selectOneMenu problem
Hello together!
I have selectOneMenu. It worked great, but know I added a value if nothing is selected ("Unknown") and it doesn't work anymore.
My selectOneMenu looks like:
<h:selectOneMenu id="selectOneBloodGroup" value="#{person.bloodGroup}">
<f:selectItems value="#{person.bloodGroupArray}"/>
</h:selectOneMenu>
My bean (getter and setter):
public void setBloodGroup(String bloodGroupItem)
{
FacesContext context = FacesContext.getCurrentInstance();
Application application = context.getApplication();
Message message = (Message)application.getVariableResolver().resolveVariable(context, "message");
if(bloodGroupItem==null||bloodGroupItem.equals("")||bloodGroupItem.equals(message.getDropDownBloodGroupNoValue()))
this.bloodGroup="-1";
else this.bloodGroup=bloodGroupItem;
}
public String getBloodGroup()
{
if(this.bloodGroup==null || this.bloodGroup.equals("")||this.bloodGroup.equals("-1"))
{
FacesContext context = FacesContext.getCurrentInstance();
Application application = context.getApplication();
Message message = (Message)application.getVariableResolver().resolveVariable(context, "message");
return message.getDropDownBloodGroupNoValue();
}
else return bloodGroup;
}
And the error I get is:
