Title:
  Too many view columns during parallel editing

Status in Mahara ePortfolio:
  Fix Released

Bug description:
  We have a Mahara 1.2.5 on a Linux server with MySQL Database.

  During a Mahara Tutorial 25 people where editing a group view in parallel using the buttons add and remove columns. 
  After a while, displaying the view ended in a system error. A look in the database revealed that the view had 7 as the number of columns and (null) as its layout.  Default layouts are only available up to 5 columns. 
  The function  get_layout() in lib/view.php could therefore not determine a layout anymore. 
  I believe this is a Mahara bug. There should be some transactional mechanism between the JavaScript and the PHP script that prevents users from creating more than 5 columns in a view. 

  I just hacked the get_layout function to simply set the number of
  columns to 5 in case it's bigger than 5, but this is not a permanent
  solution.

  Thanks in advance
