You probably are not returning correct startRow/endRow/totalRows values in your responses. Use the RPC tab in the Developer Console to see the requests and responses.

Thanks Iso,
We believe we are passing the parameters right.
Could it be the xml datasource? Look at that awful namespace for record tag:

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<response>
<status>0</status>
<startRow>0</startRow>
<endRow>10</endRow>
<totalRows>100</totalRows>
<data>
<record xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="sysObjectRecord">
<id>799</id>
<name>doc 0</name>

etc...
What do you think?
Thanks and regards.

Given that that's not valid XML (xsi prefix used without first declaring it), yes that's the problem - this is also clearly reported in the console.

Hi Isomorphic,

I don't know much about XML but, isn't "xsi" prefix declared by the expression xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" ?
That's what I suppose and what is said here: http://www.coderanch.com/t/128053/XM...xmlns-xsi-mean

That XML was generated by JAXB. Do you think JAXB generates invalid XML?

Thank you very much.

By the way, the live grid works with this XML. Here the "xsi" prefix is in the "value" tag.

Code:

<documentSearchResult totalRows="21" endRow="10" startRow="0">
  <objects>
    <object>
      <id>09019938800a70f4</id>
      <name>doc3</name>
      <type>m_revista</type>
      <properties>
        <entry>
          <key>r_object_type</key>
          <value xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema" xsi:type="xs:string">m_revista</value>
        </entry>
...

I think the problem are the attributes/namespaces in the "record path". Here the record path is "/documentSearchResult/objects/object". In my opinion this XML works because the record tag "object" doesn't have attributes/namespaces.

Thanks for your help.

Sorry, it's correct XML because the prefix is declared inline. However this puts the element in a different namespace, meaning the xpath used to select it has to have a matching namespace.

For simplicity, you should probably see if you can just avoid JAXB namespacing that element. Otherwise, you have Googling to learn about xpath and XML namespaces.

I think SmartGWT has a bug here because if you have this XML:

Code:

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<response>
  <status>0</status>
  <startRow>0</startRow>
  <endRow>10</endRow>
  <totalRows>100</totalRows>
  <data>
    <record xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="sysObjectRecord">
      <id>1</id>
      <name>doc 1</name>
    </record>
    <record xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="sysObjectRecord">
      <id>2</id>
      <name>doc 2</name>
    </record>
  </data>
</response>

then the XPath "/response/data/record" should be a valid record XPath for a DataSource. You can try it here: http://www.mizar.dk/XPath/Default.aspx

We don't need to include namespace information in the XPath as you say. Don't you think?

Ferran
