Unable to save domain objects until CRUD scaffold is used

I'm having the strangest problem with a controller in a Grails project. I am trying to do a simple update of a domain object. Here is a simplified version of the controller

def updateRecord = {
    def foundHVT = Process.get(params.hvt)

    foundHVT.summaryBy = params.summaryBy
    foundHVT.catalogBy = params.catalogBy
    foundHVT.editBy = params.editBy
    foundHVT.produceBy = params.produceBy
    foundHVT.correctedBy = params.correctedBy
    // a bunch more of these

    foundHVT.save(flush: true);

    redirect (action:resource, id: params.hvt)
}

If I run the a new instance of the application of and use this controller to update an object, it doesn't work, the object doesn't save. It will look fine within the controller. I can, for example, 开发者_JAVA百科re-query the object and the changes are there, post save.

Now here's where it gets weird. If i use the preset scaffold edit controller and update/save an domain object -- and then switch back to this "updateRecord" controller it works FINE until i shut down the server it is working on?!?

I realize I am missing something very basic, but I can't find what it is. Any guidance would be most graciously appreciated.

As HVGOTCODES noted Grails Clean seems to have fixed whatever weirdness was going on with this controller.

try putting a "def scaffold=true" in your controller if it does not already have the normal entry points.

Probably scaffolding save fills some field that you don't.

Possible problems:

1. Do check save() result and render foundHVT.errors the way Grails does. Add failOnError: true parameter to save() or just check foundHVT.hasErrors(). Look at foundHVT.errors.allErrors for validation problems.

2. Why not foundHVT.properties = params?

3. What is there is no foundHVT?
