Hello Every one, I developed a simple api that return the Nodes names under the Root node; i implemented this using SignalR and subscribed to the Saveandpublish event , when i click on the save and publish button i call my show() function inside of the CustomHub Class every thing is working fine. the only problem is when i click on save and publish for only one time no thing happen!? but when i click twice its changes :O ! the ajax Request is called on both scenarios, and the response on the first case returns the old value on the other hand the second case returns the new value. any ideas
