[Gvsig_english] gvSIG Mobile workspace - getting "WMS image error" after trying to load files from WMS

[Schoolmeesters]

  Hello again,

thank you for testing the WMS. I've tested it again (the NRW one) and 
did not get any picture loaded (no matter which EPSG I choose). On the 
other hand, the OSM one works fine. So I just have to find an adequate 
wms, I think. That is ok.

But concerning the* gps arrow *I've tested again (no map background)

1.) connecting to a GPS device at COM port, showing position @ 8.42171° 
/ 49.00797° ------> arrow is _not _displayed

2.) connecting to a logged nmea file (logged by gvsig mobile, same 
position) -----> arrow is not displayed, either

3.) connecting to an old nmea file (logged by another application, 
approx. same position)  ----> arrow is displayed and even centered to 
correct position (checked with map data)


I'll check whether it will work with another GPS receiver. I don't 
understand, what should be different. It is always nmea code!


However, the position is always displayed correctly. Shouldn't the arrow 
get the position from the same source as the displayed position (button: 
display coordinates)


Regards,

Marcel Schoolmeesters
