Hi Anissa,
Did you try #{} or $attribute{}
i think this two should help...
I had worked with Lists once while trying for tables and was able to
debug it well with the use of dumpAttributes handler..
I am sending you the relevant piece of code
<!beforeCreate
createList(size="$int{0}" result=>$page{selectedRows})
/>
where
<sun:button..
<!command
setAttribute(key="aSelectedVal" value="anyvalue");
createMap(result=>$attribute{mapName});
mapPut(map="$attribute{mapName}" key="aVal" value="#{aSelectedVal}");
getList(list="#{selectedRows}" //Note
passing list here.. newEntry="$attribute{mapName}")
/**
* <p> This method prints all the List by appending .
* <p> Input value: "id" -- Type: <code>java.lang.String</code></p>
* <p> Input value: "required" -- Type:
<code>java.lang.String</code></p>
* @param context The HandlerContext.
*/
@Handler(id="getList",
input={
@HandlerInput(name="list", type=List.class, required=true),
@HandlerInput(name="newEntry", type=Object.class, required=true)
})
public static void getList(HandlerContext handlerCtx) {
List<Object> list = (List<Object>) handlerCtx.getInputValue("list");
Object newEntry = handlerCtx.getInputValue("newEntry");
if (list != null)
list.add(newEntry);
else {
list = new ArrayList<Object>();
list.add(newEntry);
list.add(newEntry);
}
}
HTH...
println and DumpAttributes helped me debug the whole processing much
clearly..
