Problem with Auto Complete TextField

[mikko.nu...@gmail.com]

Hi,

I'm having trouble with AutoCompleteTextField, it seems to cause NullPointer in real device (Samsung / Android, iPhone 5 / iOS) when initial text is set to it (.setText("foo")) and while it is added to a container. Again this works fine with simulator. In my case I'm trying to fill the component with contact emails from phone memory. The text that I want to initially set is also some persons email but that is not necessarily from the that phones memory. Ok, that "might" have been understandable that setting the text that is not in the list (String[]) of AutoCompleteTextField causes someting like this, but I also tried to add the initial value to that list and that didn't work. The software does not render any other components when method below is called (another methods alike [creating different components] are not called any more). This works fine if I comment the setText(text) away from the code but it is problem because user does not know which value it is editing.

 public static void createAutoCompleteWithHeader(String header, Container container, String text, String variable,
        String[] items, int constraint) {

        HeaderLabel headerLabel = new HeaderLabel();
        headerLabel.setText(header);
        headerLabel.setName("header");

        AutoCompleteTextField autoCompleteTextField = new AutoCompleteTextField(items);
        autoCompleteTextField.setText(text);
        autoCompleteTextField.setLabelForComponent(headerLabel);
        autoCompleteTextField.setConstraint(constraint);

        container.addComponent(headerLabel);
        container.addComponent(autoCompleteTextField);
    }

Thanks.
This is probably related to a fix made to a different issue, we'll fix the exception.

Hello,

no problem, glad that is a clear case. How do we know when the component is usable again?

Hey guys,

I am getting a similar error: NullpointerException when I click on the AutocompleteTeextfield component this is the error:

java.lang.NullPointerException

On this exact line in bold of the following block in theAutoCompleteTextField.class:

popup.addComponent(l);

        popup.getStyle().setMargin(LEFT, getAbsoluteX());

        byte [] units = popup.getStyle().getMarginUnit();

        units[Component.LEFT] = Style.UNIT_TYPE_PIXELS;

        popup.getStyle().setMarginUnit(units);

oopss sorry forgot to mention, this is only happening on the simulator, not on normal devices, or at least the ones I've used.

There was a regression in the latest release that we since fixed on the build servers.
It will be fixed in the next library update.
