Hi!

I'm trying to display a list of elements in a form: options in one of my JSP, but if the validation finds any problem and the form must be refilled with the errors, I'm finding a problem to set the selected element in the form: options.

The entity for filling the form: options is this:

Code:
public class Researcher implements Serializable
{

     private Integer researcherID;
     ...
     private String signature;
}
In my case, the label for the options is attribute "signature", and doing this it works perfect:

Code:
<form:options items="${researcherList}" itemLabel="signature" itemValue="researcherID"/>
The problem appears when I submit the form, and a error appears after validation (this error is in other field, not related to this options). The selected value in the select is converted to entity through a PropertyEditor. The code for it:

Code:
public class ResearcherPropertyEditor extends PropertyEditorSupport
{

	private ResearcherService researcherService;
	
	public ResearcherPropertyEditor(ResearcherService researcherService)
	{
		this.researcherService = researcherService;
	}
	
	
	@Override
	public void setAsText(String text)
	{
		
		Researcher rese;
		
		try
		{
			rese = researcherService.getResearcher(new Integer(text));
			setValue(rese);
		} 
		catch (NumberFormatException e)
		{
			setValue(null);
		} 
		catch (InstanceNotFoundException e)
		{
			setValue(null);
		}

	}
		

	@Override
	public String getAsText() 
	{
		Researcher rese = (Researcher)getValue();
			
		if (rese == null)
			return "";
			
		return rese.getResearcherID().toString();
	}
After this... a error appears refilling the form, because Spring is trying to select the appropiate field in the form: options and uses the value to perfom equals operation in Researcher (watched in debug mode).

The solution is, perhaps, leaving as value the object represented in options, but I don't know the way to do that. Any idea to achieve this?

Thanks in advance
