This only works for condition expressions at the moment. But, I have been having an issue with the registration and usage of the dialect. below is how I register it. This is done just before creating the KnoledgeBase ProcessDialectRegistry.setDialect("jexl", new ELProcessDialect()); The xml is as follows: <sequenceFlow id="case15" sourceRef="decision8" targetRef="prompt9">             <conditionExpression xsi:type="tFormalExpression" language="jexl"> ${response['resultSet'] != null &amp;&amp; response['resultSet'][0][0] &gt; 0}      </conditionExpression> </sequenceFlow> But this does not work. If do the following it works perfectly. ProcessDialectRegistry.setDialect("mvel", new ELProcessDialect()); The xml is as follows: <sequenceFlow id="case15" sourceRef="decision8" targetRef="prompt9">             <conditionExpression xsi:type="tFormalExpression"> ${response['resultSet'] != null &amp;&amp; response['resultSet'][0][0] &gt; 0}      </conditionExpression> </sequenceFlow> I realize that from the core xml parser there are some checks for languages and anything other than java, xpath, rule then there is an exception. With some assistance I would be able to make the correct implementation and also for node support. Attached is source. note: I used the Apache Commons JEXL 2.0.1 library -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/623342#623342] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
