Hi Richard,
WFileUpload:
1.1: The current API does not allow that
1.2: The current API does not allow that
1.3: It may work if you call show() after calling upload()?
2.1: I don't think that's possible, unless of course you set reload-is-new-session to true in wt_config.xml, in wich case the createApplication function will be invoked.
3.1: Create a JSignal and trigger it through doJavaScript.
BR,
Wim.
