Hi Marcin,



Business process can communicate with the client side via Websockets. You can send a Websocket message to the page with the name of the tab that you want to open.



Here are the steps to follow:

1. Add usings in your business process https://prnt.sc/q6gknw:

Terrasoft.Configuration

Terrasoft.Messaging.Common

Newtonsoft.Json

2. Create a method under Methods tab:

 

public static void SendTabName(UserConnection userConnection, Guid recordId, string tabName) {
	string senderName = "TabSender";
	string message = JsonConvert.SerializeObject(new {
	    RecordId = recordId, 
	    TabName = tabName
	});
 
	MsgChannelUtilities.PostMessage(userConnection, senderName, message);
}

3. Add process parameters RecordId and PageTabName.

4. Add a script task that invokes a method with message:

 

SendTabName(Get<UserConnection>("UserConnection"), Get<Guid>("RecordId"), Get<string>("PageTabName"));
return true;

5. Subscribe for the message on the page:

define("MyPage", [],
function() {
	return {
		entitySchemaName: "MyObject",
		methods: {
			init: function() {
				this.callParent(arguments);
				this.Terrasoft.ServerChannel.on(Terrasoft.EventName.ON_MESSAGE, this.onTabMessageReceived, this);
			},
			destroy: function() {
				this.Terrasoft.ServerChannel.un(Terrasoft.EventName.ON_MESSAGE, this.onTabMessageReceived, this);
				this.callParent(arguments);
			},
			onTabMessageReceived: function(sender, message) {
				if (message && message.Header && message.Header.Sender === "TabSender") {
					var result = this.Ext.decode(message.Body);
					if (this.get("Id") === result.RecordId) {
						this.glbSetActiveTab(result.TabName);
					}
				}
			},
			glbSetActiveTab: function(tabName) {
				this.set("ActiveTabName", tabName);
			}
		}
	};
});

Dmytro Smishchenko,

Thank You for complete clarification. Its works.

Not exactly fit to my case but was useful to take forward my implementation and fix problem.

In my solution, process runs "Pre-configured page" task, so "Script task" runs  after this steps sends message but before load "Project edit page" back then i can't handle this message.

My final solution is setting sessionStorage variable on "Pre-configured page" init method and read and destroy this variable on "Project Page 2 edit" initTab method like this ..

	methods: {
			initTabs: function() {
				//this.callParent(arguments);
				if(sessionStorage.getItem("SetStructureTab"))
				{
					this.set("ActiveTabName", "StructureTab");
					this.set("StructureTab", true);
					sessionStorage.removeItem("SetStructureTab");
				}
				else{
					this.callParent(arguments);
				}

Regards,
