Incompatible with Webform 4

Are there any intentions to port this useful module to webform 7.4?
In 7.4. no serials are created.

Yeees, I see the problem. Webform 4 assigns data differently in its hook_webform_submission_presave() and that format isn't compatible with the way the v3 module did things.

If you've already saved data, I might need to have an update hook that unbreaks the (now incorrect) data that was saved with serial 1.x on webform 4. If that broken data remains, the module will keep failing and always save a 0. Luckily the value is computed, so I can at calculate correct values at any time.

Quick fix if you do NOT yet have serial data in a webform 4.x table:

diff --git a/components/serial.inc b/components/serial.inc
index 918b31e..47dedba 100644
--- a/components/serial.inc
+++ b/components/serial.inc
@@ -189,7 +189,7 @@ function webform_serial_webform_submission_presave($node, &$submission) {
         $current = (int)$component['extra']['initial'] - $increment;
       }
 
-      $submission->data[$cid]['value'] = array(0 => $current + $increment);
+      $submission->data[$cid][0] = ($current + $increment);
     }
   }
 }

Alternatively, wait for the 7.x-4.x-dev package.

Instead of a completely new branch, you might be able to fix it with version detection, as was done in Webform Tokens. See #1717934: Support Webform 4.x.

Guessing at a version and hoping it will keep working is pretty yuck. I can probably get away with it for now, but I opened #1941396: API version to hopefully just solve that particular problem once and for all.

Attached is a patch that should solve the problem *and* fix up data was that saved in the incorrect 3.x format if you're on 4.x Please give it a try.

This fix does not correct information previously submitted incorrectly. With these changes 7.x-1.x is compatible with both Webform 3 and Webform 4.

Improved Webform version checking so that it defaults for WF4 when working from git, which causes the version number to be absent.
