Setting a track's output in the Logic Pro's Mixer. - Could not click popup menu item.

Summary

Hi Christian. In an attempt to set the output of a logic track in the mixer, SoundFlow finds the Menu Item information but is unable to instantiate the audio track's output path.

*This is in reference to @Alex_Oldroyd8's thread Fetching path from popup menu #post-3 *

Steps to Reproduce:

Create a script with the following function;

function setOutputPath({ menuPath }) {
    //Logic Pro
    const logic = sf.ui.app("com.apple.logic10");

    //Activate Logic's main window
    logic.appActivateMainWindow();

    //Mixer Groups
    const mixerGroup = sf.ui.app("com.apple.logic10").mainWindow.groups.whoseDescription.is("Mixer").first;

    //Mixer Layout
    const mixerLayout = mixerGroup.children.whoseRole.is("AXLayoutArea").whoseDescription.is("Mixer").first;

    //First Selected Track
    const firstSelectedTrack = mixerLayout.getElements('AXSelectedChildren').first;

    //First Selected Track's Buttons
    const channelStripButtons = firstSelectedTrack.buttons;

    //Get Channel Strip Button Info
    const channelStripButtonInfo = channelStripButtons.map(btn => ({
        title: btn.getString("AXDescription"),
        buttonType: btn.getString("AXRoleDescription"),
        frame: {
            h: btn.frame.h,
            w: btn.frame.w,
        },
        element: btn,
    }));

    //Output Button (First Button that matches {height: 18 width: 58})
    const outputButton = channelStripButtonInfo.find(btn => btn.frame.h === 18 && btn.frame.w === 58).element

    //Log Matching Popup Menu Item from menuPath arg
    log(outputButton.popupMenuFetchAllItems().menuItems.filter(mi => JSON.stringify(mi.path) === JSON.stringify(menuPath))[0]);

    //Close Popup
    logic.appActivateMainWindow();

    //Wait for demonstration purposes only.
    sf.wait()

    //Attempt to set the tracks output
    outputButton.popupMenuSelect({
        menuPath,
    });
}

Set up a Logic session as follows;

• Create a new blank Logic Session
• Select Menu Item "View" => "Show Mixer"
• Create an audio track "Audio 1"
• Select the "Audio 1" track in the Mixer

Test 1
Call the function with the following call;

setOutputPath({
    menuPath: ["Bus", "Bus 1"],
});

This attempt is successful at finding the filtered menu item and setting the output

With the "Audio 1" track selected in the mixer;

• Select Menu Item "Track" => "Create Track Stack…"
• Select the "Summing Stack" Radio button.
• Click the "Create" button.
• Re-select the "Audio 1" track only.
• Set Output of "Audio 1" to "No Output".

Test 2
Call the function with the following call;

setOutputPath({
    menuPath: ["Bus", "Aux 1", "Bus 1 → Aux 1"], 
});

This attempt is successful at finding the filtered menu item but failed to set the output.

This is what the log report looks like;

Expected Results
The "Audio 1" tracks output should be set to the following path;

[
        "Bus",
        "Aux 1",
        "Bus 1 → Aux 1"
    ],

As seen in the following screen-shot the path exists

Actual results
The attempt is successful at finding the filtered menu item, but failed to set the output (ie "Could not click popup menu item").

Let me know if you have any further questions. :-)

Rock on!
