Oracle Apex error – document.wwv_flow.submit is not a function

You might occasionally get this error in Oracle Apex when submitting a page.
Alternatively, the page might not submit at all when you click a page button.

I must admit this had me stumped and i had to resort to disabling everything, then reenabling region items to find out what was wrong.

Turns out that APEX does not like the ‘name’ attribute of an element. Remove the name element and the problem goes away. Just use the ‘id’ attribute element instead.

before:
<input type="text" id="username" name="username" class="grey"/>
 
after:
<input type="text" id="username" class="grey"/>

Hope this little tip helps someone.
