"onProjectChanged" event

[ilya_ananyev]

Hello guys,

I've noticed in the last commit of GitHub - Adobe-CEP/Samples: Code samples for CEP extensions new event called "onProjectChanged" with a commented out line at Samples/Premiere.jsx at master · Adobe-CEP/Samples · GitHub​ . I've decided to test this new (?) functionality (I'm using Adobe Premiere Pro CC Version 12.1.1) and removed the slashes. I've expected, that this event will be triggered by any kind of project manipulation, however it wasn't triggered at all: I've tried changing sequences, adding another video to the project, renaming sequences etc. Is there anything I'm doing or understanding wrong?

Regards

Ilya

Try having just one project open; do the changes get registered now?

[ilya_ananyev]

No. There is currently only one project open. The function registerProjectChangedFxn being called as expected at the panel load, but myOnProjectChanged function is not getting triggered.

Does PProPanel successfully respond to onProjectChanged events? [Open PPro's Events panel, to confirm.]

I'm not sure if I understood you right, following has been done: opened window -> events. Everything, what I see are some invalid fonts warnings and "<number> items selected: <sequence name>" information logs. Here is myOnProjectChanged function:

myOnProjectChanged : function(documentID){

   var msg = 'Project with ID ' + documentID + ' Changed.';
   // Commented out, as this happens a LOT.
   $._PPP_.updateEventPanel(msg);
   app.setSDKEventMessage(msg, 'info');
   alert("project changed");
},

If I uncomment the updateEventPanel() line in PProPanel, the message is posted correctly.

Ok, let's inspect why I don't have the same behavior.

Which particular action should be done to trigger onProjectChanged event? (I've tried creating sequence, changing length of video in sequence, placing new video in sequence, creation of new project etc.) Which version and platform do you use to perform the test? (I've tested with Version 12.1.1 and 12.1.0 under Mac).

Is there any documentation to the events we can listen for at all?

Where does your implementation depart from PProPanel's working implementation?

I have no idea why you'd want to create a sequence every time the project's contents change.

No, there is no documentation yet; we provide working code first.

I have no idea why you'd want to create a sequence every time the project's contents change.

I've created a sequence to trigger the "onProjectChanged" event. As I've already mentioned, I've tried also following actions to trigger the event:

creating sequence, changing length of video in sequence, placing new video in sequence, creation of new project etc.

So, once more, should any of these actions trigger onProjectChanged? If so, please let me know if you are using any other version of Adobe Premiere than me. (I've tested with Version 12.1.1 and 12.1.0 under Mac)

Here are the differences to the current master version of PLremiere.jsx file (this is the only file I changed). Notice: I'm calling "loaded" alert in registerProjectChangedFxn, this alert works as expected.

Yes; see screen video of PProPanel.

More specifics on what does and does not constitute a project change:

New sequence: yes

Change length of sequence: no

Add anything to project: yes

New project: no

So, those specifics aside; what workflows are you trying to support?

[ilya_ananyev]

As far as I see, following functions were triggered: "onItemAddedToProject", "projectPanelSelectionChanged". So "onProjectChanged" has never been called by you neither, otherwise (if you removed slashes at line 1667 in Premiere.jsx) we would see 'Project with ID <documentID> Changed'.

What I am trying to do is to detect, if another sequence was selected ( = active sequence is changed), the sequence has been renamed or the structure of sequence has been changed. I was hoping, that "onProjectChanged" event is triggered by Premiere itself, to make it possible to act somehow to the project changes. Otherwise I don't understand including functions myOnProjectChanged and registerProjectChangedFxn to the samples - myOnProjectChanged is never called.
