[OpenLayers-Users] All vector features in one WFS layer

[Alexandre Dube]

We found a workaround ( thanks to my colleagues Daniel and Julien ).

  My data is originally from MapInfo.  I just opened each table to add a 
column named "Type" and gave a unique value for each one.  Then, in OL, 
used the addUniqueValueRules using the new "Type" attribute they all share.

  Manipulate data is a harsh way ( in my opinion ), but it works so why 
bother ?
