Hello, I am unclear if the SCXML engine has problems with correct syntax for the <assign> tag or if I am misreading the W3C xsd for the <assign> tag. The W3C xsd specifies that the attributes of <assign> are "location", "src", and "expr". I notice that the examples in both the W3C site and SCXML Commons site use the attribute "name" instead of "location", which seems to be an error. For example, the microwave-02.xml example on the SCXML Commons site contains the following statement that apparently uses incorrect syntax:
<assign name="timer" expr="timer + 1"/> (Note also that the original examples on the W3C site all use the same apparently incorrect syntax). When I run on the SCXML Commons StandaloneJexlExpressions class using syntax following the W3C xsd, such as <assign location="timer" expr="timer + 1"/>, the following message is printed to the console: Feb 8, 2007 11:00:50 AM org.apache.commons.scxml.env.SimpleErrorReporter onError WARNING: EXPRESSION_ERROR (java.lang.ClassCastException: java.lang.Integer): When I change the statement to the apparently wrong syntax <assign name="timer" expr="timer+1"/> the state machine runs without error messages. Please clarify the correct attribute for the <assig> tag. Be aware that an scxml editing tool built using the Eclipse Modeling Framework and the W3C xsd file generates scxml that produces the error message noted earlier. My first impression is that the scxml editor built using the EMF produces the correct syntax for the <assign> tag. --David --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
