Hi, I have the following issue when I try to set the xpath expression for a WAIT component. I use the properties panel and set PT10S as value of the expression. In the xml source code I obtain: <bpel:wait name="Wait">        <bpel:for><![CDATA[PT10S]]></bpel:for> </bpel:wait> instead that <bpel:wait name="Wait">         <bpel:for><![CDATA['PT10S']]></bpel:for> </bpel:wait> The value is not enclosed in the single quotes and when I run the process I obtain the following error: 18:00:31,620 ERROR [org.apache.ode.bpel.runtime.WAIT] (ODEServer-1) Fault while calculating due date: {http://docs.oasis-open.org/wsbpel/2.0/process/executable}invalidExpressionValue; Reason: Invalid duration: JBDS enviroment: Version: 7.1.1.GA Build id: GA-v20140314-2145-B688 BPEL Visual Designer: 1.0.3.v20130816-0854-CI Posted by forums Original post: https://developer.jboss.org/message/902937#902937
