Find Conversations not working

[girishghoda57]

Hi team @serious6 @OS-JaR @pkropachev @shibd @atamer,
We used ews java api : <ews.java.api.version>2.1-SNAPSHOT</ews.java.api.version>

We call below code
Collection<Conversation> folderConversations = exchangeService.findConversation( new ConversationIndexedItemView(10), new FolderId(WellKnownFolderName.Inbox));

But its threw below error
The request failed. The expected XML node type was END_ELEMENT, but the actual type is START_ELEMENT.

Please help, we stuck on two days.
Thank you

For any of user need help on it. The posted solution below:

1. First replace FindConversationResponse.java with below code

  List conversations = new ArrayList();
  List highlightTerms = new ArrayList();
  int totalCount;

/**

  public FindConversationResponse() {
  super();
  }

/**

reader.readStartElement(XmlNamespace.Messages,
    XmlElementNames.Conversations);
if (!reader.isEmptyElement()) {
  do {
    reader.read();
    if (reader.getNodeType().getNodeType() == XmlNodeType.START_ELEMENT) {
      Conversation item = EwsUtilities.
          createEwsObjectFromXmlElementName(Conversation.class,
              reader.getService(), reader.getLocalName());

      if (item == null) {
        reader.skipCurrentElement();

        item.loadFromXml(

        {
            HighlightTerm term = new HighlightTerm();

            term.loadFromXml(
                reader,

{
	this.totalCount = Integer.parseInt(reader.readElementValue());
	reader.read();
}

}
}
`

2. Create file name "HighlightTerm" in package microsoft.exchange.webservices.data.property.complex and paste below code:
   `package microsoft.exchange.webservices.data.property.complex;

import microsoft.exchange.webservices.data.core.EwsServiceXmlReader;
import microsoft.exchange.webservices.data.core.XmlElementNames;

public class HighlightTerm extends ComplexProperty {

private String scope;

private String value;

public HighlightTerm() {
	
}


/**

• Tries to read element from XML.
• @param reader The reader.
• @return true, if successful
• @throws Exception the exception
  */
  @OverRide
  public boolean tryReadElementFromXml(EwsServiceXmlReader reader)
  throws Exception {

if (reader.getLocalName().equals(XmlElementNames.HighlightTermScope)) {
  this.scope = reader.readElementValue();
  return true;
} else if (reader.getLocalName().equals(XmlElementNames.HighlightTermValue)) {
  this.value = reader.readElementValue();
  return true;
} else {
  return false;
}

}

}`

3. Add extra properties name in XmlElementNames.java
   public static final String HighlightTerms = "HighlightTerms"; public static final String HighlightTerm = "Term"; public static final String HighlightTermScope = "Scope"; public static final String HighlightTermValue = "Value"; public static final String TotalConversationsInView = "TotalConversationsInView"; public static final String IndexedOffset = "IndexedOffset";

It resolves "The request failed. The expected XML node type was END_ELEMENT, but the actual type is START_ELEMENT." error for findConversation().

I got this solution from .NET repository.
Thank you.
