Browser Widget execute() Acrobat Reader 7 - exception thrown [message #458425]

Hi, group.

I am using the browser widget to display an Adobe Acrobat (pdf) file. I have
a print button on the screen and have the following code in the listener

printButton.addSelectionListener(new SelectionAdapter() {

public void widgetSelected(SelectionEvent e) {
browser.execute("window.print()");
}

});

The idea is to print a pdf document displayed in the browser when you click
the print button.

The above code works fine when I use acrobat reader 5, but throws a
NullPointer exception at line 810 of Browser class when I use acrobat reader
7.

Upon debugging, I realized that for some reason it cannot get the
"parentWindow" property and therefore throws a NullPointer exception.

Any ideas before I "bug" it?

Thanx,
- Kalman

You should definitely post a bug about this. SWT should not be
throwing NPEs.
