ADF UIX MultipleSelection - Retaining Values

Can anybody provide a working code snippet which retains rows selected and data entered in a multiple selection UIX component, after doing a page refresh or page submit. Using JDev 9.0.5.2.
Thanks

ADF UIX: Get value in LOV messageList.

I have a messageList that bind to a vo but when I call getTxtCodeCat method from the Struts form bean in Action Class, it does always return me a list index (0,1,2...).
<struts:messageList model="${data.protecteddoc_GN_GnCodeSetupUIModel.CodeDescription}" name="txtCodeCat" prompt="[Code Category]" styleClass="DropdownMedium" required="yes" size="1">
<contents childData="${data.protecteddoc_GN_GnCodeSetupUIModel.CodeDescription.displayData}">
<option model="${uix.current}"/>
</contents>
</struts:messageList>
Please advice how do I retrieve the value instead of index from the LOV?

ADF UIX: LOV searchText contains wrong value (maybe it is a bug)

I'm developing a WEB-application using ADF UIX.
I'm using JDeveloper 9.0.5.2 build 1618.
I've created a form with a messageLovInput field.
If I type e.g. Veszprém into the input field the content of the searchText parameter seems wrong. The URL is http://bela:8988/szszr/_ui.uix?_t=fred&enc=UTF-8&_minWidth=750&_minHeight=550&configName=BaseUIPBCfg1&contextURI=/szszr&redirect=/szszr/telepulesekLOV.do&source=levCimTelepules&searchText=Veszpr%C3%A9m&event=lovFilter
And the value of the searchText string in the lovFilter event is
[0] 'V' 86
[1] 'e' 101
[2] 's' 115
[3] 'z' 122
[4] 'p' 112
[5] 'r' 114
[6] ' ' 65533
The interesting thing is that the final letter (m) is missing from the string!
If I write Veszprém into the search field of the listOfValue and I press the Go button I get the right value in searchText.
The web.xml contains the following part:
<filter>
<filter-name>ADFBindingFilter</filter-name>
<filter-class>oracle.adf.model.servlet.ADFBindingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>

</init-param>
</filter>
The encoding of the UIX pages is windows-1250.
Any help is appreciated,

Display CLOB value in multiple rows in ADF UIX

Hi,
I have an ADF UIX application that uses data that are stored in a CLOB column in an Oracle Database.
The table data is presented in a simple table in page1.uix, I use BC4J for accessing the Database and Oracle JDeveloper 9.0.5.2.
The problem is that the CLOB data appear properly (meaning the rows appear OK) only in a frame (messageTextInput element) of a predefined size and if I change the element into a styledText or a formattedText the frame will not appear, but all the CLOB characters appear in a single row.
Does anyone know how I can present the CLOB text data in a UIX page, without having a frame around the text, and at the same time keep the CLOB text in multiple rows?

There's no completely trivial way. You'd have to do a bit of extra processing of your CLOB data. The most straightforward work to do is to convert "\n" into "<br>", and then pass that into a <formattedText>.

[ADF-UIX] passing selected items to a custom method, how?

Hi,
ADF-UIX can be tricky, and im stuck atm building some functionality, I hope
someone here can point me in a good direction
I have a multipleSelection table filled with data from a ViewObject. I also
have 2 MessageChoice components also filled with data from 2 ViewObjects.
I made a custom method in my AppMod accepting 3 params and dragged that method
on to a DataAction. And I have a submit button calling the DataAction.
Now comes the tricky part, how can I pass the selected rows (radiobuttons) and
the selected items from my MessageChoices to my custom method.
I know I have to change something in paramNames[0].value but what exactly, specialy
the multiselect from my table.
Thanks in advance for any tips :)

"what's the application module"
JDev 10.1.3 leverages an Application Development Framework (ADF) that you can learn about here: http://download-east.oracle.com/docs/pdf/B25947_01.pdf
Specifically, you'll want to look at chapters 2, 4, & 8 in the developer's guide to understand the framework and to understand how to use application modules to call service methods from a JSF page. You can also search this forum as there are other threads discussing this topic, but I'd recommend reviewing the developer guide first.
This article I also found helpful:
http://www.oracle.com/technology/products/jdev/tips/muench/mostcommon/index.html
From my (short) experience, I've learned that you can call methods either using a bean or service methods on the Application Module. Since I am using ADF Business Components (BC), I try to implement any methods that interact with the BC's (view objects, etc.) as service methods on the Application Module (AM). If my method needs to purely implement logic related to the UI or Navigation, then I implement a method on a bean. The other case where I implement a method on a bean is if I need to do some pre-processing (i.e., gather info. about the state of the UI) prior to calling a service method on the AM (an example of this can be found in the dev guide related to the tableSelectMany component) - so there are some cases where the bean method will call a method on the AM - but again, if the method will update the model I try to use a method on the AM to accomplish this. Understanding the ADF framework is the first step (see the dev guide), and then I'd recommend looking at the SRDemo and previous posts on this forum.
Finally, one thing that is really cool - if you define a service method on your AM, it shows up in the data control pallette - you can drag and drop the method on the .jspx page and all of the bindings/wiring is done automatically for you (including handling passing of parameters.)
hope this helps.

One immediate thing: "EA6" is in the tag library namespaces, but you're using EA12.
In general, there've been a lot of changes between EA6 and EA12, but the changed namespace is one simple thing.

ADF-UIX- How to populate multiple input fields from an lov?

Like in Forms Developer where using an LOV we can populate multiple tex input items on selection of a value from the LOV, is it possible for us to do the same in ADF UIX.
Iam usiing JDeveloper 10.1.2

Have a look at this previous post:
Re: Can return messageLovinput more than one value?

ADF UIX doSelect override with PL/SQL fails to allow insert

I've been trying to create an ADF-UIX web app for simple insert/update/delete of records to a table.
The schema simply has 2 tables - master and detail where the detail pk is made up of the master id and a start date:
CREATE TABLE master (
id NUMBER NOT NULL,
name VARCHAR2 (10) NOT NULL,
CONSTRAINT pk_master
PRIMARY KEY ( id ));
CREATE TABLE detail (
id NUMBER NOT NULL,
start_date DATE NOT NULL,
name VARCHAR2 (10) NOT NULL,
description VARCHAR2 (100),
CONSTRAINT pk_detail
PRIMARY KEY ( id, start_date ));
ALTER TABLE detail ADD CONSTRAINT d_m_fk FOREIGN KEY (id) REFERENCES master(id)
This works fine when I create it in a similar manner to that described in the "Complete ADF UIX Application ..." tutorial doc.
http://www.oracle.com/technology/products/jdev/collateral/tutorials/9050/adfuix_tut.html
I then tried to override the ADF doSelect and doDML methods as outlined in ADF_BC_StoredProcedures.zip example app allowing me to use PL/SQL stored pkg for dml.
http://www.oracle.com/technology/sample_code/products/jdev/10g/ADF_BC_StoredProcedures.zip
On trying to insert a new row my web app now fails with a null pointer exception when I press the Submit button. The app calls doSelect->handleStoredProcSelect which fails to get the value of a column.
void handleStoredProcSelect() {
CallableStatement st = null;
try {
String stmt = "BEGIN test_api.do_select(?,?,?,?,?); END;";
DBTransaction tr = getDBTransaction();
st = tr.createCallableStatement(stmt,1);
## This line works, I'm guessing because the value is populated from the master record I've selected in the form ...
st.setLong(1,getTestId().longValue());
##FAILS HERE st.setDate(2,getStartDate().dateValue());
Update,delete still work ok. And if I run the test app (right click on AppModule and select Test) all works ok.
I'm not sure why doSelect is called on an insert so I commented out:
doSelect
handleStoredProcSelect
handleStoredProcLock
compareOldAttrTo
Web App now lets me insert as expected.
So finally ....my question is:
Whilst the app now works does commenting out the doSelect leave me open to problems I haven't thought off
and if not if you did want to use it how can you allow inserts?
Any thoughts or similar experiences appreciated ...
Cheers

ADF UIX cancel/rollback button?

Hi
We're having a fair amount of trouble implementing a "cancel" button in our ADF UIX application (JDev 10.1.2). Apologies to those who read this same post on the ODTUG mailing list..... I'm hunting for even a hint of an answer before I approach Oracle Support.
To set the scene, we have a parent VO "Departments" with child VOs "Dispatch" and "Agency". Dispatch also has a FK to Agency.
We have a UIX view-screen that displays in a master-detail relationship Departments and Dispatch. From this screen the user can select the edit button, which navigates to an input-form screen to edit the currently selected Dispatch record.
The Dispatch record has effective_from and effective_to dates. The underlying EO has a MethodValidator that ensures the from date <= the to date.
On the edit screen we currently provide 2 buttons, Ok and Cancel. The Ok submitButton is bound to the commit binding, and navigates back to the view page via a struts link on completion.
If the user selects the ok button and MethodValidator returns an error, the edit page's MessageBox displays the error and the user remains at the edit page until they resolve the issue.
Our problems start with the cancel button.
Originally we implemented the Cancel button as a simply "button" that navigated back to the view page. This worked well as the changes are never submitted, and on returning to the view page the record is presented in it's original state before being edited, thus the user's changes have been "cancelled".
However if the user was editing an existing record, entered invalid dates that violated the MethodValidator, clicked ok and saw the MethodValidator error, then clicked cancel, on returning to the view page, any changes to the underlying record are visible including the invalid dates. I believe this occurs because the record has been submitted to the mid-tier by the ok button, and as such the changes now lies in the mid-tier.
Given that a cancel "button" which simply navigates back to the view page is not a viable solution, we decided to investigate using a rollback button on our edit page, which then navigated back to the view page.
There is a nasty side affect in using the rollback functionality, and has been a continuous frustration mentioned on OTN. When rollback is issued, it appears all iterators in the running application have their current row reset to the first element.
This is a pain as in our example this results in not only the Dispatch iterator being reset to the first element, but also the parent Departments iterator, and presumably all other iterators in the application too. This would be an extreme annoyance to the user in every time they selected cancel, they would then need to navigate back to the correct Departments and Dispatch record if they wanted to make a different change.
As such it is necessary to write some code to store the iterator positions before issuing the rollback, rolling-back, then restoring the iterator positions from the saved states.
Luckily we found some code on OTN to do this:
ADF - cancel button not working in input form(add new row)?
This mechanism appeared to work, but, then, we did find one problem.
I described at the beginning that our Dispatch VO is not only related to Departments but also Agency. To cater for this in our edit screen by including a LOV bound <messageList>, which displayed the relating Agencies for the user to select from.
In using the pinched OTN rollback code, in the same scenario as previously, when the user edits a record, invalidates the MethodValidator after clicking ok, then clicks cancel, on returning to the view page, the field in Dispatch that represents the Agency is incorrectly showing a numeric result such as 0, 1, 2 etc. We realised that the value being shown is the previous edit screen's <messageList> internal index number representing the value selected in the list, and not the actual value itself.
We're note sure why the OTN rollback code is causing this to occur. Though it restores the Agency iterator's position, it shouldn't result in the <messageList> index being written to the underlying Dispatch agency field, but rather the value the <messageList> index represents.
It appears to me we're caught between a "rock and a hard-place" here. The simple solution of using a cancel "button" doesn't work when errors are raised. The complex case of using a "rollback" button doesn't work due to the problem with the <messageLists>.
My research on OTN shows the "cancel vs rollback" button is a common frustration. Can somebody help me in providing a satisfactory "cancel" button that I can use throughout my app please?
Many thanks in advance.

Binding Editors not present in ADF UIX

Hi
I have been having some trouble with accessing both the Boolean Binding Editor and the LOV Editor from the structure window, when in design mode of an ADF UIX page.
My bindings are present, but when I 'Edit' the binding, the only option available to me is to select the Iterator and the attribute.

the primaryclient action should pass the rowkey of the current row (${uix.current.rowKeyStr}) as a parameter. This way the server can find the corresponding row on the server in an event handler.

ADF UIX programatic data binding

Oracle ADF UIX Developer's Guide mentions the possibility to use the UIX framework in Java, to create new objects or alter the existing ones.
E.g. we can create a table using a construct like:
TableLayoutBean tlb = new TableLayoutBean();
The same document demonstrates the data binding:
BoundValue rows = new DataBoundValue(_YOUR_NAMESPACE, YOURNAME, "rows");
tlb.setIndexedNodeList(new DataObjectListNodeList(rows));
For "simple" attributes using DataObject DataObjectList, etc. the procedure is clear. But what about creating a data bound table or input text:
<table model="${bindings.EmpView1}" ... >
<messageTextInput model="${bindings.DeptCode}"/>
Itâs easy to understand that model="${bindings.EmpView1}" or model="${bindings.DeptCode}" are equivalent to multiple attribute bindings (data, validation, read-only, etc.), but it looks that the classes/methods resolving these equivalences and linking the bean to the corresponding DCControlBinding, are not public (or maybe I was not able to find them).
How can we obtain programmatically, in Java, the same structure as described above (in XML)? The best would be to use the same classes used when the UIX XML document is parsed to create the page description.
It would be very nice to be able to use a structure like
tbl.setModel( new JUCtrlRangeBinding(...) );
txt.setModel( new JUCtrlValueBinding(...) );
or maybe
txt.setAttribute( "model", new TextInputModelBoundValue(...) ) etc.
In JSF we can do something like:
ValueBinding vb = application.createValueBinding(value);
component.setValueBinding(attributeName, vb);
Can we do something similar in UIX?
Any help will be appreciated,
thanks,
Mircea Ionita

Since the code is already written, it's a pity that we can't use/extend it. I don't like to say it (sorry) but I find this design choice (implement the "model" only into the XML parsing layer) a little bit strange (or maybe I don't understand... ;-) ). We should (or we are supposed to) be able to do in java everything that we can do in XML.
I would like to find more support/help for the programmatic approach. I have the feeling that you are too focalised on "use-our-state-of-the-art-tools/wizards-to-write-the-code-for-you" and you forgot that this is not suitable for all projects. E.g. our application creates the user interface according to a layout defined by each user. To generate it, we need to use at maximum the extension mechanism and we can't simply relay on "rendered" attribute etc.
-When should we expect this new UIX release?
-What about the UIX controller? The Struts controller will replace it?
-What about the source code of uixexp2-demo.jar (distributed with ADF_UIX_component_guide)?
-Why while debugging we can't set a method/class breakpoint on UIX classes (to understand the data flow) - the stack is secret?
Thanks

LOV /ADF UIX pages does not work on the older version od UIX page

Hi
I have recently migrated UIX project from the Jdeveoper 9i to Jdev10g version 1.0.1.2, everything work without any issue, however when I try to create a LOV or any component that are ADF-UIX based, but it does not work I don't even get any error, it just does not work based on the ADF-UIX (Expression base component),
Any help to resolve this issue will be greatly appericated
Thanks

I too have problems with LOVs in UIX pages. I have
some that you have to run twice to get back a value.To solve this problem,
1) open your UIX page where you create a new row
2) in the Structure window, click third tab "UI Model"
3) double-click the control action binding corresponding to Create
4) select CreateInsert from the list
The problem is related to the fix we introduced for the "Blank Row Issue" (see http://www.oracle.com/technology/products/jdev/tips/muench/blankrow/index.html).
If you have access to MetaLink, please refer to Note 299860.1 and Bug 4201020.

Data Binding in ADF UIX example trouble

Two related questions:
From the help example 3. Data Binding in ADF UIX example trouble in JDeveloper on UIX. If this worked I was going to run a small java class that captures the login and passes it as a messagebox with a Welcome login name on the first page, but I can't get past the example and path problems.
From the example..."
package yourpackage;
import java.util.Date;
public class CurrentDateBean
public CurrentDateBean() { }
public String getTime()
return (new Date()).toString();
Now, we want to change the page so it uses getTime(). We need to do three things: Tell UIX to data bind the text attribute. Add a <dataScope> to the page to provide data to the content. Write a small "data provider" in Java that can access the bean. First, we'll data bind "text": <text xmlns="http://xmlns.oracle.com/uix/ui"
text="${uix.data.currentDate.time}"/>The example has one small change. The value is changed to ${uix.data.currentDate.time}, which is an expression that defines the data. This is shorthand for "get the time property from currentDate." If you tried running this example, you'd see nothing. That iss because we haven't given currentDate to the page, so the databinding failed, and the "text" is left to null. We do this by adding <dataScope> to the page: <dataScope xmlns="http://xmlns.oracle.com/uix/ui">
<provider>
Q#1?? Trying to follow the demo. The method class and method name do not seem to match the names in the above class from the demo. Am I missing a point here, please help.
<data name="currentDate">
<method class="yourpackage.DataDemo" method="getCurrentDate"/>
</data>
</provider>
<contents>
<text text="${uix.data.currentDate.time}"/>
</contents>
</dataScope>
Q#2?? When I try and apply the demo class to my home.uix XML file with
"<?xml version = '1.0' encoding = 'windows-1252'?>
<page xmlns="http://xmlns.oracle.com/uix/controller"
xmlns:ui="http://xmlns.oracle.com/uix/ui"
xmlns:data="http://xmlns.oracle.com/uix/ui"
xmlns:ctrl="http://xmlns.oracle.com/uix/controller"
xmlns:html="http://www.w3.org/TR/REC-html40" expressionLanguage="el">
<content>
<dataScope xmlns="http://xmlns.oracle.com/uix/ui">
<provider>

<data name="currentDate">
<method class="us.mn.state.dot.apptrack.security.CurrentDateBean" method="getTime()"/>
</data>

</provider>
<contents>
<text text="${uix.data.currentDate.time}"/>
<document>
<metaContainer>"
I get the following, and I don't know how to make the UIX XML accept the correct path, please help:
�file:/C:/JDeveloper905p/jdev/mywork/ProjTrack/AppTrack/ViewController/public_html/home.uix: Parsing error, line 12, column 97: Could not find class us.mn.state.dot.apptrack.security.CurrentDateBean

for question 1 the name of the class CurrentDateBean
actually has nothing to do with the el expression
uix.data.currentDate.time. The currentDate part of the
el expression is coming from the method data provider part
of your page:
<data name="currentDate">
<method class="yourpackage.DataDemo"
method="getCurrentDate"/>
</data>
so if you changed the name of the data provider to "foo":
<data name="foo">
<method class="yourpackage.DataDemo"
method="getCurrentDate"/>
</data>
your el would look like this:
uix.data.foo.time
by the way the uix.data part tells UIX to look for
a <data> element define in the <provider> section of
your dataScope.
For question #2, do you have the java file
us.mn.state.dot.apptrack.security.CurrentDateBean on
your classpath and is it compiled? You will get that
warning if it is not on your classpath.
Also you are incorrectly interpreting the example. What
you are doing is trying to reference the actual bean
object and its getTime() method. What you want to do
is write a method data provider that returns your
CurrentDataBean. so uix.data.currentDate would return
a CurrentDateBean instance object. the .time part of the
el expression would tell UIX to look for a method named
getTime() and use that value.
let me know if you have any more questions.

Reset of current row after commit in ADF-UIX

Dear experts,
I have developed an application with Oracle JDeveloper 10g and ADF-UIX using BC4J. The problem is that wherenever a commit is performed the current row for the master table is reset which causes confusion for the end user.
Do you know how can I solve that problem?
Thank you in advance,
Constantine

... I forgot to mention that I use JDeveloper 3.1 on Windows NT4.
About my problem, it seems that a "key" does not exist in the record (Row object) i'm using for.
So, what really is a "key"? Is this an internal complicated number or just the values of some data fields, indicated as "Primary Key" in the table?
If the answer is the second one, I have to say that at the really before commit of the record, the value of my primary key fields is NULL, because they are filled up by a "sequence object" created in the database (triggered by a "TRIGGER BEFORE INSERT", which calls the "sequence.nextval" SQL command).
So, I really have the value of my primary key fields just after committing the record in the database, and would explain everything.
But is really this the "key"?
Thanks

Display requestScope attributes within ADF UIX page

In jsp I can do the following to display all attributes available in the current requestScope by
      < c:forEach var='parameter' items='${requestScope}'>
         < ul>
            < li>< b>< c:out value='${parameter.key} : ${parameter.value}'/></b>:</li>
         < /ul>
      < /c:forEach>How to do the same in ADF UIX (without using servletInclude)?

Please provide an example
This works
<styledText text="parameterMap ${uix.bajaContext.servletRequest.parameterMap}"/>But this does not work.
<stackLayout>
<contents childData="${uix.bajaContext.servletRequest.parameterMap}">
         <styledText text="text: ${uix.current.key}"/>
   </contents>
</stackLayout>How to use ${uix.bajaContext.servletRequest.attributeNames} for instance since this returns a java.util.Enumeration type?
