I havde made an custom web login form for my webserver and configured the server to use it via the domcfg database.
The problem is that when the server uses the login form it does not honour the value in the $$HTMLFronMattter field but instead replaces it with: .
I think this is sub-optimal.
Subject: $$HTMLFrontMatter and custom login form
Sub-optimal, maybe – but $$HTMLFrontMatter (and $$HTMLTagAttributes and &OutputFormat=JSON) are essentially back-ports of new Domino 8 features. Different code handles the forms in domcfg and “normal” NSFs, and the domcfg code was not modified (and almost certainly will not be modified) in the Domino 7.0.x code stream. Remember – you’re a version behind now.
