connecting form field to action
I don't understand how actions can read fields from an html form through the sitemap. I have a
text field in a form, i'd like to pass that field's value to an action which will eventually modify it and
return it to the sitemap. My action, sitemap, form can see each other and execute properly,
however the text field is not passed to the action. Is there something special i have to do to the
sitemap in order for this to happen?
here is the code:
in my html:
<form action="search_1.html" method="post" name="Search_Form">
<b>Search</b>
<input size="25" maxlength="100" name="search_string" type="text">
<input value="..." name="cocoon-action-Search" type="submit">
</form>
in my Sitemap:
<map:actions>
<map:action name="Search" src="Search"/>
</map:actions>
<map:match pattern="search_*.html">
<map:act type="Search">
<map:generate src="{proper_string}.xml"/>
</map:act>
<map:transform src="stylesheets/main.xsl"/>
<map:serialize/>
</map:match>
in my java (action):
import org.apache.avalon.framework.parameters.Parameters;
import org.apache.cocoon.acting.AbstractAction;
import java.util.Map;
import java.util.HashMap;
import org.apache.cocoon.environment.ObjectModelHelper;
import org.apache.cocoon.environment.Redirector;
import org.apache.cocoon.environment.Request;
import org.apache.cocoon.environment.SourceResolver;
import org.xml.sax.EntityResolver;
public class Search extends AbstractAction {
public Map act (Redirector redirector, SourceResolver resolver, Map objectModel,
String source, Parameters params) {
Request request = ObjectModelHelper.getRequest(objectModel);
Map sitemapParams = new HashMap();
sitemapParams.put("proper_string", request.getAttribute("search_string"));
return sitemapParams;
}
}

Who populated the attribute? (Hint: nobody, thus no value)
Do you really want getParameter here instead of attribute? (Hint: yes,
you really want getParameter here).
