Chart xmlRepresentation vanishes when report is edited using DEAPI

Migrateduser

<p>I have created a cross-tab report with multi-view and added a chart. I use Design API to manipulate this report to add parameters. When I save the new design,</p>
<pre class="_prettyXprint">
DesignConfig engineConfig = new DesignConfig();
Platform.startup(engineConfig);

IDesignEngineFactory factory = (IDesignEngineFactory) Platform.createFactoryObject(IDesignEngineFactory.EXTENSION_DESIGN_ENGINE_FACTORY);
IDesignEngine designEngine = factory.createDesignEngine(engineConfig);

SessionHandle sessionHandle = designEngine.newSessionHandle(ULocale.ENGLISH);
ReportDesignHandle openDesign = sessionHandle.openDesign("E:/work/birt-workspace/Reports/Report Designs/multi_view.rptdesign");
openDesign.saveAs("E:/Updated_design.rptdesign");

Platform.shutdown();
</pre>
<p>the xmlRepresentation of the chart gets stripped with the following error. Do i need to register any EMF library from Actuate/OpenText?</p>
