RE: Hide Preview Button Based On File Extension

Hiding the preview is just a little exercise! It's not actually going to be implemented.

Although I did get this error

Edit: Fixed it and it seems to work now

This is rudimentary of course but it should be a matter of setting, say, the "disabled" parameter to "TRUE" when the extension is "PDF" (though, separately, i'm confused why you'd want to hide preview for PDFs, as PDFs are one of the best things that CAN be previewed in Appian's Document Viewer Field...)

a!buttonWidget(
  label: "",
  icon: "eye",
  tooltip: "View",
  value: true(),
  disabled: document(fv!row, "extension") = "pdf",
  saveInto: {
    local!preview,
    a!save(local!selectedDocument, fv!row)
  }
)
