Struts taglib autocomplete with custom jsp tags

In short, I wanted a way to skip writing labels whilst writing a struts <html:text...> tag. I wrote a custom tag which extended the struts tag, but overrode the doStartTag to take a parameter from the jsp and output <label>parameter</label> before the rest of the compiled html.

Unfortunately, in doing so, IntelliJ is no longer able to autocomplete object names whilst filling out the property field in the tag. Does anyone know how to make IntelliJ treat my custom tag the same was as the struts taglib tag?

Can provide more examples upon request.
