Thread:Extension talk:Header Tabs/Issue with Semantic Forms + Header Tabs + multiple instance templates

I've run into an issue where using header tabs in conjunction with multiple instance templates in a form messes up the rendered HTML for some of the form elements. I found this when trying to figure out why autocompletion wouldn't work on fields located not on the first tab. I've been able to duplicate this issue on referata here, and when you view the rendered HTML for the input fields, you'll see that the field on the last tab has the same name as the field in the multiple instance template on the second tab... in other words, data will end up getting saved to a different field than expected.

Thanks in advance for your help,
