Hello,
updateActiveFile(FileInfo) command is intended for updating a complete
active FileInfo instance on the server ( wchich is XML-unaware simple
embedded device, the poscondition of this operation is that current display
output is also updated).
I could've used set operations per each attribute of FileInfo, but there're
more than 20 attributes, including deeply nested ones.
Probably, I'd need to use an XSLT stylesheet on the client side to define a
set of rules, which would tell to the serializer which remaiming elements of
type FileInfo to pass, depending on the value of its first element "mask" ?
Thanks
Siarhei Biarozkin
