Fix committed to master branch: http://bugs.limesurvey.org/plugin.php?page=Source/view&id=9886

New 2.00+ Build 121016 released.

The fix induced another bug - did not know whether to open another bug or reopen this one.

Steps to reproduce:

1. logon
2. Click on the Tempate Editor icon - results in an error:

Undefined variable: surveyid

C:\xampp\htdocs\limesurvey\application\helpers\replacements_helper.php(771)

Suggestion for fix (replace line 771 with the following):

if (isset($surveyid) && isset($SESSION['survey'.$surveyid]) && isset($SESSION['survey'.$surveyid]['register_errormsg']))

The fix to replacements_helper.php is missing a istantiation of the global $register_errormsg. Appears that there is a cross over here in there is a change towards an array ($thissurvey[register_errormsg]) - the new logic:

if (isset($surveyid) && isset($_SESSION['survey_'.$surveyid]) && isset($_SESSION['survey_'.$surveyid]['register_errormsg']))
{
    $register_errormsg=$_SESSION['survey_'.$surveyid]['register_errormsg'];
    unset($_SESSION['survey_'.$surveyid]['register_errormsg']);
}

will not work with the $thissurvey[register_errormsg]. We need to either set a global for $register_errormsg or finish moving to the array.

That part is obsolete and will be removed.
