Hello guys,I'm trying to create an action that when a document arrive it is duplicated and sent to another folder.But this new folder must be unique with a sequencial number on its name.My only problem is this sequencial number. Anyone knows how to do this?Thanks a lot!

You could count the number of folders already created there and use it as your sequential number:


var sequentialNumber = destFolder.children.length;

Good idea!
Thanks!

But now I got another problem.

When a try to create a new folder with the name of the file that I put into the folder doesnt work…

Here is my script;
//I create a name
var name = document.name+"TestName";
var backupFolder = space.childByNamePath(name); //confirm if the folder with the name exists
if (backupFolder == null && space.hasPermission("CreateChildren"))
{
backupFolder = space.createFolder(name); //Create a folder
}

But nothing happen….

I've tried your code with the Javascript Console and it works for me.

Make sure your space variable points to the path that you want, and check the ${ALFRESCO_HOME}/tomcat/logs/catalina.out file for errors.

Check the "countable" aspect + action, it does exactly what you need.

I don't think the ".children.length" is a good idea. If you create 2 folders it will name them "1" and "2".
Then if you delete folder "1" and try to recreate a new folder, won't it try to name it "2" which already exists?

I personally use the database ID that each node has:


var prefix = "Folder";

var newFolder = companyhome.childByNamePath("my/Path").createNode(null, "cm:folder");
var unique = "_" + newFolder.properties["sys:node-dbid"];

newFolder.properties.name = prefix + unique;
newFolder.save();
