CEP panel sending from JSX to HTML

[Jakob Wagner 2048]

Hi

I am making a CEP panel. The panel is part of a multi-panel setup. Multiple panels talk to each other via extendscript.

My problem is that panel A is giving panel B a command. Panel B receives this command and should change the UI. So I need panel B to tell the CEP HTML UI what to do. This will not be triggered by a user action in panel B.

My other communication goes through CSInterface.evalScript with a callback. But I can't use that in this case.

So in other words I need to send a command from JSX to HTML without the user first clicking any UI buttons or anything.

Is there a way to do this?

Thanks,

Jakob

EDIT: This seems to be what I need, but I don't know how to make that work for AE. I get the error "File or folder does not exist."

Ah. It works. Like David writes but without the two back slashes. He writes:

try {
   var xLib = new ExternalObject("lib:\\PlugPlugExternalObject");
} catch (e) {
   alert(e);
}

it should be:

try {
   var xLib = new ExternalObject("lib:PlugPlugExternalObject");
} catch (e) {
   alert(e);
}

Just like the manual says. Sometimes it helps to sleep.

Nice find! Curious, why they have such an error in their code. PS does not seem to fix the issue. I dont get any thing in return when adjusting the code to this
