Error updating Spline

Hallo guys,

I get the following error when ill add a new DateSeriesPoint to the chart. I already re-compiled and downloaded a new js folder.
Any idea's? It shows that it cant render it. Im thinking of a widgetError somehow.

JavaScriptException: (TypeError): l is undefined stack: ((void 0),0,[object Array])@http://localhost:8080/AQV/VAADIN/js/highcharts.js:32 ([object Array],(function (l) {l.render();}))@http://localhost:8080/AQV/VAADIN/js/highcharts.js:68 ()@http://localhost:8080/AQV/VAADIN/js/highcharts.js:32 ([object Object],0,[object Array])@http://localhost:8080/AQV/VAADIN/js/highcharts.js:45 ([object Array],(function (da) {if (da.isDirty || w) {da.redraw();w = true;}}))@http://localhost:8080/AQV/VAADIN/js/highcharts.js:68 j()@http://localhost:8080/AQV/VAADIN/js/highcharts.js:45 R3([object Array],[object Object])@http://localhost:8080/AQV/VAADIN/widgetsets/com.xyleminc.aqv.widgetset.AqvWidgetset/4EAE309AA6CEF3610DFA0CCB2AC46230.cache.html:4083 wib([object Object])@http://localhost:8080/AQV/VAADIN/widgetsets/com.xyleminc.aqv.widgetset.AqvWidgetset/4EAE309AA6CEF3610DFA0CCB2AC46230.cache.html:4051 bhb([object Object],[object Object],"{\"changes\":[[\"change\",{\"format\": \"uidl\",\"pid\": \"PID369\"},[\"24\",{\"id\": \"PID369\",\"immediate\":true,\"type\": \"switch\",\"v\":{\"state\":true}}]],[\"change\",{\"format\": \"uidl\",\"pid\": \"PID370\"},[\"27\",{\"id\": \"PID370\",\"height\": \"300px\",\"width\": \"250px\",\"immediate\":true,\"isRetrieveSVG\":false,\"isPrint\":false,\"reloadChartSeries\":false},[\"options\",{},[\"title\",{\"text\": \"Volume\"}],[\"subtitle\",{\"text\": \"the amound of volume in the last hour \"}],[\"credit\",{},[\"position\",{}]],[\"legend\",{}],[\"tooltip\",{\"formatter\": \"function() { return '' + $wnd.Highcharts.dateFormat('%d %m. %Y <\\/b>\\t\\t\\t\\t\\t\\t\\t\\t\\t\\t\\tTime: %H:%M:%S', this.x) +' \\t\\t\\t\\t\\t\\t\\t\\t\\t\\t\\t'+ this.y +' mNAP ';

Solution:
- The error occured, because the plotline couldnt be found. Afther deleting (using the default plotline) it worked
