ADF Faces inputFile/progressIndicator question

I'm using JDeveloper 10.1.3.1.0 on WinXP SP2, JDK 1.5.
I'm trying to use af:inputFile with an af:progressIndicator to track the progress of uploading and processing the file.
While the basic setup I have works, it's ugly and intrusive to the user. The progressIndicator and the af:poll's polling are active as soon as the page is displayed.
What I want to do is to hide the progressIndicator widget and delay polling until the user presses the "Update File" button. I've tried all sorts of combinations of setting "rendered" to "false" in the .jspx file and then resetting it to "true" in response to various events in the managed bean, but have had no luck with any of these attempts.
I'm out of ideas. Has anyone tried this and succeeded? It seems like a common thing to want to do, yet completely non-obvious (at least to me) as to how to do it.
Thanks in advance,
Rick

ADF Faces - Using ProgressIndicator Component as a Process Indicator

Hi, I'm working on JDeveloper 10.1.3.2.0 and I'd like to know if there is an example anywhere for the next case:
I have 2 jspx pages: one is a form with search fields. The other one is a table with the results of the search.
I made some tests with both Poll and ProgressIndicator so that, when the user clicks the "Search Button", the clock of the ProgressIndicator component appears (just the clock) and, when the search is over, the application redirects you to the results page.
I had to use javascript and I almost got it, but there's a problem. Once you're in the results page, if you click the "Back" button of the browser, the clock appears as if you're requesting the search again (but you're not, of course)
Do you know if there is a simpler way to achieve this solving this last problem and without javascript code?
Thanks in advance

Hi,
you can use the JavaScript on the target page in an onLoad statement to delete the browser history. This way the back button doesn't work at all. I received a mail from another customer who did it that way

Customizing ADF Faces Look & Feel. Some questions & suggestions

Hi everybody,
We are developing an application with ADF Faces using JHeadStart. For the moment, I am studying the way we must modify the JHS templates to adapt each element to our needs.
As it's told in the JHeadStart Developer's Guide, there are two ways to customize Look & Feel:
1) Modifying the templates
2) ADF Skinning
I'm using both methods, but I feel that thay are not good enough to adapt the L&F to our customer requirements.
My main problem now is in the ADF Table customization. I want to use ADF Table because it offers us a lot of features that are not in the jsf table (the selection column, the table overflow...), and is very usefull combined with the generated JHS code. But at the same time, it doesn't offer a lot of functionality in the look & feel customization. Using JSF Table, I can set the CSS style for headers, rows, columns, the table, I can set the border, cellspacing and cellpadding. But I cannot do
any of these thing (or at least, I don't see how) with the ADF Table.
Our customer (a government) have a strict definition of the look & feel of his web applications. They want we use their CSS styles definition file, so they can modify at once the Look & Feel of all their applications. Modifying the L&F through skinning generate other styles, not use the style classes in our CSS (o so I think).
So, the questions:
1) There is any way to set the suitable styles for the ADF Table components (headers, rows)?
1bis) Why, If I have defined a new skin, with only just a few selectors, some styles from oracle are applied? Maybe because the render kit in the 'adf-skins.xml' is "oracle.adf.desktop"? If it is true, how can I make that they are not used, I must implement a render kit or can I use another existent?
2) Can I decide how looks the select column (for example a button instead of a radio button)? Can I decide where does it goes (right or left)?
3) There is any way to hidden the text Show/Hide of the showDetail in the table (the tableOverflow), as I can change the icons through skinning? If it is not possible, How can I overwrite the text. I need it in Catalan, but it is shown in English for this locale. Where is the message bundle I should overwrite?
4) There is any way to force a tree to start fully expanded?
5) There is anywhere documentation about the javascript functions used in ADF and their meaning? I think for example in the previous question. If I knew which javascript function I should call for expand the tree and its parameters, I could put the call in the onload event of the body.
6) I use a selectInputDate. I have skinned the launch-icon, and I would like to do a similar thing in the chooseDate that is opened in a new window. But It seems not to be affected for my skinning directives (if I put a chooseDate in the same page, its L&F follow the skinning rules I've defined). I don't know if this dialog is an ADF feature or a JHS generated feature.
7) There is any way to keep unmodified the id I've choosed for a component? (I mean, an inputText with id="hello" in a form with id="form" will have in the HTML an id = "form:hello", but I would like it to be simply 'hello')
8) How can I control the position and the size of a dialog (the chooseDate dialog or a dialog I've created)? In the cases I've been testing, it seems the dialog is forced to resize depending on the content. I would like to know if I can establish a fixed size.
9) There is any way to open a non-modal dialog? (which I could keep open at the same time that another instance of the same dialog)
For the moment, I think I have no more question. But give me time.... :-D
The suggestion I've to do is basically more flexible components for a better customization (for example, the styles settings I've talked about previously). ADF components are nice and powerful, but I think they should generate pages that follow the tendencies in the web development: tableless pages (I cannot understand the utility of the objectSpacer existing the margins), use of CSS for layout...
Any answer, comment or suggestion will be welcome.
Carles.

I have been able to make the UIX 2.2 and ADF Faces LAF look near identical by updating the oracle-desktop.xss file within UIX 2.2 as follows

<style name="DarkAccentBackground">

<property name="background-color">#d2d8b0</property>
</style>
There are still some differences:
1) A black line appears on the ADF Faces on the 'menu1' facet selected tab below the text. DON'T KNOW HOW TO REMOVE THIS FROM ADF Faces or add it to UIX 2.2!!!
2) In UIX 2.2 a bulleted list uses the HTML <li> tag. In ADF Faces it doesn't use the HTML <li> tag rather it constructs the bulleted list using lower level HTML tags with the 'bullet' becoming an image, in my browser this means the disc is smaller in Faces. The motivation for this change I think is explained via this post. Since I have no control over how this specific HTML tag is rendered it forces me to replace the /adf/images/bltdscn.gif file in adf-faces-impl.jar with a larger disc!

May update this again if there are other things I notice.

ADF Faces: Table detailstamp facet question

Questions for ADF Faces

I have been following this forum for about a year now and thought I should raise some questions regarding current ADF Faces state.
With the recent donation to Apache, is Oracle going to continue roll out enhancements and is there going to be an ADF.Next?
A good place to demonstrate commitment is by having a dedicated ADF Faces and BC forum (preferable built using it too!).
There are several third party vendors that offer key JSF based UI components (AJAX based table, input, menus, drag and drop, etc.. ), are there any plans to incorporate these into the ADF Faces component library?
Finally, has anyone deployed ADF based application in production? If you have a success story you would like to share, I have a case of beer with your name on it. Shoot me a hello at [email protected] See you at OOW.
-Wes

Oracle is still developing ADF Faces - but now we are doing it together with Apache on the trinidad project.
In addition Oracle is building an AJAX based rendering kit on top of the components - you can see a demo of these new components if you'll check the replay of Thomas's Kurian keynote at this year's Javaone.
http://webcast-west.sun.com/ramgen/archives/06D00627/06D00627_03_300.rm
If you want an ADF Faces forum - you can use the apache forum.
We rather keep a unified forum for all things related to JDeveloper and ADF, since there are many questions that cross the boundries between topics, and since it makes it easier for us to only need to monitor a single forum.
And yes there are ADF Faces based applications out there in production, and some of them are even on the Internet.

ADF BC and ADF Faces deployment question

Hi all,
In my previous web project, the middle layer was packaged into a .ear file and deployed onto a sever that had jboss running. My client layer was deployed on a seperate server running tomcat. My question is how do I accomplish this seperation with BC and ADF Faces in terms of deployment?
Thanks.
Z

Let me be a bit more specific.
Here is the tree view of my application workspace:
-My Application
  -Model
    -Application Sources
      -org
      -org.myorg
      -org.myorg.model
      -org.myorg.model.entity
      -org.myorg.model.association
  -View
    -Application Sources
    -Web Content
Can I deploy only the model or middle layer on server A running oc4j and deploy the view layer on server B also running oc4j?
Thanks.

ADF Faces Core Table, TableSelectOne question

Greetings
I am using ADF Faces Core Table to display a list and I have it setup with TableSelectOne, it works great. My question is this, I set required = true on the select button and it works. If I dont select one it no longer submits. My question is how do i get the error message back out I tried adding an af:message tag with from = tableSelectOne1 and I dont get anything back out. Is there a way to get this error message out so I can display it for the end user?
Thanks
tro

Hi,
Try using af:messages instead, as it displays all messages added to the FacesContext.

ADF Faces & BC, JDeveloper 10.1.3.4: Editable af:table question

Hi all,
I have a dialog which pops up with an af:table inside, the table is bound to a viewobject which is used to create multiple rows which upon clicking a save button, these records will go into the db. My problem is that lets say I have 3 rows that are created (via programmatic CreateInsert on the AM), when I use the UI to modify a attribute value on the first row, the same value is copied to the rest of the 2 rows.
See image of UI below:
[http://i108.photobucket.com/albums/n23/zeoneozero/beforesave.gif]
I do not wish to use a radio button next to the rows as I want the user to freely edit which ever field directly without clicking around too much. Should I be setting the autosubmit to true and a valuechange listener to set the current row?
Many thanks,
Wes

A Question about ADF Faces, File Uploading in distributed environment

Hello,
I am using ADF Faces for my project. In my project members will be able to create their albums and upload their photos..
The problem is that i can do upload in a single server enviroment but i dont know what will happen when count of members will grow.. What is the best way
for managing these photos in clustered enviroment. 1 Server will not be enough if too many people upload their photos.
I do not have exact server number because i will add additional server nodes when it will be necessary, so i must think how to do that before production.
Do you advice me to use XML or keep addresses of photos in database? Or anything else? As i mentioned, i dont know how many servers i will have... maybe 1 maybe 5 maybe 10.
Thanks for your helps..

Hi,
First of all, thanks for your replies..
Actually i do not want to keep all of videos and photos in database. Keeping them in directories will be better for me but i do not know how to share them between multiple server nodes..
This is the thing that i have never done before..
Can you please tell me the terms & keywords that i need look for? So i can find some documents about making this happen.
Thanks again..

Developing a User Interface with ADF Faces - Tutorial - Questions

Hello everybody,
I am a forms developer and I am totally new to ADF.
I started from the tutorials : Developing Business Services with ADF BC and Developing a User Interface with ADF Faces...
Everything was easy and very clear, as far as the material covered in the tutorial is concerened.
But when I tried to modify a little bit the application, to perform a different task... disaster!!! :-)
One of the "simple" things that I tried to do -for example- is :
In the login.jspx, where we have created an ADF Parameter form (that accepts as a parameter the customer ID) and
retrieves in the next page the Orders of the specific customer.... to Display a message, such as "+Customer Does Not Exist+"
if the user types in the parameter form an not existent customer ID...
I understand that I should use a validator.... But I cannot find the list validator (from query) in the bind variables not in the ADF Parameter Form Fields....
Does anyone know?
Regards,
Maira Kotsovoulou

Dear Grant,
CustomerID is in the UI Project, and appears as a part of an ADF Parameter Form... and I can not find key exists in the UI Validators....
CustomerID in the .entities is a bind variable in a query. select ... from customers where customer_id = :p_customer_id. Again KEYEXISTS validator is not available in the bind variables sections... Only in the attributes!!!
I understand that the "normal" behavior in a query with bind variables where there is no match is to display nothing as it does!!!
But I was just wondering, if I could even trap that before I display the empty form...? Or could I display a text in my ADF form, that says no rows... (as I can do in an ADF Table???)

ADF Faces: state saving method questions

Please, could somebody elaborate implementation of state saving in ADF Faces? What specially interests me is a way on which it is improved in comparison with RI. Will be current implementation further improved regarding size of state which is stored in session or on client?
Further, is it possible to make a read only page stateless? I tried naively to implement restore view phase listener which sets up transient property of view root to true. Page was rendered fine, but when I try to post something from that page NullPointerException was thrown from UIXComponentBase._getRendererImpl() method.
Tnx

Could you elaborate on the back button support?
I'm trying to do something very simple right now with two JSF pages using ADF BC/Faces. One page is a simple table allowing the user to select a row. The second page allows the user to view details on the selected row. This is view only at this point. I've found however, that if I select a row and go to the detail page and then hit the back button to return to the first page and then select another row and attempt to go to the detail page I get an error message like so:
1. validation - JBO-29000: Unexpected exception caught: oracle.jbo.JboException, msg=JBO-35007: Row currency has changed since the user interface was rendered. The expected row key was oracle.jbo.Key[1246992000 ]
2. validation - JBO-35007: Row currency has changed since the user interface was rendered. The expected row key was oracle.jbo.Key[1246992000 ]
I'm at a loss as to how to resolve this issue.
Thanks,
Corey

ADF Faces : UploadedFile missing bytes

Thanks for your reply John.
In the Re: ADF Faces file upload: losing bytes on PDF file you refer to, you write "I'm currently guessing something wrong in the DB with Intermedia, but not sure.".
But, using the ADFUploadedFileIssue-v0.01.zip example application I posted in this forum thread, it is clear that something is already wrong in the UploadedFile implementation.
Currently I only have bug 6774514 logged, but no solution yet.

ADF Faces - Which type of barcode scanner is recommended for ADF JSP?

Hello everybody:
1.- I'm trying to implement and adf faces app, with the functionality to get some
data from a barcode reader.
2.- I was reading about the different types of reader's interfaces: keyboard wedge,
RS232, USB, bluetooth, etc.
--- QUESTION' SECTION ---
3.- First, the best thing is that my app could be compatible with all interfaces, I
don't know if this is possible without any changes to the code.
4.- If the previous point is not possible, I know that at least my app has to be
compatible with the KB wedge and RS232, because I have read that the USB
just emulate these two interfaces, but in an USB port.
5.- I haven't read to much about this, but I need that my app do a post imediately
after read the barcode, so the best thing my mind could imagine is add an
<enter> char from the reader, I read too that this is only possible with the
RS232, is the only way to modify the output of the scanner before send it to
the app, and with the KB wedge is not possible.
6.- But, the KB wedge is easier to use because my app does not require any extra-
code to handle it, the only thing is: the cursor must be in the correct place in
the correct time.
I have read in this forum that some people has already implement this, if some of
you guys have any suggestion, please let me know.
Thnks in advance.
Alex.

Hi,
thre is no specific certification between barcode readers and ADF Faces. So if you need a barcode reader, it s up to you testing which one can interact with the browser to fill in the form fields (and this basically is all it does)

EJB 3.0 / Data control binding / ADF Faces

We have a great and very useful tool to generate rich client web application. Generate web component from a data structure is easy but manage the full life cycle is a little bit more complex. This complexity is dramatically increased when tool/platform are offering many models to solve the problem.
In JDev we have three major choices:
1) adf business components
2) top link pojo
3) ejb3.0
From the client side and in my point of view (at my current understanding) the first and second choice are the easiest way to manage the persistence because they are what i say "bidirectional", that mean i will use the same data structure to persist and synchronize the database. I may only calll a method from the object to put my changes from the midle-tier into the database.
EJB 3.0 seem to be more cormplex due essentially to the presence of the session bean that acts like conversational api. I like this architecture because it is the most flexible but from my client i have to manage these api's instead of one data structure. This mean for me to catch/detect every updates, new insert or deletes in my business object and to write the corresponding code to apply to correct entity bean methods from my session bean.
Why not manage this logic in the data control framework by declaring which methods are to use as finder to get the data and which methods are to used to manage the persistence (persist, merge, remove) at object level.

Exactly what i mean
Actually Data Control architecture seem to be business object oriented with native method called from the same object to retrieve (the most part done)/synchronize the data with the database.
This is fine than your architectue don't provide a service layer like session facade.
With session facade you will access different business method to retrieve data and synchronize you data with the database not different method from the same object like application module do in adf bc.
I see two solution, the best is that you extend the data control framework to offer standard crud operation and a tools to map these with one or many methods in the same (has to be the same?this is a question of architecture, i think it has to be the same but the framework may have to permit to use an another one for flexibility) session bean. This may be the same from adf bc or top link but the method may be selected automatically by the tool (wizard).
The second solution is to build specialized sesssion bean with mandatory standardized methods and map this directly in the framework. The advantage i see is that the updates may be collected only once by the session bean by passing a specialized object manipulated by a specialized method.
In fact the best solution is something that combines mapping in the data control and a specialized set of methods in the session bean to execute a transaction in a whole at the server level.
What is to be decided if the framework (data control part) has to maintain a status for attribute (or set of attribute that correspond to a data control node) that are new inserted, updated or deleted and to synchronize only the changes.
I'm very surprising that something like that it is not already in the framework ?
How do I have to take care of changes made in a data control node object when i have used it to generate an adf faces by example in master / detail pages with an edit form like in otn examples. I see that the detail list in the detail table is updated so the data control is updated correctly by the edit form when i submit the changes but how to finally get this changes and synchronize with the database ?
ps i reply previously by mistake by email sorry ... not that the email is not exactly the same as the post here

JDeveloper 11.1.2.3, ADF Faces: declarative component does not support af:clientListener?

I am trying to create a declarative component with the following code:
<?xml version='1.0' encoding='UTF-8'?>

            <af:serverListener type="TableDoubleClickEvent"
                               method="#{EditAddDialogTemplateBean.handleTableDoubleClick}"/>
    </af:xmlContent>
</af:componentDef>
At runtime I recieve the following error:
javax.faces.view.facelets.FaceletException: ADF_FACES-60023:Component: DoubleClickTableDialogClientServerListenerComponent[oracle.adf.view.rich.component.fragment.UIXInclude$ContextualFacesBeanWrapper@7170a7, id=dctdcsl1] does not support client listeners.
at oracle.adfinternal.view.faces.facelets.rich.BaseClientListenerHandler.apply(BaseClientListenerHandler.java:53)
This component was intended to be dropped off within an af:table component. I would like to hear suggestions on workarounds, one other way I thought about was to create a code template for the three tags, however, the con to this approach is each developer would need to configure this template within jdeveloper. Ideas are appreciated.
Also a side question, how can I embed code properly with the new forum? [code] tag does not seem to work now.

Wes, can't help with the real question, but can tell you how to format code
Change to the advanced editor (top right over the editor field), then you get more options. The one you are looking for is behind the blue '>>'. Here you select the language you want to insert and you get nice code formatting and color.
