EL support in task
-------------------
Key: JBPM-2755
URL: https://jira.jboss.org/jira/browse/JBPM-2755
Project: jBPM
Issue Type: Feature Request
Security Level: Public (Everyone can see)
Affects Versions: jBPM 4.4
Reporter: henry donnell
Fix For: jBPM 4.4
it would be helpful to be able to use EL in the <description> tag of the (human)
task node.
This will allow to create dynamical task descriptions based on the process variables.
Example:
<task name="review_task">
<description>Review order nr.#{order.nr} from customer
#{order.customer.name}</description>
</task>
The main purpose is to make human task descriptions in the task list more readable and
user-friendly.
Because if you have 20 task instances of the same task and they are all called
"Review order from customer" it is really hard to see at a first glance which
task is related to which customer.

Ronald van Kuijk commented on JBPM-2755:
----------------------------------------
I created a small test to see if this works and it partly seems to... The expression is
being recognized but once it should be actually parse, an error is thrown:

Expression expression = Expression.create("#{pv}",
Expression.LANGUAGE_UEL);
ScriptExpression se = ((ScriptExpression) expression);
assertEquals("MyTest", se.evaluate(execution));
}
}
The first one (UEL_VALUE) works and the second (UEL) not. I cannot seem to find the reason
why there is no scripting engine. The way the second expression is constructed is the same
as is done for the description. So I tried changing this in the parser (UEL
->UEL_VALUE) and the description could be parsed to (full test of task with description
is attached)

I use Ronald's code to create a patch. After change LANGUAGE_UEL to
LANGUAGE_UEL_VALUE the testcase could run successfully, but this issue depended on
JBPM-1209, and that issue have last more than two years. I don't know when JBPM-1209
could finished, and whether it will affect this issue.
