Refresh Datagrid After Popup Data Edit

Hi all,
I'm fairly new to flex development, so please keep that in mind when trying to help... I may ask some really stupid questions!
Basically what I'm trying to do is to refresh the source data of a datagrid ONLY when the popup window that I'm using to add/edit/delete records is closed.
I have successfully captured WHEN the window closes... I can see the event happening in my datagrid component. I used an Alert.show() to prompt me after the popup closes and the datagrid captures the close event.
What I can't figure out for the life of me is how to refresh the datagrid's source data, when that source data is being called & populated from a "parent" component.
How it works is like this...
Search Component (6 drop down menus & 1 text input)
|___Datagrid (displays all records by default, only records meeting search criteria upon clicking the "search" button)
|______Popup window editor (this is called by passing the "ID" of the record I want to take action on into the popup window using a public variable when a user DOUBLE CLICKS a value in the datagrid)
So let's say for instance you are looking at customer A. Customer A's record loads into the popup window... and then let's say you want to delete that record for whatever reason. Currently, when you click the "Delete Record" button in my application, the popup window closes, and from the looks of things, it dispatches the close event properly. (I added an event listener to the datagrid component when I instantiated it in the search component), so when the popup window closes, the event listener fires and I have an Alert to tell me that yes, the close event was dispatched.
I think I know "What" I'm doing wrong, but I don't know how to go about changing it to make it work. Basically because the datagrid is populated IN the search component from an arraycollection, my attempts to "Refresh" the data in the datagrid component which captures the close event of the popup window won't work because the datagrid component has no visibility to the arraycollection used in the search component to populate said datagrid component.
I know that the record is being deleted, as if I actually click the "search" button again, the record does disapear from the datagrid. How do I force that to happen automagically when the popup form closes?
I can provide a code refernce if I need to... gonna take a bit though as alot of what I've built has references to client's data which I'd have to remove.
If anyone could provide some insight here, or a direction I would appreciate it. I've looked at a number of solutions so far, and I've not had luck with any of them.

Refresh LOV after inserting data in correspondent table

Hi all,
I am using Jdeveloper 11.1.1.2 and ADFBC.
I have a page with a table (tableA) with some fields. One of them has a LOV associated to another table(tableB). I have a button (button1) that shows a popup(popup1) and opens a new task flow with a fragment to insert data in the tableB.
After inserting/modifying rows in tableB and after pressing commit (property: end-transaction) or rollback buttons (property: end-transaction and restore save point), LOV does not refresh.
I have tried to set the property partial triggers of the LOV to button1 or popup1 and it does not work.
How can I solve it?
Thank you.
Andrea

How about VO for table B ? Did you refresh that ? I didn't use the same VO for table & LOV.
so in "List data Source" -- VO -- I am using "SQL statement" and statement includes fields from Table B and Table A.
VO for LDS using "Rows populated by a SQL query with read-only access". I didn't use "Updateable Access through Entity Objects".
Sample of VO of LDS:
select A.model_number modelNumber, a.part_number partNumber, b.MODEM_TYPE ModemType
from table A a,Table B b
where a.PART_NUMBER_ID = b.PART_NUMBER_ID
and a.part_number_id =:partID

Adf refresh table after popup

I have a search page with a deep link to a page showing detailed information about the selected search result. From the detail page I open up popups to enable the user to change some of the data. When returning from the popup the detailed information is not refreshed. To fix this I have added a backing bean and calls it from the returnListener.
The problem is that the detailpage does not show the changed data. If I call the popup a second time and then just exit it the detail page then finally shows the changed data.
Any idees on why this happens ?
In the logg I get

How-To "Refresh a table of data after inserting or deleting"

I'd like to say a word on the how-to article "How to refresh a table of data after inserting or deleting a row using ADF".
(http://www.oracle.com/technology/products/jdev/howtos/1013/updtable/index.html?_template=/ocom/technology/content/print)
I spent a lot of time on it because I needed help in implementing simple CRUD functionality on a table, using JSF-ADF-TopLink technologies.
While the the article does provide correct steps, it is in one important place not specific enough, so the reader may easily get stuck. In section "Refresh the data table", point 1: when you double click on the removeEntity() button, in Structure window, then you do not get the required dialog. You get CommandButton Properties dialog.
You must click on the removeEntity() button in Editor's Design view. But even there you may get the CommandButton Properties dialog, not managed beans dialog.
You may resolve that by going to JSF configuration file, faces-config.xml, and switch to Overview view. This will show you the managed beans that you have.
Then, you may already have a backing bean for the page. You can use that and avoid creating a new managed bean.
I could understand what the operations mean only after very careful reading of "Creating More Complex Pages", section "Overriding Declarative Methods" in JDeveloper Help (or in ADF Developer's Guide PDF document).
In general: I believe that "ADF bindings" need more conceptual explanation, maybe in form of an article. Grammatical form "bindings" may create a false understanding that "bindings" are just references. But they are not -- ADF bindings are active objects that handle traffic between UI components and Data Controls. It seems that "bindings" even communicate among themselves. Maybe it would be more understandable to differentiate strictly between "binding objects" (or "binders"?), binding object definitions and binding object references.
It would be very helpful to have a diagram showing grahically what specific binder objects are created in a small apllication (2-3 pages using 1-2 tables), with whom they communicate and what type of data is passed on.

Hi
Thanks for your infos.
Yes exactly I use almost the same code you have post here.
Could You answer to my next questions?
First - >what do you mean by saying that "it's not good idea using refreshing in IE?" Of course I use refreshing in backing_bean for my button "remove" that removes row, commit changes to database and refresh table, almost the same as You said in your post:
Code in backing_bean is and comments on difference to Your code is below:
public commandButton2_action1(){
BindingContainer bindings = getBindings();
OperationBinding operationBinding =
bindings.getOperationBinding("removeEntity");
Object result = operationBinding.execute();
if (!operationBinding.getErrors().isEmpty()) {
return null;
//above remove entity, but I dont now if it do commit to database? So i do it below
OperationBinding commit1 = bindings.getOperationBinding("Commit");
commit1.execute();
//and at the end I refresh my table, "findAllRezerwacja1 - it is an id of the methodAction, not the iterator -> is it ok? or should I change to Iterator id?
OperationBinding requery = bindings.getOperationBinding("findAllRezerwacja1");
requery.execute();
return null;
Page Definition code for this:
<methodAction id="findAllRezerwacja1"
InstanceName="SessionEJBLocal.dataProvider"
DataControl="SessionEJBLocal" MethodName="findAllRezerwacja"
RequiresUpdateModel="true" Action="999"
ReturnName="SessionEJBLocal.methodResults.SessionEJBLocal_dataProvider_findAllRezerwacja_result"/>
<table id="findAllRezerwacja2" IterBinding="findAllRezerwacja1Iter">
<AttrNames>
<Item Value="dataDo"/>
<Item Value="dataOd"/>
<Item Value="idRezerwacja"/>
<Item Value="liczbaUczestnikow"/>
<Item Value="prowadzacy"/>
<Item Value="uwagi"/>
</AttrNames>
</table>
<methodAction id="removeEntity" InstanceName="SessionEJBLocal.dataProvider"
DataControl="SessionEJBLocal" MethodName="removeEntity"
RequiresUpdateModel="true" Action="999">
<NamedData NDName="entity"
NDValue="${bindings.findAllRezerwacja2.currentRow.dataProvider}"
NDType="java.lang.Object"/>
</methodAction>
<action id="Commit" IterBinding="findAllRezerwacja1Iter"
InstanceName="SessionEJBLocal.dataProvider"
DataControl="SessionEJBLocal" RequiresUpdateModel="true"
Action="2"/>
</bindings>
//and rest of code for Iterator etc
My second question is, why when you use refresh button in IE (I know is not recommended as You said, but sometimes user do it, so I want prevent situations that I will describe here) so when I press refresh button in IE exactly after removing one row by clicking my button, refreshing by pressing IE button is doing the same --> is deleting next row. How to stop deleting row, when for example user would press IE refresh button after pressing remove button for table. If I change selection in table after deleting row, and press refresh button in IE, instead of deleting row, I got error message: JBO-29000: JBO-35007: and
JBO-35007. So where Im doing wrong. Maybe I should do sth with postback ? Could You help me? Thanks in advance
Last one question: what is the difference between using delete and removeEntity from operations node? Im now reading carefully ADF Dev Guide, so I hope I can find infos there? But if You know, please answer to this question.
Thanks

DataGrid jumps on data refresh

Hi,
I have a datagrid control bound to an arraycollection. I also
have a timer which updates the arraycollection with new data and
call its refresh method every few seconds
The problem is that the datagrid scrolls to the item that is
selected and it looks very jumpy. How can i prevent this from
happening?

Actually, I discovered that I don't have to use itemUpdated()
method when binding an arraycollection to a datagrid (notification
of data change is sent to the view automatically)...
What i did instead was simply update the properties of the
objects inside of my arraycollection through a loop.
for(var i:int = 0; i < mainCollection.length; i++){
var item:Object = mainCollection.getItemAt(i);
for (var qs:String in anotherCollection
item[qs] = anotherCollection[item.id][qs];
mainCollection.itemUpdated(item);
But, since you are ADDING or REMOVING items, I'm not sure how
useful the code above will be in helping you figure it out. Since I
use it to update the items.

Creating new row right after popup opens (JBO-35007 because of trigger)

Hi,
I have the same popup (with an ADF form) to add and to edit data. But i have two buttons which displays this popup - Add new and Edit, Edit works OK, on add, i insert new record like this:
        DCIteratorBinding dciter =
            (DCIteratorBinding)bindingContainer.get(iterator);
        ViewObject view = dciter.getViewObject();
        Row newRow = view.createRow();
        view.insertRow(newRow);
        view.setCurrentRow(newRow);before popup is open. And it adds a new record. But the record has id -10 (or some other negative number). This -10 is shown on calling page (the page from which the popup is open) in ADF ReadOnly table as -10 as id and other cells in row empty. That shouldn't happen (se bellow why). User then edits empty form in popup, and commits - then i get JBO-35007 because -10 changed to 123 - because of trigger.
I tried to requery - it doesn't help, see Refresh after pop-up window closes.
Can you suggest a solution on how to create a row right after popup opens?
Also,
i create new record on button's LaunchListener method. This method seems to execute before popup is open and so it affects the calling page also. I think the problem would be solved if new row would be created after popup is opened, not while opening it. (clicking create in popup works fine)

in my real case, i usually don't show ids; but to simplify debugging, i created test project where i show as many things as possible.
you mean, creating new record like following?
        bindings.getOperationBinding("Create").execute();I don't use that because i don't get empty fields in popup window (although new record is created). Actually, i don't know how to set this created record to be selected one. Suggestions?
And I did some more testing, if I create new record with clicking on Create (not creating new row automatically), i get JBO-35007 only if there was selected any other than the first row in table.
and i tried to move create method binding in pagedef, so it's the first one.. But it seems like there is no effect.
btw, i found this in one of examples on web:
   <invokeAction Binds="Execute"
                  id="refreshTableViewObjectAfterAddingNewApp"
                  Refresh="prepareModel"
                  RefreshCondition="#{processScope.addedNewApp}" />refresh condition must be true when adding new row and false for everything else. I'm not sure what that does, but it seems to work... :)
I really shouldn't use the same View Objects in popup and 'master' page, should I?

How to lock a pdf form after entering data

Hi
I have created certificate with editable fields for a client, I was of the thinking that the certificate is to be filled-in and printed however the client informed me that it is instead emailed to recipients. How can I make it possible for the client to lock the certificate after entering data.
Bear in mind that the client is using Adobe Reader not Acrobat. I have tried setting a security password but Reader does not require the password in order to enable or disable the fields.

If the user has Acrobat, not the free Reader, they could flatten the PDF form. If they only have Reader they can make the fields read only. They also might want to use a digital certificate to invisibly sign the PDF. Signing the PDF will add code to disclose if the PDF has been changed since it was signed.

How to remove mandatory field for Last Name in Personal Data Editing Screen

Hello All,
CUrrently we are using BP_ ERP5ESS1.31 SP5 & SAP_ESS 603 SP5.
All my ESS Services are Displaying fine and working from Portal.I am having the requirement like I need to make Last Name as Non-Mandatory field in Personal Data. While Editing the PD Screen, there i will find the * mark for Last Name filed, i checked through the Global Personalization Make as Mandatory is Not Personalized its showing, i think its defualt prpoerty,so i am unable make any changes from Portal w.r.t Global Personalization.
I checked in SPRO-- Personal Admin> Custmomizing User Interfaces>Change Screen Modifications, there i find the respective Module pool for those Infotypes and country Specific..
I cheked forModulePool MP000200--> P0002 and Variable Key-40(For India) P0002 - NACHIN -- LastName only OF Radio Button is Selected all other Rado buttons are not selected.
I Checked in V_T588MFPROPS view there for 0002 Infotype P0002 -- NACHN Mandatory check box is Checked all other check boxes are Unchecked.
How to make that Last Name field as Non-Mandatory in Personal Data Edit Screen, where i need to make the changes.'
Please list out the Steps..Where i need to do the configuration. And i assigned all the required ESS roles on the backend.
Thanks in Advance
Adapag

Hi,
I don't think supressing through Global Personalization will change the business logic. Within the Business Logic it checks for the mandatory field.
After the changes I guess you need to make the changes accordingly.
The below link might be of some help.

How to make Birth date field (GBDAT) under IT0002 Personal data editable

Hello Consultants,
We had initially Birth date field (GBDAT) under IT0002 Personal data editable ...But after upgrade is made non editable...
We want to make it editable again..
Kindly suggest how we can proceed abt this....

Hi Anju,
1. Go to PA30 >> Infotype 0002 >> On Date of Birth Field >> Enter F1 and find the Technical Parameter and idenfity which Screen is being Used... say for Eg: MP000200 / 2010
2. Go to Feature P0002 in PE03 and then identify the Return code for the Molga and Co. Code.
This Return feature is nothing but the Variable Key. Say for Example: 10
3. Now Go to SM30 >> T588M.....
3. Idenfity the Screen that you found in the step 1 and Variable Key you found in Step 2.
i.e. MP000200 / 2010 / 10
5. Double Click on that record and Find the Screen Field P0002-GBDAT... this has been set to Output Field... change it to Standard and it will work.
Hope this helps !!!

Restrictin GR after delivery date

Hi,
I want to make the setting such that user should not make the GR if material received after the Delivery date in the PO, so is there any setting for this.
regards,

Hi ,
I think this should solve this issue ,
While creating PO under Delivery tab >>> Set >> Latest GR Date and use M7163 as error
Info from SAP Note 856279
Fill the date field for the 'Latest Possible Goods Receipt' (LEWED)
in the purchase order item. If you do this and you enter a GR
document after this date, the system issues message M7163, which
you must set as an error message in Customizing.

Refreshing components after action

Hello, today i have a next problem:
I have TreeView which contains rekords from SQLite database and Dialog, which adding records for SQLite database. But when i'm adding a new record to db i must restart application to get a new added rekord in Tree. Situation looks the same for PieChart and label.
It is any way to refresh TreeView after adding somethink to db?
I need refresh too label and PieChart.
Can someone help mi in this situation?
Greetings!

If the database is being updated from outside of your application, then it can be difficult or impossibile to keep your application completely in sync with the database. If the database has a mechanism for notifying external applications when changes are made, then you could program your application to hook into that; that's really a question about your database engine, and not about JavaFX.
Otherwise there are really two choices: have a "Refresh" button in your application, or poll the database at regular intervals and refresh automatically. In either case, you can just invoke the same code that you use to build the tree from the database in order to refresh the tree. You might want to add some (likely fairly complex) logic to maintain the expanded state and selection of the TreeItems. You could also retrive the data from the database and compare it to what's displayed in the tree, making changes only where necessary (this would, in theory, be more efficient at the expense of more complex code).
In applications I write, I simply try to avoid this situation completely. In large, distributed applications, where multiple actors access the same database, on option use a JEE interface to the database and make all database access pass through that. The JEE DAO can then be coded to notify any live actors that need to be in sync with the database when changes happen. This is a large undertaking and requires in-depth knowledge of JEE.

Why these key figures roll up but others do not after the data load

Experts,
I have 7 key figures on target cube, which all are direct mapping from source cube. After loading data from source cube to target cube, 4 of the KFs got auto rolled up by themself, but the rest do not. For example, on source cube, one student record, id is 1002345, has the following KF values to represent the 7 KFs: 3.417, 3.411, 7.346, 3.00, 131.00, 383.00, 90.00. When loading to target cube, there is update rule to get other more information for target record as well. After the load finish, each student has 5 records now. The first 4 KFs has been changed to 3.417xN, 3.411xN, 7.346xN, 3.00xN on the target cube, in some of the 5 records, which are not true for the requirement.
Here are my questions:
1) Since all KFs are direct mapping from soure, why they got changed?
2) Why only some of them change, and some of them do not?
Thanks,
Linda

Thanks by pointing out the way to check. Yes, I checked under RSD1 and foundout the difference between the first 4 and last 3.
The first 4 KFs aggregation is SUM, which needs to change to MAX. But even under edit mode, I can't change the aggregation(disable). So how can I change these 4 KF's aggregation?
Thanks,
Linda
