Hi,
I have been playing with your suggestions...
the xml-rpc function returns this XML (according to debug.write()..))
<element><item><item>1</item><item>Test
Project</item></item><item><item>2</item><item>Ries test
project</item></item><item><item>3</item><item>Klaas test
project</item></item></element>
And currently My laszlo application looks like this:
<?xml version="1.0" encoding="UTF-8" ?>
<canvas width="800" height="350">
<dataset name="me"><thedata /></dataset>
<datapointer name="dp" xpath="me:/"/>
<xmlrpc name="sqlSelect" service="http://127.0.0.1/~rvt/antshill/";>
<handler name="onload">
Debug.write('meerkat XML-RPC service loaded');
Debug.write('proxy:');
Debug.inspect(this.proxy);
</handler>
<handler name="ondata" args="retval">
var el = LzDataElement.valueToElement(retval);
Debug.write(el.serialize());
element = dp.xpathQuery("thedata")
element.appendChild (LzDataElement.valueToElement(retval))
</handler>
<handler name="onerror" args="error">
Debug.write('onerror:', error);
</handler>
<remotecall name="gc" funcname="sql.select">
<param value="'select * from projects'" />
</remotecall>
</xmlrpc>
<window x="20" y="20" width="200" height="250" title="Simple Window"
resizable="true">
<simplelayout axis="y" spacing="10"/>
<grid name="testGrid" datapath="me">
<gridtext editable="false" datapath="@id" datatype="number">uid
</gridtext>
<gridtext datapath="@displayname" width="200">Project
</gridtext>
</grid>
<button>
Retreive Data
<handler name="onclick" method="redify"/>
<method name="redify">sqlSelect.gc.invoke()</method>
</button>
</window>
</canvas>
The whole system doesn't return me any error but:
I have the following questions:
1) Is XML-RPC a good solution for CRUD operations on a database?
2) What could be wrong with the above, my grid doesn't get filled.
I know my datapath for gridtext is wrong, but I also don't have a clue
where to set it to:
In PHP I would just call xml2array().. and voila I am there....
However in laszlo that will properly works different.
Is the XML returned correctly? (it is generated by the PHP XML-RPC library).
