---------------------------------------

Maybe if you get these complex expressions, it would be better look at JBoss Rules integration

>                 URL: http://jira.jboss.com/jira/browse/JBPM-764
>             Project: JBoss jBPM
>          Issue Type: Bug
>          Components: Core Engine
>    Affects Versions:  jBPM 3.1.2
>         Environment: Win XP SP2, JDK 1.5.0_06, JBoss4.0.3SP1, MySQL 5.0.18-nt-max

> The expression of a condition (in a decision node) gets cut up if it is too long (>255 characters), e.g.
>   <decision name="Check Prerequisition">
> 		<transition name="proceed" to="Planning State">
> 	</transition>  
>   	<transition name="rejected" to="Error State">
>  		<condition expression="#{(contextInstance.variables['isCLIaffected'] and !contextInstance.variables['CLI_OK']) or
> 			(contextInstance.variables['isCAaffected'] and !contextInstance.variables['CA_OK']) or
> 			(contextInstance.variables['isCMAaffected'] and !contextInstance.variables['CMA_OK']) or
> 			(contextInstance.variables['isREGENaffected'] and !contextInstance.variables['REGEN_OK']) or
> 			(contextInstance.variables['isSGSNaffected'] and !contextInstance.variables['SGSN_OK']) or
> 			(contextInstance.variables['isRNCaffected'] and !contextInstance.variables['RNC_OK'])}"/>
> 	</transition>    
>   </decision>
> Of course a org.jbpm.JbpmException occures (couldn't evaluate expression) which is cause by org.jbpm.jpdl.el.ELException: Encountered "<EOF>", expected one of [".", ">", "gt", .....
> But if the processdefinition doesn't get loaded from the db, in other words it is directly defined in the code, the expression string can be longer (in this case 539 characters) and the expression works fine.
