If I add the drawing-layer to the map before an action is triggered and remove the "add vector layer" handler in each tool, I can still draw, but I can´t
modify the drawings!?!</span></div><div style="background-color: transparent; "><div style="background-color: transparent; color: rgb(0, 0, 0); font-size: 13px; font-family: arial, helvetica, sans-serif; font-style: normal; "><span style="font-family: arial, helvetica, sans-serif; font-size: 13px;"><br></span></div><div style="background-color: transparent; color: rgb(0, 0, 0); font-size: 13px; font-family: arial, helvetica, sans-serif; font-style: normal; "><span style="font-family: arial, helvetica, sans-serif; font-size: 13px;">Here is the code showing a working version where the modify tool works.
