I add DrawFeature control on map for OpenLayers.Handler.Path or
OpenLayers.Handler.Polygon. These two controls use 'double click' to
conclude the input of a linestring or a polygon.
I also add a OpenLayers.Control.NavigationHistory on map, and few
self-defined OpenLayers.Control.Buttons.
If I choose the control DrawFeature for OpenLayers.Handler.Path or for
DrawFeature-OpenLayers.Handler.Polygon as current control, and then double
click on a OpenLayers.Control.Button or
OpenLayers.Control.NavigationHistory, there will be a error message
(runtime-error: 'this.line.geometry' is null or not an object) occurred with
function 'dblclick' of 'Path.js' or 'Polygon.js', as follows
dblclick: function(evt) {
if(!this.freehandMode(evt)) {
var index = this.line.geometry.components.length - 1;
this.line.geometry.removeComponent(this.line.geometry.components[index]);
if(this.persist) {
this.destroyPoint();
}
this.finalize();
}
return false;
},
