I seem to be getting this error on the following:

if(sortListGridField.getSortDirection() == SortDirection.ASCENDING) {

Has anyone else seen this with ListGridField.getSortDirection()?

[Isomorphic]

Tested with the following code and could not reproduce. Please provide a more complete test case that reproduces the problem.

                final ListGridField field= new ListGridField();
//		field.setSortDirection(SortDirection.ASCENDING);
		
		Button button = new Button();
		button.addClickHandler(new ClickHandler() {
			@Override
			public void onClick(ClickEvent event) {
				SC.say("Compare " + (field.getSortDirection()==SortDirection.ASCENDING));

			}
		});
		button.draw();

[JLivermore]

Give this a try:

final ListGridField field= new ListGridField();
		field.setSortDirection(SortDirection.ASCENDING);

        TreeGrid treeGrid = new TreeGrid();
        treeGrid.setFields(field);
        final ListGridField testField = treeGrid.getField(treeGrid.getSortField());

        Button button = new Button();
        button.addClickHandler(new ClickHandler() {
            @Override
            public void onClick(ClickEvent event) {
                SC.say("Compare " + (testField.getSortDirection() == SortDirection.ASCENDING));

            }
        });

[Isomorphic]

I wasn't able to run your code as you have it. I modified it so it would run and not throw NPE's on execution, but still cannot reproduce the issue.

		final ListGridField field= new ListGridField();
		field.setSortDirection(SortDirection.ASCENDING);

        final TreeGrid treeGrid = new TreeGrid();
        treeGrid.setFields(field);
        treeGrid.setTop(30);
        treeGrid.draw();
        
        Button button = new Button();
        button.addClickHandler(new ClickHandler() {
            @Override
            public void onClick(ClickEvent event) {
//                final ListGridField testField = treeGrid.getField(treeGrid.getSortField());
                SC.say("Compare " + (field.getSortDirection() == SortDirection.ASCENDING) );

            }
        });
        button.draw();

[JLivermore]

can you try this test case:

private void testcase2() {
        Window win = new Window();
        final ListGridField field= new ListGridField("name1", "Name 1");
        field.setSortDirection(SortDirection.ASCENDING);

        final TreeGrid treeGrid = new TreeGrid();
        treeGrid.setFields(field);
        treeGrid.setTop(30);
        win.addMember(treeGrid);
        treeGrid.draw();

        Button button = new Button();
        button.addClickHandler(new ClickHandler() {
            @Override
            public void onClick(ClickEvent event) {
                final String sortField = treeGrid.getSortField();
                GWT.log("sortField:" + sortField);
                final ListGridField testField = treeGrid.getField(sortField);
                SC.say("Compare " + (testField.getSortDirection() == SortDirection.ASCENDING) );

            }
        });
        win.addMember(button);
        button.draw();
        win.show();

    }

which produces this error:

I think the problem may be in ListGrid.getSortField()?

[Isomorphic]

We were able to reproduce the issue with your last example. Once we have a fix for the problem we will let you know.

[Isomorphic]

A fix has been found for this, you should see it in tonights nightly build of 4.1.

I was unable to verify the nightly build from 2-26 with this issue. The following test case produces this stack trace now from the client side. Please see below:

    private void testcase2() {
        Window win = new Window();
        final ListGridField field= new ListGridField("name1", "Name 1");
        field.setSortDirection(SortDirection.ASCENDING);

        final TreeGrid treeGrid = new TreeGrid();
        treeGrid.setFields(field);
        treeGrid.setTop(30);
        win.addMember(treeGrid);
        treeGrid.draw();

        Button button = new Button();
        button.addClickHandler(new ClickHandler() {
            @Override
            public void onClick(ClickEvent event) {
                final String sortField = treeGrid.getSortField();
                GWT.log("sortField:" + sortField);
                final ListGridField testField = treeGrid.getField(sortField);
                SC.say("Compare " + (testField.getSortDirection() == SortDirection.ASCENDING) );

            }
        });
        win.addMember(button);
        button.draw();
        win.show();

    }

ListGrid.getSortField() appears to still be giving me a NULL in this test case. Can you confirm this on your end?

Here is a variation on the same theme with different results:

ListGrid.getSortField() does not return NULL, however, in the Button.onClick the very last line when we call

SC.say("testfield.getSortDirection : " + testField.getSortDirection());

a new exception listed below is thrown.

private void testcase3() {
        Window win = new Window();
        final ListGridField field= new ListGridField("name1", "Name 1");

        final TreeGrid treeGrid = new TreeGrid();
        treeGrid.setFields(field);
        treeGrid.setTop(30);

        SortSpecifier[] sort = {new SortSpecifier("name1", SortDirection.ASCENDING)};
        treeGrid.setSort(sort);

        win.addMember(treeGrid);
        treeGrid.draw();

        Button button = new Button();
        button.addClickHandler(new ClickHandler() {
            @Override
            public void onClick(ClickEvent event) {
                final String sortField = treeGrid.getSortField();
                GWT.log("sortField:" + sortField);
                final ListGridField testField = treeGrid.getField(sortField);
                SC.say("testfield.getSortDirection :  " + testField.getSortDirection());


            }
        });
        win.addMember(button);
        button.draw();
        win.show();

    }

testcase3 (posted earlier) has been fixed.

testcase2 is still not working.

Hi checking in to see if there is any update to this issue?

[Isomorphic]

After re-analyzing testcase 2, it seems like the crash you're seeing would be expected. You configured a default sorting direction for the sole field of the TreeGrid, but you have not actually told the TreeGrid to sort.

Therefore sortField = treeGrid.getSortField() is null, and testField = treeGrid.getField(sortField) is also null and you are trying to call ListGridField.getSortDirection() on null.
