Category Checkboxes sync to any checkbox array on the edit form

[kevinB]

The javascript which syncs "All" and "Most Used" category checkboxes was rewritten for WP 2.9. The new JQuery code binds to the click event of every checkbox on the form, and synchronizes the category checkboxes with matching value attribute.

In the default configuration it works fine. But if a plugin adds another checkbox array to the form, these checkboxes also become a sync source for the category checkboxes. Category checkboxes are (un)checked when the plugin checkbox is clicked.

This occurs only with plugin-defined checkbox arrays, and only for checkboxes whose values attribute matches a category ID. So there is a limited incidence, but potentially significant severity. The error would presumably also occur with custom taxonomy checkboxes.

To reproduce:

• Activate  Role Scoper plugin

• Edit or Add New Post

• In the Readers metabox, toggle the checkbox of a Group or User whose ID value matches any Category ID (Firebug is helpful here).

Was this handled in #12244 then?

Replying to nacin:

Was this handled in #12244 then?

Yes. Closing this as fixed as this won't be something to go into 2.9 branch.
