InputText value attribute issue

Question

If I add this in outputText it works, but in inputText it throws currentRow returned null. Why?
value="#{bindings.MyIter.currentRow.dataProvider.city}"

Answer 1

<af:inputText> is an editable value holder component in contrast to <af:outputText> which is not, so I suspect that <af:inputText> accesses its value holder during the Apply Request Values phase (i.e. before the iterator is executed, when there is no current row yet), but <af:ouputText> accesses it as late as the Render Response phase (when the iterator has already been executed).
You should not reference directly the iterator binding in an <af:inputText>. You should create and reference an attribute value binding for the City attribute instead. So, create an attribute value binding for the City attribute in the pageDef and then use this binding in your <af:inputText>, for example
<tt>  <af:inputText value="#{bindings.City.inputValue}" ... ></tt>
As this value binding should be used in some other attributes of the <af:inputText> tag too, the simplest way to do everything is to go to the DataControl palette, to find the requested iterator and to drag-and-drop the City attribute on the JSF page as InputText. JDev will automatically do then everything for you.
