hopefully simple question here: say i've used kineticjs draw line follows: var redline = new kinetic.line({ points: [73, 70, 340, 23, 450, 60, 500, 20], stroke: "red", strokewidth: 15, linecap: "round", linejoin: "round" }); and it's been added layer has been added stage. but need remove line if never there react user event. how go doing this? let's have layer below: var layer = new kinetic.layer(....); to remove redline layer write: layer.remove(redline);

i working on relatively simple packet capture application, , using jpcap library. has been working until added in save feature program. my write function public void write() { try { writer = jpcapwriter.opendumpfile(captor, filename); } catch (ioexception e) {e.printstacktrace();} (packet packet : this.packets) { writer.writepacket(packet); } writer.close(); } it correctly gets captor , filepath, loops through packets successfully, when tries write @ end of code block, jvm crashes. my question is, why application crash when trying close jpcapwriter? update : weird thing discovered, is writing file. crashes after write. added print statement after close, , never reaches it. i found several other people same issue me. i'm not sure why removing call close writer fixed problem. file writes correctly, , has no issues. now, content working, may come issue @ later date. update: turns out the file closes when call made stop capt...
