Validation in adf

can we defined order of execution of validation rule if yes then how
Edited by: 902943 on Dec 17, 2011 3:25 AM

Hi,
You can define custom validation by passing component.If error is occurred validation will trigger for that component in defined order.
//pseudo code for validate messages
public void validate1(UIComponent,Error) {
return;
public void validate2(UIComponent,Error) {
return;

Do we have any tab out validations in ADF?

Hi Everyone,
Do we have any tab out validations in ADF?
After entering something in the text field and Immediately after coming out of the text field can we perform some validations?
Is this possible in ADF?
If yes, then how?
Any suggestions will be really useful.
Thanks.

Hi Kumar,
These are the steps to implement below behavior.
1) Jsff - Have auto submit on your field.
2) Jsff - Have action listener on the component.
3) Backing Bean - inside backing bean action listener method you need to get the entered value in the field.
See below peice of code to get the value in backing bean.
FacesContext facesContext = FacesContext.getCurrentInstance();
ExpressionFactory expressionFactory = facesContext.getApplication().getExpressionFactory();
DCBindingContainer dCBindingContainer = (DCBindingContainer)expressionFactory.createValueExpression(facesContext.getELContext(), "#{bindings}",
DCBindingContainer.class).getValue(facesContext.getELContext());
DCDataControl dCDataControl = dCBindingContainer.findDataControl("<DataControl name>");
<application module name>AMImpl am = (<applicationModule name>Impl)dCDataControl.getApplicationModule();
ELContext elctx = facesContext.getELContext();
ValueExpression vel1 = expressionFactory.createValueExpression(elctx, "#{bindings.<ui field name>.inputValue}", String.class);
here call your am method.
4) Inside your AmImpl method, implement dynamic where clause.
see below piece of code for dynamic where clause implementation.
ViewObject ob = this.get<VOName>();
ob.setWhereClauseParams(null);
ob.setWhereClause("<COLUMN NAME> = :1");
ob.fiscalDocumentChargeAssocVO.setWhereClauseParam(0,<value we get from UI field>);
ob.executeQuery();
5) Have partial trigger on your result table. partial trigger should be your ui filed id.
Hope this will help you.
Thanks,
Dileep.

Number Validation in ADF-BC

I am using JDeveloper 11.1.1.4 and ADF-BC in my project.
In one of my pages,I display a table and a panel form for the table rows in my page.
In my panel form I have two fields ex:minAge and maxAge.
On change of row/save I need to display a validation message that minAge should be less than maxAge.
I tried using EntityLevel atrribute validation -- > Compare rule with less than Viewobject attribute.
But this is not working and it is always compares with first row's value only.
How is this type of standard validation implemented in ADF-BC projects.
Please suggest..
Thanks,
Praveen

Field level Validation in ADF

Hi,
We have some forms and we want to implement validation on field level. Means, as soon as i enter a value and move to next field, if the value entered is not as per desired regular expression than it should show the error. What i am trying is applying validator attribute on inputText and setting auto submit to true. It is working but some times page suddenly refresh itself and then the validation don't work.
Also one validation is to match the passwords (new password and confirm password). If i am using above method i am also not able to get the correct value of new password to match eith confirm password.
Can someone please suggest whats the right way to implement this functionality in ADF.
I am using jDev 11.1.1.4 and using Placeholder data control.
Please suggest
Thanks

If <af:validateRegExp> meets your requirements then sure, use it. The neat thing about the default validators will do both client side and server side validation. As such bypassing the JavaScript validators by sending raw HTTP requests to your server will still result in the required validation being applied via the server side.
For cross field validation, that's most easily done at the JSF bean level. It will require a round trip to the server to perform the validation though (rather than just validated at the client level). Is that an issue? There's an alternative solution but if you're not worried about round trips, go with the simple solution.

How to set client side validations in ADF Forms

check for client side validations on submission of a form and display custom error messages.

Hi,
you really should take more time in phrasing out a question. I have no clue of what you are actually asking for. Note that ADF Faces performs client side validation e.g. for required fields. Just in case this was the question

ADF validator or JavaScript for client side validation ?

using JDev and ADF 11g
Problem description : To apply validations such as date range check, pattern matching, maxlength etc.. on ADF Faces Components.
Solution 1: Use ADF validator such as Reg Expr validator, Max Length validator
Souliton 2: Write Javascript code for validating the component's value at cleint side.
When using ADF Validator for such type of validation checking, a request is send to the server for processing (additional overhead) . However we can do such validations with javaScript functions without the need to interact with the server. So, what benefit does ADF Validator serves when one needs to implement such validations ?
Please share your views...

H,
afaik, client side validation in ADF Faces suppresses server round trips if a validation error is detected on the client. Only if no problem is found, the server side validation is challenged upon submit (so no extra round trip for validation). Shay is absolutely correct. JavaScript is a convenience but never a solution.
Here's how to create a custom validator with a client and server side implementation : http://download.oracle.com/docs/cd/E15523_01/web.1111/b31973/af_validate.htm#BABEIIDD

ADF Faces: Dynamically enabling / disabling client validation

Hi Frank,
Im using JDeveloper 11.1.1.2.0 version. I want to disable the client side validation for some condition. I have read related information from Frank blog .
But In that frank used adf-faces-config.xml file for the following configuration.
<adf-faces-config xmlns="http://xmlns.oracle.com/adf/view/faces/config">
<skin-family>oracle</skin-family>
<client-validation-disabled>true</client-validation-disabled>
</adf-faces-config>
But in my application, I could not find adf-faces-config.xml file. I dont know where to configure please provide me the information.
Regards,
Felix

Hi,
in JDeveloper 11g this no longer is an option. To disable client validation you set immediate=true on the UI component, which youalso can do dynamically. Howerver, ensure you refresh the component after changing the immediate property state.

Validation at transection level

Hello Gurus,
I am new in adf and using jdev 11.1.2.3.
We have the option to validate business rules at attribute level and row level, but my requirement is i want to validate at transaction level. Mean if user has added four rows i want to validated theses four row simultaneously before commit changes to database. For example i have a vo in which user is entering data. i want when he entered all the data i want to loop through all records which he entered and then if validation is paased then will save changes to db.
Please advice how can i do this in adf.
Thanks,

ADF does not have direct built-in method(s) for this purpose. Declarative Enitty validators have an option to "Defer execution to Transaction level" (have a look at the "Validation Execution" tab of the "Edit Validation Rule" dialog). However, Entity validators are not suitable for validating multiple Entity instances together.
The recommended way to implement validation among multiple Entity instances is to override the EntityImpl.beforeCommit() method. Have a look at subtopic 8.5.2 here:
Implementing Validation and Business Rules Programmatically
If you follow this alternative, do not forget to set a required system property in order to avoid unexpected side effects:
Decompiling ADF Binaries: Throwing ValidationException from the beforeCommit() logic !
The alternative of overriding the ViewObjectImpl.beforeCommit() method is not recommended. Have a look here for explanation:

Adf-Struts/JSP/BC4J- and setting date fields from jsp

Hi,
I'm working with the new ADF Frameworks (JDev 9.0.5.1) and ran into some questions regarding exception handling using BC4J, Struts and JSPs.
I have a DATE column in database and an entity and VO with a datefield with type oracle.jbo.domain.Date.
My JSP shows a textfield and the user should enter a valid date. Everything fine, until date is of wrong format or contains illegal characters...
Problem:
ADF tries to do a setAttribute on the datefield in VO row which expects a parameter with type oracle.jbo.domain.Date. When the user entered e.g. "NiceWeather" as date, I get an IIlegalArgumentException while converting to the correct Date format. This exception isn't thrown by bc4j as AttrValException and therefore my JSP renders a global error instead of a message directly behind the date field.
I tried to validate the datefield in my DataForm and in my Action in the validateModelUpdates() method, but with no fitting solution.
Any ideas how to validate a datefield with adf/struts/jsp/bc4j?
Thanks for your help!
Torsten.

Torsen - In the first instance I'd recommed that you try and handle it declaritively using the Struts Validator Framework . See http://otn.oracle.com/products/jdev/howtos/10g/StrutsValidator/struts_validator_howto.html
There is a section in there on how to use the validator with ADF databound pages and you can check the format the user enters via generated JavaScript.
Also check out the matching sample project:
http://otn.oracle.com/sample_code/products/jdev/10g/ADFandStrutsValidator.zip - this has a data field check on it as well

How to skip validation using serverListener

Hi,
I am using Jdev 11.1.2.3.0
My requirement was to called some action using the keyboard key.
I tried with Access key first but its behaving differently in different browser.
Crome: allowing action on access key press.
IE : setting the focus on commandLink.
Note : I have defined accessKey for RichCommandLink.
Then i used the different approach which is as follows:
1- Register the keyBoard handler to document. on beforePhase Event.
2- Added the js file as follows :
Javascript file:
var keyRegistry = new Array();
keyRegistry[0] = "alt 1";
keyRegistry[1] = "alt 2";
keyRegistry[2] = "alt 3";
keyRegistry[3] = "alt 4";
keyRegistry[4] = "alt 5";
keyRegistry[5] = "alt 6";
keyRegistry[6] = "alt 7";
keyRegistry[7] = "alt 8";
keyRegistry[8] = "alt 9";
keyRegistry[9] = "alt 0";
function registerKeyBoardHandler(serverListener, afdocument) {
_serverListener = serverListener;
var document = AdfPage.PAGE.findComponentByAbsoluteId(afdocument);
_document = document;
for (var i = keyRegistry.length - 1; i >= 0; i--) {
    var keyStroke = AdfKeyStroke.getKeyStrokeFromMarshalledString(keyRegistry);
AdfRichUIPeer.registerKeyStroke(document, keyStroke, callBack);
function callBack(keyCode) {
var activeComponentClientId = AdfPage.PAGE.getActiveComponentId();
// Send the marshalled key code to the server listener for the developer
// To handle the function key in a managed bean method
var marshalledKeyCode = keyCode.toMarshalledString();
AdfCustomEvent.queue(_document,
_serverListener, {keycode:marshalledKeyCode,
    activeComponentClientId:activeComponentClientId}, true);
// indicate to the client that the key was handled and that there
// is no need to pass the event to the browser to handle it
return true;
*jspx page:*
        <f:view beforePhase="#{KeyboardHandler.registerKeyboardMapping}">
<f:loadBundle basename="properties/Labels" var="labels"/>
<af:document id="adfDocument">
<af:resource type="javascript" source="/js/keyboard.js"/>
<af:serverListener type="keyboardToServerNotify" method="#{KeyboardHandler.handleKeyboardEvent}" />
</af:document>
</f:view>
*Java Code :*
        public class KeyboardHandler {
public KeyboardHandler() {
super();
public void registerKeyboardMapping(PhaseEvent phaseEvent) {
if (phaseEvent.getPhaseId() == PhaseId.RENDER_RESPONSE) {
FacesContext facesContext = FacesContext.getCurrentInstance();
ExtendedRenderKitService extRenderKitService =
Service.getRenderKitService(facesContext,
ExtendedRenderKitService.class);
List childComponents = facesContext.getViewRoot().getChildren();
//First child component in an ADF Faces page - and the only child - is af:document
//Thus no need to parse the child components and check for their component family
//type
String id =
((UIComponent)childComponents.get(0)).getClientId(facesContext);
StringBuffer script = new StringBuffer();
script.append("window.registerKeyBoardHandler('keyboardToServerNotify','" +
id + "')");
extRenderKitService.addScript(facesContext, script.toString());
public void handleKeyboardEvent(ClientEvent clientEvent) {
String keyCode = (String)clientEvent.getParameters().get("keycode");
System.out.println("KeyCode ::"+keyCode);
//Here on basis of numeric key 0-9 i will decide different action
This is working fine and launching the first action successfully.
*Now problem is that when i invoked second action its asking me enter data for required fields.*
If i was invoking serverlistener from button than I can control immediate property of command button. but here serverListener is getting called form document. How can I avoid validation here.
Can anybody please me?
Thanks a lot in advance.

Invisible message in javascript validation

I followed the steps from this tutorial (Using Validator with ADF model bound pages)

Can anynody tell me, where is the problem?
Thanks a lot

Form Validations

How to perform form validations in ADF. And also can i customize the behaviour of "Required" property of a UIComponent? I dont want alert boxes to be shown Can i change that?

you might want to think about using one of the popup LOV item types for your employee ID field. popup LOVs are great for cases where you don't want to weigh your page down w/large lists of values. about your validation, if you really want to do it client-side, then javascript's probably the way to go (search google for code). if you do that, though, let the record show that you'd have to fetch your valid values down to your page for your comparison logic, anyhow. i'd consider using a regular htmldb validation for your emp id field. you seemed concerned in your post with the page submission. i'm assuming that's because you didn't want processing to occur unless the validation passes. if that's the case, fear not, it's a simple matter to set your processing to occur only after your validations have passed. check out the available "Process Point"s and "Computation Point"s for htmldb Processes and Computations to see what i mean.
hope this helps,

Database Adapter VS. ADF-BC

Hello everyone
I've been working with Oracle BPM 11g for quite a while now.
The process I am working on has lots of DB interactions, ie:
-getting user's previous history from the database and show it in their workspace
-user inserts some co-worker's ID, their record is fetched from DB and shown to him on the same page
etc.
What I have figured out so far:
-Database adapter needs less technical knowledge, therefore it's easier to work with.
-ADF-BC provides alot more control but mistakes can happen if one is not completely familiar with it.
-Some issues exist in ADF-BC when working with non-oracle databases, like the one I've mentioned in this thread: Business Rules:Non-oracle db connections not shown in the ADF-BC Facts sect
-Since working with Database Adapter means adding one or sometimes more service tasks to the process, the process can get quite messy and hard to trace if the project is big.
-ADF-BC view objects have a sync mechanism so if there is a change in the database later, less work needs to be done with ADF-BC inorder to make the application compatible with the database. (I'm not completely sure about this one though!)
I've found this section in the book "Oracle Business Process Management 11g Handbook":
>
ADF-BC vs. Database Adapters
BPM also includes a database adapter thaqt can be used to retrieve data from a database into a process. In the context of getting data for displaying as part of a task form or for using as a list-of-values, using ADF-BC is recommended because it provides the following benefits:
-Data currency: If a database adapter is use4d, then the process will need to retrieve the data. This can result in a time lag between when a user interacts with the data and when the process retrieves it.
However, when using ADF-BC, the data can be fetched by the UIj itself, ensuring it is current.
-Business Logic: ADF-BC is much more than object-to-relational mapping. As discussed earlier, it supports business logic like validations, as well as provides hooks for the inclusion of custom business logic.
In the context of a process accessing data from a database for processing (and not for a user interface), working with a database adapter is simpler.
However, using ADF-BC means that business logic is shared between BPM and user interface layers. Therefore, if ADF-BC already exists, or there is a possibility of building user interfaces on top of the data, or there are business logic and validation requirements, ADF-BC shyould be used. Otherwise, a databaser adapter should be used.
>
Since reading this passage, I have moved to ADF-BC and re-created my whole process, replacing the DB Adapters where it applies.
But I have had lots of issues which were not presented before, which makes me wonder: if oracle has provided a tool like database adapter in their BPM, why should one go to all the trouble with adf-bc?
The main problem is, there are lots and lots of sources on the net on woking with ADF-BC and on working with Oracle BPM (well not as much as ADF) separately, but when integrating the two, it's kind of hard for someone new like me to figure out a good strategy to stick to.
Would someone shed some light on the topic please?
Thank alot

Hello
Yes, for example in the facts section of my business rule, on the adf-bc tab, my sql server database connections won't be available, as I've mentioned here:
Business Rules:Non-oracle db connections not shown in the ADF-BC Facts sect
or there's that other issue with the pool connection which I've mentioned in this one:
pool connection issue with sql server database in adf application
or when a new table is added to the database, if one needs to create a new entity object from that, all the attributes must be created manually, or the whole app module needs to be recreated.
Now some of this is probably duo to my lack of enough knowledge, but I didn't have such problems when working with the adapter.
Thanks
