the previously mentioned scrollbar flashing bug was caused by the an old style sheet that had been included. i wiped out the style sheet and now it's fine.

The easy solution to this would be to specify a DTD, as has been requested before. I don't believe this stops you from extending it, but warnings and auto-complete would then work for the standard stuff.

Sorry, because the format is extensible, we can't tell the difference between typos vs new properties you're adding.

By the way, is there a log level I can turn on to spot XML errors? I've had things mis-spelled before and they are difficult to spot.

the twitchy scrollbar syndrome is happening with that example in the regular theme now as well.

it goes away when i resize the browser and it starts when i hit a button and a dialog window appears then disappers.

Also, I just checked, that scrollbar appearing-disappearing quickly bug (happens after you click a button in the example above), does not appear in the default theme.

It's pretty bad in the TreeFrog theme though... epileptic.

It's required unless the only valid operation is "fetch".

By the way, is it necessary for each DataSource to have a primary key? My guess was yes, or else the data-bound components won't know what to index each record with.

Excellent. It works. Thank you for going through that with me. Note that the documentation I posed originally is wrong on a few counts, so please put a bug against that.

In general, it would be nice if the examples in the manual can include the full file instead of small excerpts. If something is to be highlighted, use bold. Or include the full example at the end of each section.

Here's the working DataSource definition.

Code:

<DataSource ID="dmiMethod_DataSource" serverType="generic" schemaBean="com.sample.data.MyResultClass"> <fields> <field name="id" type="string" primaryKey="true" /> </fields> <operationBindings> <operationBinding operationType="fetch" methodArguments="$criteria.aValue,$criteria.bValue,$criteria.cValue"> <serverObject className="com.sample.server.DMIHandler" methodName="getSome" /> </operationBinding> </operationBindings> </DataSource>

methodArguments goes on the operationBinding, not the serverObject.

Ah, great. Thanks.

But still not going.

Unable to assign a required or optional argument to slot #1 taking type: java.lang.Long of method:

public java.util.List com.sample.server.DMIHandler.getSome(java.lang.Long,java.lang.Long,java.lang.Long)

No remaining optional arguments match this type and all required arguments passed by the client have already been assigned.

Updated the operationBindings.

Code:

<DataSource ID="dmiMethod_DataSource" serverType="generic" schemaBean="com.sample.data.MyResultClass"> <fields> <field name="id" type="string" primaryKey="true" /> </fields> <operationBindings> <operationBinding operationType="fetch"> <serverObject className="com.sample.server.DMIHandler" methodName="getSome" methodArguments="$criteria.aValue,$criteria.bValue,$criteria.cValue" /> </operationBinding> </operationBindings> </DataSource>

Note you're also declaring redundant and conflicting methods - serverMethod and serverObject.methodName specify the same thing.

Didn't need a test case here, just needed to see your XML at all. It's malformed, causing your operationBindings to be ignored. See any sample; you need an <operationBindings> tag (note the "s") and then <operationBinding> tags within that (with attributes such as operationType).

As an aside, the test code makes a grid that is 'twitching' showing and hiding the scrollbars after it runs. This is using the TreeFrog skin.

Ok, I made a sample.

Here are the parts:

DataSource def

Code:

<DataSource ID="dmiMethod_DataSource" serverType="generic"
	schemaBean="com.sample.data.MyResultClass">
	<fields>
		<field name="id" type="string" primaryKey="true" />
	</fields>


	<operationBinding operationType="fetch">
		<serverObject className="com.teamsync.server.DMIHandler"
			methodName="getSome" methodArguments="$criteria.aValue,$criteria.bValue,$criteria.cValue" />
	</operationBinding>

</DataSource>

The data object to be returned

Code:

import java.io.Serializable;

public class MyResultClass implements Serializable {

	private static final long serialVersionUID = 7219106680608399931L;

	private String id;

	private String value;

	public void setId(String id) {
		this.id = id;
	}

	public String getId() {
		return id;
	}

	public void setValue(String value) {
		this.value = value;
	}

	public String getValue() {
		return value;
	}

}

The DMI method

Code:

public class DMIHandler {

	public List<MyResultClass> getSome(Long a, Long b, Long c) {
		List<MyResultClass> result = new ArrayList<MyResultClass>();
		MyResultClass test = new MyResultClass();
		test.setId("123");
		if (a != null && b != null && c != null)
			test.setValue("gimme some " + (a + b + c));
		else
			test.setValue("none for you");
		result.add(test);
		return result;
	}
}

And some code that uses it

Code:

		DataSource ds = DataSource.get("dmiMethod_DataSource");
		final ListGrid grid = new ListGrid();
		grid.setDataSource(ds);
	
		Button button1 = new Button("No criteria fetch");
		button1.addClickHandler(new ClickHandler() {
			@Override
			public void onClick(ClickEvent event) {
				grid.fetchData();
			}
		});

		Button button2 = new Button("Criteria fetch");
		button2.addClickHandler(new ClickHandler() {
			@Override
			public void onClick(ClickEvent event) {
				Criteria criteria = new Criteria();
				criteria.setAttribute("aValue", 1);
				criteria.setAttribute("bValue", 3);
				criteria.setAttribute("cValue", 5);
				grid.fetchData(criteria);
			}
		});

		VStack stack = new VStack();
		stack.addMember(button1);
		stack.addMember(button2);
		stack.addMember(grid);

		stack.setSize("100%", "100%");
		grid.setSize("400", "200");

		stack.draw();

And here is the stacktrace when it tries to fetch. First with no criteria, then with criteria.
