Tilman Hausherr commented on PDFBOX-2849:
-----------------------------------------
I'll leave that to you... btw, I found this in PDTerminalField:
{code}
protected final void applyChange() throws IOException
{
if (!acroForm.getNeedAppearances())
{
constructAppearances();
}
// if we supported JavaScript we would raise a field changed event here
}
{code}
Is this correct or is the "!" wrong?
