Yes, I think Screen Wizard plugin will do what you are looking for. I actually wrote a layer on top of it that allows me to have experience closer to dynamic scaffolding (i.e. specify a few properties that I want to display, and it automatically does it for me). Here is how it works. Suppose you have a domain object Bill class Bill { LocalDate endDate float daysBilled //this may be useful for smaller increments than day double cost double amount } To create the CRUD screen, just create a controller that subclasses AbstractEditScreenController (a class I wrote). The class defines screenArea Parameters (what you call configurationItems) that need to be used to construct the screen. As you can see, screenAreaBillParams below defines the property name to be displayed, which template is needed to render it (it actually needs three templates, one for edit page, and two for list page - I am sure you can adopt it for your own layouts). class ScreenBillController extends AbstractEditScreenController { static def screenAreaBillParams = [ [displayName: "End Date", propertyName: "endDate", templateName: "localDate", listHeaderTemplateName: "listHeader", listItemTemplateName: "listItem"] , [displayName: "Days Billed", propertyName: "daysBilled", templateName: "default", listHeaderTemplateName: "listHeader", listItemTemplateName: "listItem"] , [displayName: "Disable", propertyName: "disable", templateName: "checkItem", listHeaderTemplateName: "listHeader", listItemTemplateName: "listItem"] , [displayName: "Amount", propertyName: "cost", templateName: "default", listHeaderTemplateName: "listHeader", listItemTemplateName: "listItem"] ] def fillInFilteredProperties(def domainObject) { log.info "Filling in Filtered Properties while Saving Object, setting Bill Properties" domainObject.site = BaseController.currentSite(session) domainObject.utilityAccount = BaseController.currentUA(session) } String getCurrentDOName () { "Bill" } String getDisplayDOName() { "My Bill" } def getThisClass() { Bill.class } List getScreenAreaDefinitions() { screenAreaBillParams } } The result is a nice CRUD screen (attaching the screenshot for a very similar GasBill from the app I am working on). I am going to send you the modified plugin code privately. If anybody else is interested, let me know.

I think the plugin you are mentioning might solve the problem. Right now, scaffolding is generated off static classes, which basically are the table structure. I need the scaffolding structure to be based off the table data, not just the structure. For example, one of my users adds a row to ConfigurationItem table. Then, in the corresponding ConfigurationWorksheet view, there is now another item that can be CRUD-ed. Does that make sense? Basically, I could hardcode a class that includes all the configurationItems, and do an auto scaffold on it. However, that limits my system to only working with the current configurationItems, and would allow for zero-expandability without having to re-code. I'm trying to set it up so the user can add items without my having to recode. Thanks for your help. -Mo Jean Barmash wrote: > > Mo, > > I am not sure I completely understand what you are trying to do, perhaps > you can provide a more concrete example.
