FormTester and Ajax
Hello,
I need some help with FormTester and Ajax.I want to test a form, in which the second dropdown is updated in ajax when we change the first dropdown.The form is working fine but I can't manage to test it.
DropDownChoice<Company> companyDropDownChoice = new DropDownChoice<>( "company", LoadableDetachableModel.of( ()-> getCompaniesList() ), new CompanyChoiceRenderer<>() );managerDropDownChoice.setRequired( true );form.add( companyDropDownChoice );
DropDownChoice<User> managerDropDownChoice = new DropDownChoice<>( "manager", LoadableDetachableModel.of( () -> getUserList(companyDropDownChoice.getConvertedInput()) ), new UserChoiceRenderer<>() );managerDropDownChoice.setRequired( true );form.add( managerDropDownChoice );
companyDropDownChoice.add( new AjaxFormComponentUpdatingBehavior( "change" ) { @Override protected void onUpdate(AjaxRequestTarget target) { target.add( managerDropDownChoice ); }} );
//testFormTester formTester = tester.newFormTester( "form" );formTester.select( "company", 0 );tester.executeBehavior( (AbstractAjaxBehavior) tester.getComponentFromLastRenderedPage( "form:company" ).getBehaviors().get( 0 ) );formTester.select( "manager", 0 ); // Throws java.lang.IndexOutOfBoundsException: Index 0 out-of-bounds for length 0
Of course I made sure that for the company at index 0, getUserList() returns some items.Also, I made sure that when calling tester.executeBehavior, getCompaniesList() is indeed called. It's more like if formTester does not update the dropdown...
What am I missing?
Thanks in advance,Virginie

Hi,
FormTest#select() sets the value of that component into the request
*and* submits it - the request is then *cleared* for the upcoming request.
Thus when you call #executeBehavior() afterwards, the request will be
completely empty and no company is select.
You will have to set the value of that component once again.
Have fun
Sven
