Firefox 3 intermittent raster display

[Tom Chadwin]

Hello

Compare IE7/WinXP and FF3/WinXP display of:

http://maps.northumberlandnationalpark.org.uk/

IE7 works correctly. FF3 fails to display rasters on many occasions (including the initial view). Zooming will sometimes bring back the rasters, and sometimes even panning will cause them to appear. I have not determined if the precise same zoom/coordinates will always give the same results as far as the display of rasters goes, or whether it is truly intermittent.

Can anyone help with this?

Many thanks

Tom

Have you tried using fiddler to see if any http errors are occuring?

nothing in the mapguide or webserver error logs

All results are 200 - no sign of any problem.

Nothing that I can see, no.

I am not seeing them. How are you triggering them?

Any other ideas? Just to check: are you seeing the same behaviour as me?

As far as i could tell the raster's loaded ok, it's a little hard to
tell without knowing the map,
but here were no glaring holes from missing rasters

just on the initial load i got the following error

Error: reqParams is not defined

also

V odd. So you see the same initial view as in IE7? How about if you zoom in a few times? The map should always have raster tiles (or vector if you zoom in a long way) underneath any of our vector data, unless you go somewhat outside the main boundary polygon. In other words, if you are seeing a white background, but you are within that polygon, that is wrong: there should be base mapping of some kind visible at all zooms.

To simplify matters for testing purposes, turn off the "Local Development Framework Map" layer group. All you should then see is our boundary over the base mapping. Base mapping of some kind should always be visible within that polygon. For me in FF3, it is not at the initial view, nor at many other views/zooms. In IE7, it is always there.

I found those too, subsequently. I don't know what is causing that. I have manually patched ajaxmappane.templ as per instructions in an earlier thread (changing from POST to GET in RequestMap(), SetSelection(), ZoomSelection(), and RequestHyperLinkData()) in order to get it working in FF3. I noticed in addition that some code was in a different location in the patched version of RequestHyperLinkData(), so I moved it. Has that got rid of the Javascript error? Looks like it might have done. It hasn't fixed the missing rasters, though.

Thanks

Tom

I just double-checked Tom's FF3 patch. I hadn't realized there were patched binaries too (MapAgent.exe and isapi_MapAgent.dll). I've now put those in place too (I assume mod_mgmapagent.so is a source file, so I don't need to worry about it). No change in behaviour, though.

You need to copy the .so file in also for Apache.

Thanks, Martin. I'm on IIS, so no problem.
