Subject Re: help with MethodFailedException in ognl.OgnlRuntime.callAppropriateMethod
Date Tue, 03 May 2011 01:27:53 GMT
Nope, my bad.  After a full refactor I get the same error.  Below are
snippets of the new code and most recently generated error.

Stack Trace excerpt:
2011-05-02 21:24:49,887 175361 ["http-bio-8080"-exec-7] WARN
com.opensymphony.xwork2.ognl.OgnlValueStack - Error setting expression
'tagId' with value '[Ljava.lang.String;@1e73e0d'
ognl.MethodFailedException: Method "setTagId" failed for object
org.robbins.flashcards.model.Tag@144dc7b [name='my tag' ]
[java.lang.NoSuchMethodException:
org.robbins.flashcards.model.Tag.setTagId([Ljava.lang.String;)]
	at ognl.OgnlRuntime.callAppropriateMethod(OgnlRuntime.java:1285)
	at ognl.OgnlRuntime.setMethodValue(OgnlRuntime.java:1474)

JSP excerpt:
<s:form action="saveOrUpdateTag" method="post">
	<s:hidden name="tagId" />
	<s:textfield name="name" key="label.tag.name" size="20" />
	<s:submit label="label.flashcard.submit" align="center" />
</s:form>

POJO excerpt:
public class Tag  implements java.io.Serializable {


     private int tagId;

    public int getTagId() {
        return this.tagId;
    }

    public void setTagId(int tagId) {
        this.tagId = tagId;
    }
