ADF/UIX

We are follow this note:
http://otn.oracle.com/products/jdev/collateral/papers/10g/ADFBindingPrimer/index.html
who they are the correct steps/context to set view to "forwardOnly", due to
when I set vo.setForwardOnly(true) an exception is rise (operation not permitted).
If the view is not set forwardOnly (default) when we navigate through JSPs the framework continue revisiting the view and then calling get methods from object RowImp, is this correct?
Tx,
Diego.

Tx Steven!
I try to clarify!
I have an AppModule over DEPT/EMP table and a UIX page for this Views.
Why when run the UIX page base on DEPT or navigate to other page p.e.: emp.uix the method (p.e.)
"public Number getDeptno()" in "public class DeptViewRowImpl" is executed many an many times?
I think that they are too much accesses to DB...
Is this configurable or is a default behavior
Thakns your very much for your help.

Demo: From ADF UIX to JSF

Hello,

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?

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 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
Ian

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?

This thread is a duplicate. Direct all followups to:
Urgent! ADF UIX:LOV messageList returned index no. during runtime.

File upload, download using ADF UIX and not JSP

I have examples for the file upload, download using JSP
But I want to use ADF UIX. Look and feel in this is impressing and I want to use this. Any one have example for this.
Users will select a file from their desktop
This will be stored into the database (Any document. Word, Excel)
When they query the records then the UIX column need to give a hyperlink. Clicking on the link should prompt to download the file to the local system

Sure, I use the Apache Commons File Upload package, so that is what I will discuss here ( [Commons File Upload|http://commons.apache.org/fileupload/] ).
The Commons File Upload uses instances of ProgressListener to receive upload progress status. So first create a simple class that implements ProgressListener:
public class ProgressListenerImpl implements ProgressListener {
    private int percent = 0;
    public int getPercentComplete() {
        return percent;
    public void update(long pBytesRead, long pContentLength, int pItems) {
        if (pContentLength > -1) { //content length is known;
            percent = (new Long((pBytesRead / pContentLength) * 100)).intValue();
}So in your Servlet that handles file upload you will need to create an instance of this ProgressListenerImpl, register it as a listener and store it in the session:
ServletFileUpload upload = new ServletFileUpload();
ProgressListenerImpl listener = new ProgressListenerImpl();
upload.setProgressListener(listener);
request.getSession().setAttribute("ProgressListener", listener);
...Now create another servlet that will retrieve the ProgressListenerImpl, get the percent complete and write it back (how you actually write it back is up to you, could be text, an XML file, a JSON object, up to you):
ProgressListenerImpl listener = (ProgressListenerImpl) request.getSession().getAttribute("ProgressListener");
response.getWriter().println("" + listener.getPercentComplete());
...Then your XMLHttpRequest object will call this second servlet and read the string returned as the percent complete.

Populate Primary Key with DBSequence in ADF UIX page

I have a table with a trigger, so that the primary key is populated by DBSequence. My problem is, I open a ADF UIX Input Page to create a row for my table. The field of the primary key is populated by any number but not with the logical sequence number. This number appears later, when I look at a row list. So the correct number is in the database but how can this already appear on my input page???

You have to drop the trigger.
Then make sure you have the Id field of your entity of type Sequence.
Then go to your entity class and override the Create method.
protected void create(AttributeList attributeList)
    super.create(attributeList);
    SequenceImpl s = new SequenceImpl("YOUR_DB_SEQUENCE_NAME", getDBTransaction());
    Number sVal = s.getSequenceNumber();
    setId(new DBSequence(sVal));

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.

ADF UIX Search Form - Is this a bug?

I created a JDev 9.0.5.2 ADF UIX Search form from the component palette. I ran the page without making any changes. I chose the Find button which displayed the search criteria. I selected the delete button and then the create button, which created 2 blank records (possible bug?) in the search criteria table at the top. I selected one of the blank records and entered search criteria. I chose the submit button which changed the data in the search criteria table as it is supposed to do. I selected the other blank record, entered search criteria and submitted it. Again the data in the search criteria table was changed appropriately. I selected the delete button and the wrong record was deleted (bug?).
Are these bugs?

Hello,
a similar sort of situation is created if you have a Read-only table on a page which drills down to an edit/create input form page. If you enable a create functionality you need to enable some way for the user to back out of the created record and clean up the newly created row. On the detail page (JobsEdit.do) i created a link to a custom event on the master page action (JobsView.do) like this:
<button text="Cancel" destination="JobsView.do?event=cancelinput"/> In the Data Action class for the JobsView page i have a method defined as follows:
public void onCancelinput(DataActionContext ctx)
Row row = ctx.getBindingContainer().getApplicationModule().findViewObject("JobsView1").getCurrentRow();
row.refresh(row.REFRESH_REMOVE_NEW_ROWS );
}as a workaround, it sounds like you may need put some manual controls in place to tightly control any newly created rows which have/will not been used. I don't know if this will resolve the deleting wrong record problem...
regards,
Brenden

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 documentation keeps telling me to select different tabs, but there aren't any!
Anyone had this problem????

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.

Should I upgrade to STRUTS, ADF-UIX or to JSF

My applications still use the older bc4j objects and the trivial page flow manager. I have been looking at upgrading these apps to ADF-UIX and using STRUTS.
With the flurry of announcements about JSF, should I skip the planned upgrade above and go directly to JSF, if it's stable and complete enough, or wait until it is?
Thanks for any thoughts on this.
Steve

Shay,
Thanks for the quick response. Your comments on the lack of data binding cleared it up for me. I use data binding in my UIX code right now and plan to use more.
I will wait on JSF until a version is available with this feature.

Deploy an ADF-UIX project

Hi all!
I build a web application workspace, so I have a "model" project in witch I put some business components from tables. In ViewController project I use adf-uix. My problem is I can't deploy my work. How can I do this. I suppose that I should deploy first my "Model" project.
Thanks in advance.

Hi Luigi --
You'll be better posting this to the specific JDeveloper forum. The people who know all about ADF are there and will be able to help you out.

Oracle ADF UIX and Struts

Does Oracle ADF UIX use Struts components internally? If yes, Does Oracle Support the issues that arises because this internally used Struts components? (I am using Oracle ADF in my application.
Thanks,
Aravind.

DataForwardAction and DataAction are build on top of struts actions to coordinate ADF databindings and it's life cycle;
UIX, has xmlns:struts="http://xmlns.oracle.com/uix/struts" this XML namespace has some elements like
<struts:form> and <struts:messageTextInput> also <struts:dataScope>
They work like struts jsp tag;

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
