Im trying to use notification subscriber to create an extra module property to be used on the edit and frontend, but it doesn't seem to register it
[Subscribe(Standard.Paragraph.Saved)]
    public class SaveSubscriber : NotificationSubscriber
    {
        public override void OnNotify(string notification, NotificationArgs args)
        {

            if (args == null || !(args is Standard.Paragraph.ParagraphNotificationArgs))
            {
                return;
            }

            var pArgs = (Standard.Paragraph.ParagraphNotificationArgs)args;
            if (pArgs.Target.ModuleSystemName.ToLower().Equals("DWCMSModule"))
            {
                pArgs.Target.ModuleProperties.set_Value("test", "1234");
            }
            base.OnNotify(notification, args);
        }


    }
i do hope someone can see where im at fault.

Think there is a little glitch in the API:

So you have to do this - and save the paragraph again since .Saved notification is raised after the paragraph is saved to database.
pArgs.Target.ModuleProperties.set_Value("test", "1234");
pArgs.Target.ModuleSettings = pArgs.Target.ModuleProperties.toString();
pArgs.Target.Save();
And you do not need the base.OnNotify line.

            }
            var pArgs = (Standard.Paragraph.ParagraphNotificationArgs)args;
            if (pArgs.Target.ModuleSystemName.ToLower().Equals("DWCMSModule"))
            {
                pArgs.Target.ModuleProperties.set_Value("test", "1234");
                pArgs.Target.ModuleSettings = pArgs.Target.ModuleProperties.ToString();
                pArgs.Target.Save(); 
            }
        }

    }
Now it looks like this but it still doesn't seem to work.

Just to make sure - you are using the DW 7 interface - the one with the blue ribbon?

Maybe this line could be the problem...

if (pArgs.Target.ModuleSystemName.ToLower().Equals("DWCMSModule"))

Lower case or not?

The problem is the getter on paragraph.moduleproperties...

So do like this:
Dim theProperties As Properties = Me.ModuleProperties
theProperties.Value("test") = "1234"
Me.ModuleSettings = theProperties.ToString()

It seems that the makes it run in an infinite loop so i have to make some tests to see if the value have been changed and only save when that is the case.

pArgs.Target.Save();

 

 

Thank you both for the help.

To prevent the infinite loop, you can add a few lines to the beginning of your OnNotify...

if (HttpContext.Current.Items.Contains(notification)) return;
HttpContext.Current.Items.Add(notification, true);
