As you probably know, the ASP Command implementation is broken, and has been broken since CS3 was introduced. Yes, that's right, ever since CS3. The last version that actually worked was DW8.
I use ASP Commands to insert, update, or delete database records based on form values passed from another page. Doing it this way allows me to validate the form data server-side, then insert, edit, or delete database rows in multiple tables.
Can you write an extension that mimicks the capabilites of the ASP Command implementation (back when it actually worked)? It's been a real pain to constantly switch back and forth from DW8 to the current version with better CSS tools... I'd be happy to provide screen shots and/or code samples generated from a working version.
