Rules integration for updating fields on flagging

Hi,

We have a requirement for a global flag but tracking the user who flagged. To do this, we set up a global flag and added an entity reference field to it.

To get it to work, we tried setting up a rule to be fired on flagging. However, it seems to have multiple issues.

Firstly, I needed to add a condition - flagging is of bundle . This fails with the following

Call to undefined method stdClass::type()

I was able to work around this by calling entity_metadata_wrapper on the flagging object before passing it to rules. However, the bundle check fails for reasons unknown.

As a workaround, I changed to check to "entity has field ". This check passes correctly.

I need one of the above checks before Drupal will let me call the "Set data value" action on flagging:

However, when I have set the action to set flagging: to site:current_user, it fails with the following (from rules debug)

22.377 ms Unable to apply data selector flagging:field-user. The specified variable is not a list or a structure: Property .
22.527 ms Unable to evaluate action data_set. [edit]
23.089 ms Evaluating the action entity_save. [edit]
23.335 ms Rule Inaccurate Flagging has fired.

Is there a way to work around this? I am happy to dig through code and apply a fix if you can point me in the right direction.

Thanks...
