url parameters

[turkishpirate]

Hi all. Can anybody help me with following task:
I have a page, which renders a list of some commodities. When user clicks on commodity title, i must redirect him to commodity details page.
But this page must be bookmarkable, so i need to put commodity ID in page url. How can i do this with seam?
And then, how can i retrieve this parameter from url to use them in db-query?

try putting an f:param inside the commandlink

you should be able to get it from the request parameter map through the faces context.

you might also want to search for "page parameter" and @RequestParameter in the docs.

Use Seam Page Parameters and the s:link tag:

In pages.xml you define a param tag for your commodity page:

<page view-id="/commodity.xhtml">
 <param name="commodityid" value="#{commodity.id}"
</page>

Now in your Commodity you need to define a public method to set the commodity id

public void setCommodityId(String id){
 this.id = id;
}

According to Seam Documentation, any s:link transparently includes the request parameters so you might consider it. I didn't use the tag before so I cannot help you here. Or, you can use the standard outputLink tag of JSF:

<h:outputLink value="/commodity.seam">
 <f:param name="commodityid" value="#{commodity.id}"/>
</h:commandLink>
