Hello!
I am working on a plug-in that controls a running slideshow with the
XPresentation2 interface. The problem I am having is that
occasionally, when I call end() on it, OO freezes -- never returning
from JNI_proxy.dispatch_call(). Initially I thought this might be due
to not calling the API from the correct thread, so I updated the code
to run on an XRequestCallback to ensure that I am executing end() on
the UNO main thread. My code is that calls end() is as follows:
=============================================================
private void ClosePresentationWindow()
{
if ( !m_session.IsFullscreenWindowDisposed() )
{
m_session.SetFullscreenWindowDisposed( true );
// Run from OO UI thread
DesktopTools.RequestAnonymousCallback( new XCallback()
{
@Override
public void notify( Object arg0 )
{
m_session.GetPresentation().end(); // HANG (sometimes)
}
} );
}
}
=============================================================
And RequestAnonymousCallback() looks like this:
=============================================================
public static boolean RequestAnonymousCallback( XCallback callback )
{
XContextWrapper xCtxWrapper = GetContext();
if ( !xCtxWrapper.IsValid() )
return false;
try
{
XRequestCallback xRequestCallback = AsyncCallback.create(
xCtxWrapper
.GetContext() );
if ( xRequestCallback != null )
{
xRequestCallback.addCallback( callback, null );
return true;
}
}
catch ( RuntimeException e )
{
// do nothing
}
return false;
}
=============================================================
Unfortunately, this does not seem to fix the problem, and so I am left
with OO crashing hard on an unpredictable basis. Does anyone have any
thoughts on this?
