ServletException using html:link tag

Hi all,

I'm trying to create a link to an action using the Struts' html:link tag
like this:

<html:link action="getSearchResults" name="SearchActionForm"
scope="request">test2</html:link>

However when I load the jsp containing this l get the following
exception:

[ServletException
in:/WEB-INF/jsp/repository/collection-resource-search-results.jsp]
Cannot cast to Map for name=SearchActionForm property=null
scope=request' 

When I disable the link and print some debug output from the
requestscope I get this:

request:
SearchActionForm=DynaActionForm[dynaClass=SearchActionForm,formFilledOut
=true,ftsQuery=,typeMappingId=,metadataFields={docato-title=,docato-modi
fier=},includeSchemaMappings={IModule},id=0,collectionUri=]

So there is a bean called SearchActionForm in the requestscope from the
class DynaActionForm which has a getMap() method returning a
java.util.Map.

Can someone please tell me what's causing this ServletException? I'm
using Struts 1.1 on Tomcat 5.0.19

Thanks in advance,

Jeroen

 || property="map" to your html:link

I think the html:link looks for the getter of the property 'map' (getMap())
by default so this shouldn't be necessary, but if I do it anyway like this:

  <html:link action="getSearchResults" name="SearchActionForm"
scope="request" property="map">test2</html:link>

I get the following exception: 

[ServletException
in:/WEB-INF/jsp/repository/collection-resource-search-results.jsp] No getter
method for property map of bean SearchActionForm

Now I don't understand this as well because SearchActionForm is a
DynaValidatorForm which extends from DynaActionForm which has a getMap()
method, so that should be the getter for the property 'map', right?

regards,

Jeroen

If I'm understanding your problem and if you have a getMap() method in
SearchActionForm I think you need to add
property="map" to your html:link
