[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-3750) add time series charts

[ https://jira.jboss.org/jira/browse/JBSEAM-3750?page=com.atlassian.jira.pl... ] Alain Raynaud commented on JBSEAM-3750: --------------------------------------- I looked at the example in itext, however the timeseries tag is using an empty dataset: dataset="#{chartseries.dataset}" (in chart.xhtml). All my attempts at populating the dataset from Java have failed. I keep bumping into this error: Caused by: java.lang.IllegalArgumentException: Cannot convert org.jfree.data.category.DefaultCategoryDataset@28dd6067 of type class org.jfree.data.category.DefaultCategoryDataset to interface org.jfree.data.general.Dataset I can even manage to have the two class names be exactly the same (Dataset), so the error message baffles a beginner like me. I have tried stuff like (taken from an example): <p:chart chart="#{myEntity.chart}"> </p:chart> public JFreeChart getChart() { return createChart(getDataset()); } private JFreeChart createChart(Dataset dataset) { JFreeChart chart = ChartFactory.createStackedBarChart( "Public Opinion : Torture of Prisoners", "Country", // domain axis label "%", // range axis label (CategoryDataset) dataset, // data PlotOrientation.HORIZONTAL, // orientation false, // include legend true, // tooltips? false // URLs? ); return chart; } @BypassInterceptors public Dataset getDataset() { DefaultCategoryDataset dataset = new DefaultCategoryDataset(); dataset.addValue(81.0, "Against all torture", "Italy"); return dataset; } -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
