    Default [GXT 3.0.4] EmptyValidator<Date> causes JavaScriptException with IE7or8

    [GXT 3.0.4] EmptyValidator<Date> causes JavaScriptException with IE7or8


    Hi forum!

    I'm here for this issue that happens when i add an EmptyValidator<Date> to a DateField.
    Everything goes fine, but when you run it with IE7 or 8 during the "attaching" process of a panel that contains such DateField with null value, i get the "JavaScriptException: Invalid argument" and this translates in a totally messed up layout (information about top, left, height, width disappear from the outputted html).

    It really doesn't need any code example since i managed to reproduce such problem in many ways, but if you need some extra context just ask.

    Kind regards,

    Marcello

    I cannot try myself but i suspect this can be an issue on IE6 also. Thanks.

    In the last "caused by"i noticed the exception passing thorugh
    Code:
    TriggerFieldDefaultAppearance.onResize
    and that turned on a light: the problem lies in the method
    Code:
    .markInvalid(String message)
    of the DateField. I've implemented my brand new isCurrentValid() and i just needed to avoid this call to make everything smooth with IE7 and 8, obviously loosing my validation.
    For more precise context, i run this validation during the attachment of the parent panel: i make this in the constructor of such panel and, on a BorderLayoutContainer i make
    Code:
    .setCentralWidget(new WidgetWithDateField().asWidget(), layoutData)
    I'll try to make this before and let you know.

    Regards,
    Marcello.

    Aight, that's the problem.
    I've scheduled the validation with an AttachHandler, and limited it only if the widget is attached: all works fine.
    I can live with that but still doesnt seems right.

    Good day!

    Further investigation seems to suggest that this occurs in all browsers. I'm working on a fix now, hope to have it committed soon.

    My last reply may have been a little rash - there *is* a problem that will break in any browser, but it doesn't appear to directly correspond to the stack trace you are seeing, which seems uniquely IE-related. That said, I can't yet reproduce it.

    Can you share an example that causes this issue and the version of GXT you are using?

    This test fails in all browsers:
    Code:
      public void testDetachedEmptyValidator() {
        DateField field = new DateField();
        field.setAllowBlank(false);
    
        try {
          // in some browsers (including HtmlUnit) this will fail
          field.validate();
        } catch (Throwable t) {
          fail("Error occured when validating + " + t.getMessage());
          t.printStackTrace();
        }
      }
    This is what I expected would fail in IE8, but didn't:
    Code:
      public void testDetachedEmptyValidator() {
        DateField field = new DateField();
        field.setAllowBlank(false);
    
        FlowPanel parent = new FlowPanel();
        parent.add(field);
    
        try {
          // in some *other* browsers (IE), this may fail - even though it has a parent, it has no size as it isn't visible
          field.validate();
        } catch (Throwable t) {
          fail("Error occured when validating + " + t.getMessage());
          t.printStackTrace();
        }
      }
    Can you shed a little light on the IE-specific nature of your use case? I'd like to fix both issues is possible, but I need to understand the IE case to do that.

    I'm marking this as fixed for now, as the issues discussed in my last post have been fixed, and I haven't managed to get any more details yet on an IE-specific issue. This fix is in SVN and the nightly builds, and will be available in the next release.

    If you have more details about the IE-specific issue (especially if you can reproduce with the latest nightlies), I'd appreciate any further information so I can reopen this and fully resolve it.

    The real code is pretty huge to be posted...if I manage to get some spare time I'll try to make a small example.
    The last examples you made are the core of the issue: cast a validation on a date field still not attached to the browser. Fast example:

    Code:
    public class TestClass implements IsWidget {
    private Widget component;
    public TestClass () {
    //create date field, attach it to the panel
    component = uiBinder.createAndBindUi(this);
    //load & validate();
    }
    @Override
    public Widget asWidget() {
    return this.component;
    }
    }
    if this runs like

    Code:
    RootPanel.get().add(new TestClass().asWidget());
    it will fail, during the construction. If I create without validation, attach, and then validate all goes fine.
    Those code lines in the TestClass solved my problems.

    Code:
    public void customValidation() {
    if (asWidget().isAttached()) {
    //validate
    }
    } //to put in the constructor asWidget().addAttachHandler(new Handler() {
    @Override
    public void onAttachOrDetach(AttachEvent event) {
    if (event.isAttached()) {
    customValidation();
    }
    }
    });
    I suspect that the problem is the IE7's (and 8's) javascript interpretation of the markInvalid method when it actually wants to put the red ! mark next to a field invalid and not yet attached.

    If you need further info, please ask.
    Regards

    One thought then - can you confirm that this same bug happens in other browsers? If so, I think we've got it licked.

    If not, could you try one of the latest nightly builds from support.sencha.com to verify that it is all working correctly after our fixes?
