Re: ERXPatcher / WOBrowser / NSArray.addAll()
Hmm…
The problem is that I'm getting the exception in the takeValues phase, so
changing it from updating the binding from invokeAction to appendToResponce has
no impact as they both happen after the error is already being thrown.
This is really seeming like a bug in WOInputList#listClassInContext(WOContext)
in that it returns an NSArray by default if the binding is null or otherwise
not an instanceof NSArray or List.
I believe it should return an NSMutableArray instead.

Re: ERXPatcher / WOBrowser / NSArray.addAll()
Hi Michael,
Yes, you are exactly right, except that we are setting the contents of the list
binding (by assigning a new value to the ivar it's bound to) in invokeAction.
public MyComponent showChoicesForSelection(){
if (selectedCategory() != null){
assignedChoices = selectedCategory().relatedChoices();
}
return thisPage();
}
selectedCategory() returns the value of the selections binding from a different
WOBrowser component, and relatedChoices() is simply a toMany relationship.
While initializing the ivar to NSArray.emptyArray() avoids the exception being
thrown, I'm seeing that it is still broken code in the sense that we are
changing the contents of the list binding at an unexpected time.

Re: ERXPatcher / WOBrowser / NSArray.addAll()
Yes, that "works around" the problem, but I'm still trying to understand why
WOBrowser (and possibly other WOInputList-based components) can't handle the
contents of the list binding changing during takeValuesFromRequest.
I find it interesting that instead of fixing this problem or at least keeping
an exception from happening, The Apple developers chose to simply swallow the
exception and pretend nothing happened.

Re: ERXPatcher / WOBrowser / NSArray.addAll()
I blame myself personally. I overrode that method to prevent swallowed
exceptions but overlooked an obvious use case. It should probably be
if(result instanceof NSMutableArray) {
((NSMutableArray)result).addObjects(selections.toArray());
} else if(result instanceof NSArray) {
result = new NSArray(selections);
} else if(result instanceof List) {
((List)result).addAll(selections);
}
Same for radiobuttonlist and checkboxlist

Re: ERXPatcher / WOBrowser / NSArray.addAll()
Hi David:
Even thought the exception says something about "addAll is not a
supported operation in com.webobjects.foundation.NSArray" that is not
what causes this issue. We experienced a similar issue. The problem for
us was that we were using dependent WOBrowser components (that's what it
sounds like you are doing) and bind the list binding of the dependent
WOBrowser to a method that has a conditional base upon what was selected
in the first WOBrowser, e.g.
categoryWOBrowser : WOBrowser {
...
selection = selectedCategory;
...
}
dependentWOBrowser : WOBrowser {
list = dependentList;
...
}
public NSArray dependentList() {
if (selectedCategory == "ABC") return category1Array;
else if (selectedCategory == "DEF") return category2Array
...
}
If you change the selectedCategory and submit the form (via Ajax or form
submit) then in takeValuesFromRequest the dependentWOBrowser list
binding gets evaluated and the method returns a different list. But the
list should really not change until appendToResponse.
In our case, we set dependentList in appendToResponse, so dependentList
becomes a setter/getter.
Michael.

We're suddenly running into the WOBrowser
"java.lang.UnsupportedOperationException: addAll is not a supported
operation in com.webobjects.foundation.NSArray" problem as others have
run into.
We have a WOComponent that has three WOBrowsers on it. One selects one
or more "Categories" from all possibilities. The other two manage what
related objects are related to the selected Categories. One with
Available Objects, and one with Assigned Objects. Basically, with 3
WOBrowsers we are managing a Many-to-Many relationship.
Now, we can easily avoid the error by just making sure that the
"selections" bindings of the WOBrowsers are not null. Initializing
them with NSArray.emptyArray() works just fine.
There are two odd things:
1) We just started running into this problem and this code has been
running unchanged for years, and Wonder's last change was 16+ months ago
2) There are three WOBrowsers on the Page (2 in one component, 1 in a
parent component) and only ONE of the WOBrowsers is causing this error.
I believe there is a bug in WO's or WOnder's handling of WOBrowser,
but maybe (probably) I'm just not fully understanding the implications
of multiple WOBrowsers in one Page and the Request-Response loop.
526if(_selections!=null&&_selections.isValueSettable()) {
526 try {
527 ClassresultClass=listClassInContext(context);
528 Object result = resultClass.newInstance();
529 if(resultinstanceofNSMutableArray) {

531 } else {

533 ((List)result).addAll(selections);
534 }
535 }
536 _selections.setValue(result,context.component());
537 } catch(Exception exception) {
If I add the following two lines:
531 + } else if (result instanceof NSArray) {
532 + result = new NSArray(selections.toArray());
Or surround lines 529 - 535 with the following if clause:
529 + if(selections !=null&&!selections.isEmpty()) {
...
537 +}
Then everything works just fine, even if the selections bindings end
up null.
That's all very special, but it just covers up the real problem by
intercepting the bad data before it can cause an error. They don't fix
what is causing the bad data in the first place.
It appears that for some reason line 527's call to
EOAssociation#listClassInContext(context)for just ONE of the three
WOBrowsers returns an instance of NSArray instead of an
NSMutableArray. The one that gets an NSArray Class is the third
WOBrowser on the page, but possibly more significantly it'sthe second
with a null "selections" binding.
What I don't get is why would
EOAssociation#listClassInContext(context)return different Class
objects (NSMutableArray for the first, NSArray for the second) even
when both WOBrowser "selections" bindings are null?
Does anybody have any ideas?

indirectly involve bourbon and/or hookers)

Fix: Make sure listClassInContext(context) method is returning mutable object
most likely NSMutableArray.

ERXPatcher / WOBrowser / NSArray.addAll()
Hey all,
I'm in over my head again. But at least the "good" news is that I think I'm
finally inching my way toward the deep end of the pool...
We're suddenly running into the WOBrowser
"java.lang.UnsupportedOperationException: addAll is not a supported operation
in com.webobjects.foundation.NSArray" problem as others have run into.
We have a WOComponent that has three WOBrowsers on it. One selects one or more
"Categories" from all possibilities. The other two manage what related objects
are related to the selected Categories. One with Available Objects, and one
with Assigned Objects. Basically, with 3 WOBrowsers we are managing a
Many-to-Many relationship.
Now, we can easily avoid the error by just making sure that the "selections"
bindings of the WOBrowsers are not null. Initializing them with
NSArray.emptyArray() works just fine.
There are two odd things:
1) We just started running into this problem and this code has been running
unchanged for years, and Wonder's last change was 16+ months ago
2) There are three WOBrowsers on the Page (2 in one component, 1 in a parent
component) and only ONE of the WOBrowsers is causing this error.
I believe there is a bug in WO's or WOnder's handling of WOBrowser, but maybe
(probably) I'm just not fully understanding the implications of multiple
WOBrowsers in one Page and the Request-Response loop.
526if(_selections != null && _selections.isValueSettable()) {
526try {
527Class resultClass = listClassInContext(context);
528Object result = resultClass.newInstance();
529if(result instanceof NSMutableArray) {
530((NSMutableArray)result).addObjects(selections.toArray());
531} else {
532if(result instanceof List) {
533((List)result).addAll(selections);
534}
535}
536_selections.setValue(result, context.component());
537} catch(Exception exception) {
If I add the following two lines:
531 + } else if (result instanceof NSArray) {
532 + result = new NSArray(selections.toArray());
Or surround lines 529 - 535 with the following if clause:
529 + if (selections != null && !selections.isEmpty()) {
...
537 +}
Then everything works just fine, even if the selections bindings end up null.
That's all very special, but it just covers up the real problem by intercepting
the bad data before it can cause an error. They don't fix what is causing the
bad data in the first place.
It appears that for some reason line 527's call to
EOAssociation#listClassInContext(context) for just ONE of the three WOBrowsers
returns an instance of NSArray instead of an NSMutableArray. The one that gets
an NSArray Class is the third WOBrowser on the page, but possibly more
significantly it's the second with a null "selections" binding.
What I don't get is why would EOAssociation#listClassInContext(context) return
different Class objects (NSMutableArray for the first, NSArray for the second)
even when both WOBrowser "selections" bindings are null?
Does anybody have any ideas?

Re: WOBrowser Error java.lang.UnsupportedOperationException: addAll is not a supported operation in com.webobjects.foundation.NSArray
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);
--Pavan.

Hi.
What happens when you set all your arrays for the WOBrowser to an

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.

Re: WOBrowser Error java.lang.UnsupportedOperationException: addAll is not a supported operation in com.webobjects.foundation.NSArray
Hi: We had this same error. And by the sounds of it, you have a similar setup. WOBrowser 1 is a what I call dependent list. Select a row in the list, some Ajax gets executed and some other elements on the page change. Our WOBrowser 1 was a Fiscal Year selector. This is a timing issue. You would need to cache the list (NSArray) for WOBrowser 1 once per RR-loop. We overrode appendToResponse and initialized the cached value of the list there. The problem for us was that we bound the list binding directly to an EO. That means that during the RR-loop the list binding changed, from one array to another. I hope that helps. Michael.

I have had this problem. I griped about it in a thread within the last year or
so. I had the propagate primary key set weirdly and the WOLips tools did not
respond to my off-kilter suggestions.
I find that once I make sure the intermediate relationships are not class
properties and set the propagate primary key to both joins and set the deletion
policy correctly, things always end up working. I think Mike told me to just do
the setup in the normal way and get over myself with my weird setup.
The validation warnings from the tools are not very smart about many-to-many
relationships, or so it seems to me.

Re: Flattened many-to-many with WOBrowser
Hi James,
When you flatten a Many to Many, I believe that EOF expects that it is a
compound PK, and that is what it is trying to find. I appears that you have an
independent PK for that join table. Either remove the flattening, or use a
compound PK.
I really dislike compound PKs, but sometimes, you just have to let EOF do it's
thing.

Flattened many-to-many with WOBrowser
Here is the error:
A valid global ID could not be obtained for entity named
PortfolioProjectPortfolioProject, relationship named childProjects, primary key
dictionary {childProjectRowId = 69063; }
The project with that row id (69063) does exist and would be the correct one.
WOBrowser:
childProjects: WOBrowser {
displayString = aChildProject.title;
item = aChildProject;
list = possibleChildProjects;
selections = theNewProjectItem.childProjects;
multiple = true;
}
theNewProjectItem.childProjects is the "flattened relationship".
What am I missing here?

RE: WOBrowser selections missing
Found the answer to this. Apparently we don't want to have both displayString
and value properties on our WOBrowser.
Removed value - works fine now - corrected version:
Browser3: WOBrowser {
displayString = currentClient.displayName;
item = currentClient;
list = clientList;
multiple = true;
selections = selectedClientList;
style = "width:270px";
}

Having some WOBrowser weirdness, after upgrading from OS X 10.5 to 10.6 (Snow
Leopard) and from WebObjects 5.3.x to 5.4.1. This issue did not happen prior
to the upgrade. Problem is, the selected items from our WOBrowser are not
being passed correctly to our Java code.
So I tried running this in Eclipse debug. My WOBrowser has about 450 items in
it.
* If I selected the first item in the list, selectedClientList contains
the one item. Cool.
* But if I selected any other item besides the first,
selectedClientList is empty.
* And if I multi-select 3 or 4 items, sometimes selectedClientList is
empty, and other times it will have just the first item I selected.
Any thoughts on what could be causing this?
Here's our WOBrowser. "selectedClientList" is defined as public NSArray in the
accompanying java class.
Browser3: WOBrowser {
displayString = currentClient.displayName;
item = currentClient;
list = clientList;
multiple = true;
selections = selectedClientList;
style = "width:270px";
value = currentClient.displayName;
}

You rock Hugi! This is way more complete than I had come up with so far! Next on my list is to D2Wify it for ERModernLook integration.

Yeah, that's exactly what I'm working on implementing. I was just wondering if anyone else had already done it in a nice CSS/Ajaxy way so I could get a jump start.

Am 12.02.2008 um 14:14 schrieb Sennikov, Dimitri:
I only have 1-to-many, a user can be a part of several departments

Are you sure, your model has a relationship?
It sounds, like you try to have an NSArray as a column, not as a
relationship?
From Entity Modeler, the relationship is represented by departmentIDs
column with the following settings:
A COLUMN can not be a relationship.
Prototype - mutableArray
External Type - BLOB
Allows Null - is set
Data Type - Custom
What is that for?
Do you want to store the names of your departments in that?
Class - er.extensions.ERXMutableArray
Factory Method - fromBlob
Conversion Method - toBlob
Are you converting the blobs somewhere? What do they contain?
Here's my WOBrowser object:
DepartmentList : WOBrowser {
list = departmentDisplayGroup.displayedObjects;
item = department;
displayString = department.name;
selections = user.departments;
Is user.departments your blob? That will not work.
multiple = true;
size = 6;
}
A relationship is a join, not a column.
Your following sentence is not true:
I only have 1-to-many, a user can be a part of several departments
whereas department has no relationship with any user from its side.
If one user can have many departments and multiple users can have the
same departments, you have a n-m, and nothing else.
You need a m-n table in your database (USER_DEPT) and connect User and
Department with a 1-n to it.

It appears that EOF is attempt to set the ID column to null for the

Is there a many-to-many relationship between User and Department?

Re: WOBrowser
Hello Mike, This is just the way the select works in the browser. To deselect the last item, you have to command-click (on a Mac) or control-click (on WIndows). It shouldn't be hard to add a button that deselects all, using javascript, if you want to give the users another alternative.

The specific behavior I want is for the user to be able to deselect ALL of the elements in the list thus removing all related objects. Is it possible to accomplish this using WOBrowser? If the 'size' binding is greater than the number of elements in the list, I am able to click below the list but inside WOBrowser and get the desired behavior. I have tried various combinations of bindings to no avail. Is there a better general purpose solution, or hack? I am specifically using WOBrowser because my client did not accept the particular UI described by Malcolm Crawford in his excellent article on StepWise concerning a re- useable relationship inspector.
