multiple selectOneMenus ->

[rwijeyra]

hi, i have a problem since im generating form fields dynamically.

i have a hashmap in a sessionbean: HashMap<String, List\<myObject\>>

in the view i'm iterating through the hashkeys using <ui:repeat> and displaying the elements of the list in a selectbox. like this:

<ui:repeat value="#{myHashMap.keySet}" var="key">
 <h:selectOneMenu id="selector" value="????" converter="#{myConverter}">
 <s:selectItems value="#{myHashMap.get(key)}" var="object" label="#{object.name}" />
 <a4j:support event="onchange" action="#{??bean.someaction??}" reRender="contentOfSelection" />
 </h:selectOneMenu>
 <h:panelGroup id="contentOfSelection">
 --- diplay content of selection ---
 </h:panelGroup>
</ui:repeat>

my question is now where and how to store the selected item, first i just thought i could have a single myObject property as selection, but of course that doesn't work since i'll have several selections.

it would be perfect if i could have another hashmap as selection, kind of like HashMap<String, myObject>

any ideas?

ok, i managed to handle the selection. by using a new class as hashmap value containing the list and a selection

HashMap<String, ListSelectorObject>

..........

class ListSelectorObject {
 MyObject selection;
 List<MyObject> list;
}

but now i have a new problem: jsf lifecycle. remember i want to display the content of the selection under the selectbox, as soon as i select something new. so i add a4j:support to the selectonemenu.

but now i have the problem, when i change the value, the form gets validatet (it contains some fields that have to be) , i could use immediate=true but then the model doesn't get updatet and the new values arent displayed.

any ideas?
