hi everybody, i’m trying to open a pdf file in Java Swing SWT Browser. I can open the pdf, and closing it, and open the same or different pdfs without any error.
But when I rewritten the pdf, (same url, different content) i get “Widget is disposed” error. It does not create a new browser.
How can i open the rewritten pdfs with swt browser?

What I have tried:

I tried create the shell and display after disposed but did not work.
Also Display.getDefault.asyncExec did not work.
