Sorry, I misunderstood your question:
<canvas debug="true" width="1000" height="500">
<include href = "thelib.lzx" />
<datatest name="dt">
<datapointer xpath="local:listNames:/*"
ondata="testView.process()" />
</datatest>
<view name="testView">
<method name="process">
this.dataPointer = dt.listNames.getPointer();
dataPointer.setXPath('/records/name');
myText.setText(dataPointer.getNodeAttribute('firstname'));
</method>
<text name="myText" resize="true"/>
</view>
</canvas>
That way the dataset can be accessed by using a datapointer. By I don't know
how to set a datapath from outsite the 'dt' object to the local dataset.
Best,
Raju

Betreff: [Laszlo-user] accessing datasets within classes
How do I reference a dataset from the canvas when it's called from an
external class?
Here's a very simplified test case, running solo under OL3.2
The datatest.lzx class:
<library>
<class name = "datatest" extends = "node" />
<dataset name = "listNames" request = "true" type = "http" src =
"/names/records/" />
</class>
</library>
And the simplified canvas:
<canvas>
<include href = "../datatest.lzx" />
<datatest />
<view>
<datapath xpath = "listNames:/records/name" />
<text datapath = "@firstname" />
</view>
</canvas>
The debugger returns "could not find dataset for listNames."
What do I need to change for the dataset to be visible to the canvas?
Many thanks
