Andrew Kharchenko commented on MYFACES-985:
As I said, I've replaced this part of code in renderer:
for (Iterator iterator = children.iterator(); iterator.hasNext();) {
UIComponent child = (UIComponent) iterator.next();
if (child instanceof UIInputTestComponent) {
children.remove(child);
break;
}
}
UIInputTestComponent itc = (UIInputTestComponent)
context.getApplication().createComponent(UIInputTestComponent.COMPONENT_TYPE);
itc.setId(component.getId() + _id);
itc.setNeedChildren(false);
children.add(itc);
with this one:
boolean isPresent = false;
for (Iterator iterator = children.iterator(); iterator.hasNext();) {
UIComponent child = (UIComponent) iterator.next();
if (child instanceof UIInputTestComponent) {
isPresent = true;
break;
}
}
if (!isPresent) {
UIInputTestComponent itc = (UIInputTestComponent)
context.getApplication().createComponent(UIInputTestComponent.COMPONENT_TYPE);
itc.setId(component.getId() + _id);
itc.setNeedChildren(false);
children.add(itc);
}
but it still has the same effect :(

Project: MyFaces
Type: Bug
Components: Implementation
Environment: Tomcat 5.0
JDK 1.4
Reporter: Andrew Kharchenko
Assignee: Mathias Broekelmann
Attachments: UIData NPE Sample.rar
I've found incorrect UIData behaviour under MyFaces which produces
NullPointerException on runtime and which works fine under Sun implementation.
Here it is:
I have a custom component which is extentor from UIInput. This component has
UIPanel extentor component as child which is added to children list of
UIInput component on rendering.
For one's turn, UIPanel extentor has one more UIInput extentor component as
child which is added to children list of UIPanel component on rendering.
This component works fine standalone, but when it is added to UIData, I have
NPE on runtime. Here is the part of listing:
java.lang.NullPointerException
at
javax.faces.component.UIData.restoreDescendantComponentStates(UIData.java:223)

javax.faces.component.UIData.restoreDescendantComponentStates(UIData.java:235)

at
javax.faces.component.UIData.restoreDescendantComponentStates(UIData.java:235)
at javax.faces.component.UIData.setRowIndex(UIData.java:178)
I will also attach sample component's classes, definitions and test page if
it will be granted after issue creation.

The real component is a DateChooser which consists with text field, button and popup calendar. DateChooser is extended from UIInput and has popup panel (UIPanel extentor) as child. For one's turn, popup panel has Calendar (UIInput extentor) as child. That's all. In addition, I've tried to move children addition to component's constructor from component's renderer and it helped.
