Date browsers problem - if manually changed and focus on it - did not save

问题

I have a problem related to Date type which I'm using in smartgwt.

I set up the date to have the possibility to change it manually:

setAttribute("useTextField", true);

In Firefox and Chrome (and maybe other browsers , except Internet Explorer) if first I'm selecting a date with that pop-up calendar and than change it manually and then let the focus on the date field and going to save the document (actually is a form with multiple fields) the date changed manually it is lost, the date choosed from calendar it is saved. This is not happening in Internet Explorer.

In all browsers, if I select from Calendar a date and than change it manually and change the focus from it everythings goes fine - the manually changed date it is saved into db. Need some advices.

Thank you a lot.

I'm using com.smartgwt.client.widgets.form.fields.DateItem widget.

DateItem date = new DateItem("A date");
date.setWidth(320);
date.setWrapTitle(false);
date.setAttribute("useTextField", true); 
date.setAttribute("inputFormat", "yyyy/MM/dd");
date.setAttribute("displayFormat", "toJapanShortDate");

I'm adding this date on a DynamicForm:

DynamicForm  form = new DynamicForm();
form.setFields(date);

and this form on a VLayout object:

VLayout editLayout = new VLayout(30);
editLayout.addMember(form);

The problem is reproducing in browsers like Firefox & Chrome when:

I'm selecting first the date from calendar - say I'm selecting 2011/02/11
I'm changing the day in 2011/02/12 manually - and I'm not changing the focus from this date field
I'm pressing the 'Save' button.

After these steps the date is 2011/02/11 and not 2011/02/12 how it should be. In Internet Explorer browser did not happen - the date after the steps above is 2011/02/12!

I'm using a DataSource for updating the data.

I'm having a UserObject and in the userUpdate method I'm creating this user object first with values from fields (which are on the DynamicForm) - by calling the generateUserObjectFromForm() method

UserObject   user = generateUserObjectFromForm();

Here, in this method I'm doing something like: user.setAddedDate(date.getValueAsDate()), but here the date.getValueAsDate() value is the one selected from calendar, not the one modified manually.

I've tried also with:

date.getValue() //Fri Feb 11 00:00:00 GMT+200 2011  
date.getValueField() // null
date.getValueAsDate() //Fri Feb 11 00:00:00 GMT+200 2011
date.getDisplayField() //null
date.getDisplayValue()//l2011/02/11

but none worked properly.

I'm using an request object (UserUpdateRequest) for updating the user.

UserUpdateRequest looks like:

public class UserUpdateRequest implements IsSerializable
{
    UserObject user = null;

    public UserUpdateRequest ()
    {
    }

    public UserUpdateRequest (UserObject user)
    {
        this.user = user;
    }

    public UserObject getUser ()
    {
        return user;
    }
}

final UserUpdateRequest request = new UserUpdateRequest(user);

and on the RPC user update method I'm sending this UserUpdateRequest request.

Later edit (15 february):

I've discovered why is happening this issue related to focus, and this is because in the project I'm not using a Button object - and a com.google.gwt.event.dom.client.ClickEvent for it. I'm using a personalized widget:

package de.vogella.gwt.helloworld.client;
import com.smartgwt.client.widgets.Label;

public class buttonLabel extends Label
{
    public buttonLabel (String text, String elementID)
    {
        super();
        setContents(text);
        setAutoWidth();
        setBaseStyle("wwHoverLabel");
        setShowRollOver(true);          
    }

}

and this use com.smartgwt.client.widgets.events.ClickHandler().

Anyway I do not know how to resolve this ....

I've created a small project with this issue where I've put also a Button object (Save1) and also a personalized button buttonLabel (Save2) - both with clickhandlers.

Here is the link where you can download sources of this small project I've created: link

Case1: say for example we choose date 2011/02/16 and we change manually the date into 2011/02/17 and push the button Save1 - everything works fine - the date remains 2011/02/17

Case2-a - line Window.alert("2 " + date.getValue()); un-commented: say for example we choose date 2011/02/16 and we change manually the date into 2011/02/17 and push the button Save2 - in the warning message date value is 2011/02/16 but in the field date remains 2011/02/17

Case2-b - line Window.alert("2 " + date.getValue()); uncommented: say for example we choose date 2011/02/16 and we change manually the date into 2011/02/17 and push the button Save2 - the value from field date is automatically changed to 2011/02/16

Later later edit:

Since I can't figure out how to solve my problem I'm thinking for the moment at a temporary solution. So, I have:

DateItem date = new DateItem("Adate");
date.setWidth(120);
date.setWrapTitle(false);
date.setAttribute("useTextField", true); 
date.setAttribute("inputFormat", "yyyy/MM/dd");
date.setAttribute("displayFormat", "toJapanShortDate");

Because the attribute useTextField is set to true we can see the text entry field. How can I make this text entry field to be un-editable. Actually I want to have only the possibility to choose the date from calendar and not to change it manually.

回答1:

The following code should work.

DateItem date = new DateItem("Adate"); 
date.setAttribute("useTextField", true); 
date.setAttribute("inputFormat", "yyyy/MM/dd"); 
date.setAttribute("displayFormat", "toJapanShortDate"); 
TextItem textItem = new TextItem(); 
textItem.setAttribute("readOnly", "true"); 
date.setTextFieldProperties(textItem);
