I have a business requirement to alter the generated NodeAliasPath in the following way:
A: Increase the NodeAliasPath to use an 80 character home made version based on the title (ie Ignore the nodeAlias column)

I have managed to get to the point that once the user clicks 'update' the nodeAliasPath reflects the correct way. However on intiial item create/insert the default value is being created.

Something/Somewhere in the save method the value I am sending to the nodeAliasPath is getting overwritten by the system.

I have tried

DocumentEvents.Insert.After += Document_Insert_After;
DocumentEvents.Update.After += Document_Update_After;
DocumentEvents.Insert.Before += Insert_Before;

 private void Document_Update_After(object sender, DocumentEventArgs e)
        {
    TreeNode node = e.Node;
         CreateCustomAliaspath(node);
         node.update();
        }

On inital save/item creation, I can see the documentAlias go from the correct one the system generated one.

So.. nutshell. When I create a new contentItem the saved value is using a system generated value. When I resave or edit the document the home made value is present.
Where do I ensure that on save my custom value is inserted into the database vs the system one.
