Alfesco -OnlyOffice - Alwas the same document open...

[Buliwif]

Hi,

When I create a new document in /share, Onlyoffice open and show a new document.
I type text and modification seems correctly saved. Cause When I close the window of th document server and refresh the /share page, the document preview shows my text.
But When I click on the "modify with onlyoffice button", it reopen a new doc which will crushed the other.
It looks like a simple wrong parameters but where ?

Thank You :)
