Manuel Hartl commented on TRINIDAD-2276:
----------------------------------------
Java6 is End of Live in a few months (November2012) - so i think virtually
everyone has to have a look at java7. Java7 is in it's fifth update release. so
hopfully the issues you speak about are gone :)
> SVG Charts and Java 7
> ---------------------
>
> Key: TRINIDAD-2276
> URL: https://issues.apache.org/jira/browse/TRINIDAD-2276
> Project: MyFaces Trinidad
> Issue Type: Bug
> Components: Components
> Affects Versions: 2.0.1-core
> Environment: Windows7 or Linux 2.6, Tomcat7, mojarra2
> Reporter: Manuel Hartl
>
> Generating of SVG charts with trinidad's component <tr:chart/> does not work,
> when the servlet container is executed in a Java7 runtime environment (tested
> with 7u4 und 7u5).
> It seems that the generated page (so html or javascript) is rendered in such
> a way that some SVG java script function does not work any more.
> Steffen Spahr also has this problem in his project and he did some research
> on it:

> 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
