JasperException when trying to pass non-String custom taglib attribute.

[Sean Stephens]

cross posting from jsp forum because its a Tomcat error.

I'm using a custom taglib with an attribute. When I try to refer to the attribute in the tag, then I get an error of type:

org.apache.jasper.JasperException: jsp.error.beans.property.conversion
org.apache.jasper.runtime.JspRuntimeLibrary.getValueFromPropertyEditorManager(JspRuntimeLibrary.java:885)
org.apache.jsp.content.includes.treetest_jsp._jspx_meth_odin_showNavTree_0(treetest_jsp.java:148)

Sean, cross-posting is against Ranch policy. It wastes people's time when multiple redundant conversations take place. If I had felt that your question was Tomcat-specific, I would have moved it here accordingly.

Please continue any discussion in the JSP forum (where I have answered your question).
