Hi Mridul, Thanks for the reply. But <complex-alias> does not work if I want it in a view-entity which is created using other view-entities(I think somebody mentioned on my that post earlier that its a bug and he will look into it and if not resolved he will create JIRA issue). It just works if i need to create a view-entity using two entities.
If I could use <complex-alias>, then my life would have been much easier. I have following simple Query - SELECT with WHERE clause in a Java Method. But I need to have SUM(OTCMAdjustmentAmount). (Here OrderAndTax is a view-entity created using two other view-entities.) -------------------------------------------------------------------------------------- List fieldsToSelect = UtilMisc.toList("OTCMAdjustmentAmount"); EntityConditionList whereConditions = new EntityConditionList(UtilMisc.toList( new EntityExpr("OTCMOrderNo", EntityOperator.EQUALS, OTCMOrderNo), new EntityExpr("OTCMAdjustmentAmountType", EntityOperator.EQUALS, "SALES_TAX") ), EntityOperator.AND); orderTaxObject = delegator.findByCondition("OrderAndTax", whereConditions, null, fieldsToSelect, null, null); -------------------------------------------------------------------------------------- I really appreciate your help.
