Dear forum,
I created a TabbedPalette and now want it to add automatically on start up. My first attempt was to add it to the ‘Startup Scripts’ folder, but this, obviously, didn’t work so I reread the documentation more carefully and found out that this should be done using the create document event.
You can add a palette to an existing browser window at any time (as long as the identifier is unique), and
you can use the create document event to add your palette to new browser windows on creation.
(Bridge CS6 scripting reference, page 87)
Here’s a snippet illustrating the problem:
onCreateDocument = function(event) {
if (event.object instanceof Document && event.type == "create") {
$.writeln("Document is created");
CreateTabbedPalette();
return {handled: true};
}
}
app.eventHandlers.push({handler: onCreateDocument});
function CreateTabbedPalette() {
$.writeln("Entering the 'CreateTabbedPalette' function");
$.writeln("App documents length = " + app.documents.length);
$.writeln("Exiting the 'CreateTabbedPalette' function");
}
It seems that the create document event is triggered before the document is actually created so app.documents.length = 0; as a result, later when I try to add a TabbedPalette to the current document -- app.documents[0] – an error occurs.
Am I doing something wrong, or adding a TabbedPalette via menu item is the only option?
Regards,

I tried to use the loaded event — no joy.
Though the palette is added on start up, at the line which adds the TabbedPalette, an error occurs:
So I attempted to enclose the line into a try-catch bloc:
Here's what I get in the console:
Document is created
App documents length = 1
Document: 1280
Bad argument list, line: 58
true
So the active document is valid and I can get its properties: e.g. width)
The palette has been created and is visible in Bridge. However, the error (bad argument) occurs when the script is triggered by the event (when run from ESTK, no error happens) and the variable 'c' is undefined which leads to further errors when the script references it.
Thanks for your suggestion, but this doesn't work. It still produces the 'Bad argument list' error on creation of the TabbedPalette -- even after 'sleeping'.
I also tried to wait till the document becomes available like so:
onCreateDocument = function(event) {
if (event.object instanceof Document && event.type == "create") {
$.writeln("Entering the 'onCreateDocument' function");
while (app.documents.length == 0) {
$.writeln("Let's wait for a sec");
$.sleep(1000);
}
CreateTabbedPalette();
return {handled: true};
}
}
app.eventHandlers.push({handler: onCreateDocument});
function CreateTabbedPalette() {
$.writeln("Entering the 'CreateTabbedPalette' function");
$.writeln("App documents length = " + app.documents.length);
$.writeln("Exiting the 'CreateTabbedPalette' function");
}
But this hangs Bridge.
So far I decided in favour of the 'menu element with check box' approach:
var set = null;
if (MenuElement.find("Adobe Bridge Script")) {
$.writeln("Error:Menu element already exists!\nRestart Bridge to run this script again.");
}
else {
CreateMenuElement();
}
function CreateMenuElement() {
var menuElement = new MenuElement("command", "Adobe Bridge Script", "at the end of Tools", "kasAdobeBridgeScript");
menuElement.canBeChecked = true;
menuElement.onSelect = function() {
var tabbedPalette = GetPalette("AdobeBridgeScript");
if (tabbedPalette == null) {
CreateTabbedPalette();
menuElement.checked = true;
}
else if (tabbedPalette != null && !tabbedPalette.visible) {
tabbedPalette.visible = true;
menuElement.checked = true;
}
else if (tabbedPalette != null && tabbedPalette.visible) {
tabbedPalette.visible = false;
menuElement.checked = false;
}
}
}
function CreateTabbedPalette() {
// Create Tabbed Palette here
}
function GetPalette(id) { // Return either palette if it already exists, or null
var palette,
palettes = app.document.palettes,
result = null;
for (var i = 0; i < palettes.length; i++) {
palette = palettes;
if (palette.id == id) result = palette;
}
return result;
}
