[Laszlo-user] Problems with remotecall and dataset outside canvas

[Daniel Garrido]

Here I am again, posting another question... I must say that my
experience with OpenLaszlo either makes me feel stupid or makes me
think there's still a lot of work around OpenLaszlo to be done... Hope
it's the first one, so that OpenLaszlo remains being a possibility to
my project.

I'm trying to find a way to do the following:

Create a class component, that will have a remotecall to a started
javarpc. That remotecall is supposed to map its returned value to a
dataset local to the class. Is that possible? I tried the following
code, but with no success.

<library>
	<class name="Component">
		<handler name="oninit">
			var dataset = new LzDataset(this, {
				name : "available_models"
			});
			
			this.getAvailableModels.invoke(['equipment']);
			Debug.write("Created component " + this.name);
		</handler>
		
		<datacombobox shownitems="6" defaulttext="Choose One..."
			itemdatapath="local:parent.available_models:/*" valuedatapath="name()">

			<handler name="onselected">
				Debug.write("Selected model " + this.getValue());
				canvas.configuration.selectModel.invoke(['equipment',
						this.getValue()]);
			</handler>
		</datacombobox>
		
		
		<remotecall name="getAvailableModels"
					dataobject="parent.available_models"
					funcname="getAvailableModelsOL"
					remotecontext="$once{canvas.configuration}" />
	</class>
</library>

I also tried another things like, instead of creating the dataset
locally to the class to put it into canvas, but still the remotecall
was not able to see the dataset.

I wonder if the only way to make this work, is to put both dataset and
remotecall into canvas...
