> The AbstractControl javadoc says: "Subclasses are expected to at least override getTag()  to differentiate the control.". What it *also* should mention, is that it needs a default constructor if you have created a custom constructor. 
> At deploy time, all the controls listed in click.xml will have their onDeploy() method called. But the reflection part will fail if the default cstor does not exist.
> org.apache.click.service.XmlConfigService.deployControls(XmlConfigService.java:1077):
>        Class deployClass = ClickUtils.classForName(classname);
>        Control control = (Control) deployClass.newInstance();  //<--- fails at deploy time
>        control.onDeploy(servletContext);
