Doesn't work with Content Management Filter module

Well it's because cmf uses it's own form (cmf_admin_nodes_form), don't know why it isn't simply rewriting the core node module's node_admin_content form like this module does. Cmf developers maybe have their own reasons. So the solution is easy, you need to properly alter the cmf_admin_nodes_form too. I'll post a patch for this after i find out how to create one :)

ok here it is, wasn't so hard :)

Sorry I wasn't getting alerts from the queue here.
Nice clean patch applies fine.
I've put it in - trusting it does what it says. Visual review looks fine and it doesn't break anything, but I've not tried the other module.

So, committed to -dev. Thanks!

You can trust it, tested it just now and works like a charm!
Thanx!!!

dman,

Will you commit and release a new version? Latest release is over two years old so it wouldn't hurt to release a update version :)

Cheers

Here is the code to replace taxonomy_multi_edit/module to work with CMF and with the Array bug fixed.

/**
 * @file Adds term tagging to the node admin screen
 * 
 * Adds an action to the node operations drop-down found in admin/content/node
 * This is suitable for adding one term to many nodes.
 * 
 * Provides a new tab alongside admin/content/node where all terms are listed
 * next to their nodes. This provides more finely-grained control, but is a bit
 * clunkier.
 * 
 * Note this code includes a hack in 
 * taxonomy_multi_edit_operations_categorize()
 * that peeks at the raw form submission (non-FAPI) because the node admin form
 * does not allow for extra information. Node operations are atomic and binary,
 * but I needed to add a modifier (which terms to add) to that process.
