[OpenLayers-Users] Bug possibly related to ticket #1910

[Atle Frenvik Sveen]

Hello all!

This may be related to Ticket #1910, although I’m not 100% sure. This
ticket was the one that lead me onto this problem, so thought it might
be relevant information here.
 
  
 
 I encountered an error: 
 
 “Webpage error details
 
  
 
 User Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1;
Trident/4.0; .NET CLR 2.0.50727; .NET CLR 1.1.4322; .NET CLR

 Line: 159
 
 Char: 13
 
 Code: 0
 
URI:

In IE 8 running in compability view on Win XP.
  
After digging a bit I tracked my problem down to being related to four
factors:
 
  
 1)The use of IE7 (or IE8 in compability mode)
 
 2)The use of a vector layer
 
 3)Using tables as part of my laout (don’t ask why)
 
 4)Initializing OpenLayers from inside a <table>-tag on the page
 
  
 
 I’ve managed to recreate the issue by modifying the
http://dev.openlayers.org/releases/OpenLayers-2.8/examples/vector-features-with-text.html example. What I’ve done is two things:
 
  
 
 1) Adding a <table><tr><td></td></tr></table> block around the
body-content
 
 2) Moved the init()-call from the body onLoad to a <script>-tag inside
the table (but below the map div)
 
 This file is attached (I’ve hard-coded in references to javascript and
css on openlayers.org).
 
  

 It seems to me that line 159 in VML.js, which is dealing with page
elements (at least that is what I recon) somehow gets confused by the
addition of tables. 
 
  
 The easy fix is of course either to skip the use of tables, or move the
<script>-bloc down below the tables. Other than that am I clueless on
how to fix this issue, neither am I sure if this is related to ticket
#1910. 
 

For me the problem was resolved by appying my simple fix, but I thought
someone might be interested in investigating this further.
