Notice: Trying to get property of non-object in _workflow_rules_workflow_get_options() while adding condition "Content has Workflow state" in rules

Same problem :
I'm checking the state transition of a node to create a new revision.
On this rule, which use workflow_rules, I've got this error in line 39.

My configuration is :
rules : version 7.x-2.7
workflow : version 7.x-2.4

Workflow_rules (workflow submodule) is also activated

You just have to add an '@' sign before it. Its working though even for that message

Are you using Workflow Node or Workflow Field?
For Workflow Node this is indeed an error. For Workflow Field, you should use :
- condition Entity is of or Entity has Field
- condition Data Comparison.

I'm using workflow Node module.
Workflow field is not activated.

@ is not a solution, this is only a "subterfuge" to undisplay the message error.

This is my configuration :
Events : the workflow state has changed
Conditions : Content has a workflow state
Data selector value of my condition element is set to node

when the condition is done, this error message is displayed
Notice : Trying to get property of non-object dans _workflow_rules_workflow_get_options() (ligne 39 dans /var/apps/drupal/sites/all/modules/workflow/workflow_rules/workflow_rules.rules-callback.inc).

I'm not using workflow field, but I'm thinking about when I saw it...

Have a nice day and tell me if you need more details to replicate the bug

I have delete the event and recreate it.
The error has gone.... I think it can be closed.

Adjacent commit should fix the problem. Please try latest dev- release.

The fix from #7 did not make it into 7.x-2.4

Correct. The pro lem is in 2.4, and fixed in the next version, until then in dev version.
