[a4j:actionparam] mapping from a javascript array to a bean

[pericoloso]

Hi everybody,

If I map a javascript String to a String property of my backing bean using <a4jactionparam>, there is no problem :

<script>
var titi = new Array();
titi[0] = 'creationDate';
titi[1] = 'comment';
</script>

<a4j:commandButton value="Apply">
 <a4j:actionparam noEscape="true" name="selection" value="titi[1]" assignTo="#{myBean.myString}" />
</a4j:commandButton>

The problem is that I want to map a javascript created array of String.
So I tried the same thing with a javascript Array :

<a4j:commandButton value="Apply">
 <a4j:actionparam noEscape="true" name="selection" value="titi" assignTo="#{myBean.myList}" />
</a4j:commandButton>

But I get a ClassCastException. I tried to use a List or a String[] for myList, but I allways get the same exception.
I think I could serialize my ajavascript Array and map it to my backing bean where convertion to a List or something else could be done, but it's a bit dirty and I'm pretty sure there is a good way to do this.
The problem is that I don't know what to search, so any track of solution would be appreciated :)

Did you manage to pass param "selection"? What was sent to the server with http request?

Once again, has anyone a solution for that problem? Serializing a javascript array and deserializing it in the bean isn't the nicest solution and would be appreciated when it is possible to have richfaces do that job.

Any ideas?
