You can't use a method call as the left hand side operand in a constraint; thus<br> age.size() == 0<br>is not correct.<br><br>Do you really mean<br> age == "null"<br><br>Probably <br> ApplicationData( age == null || age == "" )<br>
is the right thing to do, provided that ApplicationData.age is a String.<br><font color="#888888"><br>-W</font><div><div></div><div class="h5"><br><br><div class="gmail_quote">On 25 March 2011 17:32, Benson Fung <span dir="ltr"><<a href="mailto:benson.redhat@gmail.com" target="_blank">benson.redhat@gmail.com</a>></span> wrote:<br>

<br>
I got the following rule problem.<br>
<br>
The rule is like :<br>
<br>
1. | rule "Rule1"<br>
2. | dialect "mvel"<br>
3. | when<br>
4. | ad : ApplicationData( age == "null" , age.size() == 0)<br>
5. | then<br>
6. | ad.setReturnMsg( "age should not be null or empty" );<br>
7. | end<br>
<br>
where setReturnMsg is a method of ApplicationData Fact();<br>
<br>
However, I got the validation error :<br>
<br>
[Rule1] [ERR 101] Line 4:49 no viable alternative at input ')' in rule<br>
"Rule1" in pattern ApplicationData<br>
[Rule1] [ERR 102] Line 4:51 mismatched input '==' expecting ')' in<br>
rule "Rule1" in pattern ApplicationData<br>
<br>
Please help what the problem is.<br>
<br>
<br>
Thanks<br>
