How to prevent a PDO exception when using Rules to Set a data value after saving new content?

I need to write a rule that edits some elements of the node, as soon as it is created. Unfortunately Drupal doesn’t like that and crashes whenever you try to save the node within a rule that was triggered by “After saving new content”.

Event: After saving new content

Conditions: …

Actions: Set a data value, with Parameter: Data: [node:field-workflow…], Value: 1

The above results in:

PDOException: SQLSTATE[23000]: Integrity constraint violation:

So far I managed to walk-around that with hook_forms, changing the workflow in my portal (so I never have to edit the node just after it is created)

Things get really interesting when I try to use “Execute custom PHP code” action which will change the node value I want:

  1. node_save will result in drupal crushing
  2. db_update – seems to work most of the time…
  3. db_insert – sometimes works (works for superuser only)

Unfortunately all my hacks don’t work for all my problems. How else I can address this situation?
