Show/hide keyframed properties from an extension

I have an extension that executes function test() on a button click, to show/hide properties with keyframes:

function test() {

var res = false;

var msg = 'default';

var comp = _proj.activeItem;

if (!comp || !(comp instanceof CompItem)) {

msg = 'No active item or active item is not a comp';

return toJSON(res, msg);

}

var layer = comp.layer(1);

if (!layer) {

msg = 'No layer selected';

return toJSON(res, msg);

}

layer.selected = true;

var cmdStr = 'Reveal Properties with Keyframes';

var cmdId = executeCommand(cmdStr);

if (cmdId == 0) {

msg = 'Command \'' + cmdStr + '\' id not found';

return toJSON(res, msg);

}

msg = 'Executed \'' + cmdStr + '\' (' + cmdId + ')';

layer.selected = false;

return toJSON(res, msg);

}


function executeCommand(cmdStr) {

var cmdId = 0;

cmdId = app.findMenuCommandId(cmdStr);

if (cmdId == 0) return cmdId;

app.executeCommand(cmdId);

return cmdId;

}

When I call test() the first time, it works and opens keyframed props, but when I call it again, it opens all props of the layer. On the other hand, if after the first call I click away from the extension window and focus AE UI, it works and hides keyframed props.

Does anyone here have any experience re this behavior?
