I have a web form, where people can upload one or more attachment.

When the form open, I have this URL :

formname!openform&param1=test1&param2=test2

and the WebQueryOpen run normaly

Once I upload a file (using the @Command([FileSave]) and the File Upload Control)

I get this URL :

formname!openform&param1=test1&param2=test2&Seq=1

and the WebQueryOpen run normaly

But if I want to upload 2 or more item :

I get this URL right after the 2nd upload :

/0/4611a8cd6065d52b85257553006d8ee4!EditDocument&Seq=2

The WebQueryOpen doesn’t run AND , Im loosing all my parameters…

What going on ? any clues ?

I know I must have a temporary document to hold the attachment while finishing filling the form before I save it to the right place…
