ColorPicker problems supporting transparency

[Lucianovici]

Hello,

I am using smartGWT3.0 pro / GWT 2.3.0
In the past when I used smartGWT 2.4 pro, things worked as expected, but now, when I use setSupportsTransparency(), I get an error (only when using development mode), in production the color picker is not displayed at all.

Attached is the error I get.

And here is the simple code that I have.

ColorPicker retColorPicker = new ColorPicker();
retColorPicker.setSupportsTransparency(true);
retColorPicker.setDefaultPickMode("complex");
retColorPicker.setDefaultColor(null != bgColor ? bgColor : "#FFFFFF");
...

If I comment the supports transparency property, then a similar error occurs for default pick mode, and finally if this is commented out, it works well but without the two properties I want!

Help please!
Thanks! You are building a great product, congratz.

And by the way: I get this log in GWT development mode, when the error occurs:

00:22:44.648 [INFO] Uncaught (javascript) exception com.google.gwt.event.shared.UmbrellaException: One or more exceptions caught, see full set in UmbrellaException#getCauses

In fact, I have many other places where this kind of error appears. Can you give me a hint please? What I am doing wrong.

Again, for instance I have a class field called adminTabSet and in a success callback of an async call to server I do this:

this.adminTabSet = getAdminTabSet();

Where getAdminTabSet() is defined like this:

private TabSet getAdminTabSet() {
        TabSet retTabSet = new TabSet();
        retTabSet.setTabBarPosition(Side.TOP);
        retTabSet.setTabBarAlign(Side.RIGHT);
        retTabSet.setTabBarThickness(ADMIN_TAB_BAR_THICKNESS);
        retTabSet.setShowTabPicker(isAdminTabScrollerRequired());
        retTabSet.setShowTabScroller(isAdminTabScrollerRequired());
        retTabSet.setWidth100();
        retTabSet.setHeight100();

...

The error I get:

"Error:Cannot change configuration property 'tabBarPosition' to top after the component has been created."

Why? The component was not created yet! It is created when getAdminTabSet() is called.

Help please.

I found this thread http://forums.smartclient.com/showthread.php?t=3786
But I am 100% sure I'm not calling .draw() before having all the components created.

It is clear that something wrong is happening with dev mode when debugging. I have now a standalone test case. Here it is a basic implementation of EntryPoint

public class TestIllegalStateException implements EntryPoint {
    @Override
    public void onModuleLoad() {
        VLayout testLayout = new VLayout();

        Label label = new Label();
//        label.setID("wtfLabel");
        label.setContents("Really?");
        testLayout.addMember(label);

        TabSet tabSet = new TabSet();
//        tabSet.setID("uniqueTabSet");
        tabSet.setTabBarPosition(Side.TOP);
        testLayout.addMember(tabSet);

        testLayout.draw();
}

When I am using GWT debug dev mode, the similar exceptions described are raised. But when I use run dev mode (without debugging, inspecting variables, etc) works perfectly also with the setID() lines uncommented.

Something is wrong with your project or IDE. Double-check the installation instructions, run a GWT compile, clear browser caches, and restart Eclipse. Maybe reboot too for good measure.

Yeah, it looks like there was something wrong there, but I remember that I encountered this kind of behavior back in the past.

However, I still have problems with my "complex" color picker.

Here is my standalone test case, implementing an EntryPoint:

        final ColorPicker colorPicker = new ColorPicker();
        /* Using the below static method to catch unhandled exceptions from GWT */
        GWT.setUncaughtExceptionHandler(new GWT.UncaughtExceptionHandler() {
            @Override
            public void onUncaughtException(Throwable e) {
                GWT.log("GWT uncaught exception: " + e.getMessage());
            }
        });
        colorPicker.setSupportsTransparency(true);
        colorPicker.setDefaultPickMode("complex");  /* CRASHING POINT! */
        colorPicker.setDefaultColor("#FFFFFF");
        colorPicker.addColorSelectedHandler(new ColorSelectedHandler() {
            @Override
            public void onColorSelected(ColorSelectedEvent colorSelectedEvent) {
                SC.say("Selected color is: " + colorSelectedEvent.getColor() + " and opacity: " + colorSelectedEvent.getOpacity());
            }
        });

        IButton btn = new IButton("Show colorPicker");
        btn.addClickHandler(new ClickHandler() {
            @Override
            public void onClick(ClickEvent clickEvent) {
                colorPicker.show();
            }
        });
        btn.draw();

When I use ColorPicker.setDefaultPickMode("complex"), I get the following log in dev mode console.
[INFO] GWT uncaught exception: One or more exceptions caught, see full set in UmbrellaException#getCauses

Surprisingly, when I use "simple" or comment that line, everything is working as expected.

Maybe this can be helpful to solve the bug: See attachment, to see how the color picker looks the second time I clicked the button. Looks "broken" :), wrongly sized, but functional, without the possibility to submit color/opacity.

Regards.

This last issue (the GWT uncaught exception one) was a framework bug which we have now fixed. The fix will be present in nightly builds of 2.5, 3.0 and 3.1d as of tomorrow.
