Unique name

The script generates unique document name based in metadata values each time new document is uploaded.

Description:

• Property okp:data.id store unique autoincremental value.
• Property okp:data.project.code store project code value.
• Property okp:data.customer store customer code.
• Property okp:data.description store document description.
• When a new document is uploaded user must fill all fields except okp:data.id which is automatically set by OpenKM.
• When PropertyGroup is changed - event fired - is executed automatic code which generates okp:data.id and rename document based on projectCode-autonumericId-clientCode-description.documentExtension.
