<p>Hello,</p>
<p> </p>
<p>I'm working with BIRT since some month now and integrating it into our webapplication. We use the design API to generate a reportdesign on the fly and add user input to the reports.</p>
<p>As we came to implement the feature of TableGroups we were happy, that this was done straight forward.</p>
<p>On our server we have the java flag "-ea" (enable assertions) set and get an AssertionError when adding a TableGroup to the table.</p>
<p> </p>
<p>I prepared a sample test code that works when run without flag "-ea":</p>
<pre class="_prettyXprint _lang-js">
@Test
public void testCreateReportDesign() throws BirtException {
DesignConfig config = new DesignConfig();
Platform.startup(config);
IDesignEngineFactory designEngineFactory = (IDesignEngineFactory) Platform.createFactoryObject(IDesignEngineFactory.EXTENSION_DESIGN_ENGINE_FACTORY);
IDesignEngine engine = designEngineFactory.createDesignEngine(config);
SessionHandle session = engine.newSessionHandle(ULocale.GERMAN);
final ReportDesignHandle design = session.createDesign();
final ElementFactory elementFactory = design.getElementFactory();
SimpleMasterPageHandle masterPage = elementFactory.newSimpleMasterPage("Page Master");
masterPage.setOrientation(DesignChoiceConstants.PAGE_ORIENTATION_LANDSCAPE);
masterPage.setPageType(DesignChoiceConstants.PAGE_SIZE_A4);
design.getMasterPages().add(masterPage);
// set label on masterpage
LabelHandle label = elementFactory.newLabel("cap_report");
label.setText("testheading");
masterPage.getPageHeader().add(label);
TableHandle table = elementFactory.newTableItem("mainTable", 1);
table.setProperty(IStyleModel.TEXT_ALIGN_PROP, DesignChoiceConstants.TEXT_ALIGN_CENTER);
table.setWidth("100%");
// table.setProperty(TableHandle.DATA_SET_PROP, DATASET +"main");
design.getBody().add(table);
ColumnHandle column = elementFactory.newTableColumn();
table.getColumns().add(column);
TableGroupHandle group = elementFactory.newTableGroup();
group.setName("groupTest");
Expression exp = new Expression("if(1=1){\"1\";}", ExpressionType.JAVASCRIPT);
group.setExpressionProperty(IGroupElementModel.KEY_EXPR_PROP, exp);
table.getGroups().add(group);
}

<p>When adding the flag we get the following stacktrace:</p>

<div>What am I doing in wrong? Is the only solution to disable assertions?</div>
<div>What is this namespace check for?</div>

<div>Many thanks for any answer!</div>
<div>Kind regards, Georg</div>
