(Reusable) Dependent dropdowns in Seam and Richfaces

Published Thursday, May 7th, 2009 by AN

In the previous post I had some code to illustrate how I do dependent dropdowns with seam and richfaces. I cleaned it up to focus on the important stuff and I am not sure to which degree it compiles and runs. However, you may have noticed one thing that is certainly odd. Most of the operations are on the object named “vendormodelselector” which is described in the post. But the search action is on “searcher”. This is because I include the seam file on multiple pages with “ui:include” (xmlns:ui=”http://java.sun.com/jsf/facelets”). and with “ui:param” I can pass a different searcher object depending on the page. Like this

<ui:include src="vendormodelmenu.xhtml">
	<ui:param name="vendormodelheader" value="Appropriate header"/>
	<ui:param name="searcher" value="#{searcher_object_name}"/>
</ui:include>

Neat!
