Hi,

Michaël seems to work on new linear referencing tools. With good tooltips those 
feel rather self-explaining and I could create points for a selection. However, 
working on a whole layer does create points for me, just a new, empty layer.  I 
thought it might be because I had only one feature on the layer and I digitized 
a few more. In addition I made an attribute "om" (String) for grouping the 
features and this time I managed to get an error:

java.lang.IllegalArgumentException: Unknown attribute name: om
