InDesign script closed immediately.

Hello everyone!

I’m trying to create a small plugin to manage my product listings.

It’s a user interface that contains the information needed to automatically fill out my document.

The plugin uses named objects such as “Model Name”

and automatically fills in the fields with data from a CSV file.

Previously, I had written a windowed version to test and debug it. But I needed a palette/dialog box to scroll through the entire document while I enter the information (which doesn’t work with a windowed version because the document remains static).

And I wanted an OK/Apply button to confirm changes and continue working without the page closing, while still being able to navigate the document at the same time.

For now, the problem is at the end of the script with dlg.show();

The dialog box closes instantly when I click on it.

Here is the code.

Can you help me?:)
