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 :(

> Key: MYFACES-985
> URL: http://issues.apache.org/jira/browse/MYFACES-985
> 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)
> at
> javax.faces.component.UIData.restoreDescendantComponentStates(UIData.java:235)
> at
> 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.
