MarshalledContentWrapper錯誤JBPM

Question

其實我想這個鏈接，例如 https://community.jboss.org/people/bpmn2user/blog/2011/02/21/jbpm5-example-for-forms-with-variables

現在，當它被調用達到人工任務它顯示jsp頁面

Model Number: MarshalledContentWrapper{content=B@1e0d7c5, 
marshaller=org.drools.marshalling.impl.SerializablePlaceholderResolverStrategy, 
type=class java.lang.String} 
Quantity: MarshalledContentWrapper{content=[B@75ffe5, 
marshaller=org.drools.marshalling.impl.SerializablePlaceholderResolverStrategy,   
type=class java.lang.String} 
Priority: MarshalledContentWrapper{content=[B@f31cdb, 
marshaller=org.drools.marshalling.impl.SerializablePlaceholderResolverStrategy, 
type=class java.lang.String} 

，然後文本框在此FTL的文件並提交按鈕。

當我點擊提交

我在我的控制檯上得到這個輸出。

Human Task Started.... 
Exception in thread "Thread-2" java.lang.ClassCastException: java.lang.String cannot be cast to org.jbpm.task.utils.MarshalledContentWrapper 
      at org.jbpm.task.utils.ContentMarshallerHelper.unmarshall(ContentMarshallerHelper.java:157)

      at java.lang.Thread.run(Thread.java:679) 

如何解決這個問題有沒有人有這方面的想法。在我的BPMN的腳本任務

Answer 1

我已經寫了以下代碼文件

map = new java.util.HashMap(); 

map.put("priority","High"); 
map.put("modelNumber","1234"); 
map.put("quantity","225"); 

kcontext.setVariable("map", map);
