condition expression string is restricted to 255 character length if the process definition is persistent
---------------------------------------------------------------------------------------------------------

                 Key: JBPM-764
                 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
            Reporter: Hannes Stillerich
         Assigned To: Tom Baeyens


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.
