Missing argument 3 for rules_categories_features_export_render() in rules/rules/rules.export.inc on line 96.

hm, what is it why has it gone away? Maybe the feature API changed? Also probably the default should be more an array? If it's not necessary anymore at all, we can remove the parameter (php is fine if you call it with more parameters).

This was my take at it, as I've written Features integration before.

http://drupal.org/files/issues/rules.export.fixFeatures.patch

I haven't look at comment #3. I don't think my patch will apply cleanly to CVS.

Changed default value to array. The latest beta of Features still has code that can pass a third parameter so I'm guessing it's best to leave this in and set a default.

Looks like my patch got eaten last time.

Thanks Tim

Thanks, indeed features doesn't have such a parameter (any more) and rules doesn't it any more either, so I totally removed that parameter.

Removing the 3rd parameter is not technically correct. The hook documentation from the features API file:

/**
 * Component hook. The hook should be implemented using the name ot the
 * component, not the module, eg. [component]_features_export() rather than
 * [module]_features_export().
 *
 * Render one or more component objects to code.
 *
 * @param string $module_name
 *   The name of the feature module to be exported.
 * @param array $data
 *   An array of machine name identifiers for the objects to be rendered.
 * @param array $export
 *   The full export array of the current feature being exported. This is only
 *   passed when hook_features_export_render() is invoked for an actual feature
 *   update or recreate, not during state checks or other operations.
 * @return array
 *   An associative array of rendered PHP code where the key is the name of the
 *   hook that should wrap the PHP code. The hook should not include the name
 *   of the module, e.g. the key for `hook_example` should simply be `example`.

function hook_features_export_render($module_name, $data, $export = NULL) {
  $code = array();
  $code[] = '$mycomponents = array();';
  foreach ($data as $name) {
    $code[] = "  \$mycomponents['{$name}'] = " . features_var_export(mycomponent_load($name)) .";";
  }
  $code[] = "return \$mycomponents;";
  $code = implode("\n", $mycomponents);
  return array('mycomponent_defaults' => $code);
}

Moving to "Provided Module Integrations" component.
