I have an auto action that triggers when a user changes a field on their profile. However what I am trying to achieve is for it to not trigger if they change the field to nothing (it is a list of choices so they can select one or just select the blank line at the top to clear it.)

I have tried conditions of :

[var1_cb_test] NOT EMPTY

[var1_cb_test] DOES NOT CONTAIN ""

[var1_cb_test] IS NOT REGEX ^$

but none of these stop it from triggering - how should a detect when a field is 'blank'

Thanks

Thanks that gets it to work now, however I'm now seeing another odd behaviour.

I have this variable (the one that if changed by the user triggers an auto action) set with Ajax enabled and I then display it on a page using the CB Content module. If the user changes it to a blank entry (from the drop down) the animated timer is shown and this stays their without the screen ever updating (see attached.)

If I turn off the AutoAction entry it works fine in terms of updating on the screen after the user changes it, so there seems to be something going on. (the change does actually happen as if you reload the page it shows the field was changed.)

I am essentially copying what is explained in the Tutorial example for CB Autoactions but with an extra check, since otherwise if a user selects the top (blank) entry for their current their mood (field) CB Activity displays that the "mood is " so I added an extra condition (before the check for the change of variable) to check the new value is not blank.

I display the Mood field in a CB Content module to allow the user to edit it from that page (so I have enabled Ajax on that field.)

The page they are on does have the activity stream showing but as the condition is set to not trigger if they change the field to blank then, if anything, I would have expected if there was any conflict it would happen the other way around?

If they change the field from one value to another value rather than to set it as blank/empty, then it all works fine.
