"must choose at least one" validation in dataTable?

Hello, group,
How do you validate a set of checkboxes, one per table row, in which the user must select at least one?
We have a page containing a dataTable, each row of which represents an object, one of whose attributes is "active". Our requirement is that at least one object must be selected as "active" by the user.
How do we validate this?
I'm considering the following:
(1) Put a validator on each checkbox that simply increments a count in a request-scoped bean if the checkbox is checked (and always returns success).
(2) Put a validator on a hidden field at the bottom of the form that requires the count be greater than zero.
Is there a better way? (Will this even work at all? :) )
Thanks.
John.

Looks interesting, thank you very much.
I would actually need the multiple row selector, I think, since the requirement is at least one. I see there's no "validator" attribute, but I assume we could just hang a f:validator off of it (or write our attribute and submit a patch!).
That jenia component set looks good for some other requirements we have.
John.

Background job getting cancelled : Choose at least one scope of list

Hello to all,
I am trying to Run on Z report in background which conatins SUBMIT statement to standard progarm for MB5B .This report already programmed to call a report in background.It takes stocks for given period,I am taking the values using "import memory-id" statement.It gives an error log in SM37 as:
Choose at least one scope of list
Message no. M7829
Can we call a submit stmt in a report that is to run in background?? or pls provide any alternative for this problem??
Thnax & Regards
Sonal

Hi Sonal,
1. This is happening because there are some checkboxes on the selection screen
   which are ticked by default when we run in fore ground
   and are blank when run in background.
Hence the system gives the error meaning to select atleast one of them.
2. We can simulate this error in foreground also.
   There is one button on selection screen in the middle frame.
   "> Category"
   Just push it.
   Some checkboxes will appear now.
   Untick all of them and run the report. You will get the same error
Choose at least one scope of list
3. So while doing SUBMIT in the z report, you can pass the values of those checkboxes (which ever you require) as 'X'.
eg.
report abc.
submit RM07MLBD
with matnr = '3'
with pa_wdzer = 'X'.
4. The checkboxes field names are:
PARAMETERS : pa_wdzer    LIKE AM07M-MB5B_XONUL
                          modif id liu.
PARAMETERS : pa_wdzew    LIKE AM07M-MB5B_XONUL
                          modif id liu.
PARAMETERS : pa_wdwiz    LIKE AM07M-MB5B_XONUL
                          modif id liu.

PARAMETERS : pa_wdwew    LIKE AM07M-MB5B_XONUL
                          modif id liu.

Query SQL code gets deleted after export to Excel. "Query must have at least one destination field"

Hi all,
I'm getting really frustrated by this Access error. It happens when I export the result of a query through an Access macro to Excel, the first time it runs well but the next time, there is a chance that the query won't run and the error "Query
must have at least one destination field" will be displayed. After that, I try to check the query SQL code and discover the code has vanished. I'm using simple Select query without joins, only "where", "group by" and "order by"
statements.
Thank you in advance for your help,
Jesus
Edit:
One of these queries are like the following (all of them are of this type):
SELECT Field1, field2, field3, field4, field5, Sum(Field6) AS SumOfField6, Sum(Field7) AS SumOfField7
FROM Table1
WHERE Field6 is not null
GROUP BY Field1, field2, field3, field4, field5
Order By Sum(Field6) desc

Hi Peter,
Thank you for your response, I updated the original question with one of the codes.
Thanks,
Jesus

Burn CD: must contain at least one track-error

In Waveburner, when I click burn CD I get an error: "A project must contain at least one track"
I selected 8 tracks in my saved project and clicked Burn CD. I did the same unselected.
I get the same error every time. Why?
W.W.

Thank you kcstudio for responding.
In the meantime I figured out why I was getting this error. Although I don't understand why I even got this.
The existing 8 tracks I imported with Import from the desktop into this WaveBurner project. Working in Regions tab all the time I did not realize that when I switched to the CD tracks tab there was nothing there. No regions and title list. So I made a new project and imported the audio files again making sure the CD tracks tab was selected refore. After that regions and listings were there both in regiones and CD tracks tab. I think Import
should have taken care of that. I don't get it why there was nothing when I clicked the CD track tab.

CHILD form error FRM-30100: Block must have at least one primary key item.

Hi friends,
I have increased the DML array of the child block from 1 to 10, but it throws me error:
FRM-30100: Block must have at least one primary key item.
Block: CEC_ADJUSTMENT_RECON
Form: CEC_ADJ
FRM-30085: Unable to adjust form for output.
How does a form know that the table does not have primary key? Is it referring to it?
Thanks a lot

I dont understand why do you increase the DML array size..
Because it says in the HELP
Specifies the maximum array size for inserting, updating, and deleting records in the database at one time.
A larger size reduces transaction processing time by reducing network traffic to the database, but requires more memory. The optimal size is the number of records a user modifies in one transaction.
The FRM-30100 comes not because of the above property..
If your query data source type is other than TABLE, it is a must to set at least one database field's PRIMARY KEY ITEM PROPERTY in the block to be a YES.

The library must contain at least one event

Hello everyone. Noob question here.
How do you delete event in "All Events"? when i try to do so, it says "the operation cannot be completed. the library must contain at least one event"..
Please, pretty please answer..
Thank you so much.

iMovie version 10 uses Libraries to store your data. This date is stored inside of Events. You can think of Events as folders.
Events can contain clips and other media as well as Projects.
Each Library must contain at least one Event.
So the short answer to your quest is that you cannot delete because it is the only Event in the Library.
You can delete clips and Projects that are in that Event.
If you can describe the end result you are trying to achieve, I may be able to offer some suggestions.

Mauricio,
I think this is an old console error in creating this mbean. The
WTCtBridgeRedirect
is mistakenly defined under the scope of the WTCtBridgeGlobal mbean
where it should be at the same level(ie a child of the WTCServer mbean).
The WTCService expects to find it as a child of the WTCServer mbean and
throws the exeption when it doesn't see it.
I think the fix is to edit the config.xml and move the termination for
WTCtBridgeGlobal("</WTCtBridgeGlobal>") to before the declaration
of the WTCtBridgeRedirect.

Error: Find criteria must contain at least one sort field value.

Hi
I am getting the followng error in Sort.as when I click on a column in a DataGrid that is bound to a nested property (e.g. parent.name)
Error: Find criteria must contain at least one sort field value.
I can see why this is failing.
In the findItem function of Sort.as the code tests whether there is data in line (456) hasFieldName = values[fieldName] !== undefined. This fails and so an error is raised later in the function by:
     if (fieldsForCompare.length == 0)     {
     message = resourceManager.getString("collections", "findRestriction");
          throw new SortError(message);     }
The code needs to traverse down the object hierarchy to get the field so that error is not thrown .
The code needs to traverse down the object hierarchy to get the field so that error is not thrown .
In the case of a non nested property, everything works fine.
There is lots of discussion about nested properties in DataGrid and there is this jira:

There is talk of using a labelFunction or an itemRenderer and other third party solutions (extensions of DataGridColumn).
Is this a bug? is there a workaround using labelFunction or itemRenderer which can stop the error in Sort.as?
James
Here is the code of findItem in Sort.as of SDK 3..4.0.9271
public
function findItem(items:Array,values:Object,
mode:String,
returnInsertionIndex:Boolean =
false,compareFunction:Function =
null):int{
var compareForFind:Function;
var fieldsForCompare:Array;
var message:String;
if (!items){
message = resourceManager.getString(
"collections", "noItems");
throw new SortError(message);}
else if (items.length == 0){
return returnInsertionIndex ? 1 : -1;}
if (compareFunction == null){
compareForFind =
this.compareFunction;
// configure the search criteria
if (values && fieldList.length > 0){
fieldsForCompare = [];
//build up the fields we can compare, if we skip a field in the
//middle throw an error. it is ok to not have all the fields
//though
var fieldName:String;
var hadPreviousFieldName:Boolean = true;
for (var i:int = 0; i < fieldList.length; i++){
fieldName = fieldList[i];
if (fieldName){
var hasFieldName:Boolean;
try
hasFieldName = values[fieldName] !==
undefined;}
catch(e:Error){
hasFieldName =
false;}
if (hasFieldName){
if (!hadPreviousFieldName){
message = resourceManager.getString(
"collections", "findCondition", [ fieldName ]);
throw new SortError(message);}
else
fieldsForCompare.push(fieldName);
else
hadPreviousFieldName =
false;}
else
//this is ok because sometimes a sortfield might
//have a custom comparator
fieldsForCompare.push(
null);}
if (fieldsForCompare.length == 0){
message = resourceManager.getString(
"collections", "findRestriction");
throw new SortError(message);}
else
try
initSortFields(items[0]);
catch(initSortError:SortError){
//oh well, use the default comparators...
else
compareForFind = compareFunction;

I have tried a sortCompareFunction:
var sort:Sort = new Sort();
sort.compareFunction = compareFunction;sort.fields = [sortField];
data.sort = sort;
data.refresh();
this makes no difference.
