To reproduce:

1. Create an openlayers_wkt cck field with an openlayers map widget as the preset. I used a custom preset created in the preset interface.
2. Create a different field with 'unlimited' possible values. I used a file field.

When you press 'add another' to the unlimited field, you get the following error:

warning: array_merge_recursive() [function.array-merge-recursive]: recursion detected in /var/www/opendev/drupal6/sites/all/modules/cck/includes/content.node_form.inc on line 379.

It's definitely openlayers, as hacking content.node_form.inc like so fixes it:

  foreach ($javascript['setting'] as $fkey => $fvalue){
    foreach ($fvalue as $skey => $svalue){
      if (strpos($skey,'openlayers') !== false){
        unset($javascript['setting'][$fkey][$skey]);
      }
    }
  }

No resolution yet, but the problem seems to be being caused by openlayers_cck_wkt_element_process being called twice during AJAX.

This is then causing openlayers_render_map to be called twice, adding two identical pieces of 'settings' to the javascript settings array, causing the array merge recursive error.

I was not able to reproduce this error, but when trying I can across this JS error, when I tried to use the "Add another" button for another field (textfield) that has unlimited values:

this.div.appendChild is not a function

Very strange that you can't reproduce. Still getting this in the dev version of openlayers and dev version of cck.

Setup:
1 openlayers_wkt field, single value, all feature-types allowed
1 Text, with unlimited allowed values, widget-type 'textfield'
