Retrieve an object in a selectItem

[abaudouin]

Hi,

I use a SelectItem who contains a list of Object. For instance, it contains a list of Technology which are instance of a basic Java Class who implements Serializable.
My SelectItem doesn't interact with the server. It used only on client side.

The problem I have is to retrieve the technology selected in the selectItem when I submit the form. Using a LinkedHashMap<Technology, String> and set the selectItem with this LinkedHashMap doesn't work. I have te following Exception :

[ERROR] Uncaught exception escaped
java.lang.ClassCastException: fr.sii.nantes.b2m.client.transverse.ov.Technology
	at com.smartgwt.client.util.JSOHelper.convertMapToJavascriptObject(JSOHelper.java:645)

Is there a working solution to retrieve a selected object in a selectItem ?

Thanks

A valueMap must be a Map<String, String>. To provide a set of records and be able to retrieve the selected record, make a clientOnly DataSource and provide it as the optionDataSource on the SelectItem, and use getSelectedRecord() to get the selected record.
