[mapserver-users] mergeNewParams and Tile Manager in 2.13.1

[Donald Kerr]

I am working towards upgrading my current working copy of Openlayers which
is a master version from Github downloaded on 7th January 2013.

 

I use mergeNewParams on a WMS layer to retrieve new tiles changed from
Mapserver (swaps colour tiles for greyscale and vice versa but that's
irrelevant):

 

layerOSWMS.mergeNewParams({'FORMAT': 'png_grey'});

 

When the above is called using the master version download from 7th Jan,
each replacement tile appears one after the other as I would expect. With
2.13.1, it appears that all the tiles are downloaded and all appear visually
at the same time after a short delay.

 

Has this anything to do with the new Tile Manager and what can I do to
revert to the old style tile replacement where they are rendered on screen
as they are downloaded? "tileManager: null" doesn't seem to make any
difference besides I would probably not want to turn all features of the
Tile Manager off.

 

Many thanks.

 

Regards,

 

Donald
