Hello, I posted a question previously relating to this that unfortunately has not had any replies - I'm hoping to get this resolved.... I have the same problem whereby the file's downloaded then any subsequent action on the page causes the file to re-download. I have added the saveSerializedView method but to no avail.
The action is triggered via a command link - now if I replace the command link with a command button this issue goes away; but I really don't want to use a button if I can help it! Can anybody help me with this please? Many thanks in advance, Carl Jeff Bischoff wrote: > > David, > > Thanks for the hint.
