Hi,

I want to wrap a ZK macro component into a jsp tag using ZK 3.6.3 pro and zuljsp version 1.0.0

I've followed the instructions on page http://www.zkoss.org/smalltalks/zuljsp/

I've created this class:
public class UploadComponentTag extends BranchTag {
@Override
protected Component newComponent(Class clazz) throws Exception {
return new UploadComponent();
}
}

And this tld:
<taglib>
<tlib-version>1.0</tlib-version>
<jsp-version>2.3</jsp-version>
<tag>
<name>UploadComponent</name>
<tag-class>nl.contentarchitects.module.upload.UploadComponent
</tag-class>
<body-content>scriptless</body-content>
<dynamic-attributes>true</dynamic-attributes>
<attribute>
<description>
If false, this tag is ignored. Default: true.
</description>
<name>if</name>
<required>false</required>
<rtexprvalue>true</rtexprvalue>
</attribute>
<attribute>
<description>
If true, this tag is ignored. Default: false.
</description>
<name>unless</name>
<required>false</required>
<rtexprvalue>true</rtexprvalue>
</attribute>
<attribute>
<description>
Default : Zul Component .
</description>
<name>use</name>
<required>false</required>
<rtexprvalue>true</rtexprvalue>
</attribute>
</tag>
</taglib>

I get this error:
org.apache.jasper.JasperException: /upload.jsp(13,0) The u:UploadComponent tag declares that it accepts dynamic attributes but does not implement the required interface

But I thought because I extend BranchTag the interface DynamicAttributes is already implemented by that one?

How to fix this?
