Hey Alec,
Looking at small excerpts from a large file leaves too much to the
imagination. Can you create a minimal but complete page and component
that reproduces the problem?
It feels like there is a bad return type or something on one of the
methods in the chain, so having a complete non-working example would
make it easier to debug.
Here is my working example, I tried to make it close to what you are doing.
****************** myapp.pages.Start.java:
public class Start
{
public List<String> getStrings() {
List<String> strings = new ArrayList<String>();
strings.add("Hello");
strings.add("Goodbye");
return strings;
}
@SuppressWarnings("unchecked")
public List<MyMap> getMaps() {
List<MyMap> maps = new ArrayList<MyMap>();
MyMap map = new MyMap();
map.put(0, "Zero");
map.put(1, "One");
maps.add(map);
map = new MyMap();
map.put("horse", "buck");
map.put("goose", "egg");
maps.add(map);
return maps;
}
public String getSomethingStrange() {
return (String)getMaps().get(0).get(1);
}
}
****************** myapp.pages.Start.tml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";>
<t:layout t:strings="prop:strings" t:maps="prop:maps"
xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd";>
This is the body
</t:layout>
******************** myapp.components.Layout.java
public class Layout {
@Parameter
private List<String> _strings;
@Parameter
private List<MyMap> _maps;
public String getSomethingStrange() {
return (String)_maps.get(0).get(1);
}
public List<String> getStrings() {
return _strings;
}
public void setStrings(List<String> strings) {
_strings = strings;
}
public List<MyMap> getMaps() {
return _maps;
}
public void setMaps(List<MyMap> maps) {
_maps = maps;
}
}
******************** myapp.components.Layout.tml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";>
<html xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd";>
<body>
<p>Strange: ${somethingStrange}</p>
<div style="border: thin red solid;"><t:body /></div>
</body>
</html>
******************** MyMap.java (for completeness...)
package joshcan.test;
import java.util.TreeMap;
@SuppressWarnings("unchecked")
public class MyMap extends TreeMap {
@Override
public Object get(Object key) {
Object o = super.get(key);
return "my" + o.toString();
}
}
************* Rendered output (hand formatted for readability)
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";>
<html xmlns="http://www.w3.org/1999/xhtml";>
<head>
<link href="/assets/tapestry/default.css" rel="stylesheet" type="text/css">
</head>
<body>
<p>Strange: myOne</p>
<div style="border: thin red solid;">This is the body</div>
</body>
</html>
Hope that helps,
Josh
