restful search using param

[vdeminico]

Hi,
I have a question about the use of f:param attribute to build a restful url. The scenario is simple. I have a suggestionbox seam component for autocompletion. It's a search textfield. When I submit a request, I'd want to build a restful request based on the data selected on the suggestionbox component.

The home.xhtml fragment is:

<h:form>
              <h:outputLabel value="#{messages['home.label.searchText']}" for="searchText" />
              <h:inputText id="searchText" 
                        value="#{searchTextAction.selectedSearchItem}"
                         converter="#{searchItemConverter}"/>
              <rich:suggestionbox id="searchSuggestionbox"
                    for="searchText" var="item" fetchValue="#{item.nome}"
                    suggestionAction="#{searchTextAction.suggestSearchItems}"
                    minChars="2" value="#{searchTextAction.selectedSearchItem}" height="300" width="200">
                    <h:column>
                         <h:outputText value="#{item.searchItemText}" />
                    </h:column>
               </rich:suggestionbox>
               
               <s:link value="Cerca" view="/search.xhtml">
                    <f:param name="prefix" value="bedandbreakfast"/>
                    <f:param name="sid" value="#{searchTextAction.selectedSearchItem.sid}"/>
                    <f:param name="suffix" value="#{searchTextAction.selectedSearchItem.url}"/>
               </s:link>
          </h:form>

when the user submit the form through s:link, it creates a GET request and, as expected, it appends the three params to the URL. Obviously it can't retrieve values for param sid and suffix because they are calculated on the server. There is a solution to this problem????

Thanks,
Valerio.

Valerio, you cannot submit form data using s:link.

I have only recently started understanding this myself.  Here you might find a good explanation.

I think you want to use h:commandLink to submit the input.  Then in search.page.xml you want to wire your parameters to the searchTextAction bean like this

<param name="prefix" value="bedandbreakfast"/>
<param name="sid" value="#{searchTextAction.selectedSearchItem.sid}"/>
<param name="suffix" value="#{searchTextAction.selectedSearchItem.url}"/>

These parameters will get set before search.xhtml is rendered and will result in a URL somewhat like this

search.seam?prefix=bedandbreakfast&sid=<searchTextAction.selectedSearchItem.sid here>&suffix=<searchTextAction.selectedSearchItem.url here>

Ok, thanks for your reply Tanya.
Now I have an url like this:

search.seam?regione=CAMPANIA&provincia=BENEVENTO&comune=APOLLOSA&cid=9

I'd want a restful url, like

/prefix/CAMPANIA/BENEVENTO/APOLLOSA

Normally I do it using the seam (third part) url rewrite filter, but now it doesn't work. This behaviour is correct, because the filter acts before the jsf one. For me it's impossible to solve the problem without using an explicit re-rendering.

Any ideas?

Valerio.
