Metabox not stored on intial save/publish

[matt2314]

I have added a single text-area to regular posts via AdminPageFramework_MetaBox. With version 3.5.7.1 of the plugin I now have the problem that the value is not stored when I hit save or publish for the first time. On subsequent updates everything works as expected though.

Tested on:

• WordPress 4.1.1 multisite, Admin Page Framework 3.5.7.1
• WordPress 4.2.2 multisite, Admin Page Framework 3.5.7.1

Issue did not happen in those same setups with Admin Page Framework 3.5.6.

Thanks for the report.

I've uploaded a development branch 3.5.8b which includes this fix.

Let me know if it works for you.
