Re: [rules-users] How to use "from" CE in XML format of rules?

Dear list, I am using 3.1M Release and use the new “from” CE: I invoke a DAO to determine some values from Backend used in the rule: rule ” At least 3 RFQs for material type 1” when $pr: PurchaseRequest(materialType == "1", currentStatus == PurchaseRequestStatus.PRE_APPROVE) $dao : PurchaseRequestFacade() $rfqs: Integer(intValue < 3) from $dao.getRFQsFor($pr) then blockedPRs.add($pr); end So far everything works great, but unfortunately I need to have the rules in XML format: the XML Rules will be modified via WEB-UI by Business-Users using XMLBeans API in the WEB-Application. I like the DRL format more and write initially the rules first in DRL and then use the XMLDumper-Class statically to generate the XML Version of the rules. But while converting from DRL to XML, I get following error message for the above rule when parsing "from" CE: no visitor implementation for : class org.drools.lang.descr.FromDescr : org.drools.lang.descr.FromDescr@176cad3 Is “from” CE not supported in XML format? I just need the above rule in XML, but I don’t know how to write it? I also checked the XSD in the 3.1M release jar distribution, but there is stil the old version of the XSD without the "from" CE. Alternatively if “from” is not supported yet in XML at all, is it a way to formulate the above rule alternatively without “from” without changing the application design too much? Or is it a way to manage the rules and their design/parameters in LHS (read, write, modify) in DRL-Format via API? This would be actually my favorite solution :-) I read quickly over the planned Drools BRMS-Blog, But not sure If I can use the BRMS to build a WEB Application on top of it for managing the design of rules? Many thanks in advance for your help, Kioumars
