Tomahawk is JSF, both Trinidad and Tomahawk are 3rd party JSF add-ons.
Hopefully aliasBean is moved over to myfaces commons someday as that
is a better home for it.
Without using alias bean or writing your own code to do the same.
Here is how to do it with no alias:
> first.jsp
> <tr:table id="tableId" value="#{backingBean.dataModel}" var="var">
> ... call second.jsp or something like that (like it was a
> component)
> </tr:table>
> second.jsp
> <tr:inputText id="textId" value="#{var.text}"/>
So that the var in the table maps to the same variable name in the included JSP.
Facelets has ui:param for its include, which has no equivalent in JSP.
This is why I strongly suggest that you use facelets and not JSP.
