grails delete not persistent

Question

I was trying to delete a more complex related object from my db, so I investigated using grails console and came up with this:

            TextContent textContent = ...The item to delete...

            // TextContent hasMany BundleText
            // BundleText belongsTo BundleVersion
            textContent.bundleTexts.each {
                BundleVersion bundleVersion = it.bundleVersion
                bundleVersion.removeFromBundleTexts(it)
                textContent.removeFromBundleTexts(it)
                it.delete()
                //bundleVersion.save()
            }
            // Language hasMany TextContent
            // Language belongsTo textContent (?)
            textContent.language.removeFromTextContents(textContent)

            // TextContent belongsTo textCode
            TextCode textCode = textContent.textCode
            textCode.removeFromTextContents(textContent)

            textContent.delete()
            //textCode.save()

Now this all works fine in the grails console, so I put it inside my database service, and run the app. The app runs the method succesfully (verified), but when it re-read the collection it comes up again.. Big mystery...!?

Anyone seen anything like it? Or am I just embarassingly naive?

EDIT

For clarification:

class TextCode {
    static hasMany = [ textContents : TextContent ]
}

class TextContent {
    Language language
    static belongsTo = [ textCode : TextCode ]
    static hasMany = [ bundleTexts : BundleText]
}

class BundleText {
  TextContent textContent
  static belongsTo = [ bundleVersion : BundleVersion ]
}

class Language {
    static hasMany = [ textContents : TextContent ]
}

Not sure why the above didn't work, but I managed to solve it by direct HQL instead.

BundleText.executeUpdate("delete BundleText bt where bt.textContent=:content", [content: textContent])
TextContent.executeUpdate("delete TextContent tc where tc.id = :id", [id: textContent.id])
