[jboss-user] [JBoss Seam] - Re: Parameters not sent when using s:selectItems

[marius.oancea]

Now, I'm trying to allow multiselection. So I switched to h:selectManyListbox

In MarkupSearchCriteria:
	private Committee committee;
becomes 	private Committee committee[];

It seems now this fails:
   


Failure is:

Failure is in class "Pages" in method applyConvertedValidatedValuesToModel

Line that trigger the exception is                   valueExpression.setValue(object);


object is a string containing something like "[Lmymodel.Committee;@1afbdd4"

It seems that array cannot be user with "param" ?

Any solution to this? I found no example anywhere.
