Hi Harald,
While running in development mode, It works fine in IE7 but again gives the
same exception in chrome.
Any solution ?
Could u pls let me know the concept of writing XPath with XMLfield. i mean
wat would be XPath for a particular xmlfield according to xml ?
As for example :
<Buses>
<Bus>
<Type>BusType</Type>
<PickUpPointOptions>
<Option>
<Sequence>pickupSequence </Sequence>
<Desc>pickupPoint</Desc>
</Option>
..
..
</PickUpPointOptions>
<Fare>fare</Fare>
</Bus>
<Bus>
-----
</Bus>
</Buses>
For the above xml, I have
*
public* *class* Buses {
*public* *interface* BusesReader *extends* XmlReader<Buses> {}
*public* *static* *final* BusesReader *XML* = GWT.*create*(BusesReader.*
class*);
@XmlField("//Bus") List<Bus> listOfBus;
}
public class Bus {
public interface BusReader extends XmlReader<Bus> {}
public static final BusReader XML = GWT.create(BusReader.class);
@XmlField String Type;
@XmlField("//PickUpPointOptions") List<Option> PickUpPointOptions;
@XmlField String Fare;
}
public class Option {
public interface OptionReader extends XmlReader<Option> {}
public static final OptionReader XML = GWT.create(OptionReader.class);
@XmlField int Sequence;
@XmlField String Desc;
}
Am i providing the correct XPath at proper places ?
Using this, I am able to get the list<Bus> and from this Bus object i get
List<Option> properly but i am not able to read values from Option class. It
always gives null for Desc and 0 for Sequence.
Pls suggest.
Thanks
Deepak
