Hi,
There might be a simple solution to this problem, but I have not been able to find it. Here is the problem:
I have a Java Bean that returns an array of objects. I try to display the list using the xf:repeat in an xml file. Here's the bean, xml and sitemap entries:
------------------------------------------------------
Cocoon version 2.1 latest CVS files
-------------------------------------------------------
Notes: I have all log levels set to DEBUG. I haven't found any useful info listed in the log file.
-------------
start.xml
--------------
<?xml version="1.0" ?>
<document xmlns:xf="http://xml.apache.org/cocoon/xmlform/2002">
<xf:form id="form-feedback" view="start" action="">
<xf:caption>Dummy</xf:caption>
<xf:output ref="/dummys[2]"/> <!-- this works fine -->
<xf:repeat nodeset="/dummys"> <!-- this generates an exception. Please see exception below -->
<xf:output ref="."/>
</xf:repeat>
</xf:form>
</document>
----------
Bean
----------
public class RuleSetHelperBean
{
public RuleSetHelperBean()
{
dummys[0] = new String("blah1");
dummys[1] = new String("blah2");
}
public String[] getDummys()
{
return dummys;
}
public String getDummys(int idx)
{
return dummys[idx];
}
protected String dummys[] = new String[2];
}
--------------------------------------------------------------
Sitemap entries (relevant to this problem)
--------------------------------------------------------------
....
<map:action name="RuleSetAction" src="" logger="xmlform.sitemap.action.ruleset"/>
.....
<map:match pattern="ruleset*">
<map:act type="RuleSetAction">
<!-- XMLForm parameters for the AbstractXMLFormAction -->
<map:parameter name="xmlform-validator-schema-ns" value="http://www.ascc.net/xml/schematron"/>
<map:parameter name="xmlform-validator-schema" value="schematron/ruleset-xmlform-sch-report.xml"/>
<map:parameter name="xmlform-id" value="form-feedback"/>
<map:parameter name="xmlform-scope" value="session"/>
<map:parameter name="xmlform-model" value="com.test.RuleSetHelperBean"/>
