[jbpm-issues] [JBoss JIRA] Commented: (JBPM-2755) EL support in task's <description> tag

[ https://jira.jboss.org/jira/browse/JBPM-2755?page=com.atlassian.jira.plug... ] 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: org.jbpm.api.JbpmException: no scripting engine configured for language uel at org.jbpm.pvm.internal.script.ScriptManager.evaluate(ScriptManager.java:111) at org.jbpm.pvm.internal.script.ScriptManager.evaluateExpression(ScriptManager.java:88) at org.jbpm.pvm.internal.el.ScriptExpression.evaluateInScope(ScriptExpression.java:45) at org.jbpm.pvm.internal.el.Expression.evaluate(Expression.java:102) at org.jbpm.pvm.internal.expr.UelExpressionTest.testUelExpression(UelExpressionTest.java:56) Testcase: import org.jbpm.pvm.activities.WaitState; import org.jbpm.pvm.internal.builder.ProcessDefinitionBuilder; import org.jbpm.pvm.internal.el.Expression; import org.jbpm.pvm.internal.el.ScriptExpression; import org.jbpm.pvm.internal.el.UelValueExpression; import org.jbpm.pvm.internal.model.ExecutionImpl; import org.jbpm.test.JbpmTestCase; public class ExpressionTest extends JbpmTestCase { public void testUelExpression() { ExecutionImpl execution = (ExecutionImpl) ProcessDefinitionBuilder .startProcess() .startActivity("initial", new WaitState()) .initial() .endActivity() .endProcess() .startProcessInstance(); execution.setVariable("pv", "MyTest"); Expression expression = Expression.create("#{pv}", Expression.LANGUAGE_UEL_VALUE); UelValueExpression uve = ((UelValueExpression) expression); assertEquals("MyTest", uve.evaluate(execution)); 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) Index: src/main/java/org/jbpm/jpdl/internal/xml/JpdlParser.java =================================================================== --- src/main/java/org/jbpm/jpdl/internal/xml/JpdlParser.java (revision 6150) +++ src/main/java/org/jbpm/jpdl/internal/xml/JpdlParser.java (working copy) @@ -493,7 +493,7 @@ Element descriptionElement = XmlUtil.element(element, "description"); if (descriptionElement!=null) { String descriptionText = XmlUtil.getContentText(descriptionElement); - Expression descriptionExpression = Expression.create(descriptionText, Expression.LANGUAGE_UEL); + Expression descriptionExpression = Expression.create(descriptionText, Expression.LANGUAGE_UEL_VALUE); assignableDefinition.setDescription(descriptionExpression); } Fixes the problem...
