When generating a square lattice graph under some circumstances a line segment (instead of graph) appears in the map view.
Reported by Matthias Filter

NumberFormatter was causing locale-specific behavior when converting latitude and longitude double value into a string when generating a lattice.  This was breaking inlined spatial URIs (comma-separated value list), causing unusual behavior (in this case, a straight line is drawn)

This bug is fixed. Use of NumberFormatter was a problem because of internationalization (',' vs '.'). It  
led to non unique URI's in the graph that showed up because we use  different locales.
There was no error because the generated inline polygon data was CSV anyway but the uri's were not unique and the appended
generated String in the non-US local produced nonsensical (but syntatically valid) sets of coordinates. The problem has been 
fixed by avoiding use of the number formatter in appending a unique segment to the UID.
The fix  will show up in the next regular build end of next week.
