I've put a call out on the OTN APEX forum asking for suggestions from the community on what they think are frequent APEX questions, be it within the forum or elsewhere.
In part, I'm chasing ideas for content in future presentations, or blog posts. I welcome others to do the same. I think if we share our perception of common questions, better resources will come.
So please, feel free to contribute in any way, shape, or form.
What questions do you see or hear all the time?
If for some bizarre reason you don't have an Oracle account for the OTN forum, just reply to this post, ... then register an account. It covers you for the forums, livesql.oracle.com, the Dev Gym, entitles you to download stuff like SQL Developer, and no doubt more.
Though probably no steak knives.
