Description Zuzana Krejčová 2012-04-17 15:12:03 UTC
Created attachment 578067 [details]
runtime error from server log

Description of problem:
In human tasks, we can use #{expression} to make the task properties dynamic. FreeMarker uses the same syntax for it's own purposes - namely "Numerical interpolation" (http://freemarker.sourceforge.net/docs/ref_depr_numerical_interpolation.html). 
When you use #{expression} in a human task in the Designer and generate task form templates there, the '#{expression}' is put directly into the form, as it is. Trying to use that form (for example in the jBPM Console) then results in an error in server log and http 500.

Version-Release number of selected component (if applicable):
BRMS 5.3.0 ER5

Steps to Reproduce:
1. Create a process in the Designer, perhaps like the example - Evaluation. The actorId for the self evaluation should be of the #{expression} form.
2. Save and click Generate Task Form Templates. Build the package.
3. In the Console, start the process and get to the human task. Try to view it.

Actual results:
HTTP error 500, runtime exception in server log.

Expected results:
Task form.

The process used is the Evaluation, the problematic part is the Self Evaluation task and PerformanceEvaluation-taskform, which contains the following lines (the other form is okay):

<div id="container">
	<div id="content">
            <legend>Task Info</legend>
            	<label for="name">Owners</label>
            	<div class="div_checkbox">

            	<label for="name">Actor ID</label>
            	<div class="div_checkbox"></div>
            	<label for="name">Group</label>
            	<div class="div_checkbox"></div>
            	<label for="name">Skippable</label>
            	<div class="div_checkbox">true</div>
            	<label for="name">Priority</label>
            	<div class="div_checkbox"></div>
            	<label for="name">Comment</label>
            	<div class="div_checkbox">Please perform a self-evalutation.</div>
            <div class="clear"></div>
