Errors with rendering feedback labels on a form during unit
testing. Works fine when viewed from the browser.
Hi all,
I'm getting some strange behavior from my tests. I have an abstract
class that all ajax feedback forms inherit from. BaseFeedBackForm
http://pastebin.com/NWALFWvi
I have this test code
http://pastebin.com/zZyzG1e6
What's happening is my onBeforeRender of my BaseFeedbackForm is being
invoked twice. The first time it is invoked is by this line of code in
my test.
tester.startPage(HomePage.class);
This visits all the form components, and decorates all components except
buttons with a FormFeedBacklabel. A label I'm using to display
validation errors when the input is incorrect onblur. This works well
when the form is created both in my unit test and when rendered via a
browser. However, when this is invoked.
registerForm.submit();
My page is re-rendered, which is throwing the error
org.apache.wicket.WicketRuntimeException: Error attaching this container

Should I not be using onBeforeRender in this way, and instead using a
listener for when the components are added to the form? I'm new to
wicket, so any help would be greatly appreciated.
thanks,
Todd

Posted by Igor Vaynberg <ig...@gmail.com>.
onbeforerender is called before every render, so the second render
that is invoked after onsubmit() is running onbeforerender() again and
adding duplicate components. your visitor should check if the
component it is trying to add already exists using component#get(id)
