Hello,
We need to access the row index (iteration variable) when using a4j:repeat.
I noticed that a4j:repeat exposes the stateVar, which currently only exposes the SequenceRange. I patched this as follows:
public abstract class SequenceDataAdaptor extends UIDataAdaptor {
protected DataComponentState createComponentState() {
return new DataComponentState(){
public Range getRange() {
return new SequenceRange(getFirst(),getRows());
}
// added this new method
public int getRowIndex() {
return SequenceDataAdaptor.this.getRowIndex();
}
};
}
...
}
However, i cannot get at the row index value.
Take one: try to print the range -- it works
<a4j:repeat value="#{items}" var="item" stateVar="state">
<h:outputText value="#{state.range}"/>
</a4j:repeat>
output: org.ajax4jsf.model.SequenceRange@fb8c90
Take two: try to print an invalid property -- it is correctly not found on the anonymous inner class
<a4j:repeat value="#{items}" var="item" stateVar="state">
<h:outputText value="#{state.foo}"/>
</a4j:repeat>
output: javax.el.PropertyNotFoundException: /ajaxtest.xhtml @19,39 value="#{state.foo}": Property 'foo' not found on type org.ajax4jsf.component.SequenceDataAdaptor$1
Take three: try to print the row index. it seems to be resolved on the integer type, and not the anonymous inner class??
<a4j:repeat value="#{items}" var="item" stateVar="state">
<h:outputText value="#{state.rowIndex}"/>
</a4j:repeat>
output: javax.el.PropertyNotFoundException: /ajaxtest.xhtml @19,44 value="#{state.rowIndex}": Property 'rowIndex' not readable on type int
I wonder what's going on. Any ideas? Or any other solution to get at the currently iterated row index?
cheers,
Greg
