wicket auto refresh datatable caches values -

i using datatable inside panel , panel set autorefresh every 60 sec. panel occassionally seems pull values not passed object. using propertycolumn add columns data table. there way disable cache in wicket or data table specifically

i have webservice returns list of contacts. list passed panels below

in loadcontactpanel new contactpanel(viewpanel.getcontentpanelid() , getcontactlistmodel());

public imodel<list<contact>> getcontactlistmodel() {     list<contact> listofmodels = //get list webservice call     return new listmodel<>(listofmodels); } 

in contactpanel load panel called accordianpanel

the accordianpanel contains repeatingview

each repeatingview panel , in panel, adding defaultdatatable

the source of defaultdatatable contactdataprovider extends sortabledataprovider

this code of model method in contactdataprovider

@override public imodel<contact> model(final contact object) {      return new abstractreadonlymodel() {         private static final long serialversionuid = 1l;           @override         public object getobject() {                 return object;         }      }; } 

in situation, should converted loadabledetachablemodel. 1 returned webservice or 1 in contactdataprovider

maybe loading data model stored in memory. should use loadabledetachablemodel load data each time component rendered. not sure answers question provided few details, please show code.
