[OpenLayers-Users] layer.mergeNewParams flicker

[Bart van den Eijnden (OSGIS)]

Hi Chris,

when I do that I get problems:

bottomLeftTile has no properties
file:///D:/sources/OpenLayers-2.5-rc2/lib/OpenLayers/Layer/Grid.js
Line 250

Followed by:

tile has no properties
file:///D:/sources/OpenLayers-2.5-rc2/lib/OpenLayers/Layer/Grid.js
Line 523

Example file to reproduce attached.

Thanks in advance.

Best regards,
Bart
