couldn't find any way to map the parameter to a particular field. In other words, the input properties screen doesn't appear if  I use the GetList method. It only appears with the Load method. However, the Load method adds an ID column of its own which doesn't exist in the list. Has anyone tried retreiving a particular item from a sharepoint list by passing parameters. Any help would be greatly appreciated.
