[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.

Toying to find a good workaround i found more clues.

Here's my stackTrace

Code:

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.

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!
Marcello

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.

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?
