Item10022: Upgrading multiple extensions only performs first action

Configure extensions installer: When checking multiple extensions, only the first action gets performed. So instead of upgrading 4 extensions, only the first one gets upgraded.

This isn't good. I've somehow broken this in passing the actions through the password screen. The submit from the extension finder passes in multiple instances of the parameter: (from Firebug:)

Parts        multipart/form-data
time   
processExt   all
action       ManageExtensions
add          Foswiki.org/ToolTipPlugin
add          Foswiki.org/VotePlugin

However the post entered from the password screen only passes through a single instance of the parameter.

Parts        multipart/form-data
time         1289785637
time   
processExt   all
action       ManageExtensions
add          Foswiki.org/ToolTipPlugin
cfgAccess    asdfaqwer

I expect it's a template issue, but I'm not sure yet how to pass multiple instances of the parameter through the form.

The template / form has:

    <#if params??>${params}</#if>

This should be populated by all of the parameters in the query, using the Foswiki query object to return the params.

Debug prints stateements added to lib/Foswiki/Configure/UIs/AUTH.pm seems to show that duplicate parms are not returned. This is a deeper issue in the Foswiki request object.

Thanks to Sven, issue is in Configure/UIs/AUTH.pm where it uses a scalar to return each parameter. Needs to use an array to process multiple value params. See http://search.cpan.org/~lds/CGI.pm-3.50/lib/CGI.pm#FETCHING_THE_VALUE_OR_VALUES_OF_A_SINGLE_NAMED_PARAMETER:
