java.lang.IllegalArgumentException: Parameter modelObject cannot be null

[Sigmar Muuga]

Hello,
I am creating a form, my form has an instance variable:
private Organization organisation;

Also, organisation is initialized in constructor with new Organisation().

Now I am creating a TextField, that uses the propertyModel:
IModelOrganization m1 = new PropertyModelOrganization(organisation, 
entity.name);
TextFieldOrganization organisationName = new
TextFieldOrganization(organisationName, m1);
organisationName.setRequired(true);
add(organisationName);

But when I load the page, I get:
java.lang.IllegalArgumentException: Parameter modelObject cannot be null

I have read the docs and manuals about models etc, but this thing here is
really weird..

Is in entity the field name also initialized? Try to set it to the empty
String in the initialization of entity.

 Also, organisation is initialized in constructor with new
 Organisation().

Does this initialization happen before or after you create the model?

 java.lang.IllegalArgumentException: Parameter modelObject cannot be
 null

This error message indicates it happens after.

Ok, sorry, my bad. I did the initialization afterwards :(
Sometimes such mistakes just happen...
