setDynamicAttribute not being invoked

Hi there, I can't seem to get the setDynamicAttribute method to work properly. I can get the application to print out the options but not the attributes. Below is my code (note I've been playing with it by commenting and uncommenting parts) :


the jsp:


the tld:

As I said, I can get it all to work except printing out the size attribute, to do that I have to put "out.print(String.format(ATTR_TEMPLATE, "size", this.size));" into my code.

Can anyone see why the setDynamicAttribute method is not being called by the container?

Thanks
Dave

There's a typo here, it should be "dynamic-attributes".

Hi..

I have the same problem even after checking all typos.

I'm getting jasperexception at the line of tag invocation.

It says root cause as :
java.lang.NullPointerException
customtag.simpletag.TestTag.<init>(TestTag.java:20)
org.apache.jsp.JSP.SimpleTagTest_jsp._jspx_meth_t_005fTest_005f0(SimpleTagTest_jsp.java:96)


Can someone help ... What might went wrong..?
