[OpenLayers-Users] setting WKT returned from postGIS in form field to openlayers feature

[Burgholzer,Robert]

My application returns a WKT representation of an element geometry in a
hidden form field.  I am trying to take that geometry and push it into
an openlayers feature layer, so that as the user goes views different
elements from the PG server, those features appear in the foreground on
the OL map.

 

I have tried to implement some code from the WKT example, but I am not
having any luck.  The feature fails to draw, although I know it is
there, because I have been using an alert() to show me the contents of
the WKT string.  Thus, I am guessing that somehow my format returned
from PostGIS is incorrect.  Here is the contents of my hidden form
field:
