conditional flow expressions

valarmathi — Mon, 29 Oct 2012 09:00:30 GMT

Hi,I have created conditional flow expressions example.this is my xml file <?xml version="1.0" encoding="UTF-8"?><definitions xmlns="http://www.omg.org/spec/BPMN/20100524/MODEL" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:activiti="http://activiti.org/bpmn" xmlns:bpmndi="htt

1) Why are you running unit-tests in a tomcat?
2) The xml-file is not on the class path on the given location. If it was, you wouldn't see this:

EXCEPTION: org.activiti.engine.ActivitiException: resource 'org/activiti/examples/bpmn/expression/UelExpressionTest.testValueAndMethodExpression.bpmn20.xml' not found

Hi,

I changed the xml file forthe corresponding path,but i get the different error

Please don't just paste any stack trace you encounter in the forum and expect people to fix you're problem. Please read the stack trace yourself first.. It clearly says:


no processes deployed with key 'UelExpressionTest.testValueAndMethodExpression'

So look into your bpmn20.xml file and see what the process-ID is…

Hi,

I used to change the process id,previously i didnt noticied it .

Cause: org.activiti.engine.ActivitiException: Unknown property used in expression

You are referencing a variable in your expression which isn't a process variable.

Re: conditional flow expressions

valarmathi — Fri, 02 Nov 2012 08:54:51 GMT

Hi ,

I used these two variables in the sequence flow

<sequenceFlow id="flow3" name="${order.isPremiumOrder}" sourceRef="exclusiveGw" targetRef="premiumService">
<conditionExpression xsi:type="tFormalExpression"><![CDATA[${order.isPremiumOrder}]]></conditionExpression>
</sequenceFlow>
<sequenceFlow id="flow2" name="${order.price<=250}" sourceRef="exclusiveGw" targetRef="standardService">
<conditionExpression xsi:type="tFormalExpression"><![CDATA[${order.price <= 250}]]></conditionExpression>
</sequenceFlow>

but i didnt mention these variables in the process,mentioned in he java class itself.

Thanks,
Valarmathi P

Re: conditional flow expressions

jbarrez — Mon, 05 Nov 2012 07:51:13 GMT

I see… Hmm, as far as I see the process, that should just work. You've added the 'order' object in the map you provide on process instance start, so that's good.

Can you add a service task in between en write out the order value? Can the variable be found there?

Re: conditional flow expressions

valarmathi — Mon, 05 Nov 2012 08:29:48 GMT

That's the problem,order value not found anywhere in the process.I thought i need to mention the order value,but i don't know where i can declare it.Please tell me.

Thanks,
Valarmathi P

Re: conditional flow expressions

frederikherema1 — Mon, 05 Nov 2012 11:13:25 GMT

HOW do you place the order variable on the process in the first place? You said using Java…

Re: conditional flow expressions

valarmathi — Tue, 06 Nov 2012 05:06:57 GMT

Hello,

In java we declared a variable in the same class itself(if not using POJO classes means).
I asked activiti class ,in the activiti class itself i have declared the variables frm the same class.

Thanks
Valarmathi
