add_post_meta/update_post_meta and cache

[nofearinc]

I have a custom post type with 2 fields for price, second one has 5% discount and I want to populate it automatically by hooking to 'save_post'.

I have a working logic that calls update_post_meta() (or add_post_meta() ) for the second field but it doesn't get executed even with several post updates. However, if I end my function call with a var_dump that outputs the values from the function, everything goes smooth.

It looks like some caching issue to me that gets flushed per var_dump call, anyone able to reproduce?

It's been a while, but can we see some code @nofearinc?

It sounds like some missed wp_is_post_revision() checking. I'm leaning towards a worksforme.

@ericlewis it's been quite some time and haven't been able to reproduce that ever since, it was probably fixed months ago. Marking it as "invalid" and if anyone is able to reproduce, we could reopen.

@nofearinc I actually ran into this today but need some time trying to reproduce on a clean install before reporting anything further.

Just in case anyone else does run into this changing priority to something lower than 10, e.g., 99 some how fixes this.

I've yet to properly test this on a trunk install further so let's keep it closed for now.
