[Qgis-developer] Dissolve processing alg vs Vector menu group by

[PIERRE Sylvain]

Hi devs,

I found different results when I want to dissolve line vector layer by attribute value :
With Dissolve processing alg,  features are merged but with Multilinestring geometry type for dissolved cases, and Linestring geometry  for other cases.
With group by action from vector menu, all  features get Linestring type.

Is ‘group by’ behavior the right one? In such case should be  Dissolve processing alg improved?
