Hi,

I'm building a two-way communication bridge between a Perspective view and an embedded HTML page (via the Iframe component), using the WebDev module :

Perspective View --\> HTML Page : OK

HTML Page --\> Perspective View : NOPE

WebDev Python resource (`doPost`) receives the POST, decodes the JSON body, and calls `system.perspective.sendMessage()` with an explicit `sessionId` passed from the client.  
Message Handler is set up on the view, scope `session`, listening for the matching message type, and does `self.view.custom.config = payload['data']`.

Is there any solution for that ?

Webdev does not have access to the currently active perspective session's context.

You'll need to change your doPost to send a message targeting the specific project sessions using `system.util.sendMessage`. From there, have a Session message handler configured that filters off the included session id, and re-broadcasts the message and payload to the session at the session level via `system.perspective.sendMessage`
