Iterating a map in template
Hi,
I'm trying to iterate a map in template with following code, but, it turns
out that the entire map is only one row, I'm sure I have made something
wrong, can anybody point it out? Thanks,
template:
<t:loop source="counts" value="count">
<p>${count}</p>
</t:loop>
code:
@Property
private Map<Integer, String> count;
@Cached
public Map<Integer, String> getCounts() {
return cnts;
}
private static TreeMap<Integer, String> cnts = new TreeMap<Integer,
String>();
static {
cnts.put(1, "ITEM1");
cnts.put(2, "ITEM2");
}

I don't understand. Your loop source and value are both the same type?
The way you have this setup, it won't work. You should consider setting
your source to the keyset of the map, and provide properties in your class
that return the value based on the current key.

Try this (untested):
-----
<t:loop source="entries" value="entry">
<p>${entry.key}: ${entry.value}</p>
</t:loop>
@Property
private Map.Entry<Integer, String> entry;
public Set<Map.Entry<Integer, String>> getEntries() {
return cnts.entrySet;
}
-----

I expect count to be of type MapEntry or in case getCounts() returns cnts.values() instead it has to be of type string?
