#4316: Widgets with multiple instances (like RSS or Text) not receiving $number

 Priority:  normal      |   Milestone:           
Component:  General     |     Version:  2.2      
 Severity:  normal      |    Keywords:  widget   
------------------------+---------------------------------------------------
 In v2.2, the new widgets infrastructure does not appropriately pass a
 $number argument to widgets that have multiple instances (i.e. widgets
 like the RSS and Text widgets, which have more than one instance--but this
 defect does NOT apply to the RSS and Text widgets themselves, since they
 were updated with 2.2).

 Example: I have two widgets in the plugins repository. Neither is
 receiving a $number parameter. These are the only arguments being passed:

 {{{
     [name] => Sidebar 1
     [id] => sidebar-1
     [before_widget] => <li id="kb-advanced-rss-2" class="widget 2">
     [after_widget] => </li>
     [before_title] => <h2 class="widgettitle">
     [after_title] => </h2>
 }}}

 There also needs to be
 {{{
     [number] => 1
 }}}

 Otherwise instances after the first of this widget look exactly like the
 first instance.

 My two widgets are among several in the wordpress.org plugins repository
 that are modeled after the previous RSS and Text widgets, using the exact
 same method to allow users to have multiple instances. Thus, this defect
 has probably broken many, many plugins.

 I've patched my plugins with a messy workaround that extracts the number
 from the class in "before_widget." But fixing this defect is necessary for
 backwards compatibility, i.e. so the same widget can be used in older and
 new versions of WP.
