I am new to Qgis and have been following tutorials to learn. I am having difficulty with the polygon tool. First I created a new Shapefile Layer, selected Polygon as the Geometry type, left the Fields list alone, so have a default id Field, gave it a file name (test) and saved it. Then I right-clicked on the layer and selected Toggle Editing. I can then draw a polygon on my map but when finished the right mouse button opens a dialog box with the following:
test – Feature Attributes Actions id NULL It has a choice of 2 buttons, OK and Cancel, but neither seem to work and the polygon I created is erased. The first time I created a layer and added a polygon it worked, but in subsequent tries I keep getting the above dialog box and the polygon is erased. I’ve looked through old messages and found that right clicking outside the map area was the solution, but that is not working either. This seems like a simple exercise, but I am at a loss as to why this quit working.
