Add configuration option to block deletion of non-empty folders

[jpotts]

If you set an expiration date on a folder, the action will delete it when it expires, even if the folder contains children. This is how the add-on was designed, but there may be use cases where that is not preferred. Maybe we need a configuration option, either on a global basis or a folder-by-folder basis (a new property on the expirable aspect) that will only allow the delete if the folder is empty.

Hi Jeff, I hope you are well. I recommended your development and download the two amps you give in the Git. Install them very well, create a business rule and I get your option, BUT, do not find the option in the folder to add the expiration date. My alfresco is 5.1 201606 community. I hope you can help me and I thank you for sharing this development YOURS. Thank you very much.

@martins07 Your comment does not seem relevant to this issue, but I will try to help you. If you use this code as-is, the expiration date is not editable. It will also not show up when the form is in edit mode. It only shows up in view mode. The expiration date property is meant to be set using a rule. If you have added the cxme:expirable aspect to a document or to a folder, you should see a property that displays whatever you set in the cxme:expirationDate property. If you would like that property to be editable, change the Share config in this file.

If you have further questions or comments please create a new issue.
