Hi,
I have initialized all 'lists' and 'selections' of all WOBrowsers
(1,2,3,4) at the time of page loading.
If i use WOBrowser1 and WOBrowser 2, i am able to select/move single or
multiple states from WOBrowser1 to WOBrowser2, and i can move back
single/multiple states to WOBrowser1.
But when i enabled another set of WOBrowsers with districts for selected
states i am not able to select/move Districts or States from one
WOBrowser to anothe WOBrowser.
Following is the code snippet:
--------------------------------------------------------------------------------------------------------
--WOD Code:
Browser1: WOBrowser {
displayString = availableState.name;
item = availableState;
list = availableStates;
selections = selectedAvailableStates;
size = 15;
multiple = true;
escapeHTML = false;
}
Browser2: WOBrowser {
displayString = selectedState.name;
item = selectedState;
list = selectedStates;
selections = selectedSelectedStates;
size = 15;
multiple = true;
escapeHTML = false;
}
Browser3: WOBrowser {
displayString = availableDistrict.name;
item = availableDistrict;
list = availableDistricts;
selections = selectedAvailableDistricts;
size = 15;
multiple = true;
escapeHTML = false;
}
Browser4: WOBrowser {
displayString = selectedDistrict.name;
item = selectedDistrict;
list = selectedDistricts;
selections = selectedSelectedDistricts;
size = 15;
multiple = true;
escapeHTML = false;
}
--Java Code--
// Initializing the variables
public State availableState;
public NSMutableArray availableStates = new NSMutableArray();
public NSMutableArray selectedAvailableStates = new NSMutableArray();
public State selectedState;
public NSMutableArray selectedStates = new NSMutableArray();
public NSMutableArray selectedSelectedStates = new NSMutableArray();
public District availableDistrict;
public NSMutableArray availableDistricts = new NSMutableArray();
public NSMutableArray selectedAvailableDistricts = new NSMutableArray();
public District selectedDistrict;
public NSMutableArray selectedDistricts = new NSMutableArray();
public NSMutableArray selectedSelectedDistricts = new NSMutableArray();
For single/multiple items move from one WOBrowser to another WOBrowser
selectedStates.addObjectsFromArray(selectedAvailableStates);
availableStates.removeObjectsInArray(selectedAvailableStates);

Hi.
What happens when you set all your arrays for the WOBrowser to an
empty array and not null?
I had a similar exception and set the 'list' and 'selections' arrays
to new NSArray(); when I initialized the component class. You would
have to do it for all your WOBrowsers.

Hi List,
I am using WOBrowser to select multiple objects.
For ex: WOBrowser 1 contains state objects, if any of the state
selected(moved to WOBrowser2 ) i am displaying Districts for that
state in the WOBrowser 3. To move state object from WOBrowser1 to
WOBrowser2 i am using WOImageButton.
First time i am able to select/move a single or multiple states from
WOBrowser1 to WOBrowser2, but after displaying districts in
WOBrowser3 , i tried to select/move a single district or if i tried
to select/move another state from WOBrowser1 to WOBrowser2, it
throws the following exception:
java.lang.UnsupportedOperationException: addAll is not a supported
operation in com.webobjects.foundation.NSArray
If i am not displaying district WOBrowsers on selecting the state
then i am able to select/move single or multiple states from
WOBrowser1 to WOBrowser2 and viceversa.

supported operation in com.webobjects.foundation.NSArray

Please suggest how to use more than 2 WOBrowsers in the same page.
