exclusive gateway problem - choice do not works

[larry]

Hi all,

I begin to use Activiti and I sketched the simplest work-flow containing a gateway (see file at the end of the message).
It doesn't work.
Within the JUnit test in Eclipse, everything works well, but in the Activity Explorer, I have an error:
- either "no outgoing sequence flow" if I place the values to compare, within simple/double quotes.
- or "unknown property used in expression" if I do not use quotes.

The environment I use is:
- Operating system : Linux Fedora 23 - 64 bits
- Java Oracle 1.8.65 - 64 bit
- Eclipse Juno - 64 bit
- Apache Tomcat 8 - 64 bit
- Activiti 5.18

Please tell me what do I do wrongly.
Thank you in advance for your help.

Hi Larry,

do you have `choix` variable set in your activiti-explorer process instance?

Martin

Hi Martin,

Thank you for your answer.
I suppose the variable "choix" is initialized automatically within the activiti-explorer process instance.

I declare this variable within a form:
<code>
<activiti:formProperty id="choix" name="Choix" type="enum" required="true">
</code>
… and I find that (I quote from "https://forums.activiti.org/content/how-store-and-retrieve-process-instance-variable-values-explorer..."):
"All form values are stored as process variables, so putting them on the form automatically makes it a process variable."

Isn't that right?

Hi Larry,

What is the value of choix variable?

Hi all,

I figured it, eventually.
The problem was … that I used to deploy a process via "Processes"->"Model workspace"->"Import", then "Deploy".
It doesn't work, I do not know why.

Today I successfully deployed my first workflow and it works like a charm.
I did that via "Manage"->"Deployments"->"Upload New".

So, case closed … unless someone can explain me why it works the second way and not the first.
