PDPushButton Appearance

[clovis]

Hi,

I'm using 2.0.0-RC3 and trying to add a push button to submit the form to a
web app.
Following the samples, I wrote the following code.
I can add boder and backgorund color to the Text Field. But the Push Button
is still invisible. I can click on it but I can't see it.
What is wrong?


        // Add a new AcroForm and add that to the document
        PDAcroForm acroForm = new PDAcroForm(doc);
        doc.getDocumentCatalog().setAcroForm(acroForm);

        // Add and set the resources and default appearance at the form
level
        acroForm.setDefaultResources(resources);
        String defaultAppearanceString = "/Helv 0 Tf 0 g";
        acroForm.setDefaultAppearance(defaultAppearanceString);

        // Add a form field to the form.
        PDTextField textBox = new PDTextField(acroForm);
        textBox.setPartialName("SampleField");
        // Acrobat sets the font size to 12 as default
        // This is done by setting the font size to '12' on the
        // field level.
        defaultAppearanceString = "/Helv 12 Tf 0 g";
        textBox.setDefaultAppearance(defaultAppearanceString);

        // add the field to the acroform
        acroForm.getFields().add(textBox);

        // Specify the annotation associated with the field
        PDAnnotationWidget widget = textBox.getWidgets().get(0);
        PDRectangle rect = new PDRectangle(50, 750, 100, 20);
        widget.setRectangle(rect);
        PDAppearanceCharacteristicsDictionary fieldAppearance = new
PDAppearanceCharacteristicsDictionary(new COSDictionary());
        PDColor blue = new PDColor(new float[] { 0, 0, 1 },
PDDeviceRGB.INSTANCE);
        fieldAppearance.setBorderColour(blue);
        widget.setAppearanceCharacteristics(fieldAppearance);

        // Add the annotation to the page
        page.getAnnotations().add(widget);

        // set the field value
        textBox.setValue("Sample field");
        // Add a form field to the form.
        PDPushButton pb = new PDPushButton(acroForm);
        pb.setPartialName("push");

        // add the field to the acroform
        acroForm.getFields().add(pb);

        // Specify the annotation associated with the field
        widget = pb.getWidgets().get(0);
        rect = new PDRectangle(250, 730, 100, 20);
        widget.setRectangle(rect);
        fieldAppearance = new PDAppearanceCharacteristicsDictionary(new
COSDictionary());
        blue = new PDColor(new float[] { 0, 0, 1 }, PDDeviceRGB.INSTANCE);
        fieldAppearance.setBorderColour(blue);
        fieldAppearance.setBackground(blue);
        fieldAppearance.setNormalCaption("teste");
        widget.setAppearanceCharacteristics(fieldAppearance);
        // Add the annotation to the page
        page.getAnnotations().add(widget);

        contents.close();
        doc.save(filename);
