Item8174: Infinite loop in combination with ActionTrackerPlugin

There is an infinite loop when using XpTrackerPlugin in combination with ActionTrackerPlugin (Rev. 3907). It can be reproduced when creating a xpTracker-project. when commonTagsHandler is called, XpTrackerPlugin checks for the "xpsave" parameter and then calls the Func::saveTopicText function. This function in turn triggers the beforeSaveHandler in ActionTrackerPlugin, which releases a call to Func::expandCommonVariables, and then it begins all over again.

As a workaround, i commented out the following line in ActionTrackerPlugins's Option.pm:

$options{$ky} = Foswiki::Func::expandCommonVariables( $options{$ky}, $topic, $web );

a bettwer solution is to drop the request parameter "xpsave" in XpTrackerPlugin.pm:

sub commonTagsHandler
{
### my ( $text, $topic, $web ) = @_;   # do not uncomment, use $_[0], $_[1]... instead

    # search for create new page link
    if( $query->param( 'xpsave' ) ) {
       $query->delete('xpsave');
        xpSavePage($web);
        # return; # in case browser does not redirect
    }
