Hi, today I spent a little time for a deeper analysis of the problem with the Trinidad Chart component when using Java 7.
So I directly compared the behaviour between the working version (based on
JDK 1.6) and the faulty version (using Java 7) using the
Java-Script-Debugger of FireBug.
My entry point was the "ApacheChart.createSVG" - function in the
ApacheCart1_2_14.js - library.
Following the function calls in the embedded JavaScript:
a) ApacheChart.createSVG
("j_id24","svgChartj_id24","/ProduktFrontController/adf/svg/chart.svg","width:100%;
height:100%;",null);
...
b) var apacheChart = ApacheChart.createChart(type, model, chartId,
isPerspective, legendPosition);apacheChart.setYMajorGridLineCount(3); ;
...
c) apacheChart.draw();
I compared the behavior:
a) ApacheChart.createSVG() could not find a difference
b) ApacheChart.createChart() could not find a difference
c) apacheChart.draw(); different behavior
try
{
var a53=a51.getSVGDocument();
...
}
catch(e)
leads to an NullPointer Exception, because the result of the function call
"a51.getSVGDocument()" is null.
Rem.: This happens only if I am using Java 7 on server-side !!!
I really don't understand why using a different Java version on server-side
leads to this different / faulty behavior on client-side.
Any ideas?
Sincerely
Steffen
