remotebutton example. The exception is as follows -

to TLD or attribute directive in tag file, attribute src does not accept any
expressions

The offending JSP code is -
<sx:submit type="image" label="Alt Text" targets="t1"
src="${pageContext.request.contextPath}/images/struts-power.gif"
href="%{ajaxTest}" />
The generated TLD file indicates that expressions should not be evaluated in
the src attribute. I will attach a patch which would fix the issue.
