Another newbie situation :-) I get an exception on resume(). It is noted in
following code as a comment. The classes PrintTrue and PrintFalse exist, code
also below. As expected, the workflow suspends ... waiting for input. But when
provided the input via resume(), it throws exception ...
Understanding this will probably get me on the path to hvaing a clue :-) Any
help greatly appreciated.
<?php
require_once 'lib/ezComponents/Base/src/base.php ';
require_once 'lib/ezComponents/Database/src/factory.php ';
require_once 'PrintTrue.php';
require_once 'PrintFalse.php';
function __autoload ( $className )
{
ezcBase :: autoload ( $className );
}
$dbparams = array(
'type' => 'mysql',
'dbname' => 'wflow',
'user' => 'root',
'pass' => 'password' );
$workflow = new ezcWorkflow('Test');
$input = new ezcWorkflowNodeInput(array ('choice' => new
ezcWorkflowConditionIsBool));
$workflow->startNode->addOutNode($input);
$true = new ezcWorkflowNodeAction('PrintTrue');
$false = new ezcWorkflowNodeAction('PrintFalse');
$branch = new ezcWorkflowNodeExclusiveChoice();
$branch->addConditionalOutNode(new ezcWorkflowConditionIsTrue('choice'),$true);
$branch->addConditionalOutNode(new
ezcWorkflowConditionIsFalse('choice'),$false);
$input->addOutNode($branch);
$merge = new ezcWorkflowNodeSimpleMerge();
$merge->addInNode($true)->addInNode($false)->addOutNode($workflow->endNode);
$db = ezcDbFactory::create($dbparams);
$definition = new ezcWorkflowDatabaseDefinitionStorage($db);
$definition->save($workflow);
$execute = new ezcWorkflowDatabaseExecution($db);
$execute->workflow = $workflow;
$executionId = $execute->start();
$execute = new ezcWorkflowDatabaseExecution($db, $executionId);
// Throws following exception at the resume() ...
ezcWorkflowExecutionException: Node activates less conditional outgoing nodes
than required.
$execute->resume(array('choice' =>true));
