Wicket SELECT doesn't update it's model -

i've wicket panel list of productviews (as select)

after choose productview select, load product database id of productview details form. can modify product entity , can save when finish.

after save try refresh select list update data, doesn't work(i mean, example, select contains old name of product after rename it, when select same productview, reload entity details form again, , of course new data appears database) don't want reload product list again, want solve memory. here source:

productview:

@entity @table(name = "product") @xmlrootelement public class productview implements serializable{          private static final long serialversionuid = 1l;         @id         @generatedvalue(strategy = generationtype.identity)         @basic(optional = false)         @column(name = "id")         private long id;         @column(name = "name")         private string name;         @enumerated(enumtype.ordinal)         @column(name = "category")         private category category;          public productview() {         }         public productview(long id) {             this.id = id;         }         public productview(product product) {             this.id = product.getid();             this.name = product.getname();             this.category = product.getcategory();         }         // + getters & setters     } 

product:

@entity @table(name = "product") @xmlrootelement public class product implements serializable {     // same productview more data, objects, connections, etc }

and html:

<select class="categoryselect" wicket:id="categoryselectcomponent">     <optgroup label="category one">         <wicket:container wicket:id="onecategory">                 <option wicket:id="option"></option>              </wicket:container>     </optgroup>     <optgroup label="category two">         <wicket:container wicket:id="twocategory">                     <option wicket:id="option"></option>             </wicket:container>     </optgroup>     <optgroup label="category three">         <wicket:container wicket:id="threecategory">                 <option wicket:id="option"></option>             </wicket:container>     </optgroup> </select> 

any idea?

call #setrecreatechoices(true) on selectoptions.
