DefaultComboBoxModel setSelectedItem throws IndexOutOfBoundException #50

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
What I want to do is to deselect selected item in combo. First , I usIte 
ComboBox setSelectedIndex with index -1, like Swing. But it did not work, 
because, setSelectedIndex method reject -1 as index. 
Then , I checked , DefaultComboBoxModel setSelectedItem method. it says 
that it will accept null values. But, it throws below exception,

[ERROR] Uncaught exception escaped
java.lang.ArrayIndexOutOfBoundsException: -1
    at java.util.Vector.get(Vector.java:696)
    at org.gwt.mosaic.ui.client.list.DefaultComboBoxModel.getElementAt

(DefaultComboBoxModel.java:44)
    at 
org.gwt.mosaic.ui.client.list.DefaultComboBoxModel.setSelectedItem
(DefaultComboBoxModel.java:105)

What is the expected output? What do you see instead?
deselect selected combo item.. 

What version of the product are you using? On what operating system?
gwt-mosaic-0.2.0-rc3
windows vista

Please provide any additional information below.

Hi,

DefaultComboBoxModel.setSelectedItem() should work now:

Hi,

First of all,  I wanna thank for your effort. 
DefaultComboBoxModel.setSelectedItem() 
is working now. But these modifications unfortunately broke my incremental 
search 
combo. After these changes, Whenever ComboBox setSelectedIndex or model 
setSelectedItem method is called, popup is closed and the combo editor is 
filled 
with the selected item. The behaviour should be like that, whenever popupwindow 
is 
visible, setSelectedIndex or setSelectedItem should not cause above behaviour. 
User 
should press the enter to change the selected item of the combo, when the popup 
window is visible.

I hope i could express what my requirements are..

Thanks again..

Hi,

Thanks again george. But the latest changes also are not useful for me. I have 
attached a combo demo. you can see the combobox behaviour by means of this 
demo. 

Thanks again..

Hi,

Unfortunately, combobox behaviour again is not consistent. You can easily check 
with 
combobox demo that I have posted yesterday. It is a prototype for incremental 
search 
combo. 

Thanks for your efforts..

Hi Gursel,

what I see there is that while typing only the last character is visible on the 
text
box. I was working on incremental search last Saturday but I started with a 
ListBox
not with ComboBox directly. I will commit next week after I finish the
FilteredListModel. If you like please send me any patches you have for ComboBox 
that
work for you.

Thanks,
George.

Hi,

DefaultComboBox & ListBox have been redesigned in 0.2.1, see:

http://groups.google.com/group/gwt-mosaic/browse_thread/thread/38231a1362039922

do you have still the same problem? I also added a new list model 
(FilterProxyListModel).

Kind Regards,
George.

Hi George, 

I have supposed that I have solved the problem.. You should comment 
updateInput() 
line of selectedItemChanged() method of ListDataListener inner class inside 
ComboBox 
constructor.. 

Regards

Gursel

Hi, by commenting out updateInput() the default functionality does not work.

Kind Regards,
George.
