Need Help Creating QC release with Groovy

Hi all,

I am not able to create a release in QC with Groovy

I have created a release folder, but get errors when I try to add a release to that folder.  All examples that I have seen are VB which is listed below:  Groovy will not allow me to pass 'null' when adding an item.

// Creates the release Folder

Set oReleaseFolderFactory = tdc.ReleaseFolderFactory
Set rootReleaseFolder = oReleaseFolderFactory.Root
Set oReleaseFolderFactory = rootReleaseFolder.ReleaseFolderFactory
Set relFolder = oReleaseFolderFactory.AddItem(Null)
relFolder.Name = "Release Folder 1"
relFolder.Post

// Creates the Release

Set relFac = relFolder.ReleaseFactory
Set rel = relFac.AddItem(Null)
rel.Name = "Release 1"
rel.StartDate = DateTime.Now
rel.EndDate = DateTime.Now + 90
rel.Post

The work around for Adding a folder is by passing the parent folder ID along with the name, but I am still unable to figure out a way to create a release.  My code is below and the folderID is the Parent ID of the Folder that I want to place the release in.  According to QC's OTA documentation, I should be able to pass Null(which doesnt work with groovy) or Parent folderID.

I keep getting the error, 'Description: Failed to Post Simple Key Entity'

// MY - Create the release

relFactory = folder.ReleaseFactory
release = relFactory.AddItem(folderID)
release.Name = "Sprint 51"
release.StartDate = DateTime.Now
release.EndDate = DateTime.Now + 90
release.Post()
