Hi Jason, it's me again I finally can find my problem (is about datatypes), but can't fixed =( The situation: I have a dataset who is filled by a POJO if(count < stock.size()){ row["puntuationChart"] = stock.get(count).getSectionPoint(); row["sectionChart"] = stock.get(count).getSectionName(); row["resultChart"] = stock.get(count).getSectionResults(); count++; return true; } return false; The column named ‘puntuationChart’ is the problem…. This column is type=Decimal, and I filled it with a POJO’s property type = double, just like this example http://www.vogella.de/articles/EclipseBIRT/article.html (I did the example and works fine). The only difference between my project and the example project is that in Java i first have a String, then convert to double and then I set it to the POJO’s property: public List getAnswerValues(String answerTot) { String[] answersStr = answerTot.split(","); List answers = new ArrayList(); for (int s = 0; s < answersStr.length; s++) { Answer answer = new Answer(); double point = Double.parseDouble(answersStr[s]); answer.setSectionPoint(point); answers.add(answer); } return answers; } When I execute the proyect, get this warning: Feb 14, 2012 3:10:30 PM org.eclipse.birt.chart.internal.datafeed.ResultSetWrapper initializeMeta WARNING: Unable to determine data types from resultset But this warning only is showing when the project is executed, when use the BIRT preview works fine Could you please help me?
