Hello, I am wondering if what I am trying to accomplish here is possible. I have a listpage that uses USERID to set different filters on the page and this is done on the OnOpenPage() trigger.
I then exposed this page as a webservice and would like to do a similar sort of filtering, but pass an ID as a parameter instead of using USERID. Is there a good way to interact with the page here to set this filter before calling the read_muliple function that the web service offers? I've taken a look a extending the page webservice with a codeunit but from what I can tell this only provides me with a hook to manipulate a specific record, and not the page itself.
