Issue With Declaring Window Object in Extend Script

[Rajan29333875o9cx]

In my .jsx file I have the following function:

function showForm(filePath, dataPath)

{

  alert("Before");

  var dialog = new Window("window", "Select a folder");

  alert("After");

  dialog.show()

}
However, the second alert never appears indicating the code hangs on the Window object declaration.

Any ideas on why this may be?

Just to clarify this is for an extension. This function is called by a JavaScript function that a button calls. I know this showForm function is called because I can see the first alert. Interestingly this works if I run it as a script.

Just running your function in ExtendScript Toolkit, I get a different behavior. I get the first alert, then the tiny window opens briefly (then disappears) and then I get the second alert. Don't know if that's helpful.

Do you get any error messages when running it with the debugger active?

Also, are you sure you run the script with After Effects as host app? Premiere Pro is missing lots of the UI stuff, for example.
