[MAPSERVER-USERS] Problems with scalebar embedding and java mapscript

[maurosa]

Hi list 

I am experiencing problems with scalebar embedding 
after version 5.02 using java mapscript. 

Changing map extent, does not change scalebar values. 
Version 5.02 works properly. 
The error happens with version 5.20 and 5.21. 

If scalebar usage is changed after version 5.02, 
I thank you for any suggestion.

This is a simple java mapscript program to reproduce the error: 

--------------------------------------------- 

System.loadLibrary("mapscript");       

//first extent: scalebar values are correct 
mapObj map = new mapObj("mymap.map");       
imageObj img = map.draw();       
img.save("mymap1.jpeg", map);       

//second extent: scalebar values are wrong 
//and are frozen to those of first image 
map.setExtent(300000, 4800000, 900000, 5200000); 
img = map.draw();       
img.save("mymap2.jpeg", map); 

//from this point on, changing map extent does 
//not change the original scalebar values any more 

--------------------------------------------- 

The following is mymap.map:
