我有一個使用DynamicJasper創建報表的項目。到目前爲止它運行良好,但是當我想將圖表添加到以前的功能性報表時,我遇到了問題。在DynamicJasper圖表中使用CustomExpression
我不斷收到這樣的:
net.sf.jasperreports.engine.design.JRValidationException:報告設計無效: 領域未發現:customExpression_for_Ganancia 在net.sf.jasperreports.engine。在net.sf.jasperreports.engine.JasperCompileManager.compileReport(JasperCompileManager。)中的net.sf.jasperreports.engine.design.JRAbstractCompiler.compileReport(JRAbstractCompiler.java:140) 上設計(JRAbstractCompiler.java:258) 。 java:215) at ar.com.fdvs.dj.core.DynamicJasperHelper.generateJasperReport(DynamicJasperHelpe r.java:519) at ar.com.fdvs.dj.core.DynamicJasperHelper.generateJasperPrint(DynamicJasperHelper.java:279) at ar.com.fdvs.dj.core.DynamicJasperHelper.generateJasperPrint(DynamicJasperHelper.java:232)
Ganancia是圖表中唯一一個CustomExpression列。如果我不將此列作爲一系列添加到圖表,則圖表正確呈現。看來,圖表不會用表達式發揮好...
一個從我的代碼片段:

正如我所說,該報告是正常顯示沒有圖表,用圖表,它失敗只有當表達式列作爲一個序列被包含時。
歡迎任何想法!
DJ版本3.2.4修復了問題也:承諾是6818489很快釋放sourceforge – 2012-06-25 15:49:59
太棒了!我不希望這些迴應在一年之後纔會到達,最重要的是要固定在項目本身上:D非常感謝! – Johnco 2012-06-26 22:16:17
