Refresh text field

hey,
I've an active output text component which should be updated as the data is changed in the database. I've already tried af:poll but it creates a problem when used in the template.
I've seen some descriptions on active data services which I think would a solution to this problem. but I couldn't find any example as to how this could be done.
So how can I use active data services to update the text field value when the changes are made in the db or can anyone guide me to an example?
thanks

Hi,
See if the following link on Active Data Services helps:

Problem with Refreshing the data bound text fields

Folks,
First of all, this a GREAT product and I am moving my apps from Eclipse to Studio Creator. I am very impessed with it so far.
I am gone through most tutorials, but can't help resolve the problem that I am having. I have a page, that lists all the users in a table. When you click on any user, it opens up another page that lists the detail of the specific user you have clicked on. This a typical use in most web applications, right?
In the user detail page, I open it in "Read" only mode, by setting the "setReadOnly" to true for all text field components. Then users can edit it by clicking "Edit" button. Edit button just changes the "setReadOnly" to false, to allow editing. After editing, they can hit the "Save" button to save the changes. In the save button, I call this code:
public void prerender() {
        try {
            userID=getSessionBean1().getUserID();
            getSessionBean1().getWeb_userRowSetUserDetail().setObject(1,userID);
            getWeb_userDataProviderUserDetail().refresh();
            info("prerender: Refresh called");
        } catch (Exception ex) {
            error("Error in userForm.prerender():"+ex.getMessage()+ex.getStackTrace());
            log("Error in userForm.prerender():", ex);
        setReadWrite();
public String btnSave_action() {
        try {
            getWeb_userDataProviderUserDetail().commitChanges();
            getWeb_userDataProviderUserDetail().refresh();
            info("Data Provider Refreshed in SAVE");
            _readOnly=true;
            form1.discardSubmittedValues("saveVForm");
            info("User Updated New:"+userID);
        } catch (Exception ex) {
            log("Error Description", ex);
        return null;
    public String btnEdit_action() {
        try {
            _readOnly=false;
            //info("User ID Edt="+getSessionBean1().getUserID());
        } catch (Exception ex) {
            error("Error in userForm.btnEdit_action:"+ex.getMessage()+ex.getStackTrace());
            log("Error in userForm.btnEdit_action():", ex);
        return null;
    private void setReadWrite(){
        // Set read-only to true or false for all text fiels
        this.btnEdit.setVisible(_readOnly);
        this.btnSave.setVisible(!_readOnly);
        this.user_id.setReadOnly(_readOnly);
        this.user_email_client.setReadOnly(_readOnly);
        this.user_email_office.setReadOnly(_readOnly);
        this.user_fname.setReadOnly(_readOnly);
        this.user_lname.setReadOnly(_readOnly);
        this.user_id.setReadOnly(_readOnly);
        this.user_password.setReadOnly(_readOnly);
        this.user_password_conf.setReadOnly(_readOnly);
        this.user_phone_cell.setReadOnly(_readOnly);
        this.user_phone_cell_aac.setReadOnly(_readOnly);
        this.user_phone_client.setReadOnly(_readOnly);
        this.user_phone_home.setReadOnly(_readOnly);
        this.user_phone_office.setReadOnly(_readOnly);
    }When the save button is clicked, the database is updated (as I can verify by looking directly into the database), but the data-bound text fields do not display the new value. YES, I am calling refresh() on data provider? I tried to call refresh in both "preRender()" and "Save" button action event, but that did not help either.
Please note that the save button also changes the "setReadOnly" back to TRUE for all text fields. That means, users view the page in Read-Only mode after saving. (They have to click on "Edit" button again to edit it). I discovered that if I do not set the text field components in "ReadOnly" mode, then they display the updated value of the fields. But if I change setReadOnly to TRUE, then they display the old values (before the save).
Any idea what I am doing wrong here?
Thanks

Here is my experience with it. I have three text
boxes to be filled out. They are part of a virtual
form with an add button as the submit. You can fill
out the 3 and add them and a node is added to a tree
component. When you click on a node in the tree
component (the submit to another virtual form that
the 3 buttons participate in) the text fields should
be loaded with the values that they where added with.Hard to tell from this explanation, but if the text fields do not participate in a virtual form, then they are not going to get updated when an action in the virtual form happens. Not sure this is your problem. Like I say, hard to tell from this explanation.
They will not display the values though...having
nothing to do with read only. If I disable them
before hand...they display the updated values. If I
set their value at the top or bottom of prerender,
they display the change...if I set the value in an if
conditional that is hit (I have checked many times)
in prerender, they will not display the values. If I
set them in the tree handler anywhere, they will not
display the values. This is very frustrating and is
wasting tons of my time...I simply want to load the
text fields based on the tree node that was
clicked...I have messed with this for hours and it
certainly does not work.Well, setting them in the tree handler won't work because the tree handler gets called in the page instance that handles the submit and not the page instance that renders the response.
Posting your prerender code might help. Also, your action handler.

Refreshing a text field in an applet

I wrote a program which produced a lot of numbers as output. I installed this program into an applet by calling it from the start() override and converting the number to a string then placing it in a text field. However, it only seems to display the last number. I am getting the impression that the display is only refreshed when the applet finishes. Is this generally the case? I have put in a call to repaint() after each output but it doesn't seem to make any difference. I know the program is working because the numbers appear in the OUTPUT window in IDE too, as I have done a System.out.print.

Here is my crazy programme. I put a sleep in but no difference. If I append to the buffer then all goes on the same line, which is not what I want. Also all appear at once when the program completes, but I want to watch this thing running. It produces prime numbers and increasing mp makes it produce lots and lots of them.

Trying to use web app text field to redirect a page.

I am trying to create a web app, that will provide 'members' with a page that they can use to redirect to other pages of their choice. What I want to do is allow the member user to select (from a dropdown menu, or even input their own into a text field) a specific url (i.e. http://www.facebook.com/myfacebookpage) on their customer page. Once they select the url they want, and save their info, that url will be used in a redirect page, (i.e. <meta HTTP-EQUIV="REFRESH" content="0; url={tag_redirectURL}"> or something to that effect. Has anyone done this or have any ideas how to do it? Ultimately, I want the user to be able to change on the fly where someone goes when they share their user link with a friend (i.e. http://www.mywebsite.com/userpage/ will take someone to a facebook page or to a youtube video, or some other page they redirect to) so they can switch it on their own when they choose to.

Hi Scott,
You could create a web app which as a text (string) field in it for customers to enter the URL they want to redirect the customers to. Then place a JavaScript redirect inside the detailed layout, which would look like this:
<script type="text/javascript">

</script>
Give them access to secure zone, place a web app item creation form onto it and you're good to go.

How to get data from list of values (LOV) to be displayed in a text field ?

Hi guys,
I am very new to Oracle APEX so please spare me if it is a silly question. How can I get the selected values from a set of list of values (LOV) displayed in a text field (or text area or so) ? Fox example, in my form I create 4 items: STATE, COUNTY, STREET, ZIPCODE and all of them are LOV (list of values). I also create 2 buttons (ADD & REMOVE). Then I create a test field (or text area name SELECTED RECORD). Now here is what I want to do with my form:
When I set the values for all 4 fields, I will click on the ADD button then I want those values be displayed in the text field.
For example, if the selected values are:
STATE = Alabama
COUNTY = Abbeville
STREET= 1 Street
ZIPCODE = 36310
And the ADD button is pressed. Then in the text field I want it displays like this:
Alabama,Abbeville,1 Street,36310
If I choose other values and click ADD again, a new line will be added into the text fields (text area). If I click the REMOVE button, then it will clear those two line in the text field.
Would it be possible to do it? Any help will be greatly appreciated. Thanks in advance.

If you can live with the page being submitted and refreshed, make your ADD button do a submit with a request value of ADD and make your REMOVE button do a submit with a request value of REMOVE.
Then create two computations (one firing with a condition of Request = ADD and the other firing with a condition of Request = REMOVE).
In the ADD one, concatenate the values together into the text area (most likely a PL/SQL computation wiill be what you want). In the REMOVE one, set it to null with a PL/SQL computation.
If you want it done without submitting the page, make the buttons each do a redirect to a URL but instead you will have to write two short javascript functions in the page HTML header to manipulate the field values. Each button would call each javascript function in an onclick event.

Safari 5.1.2 keeps changing text field randomly on text input

Hello everybody.
Safari keeps changing the text field on input, do you know how to correct this issue?
Here is an example:
Let's say I load www.google.com, it appears in the safari window as usual.
Suppose I begin to type a search in the google search field at the top right of the safari window (not the one on the google page)
if when doing this the sentence is long for the search, at some point randomly, the rest of the text will be entered this time in the google search text field on the google page! (which is the very next text field) So when I hit enter it makes google search half of my request...
Safari changed the text field I was into with no warning. I want to say I do not press tab at any moment.
This is annoying really, and this does not appear anywhere else than in Safari. It seems the issue is not systematic, but appears quite often.
I have no universal access setting except "enable access for assistive device"
I had to check this box upon installing a software in the past but I can't remember what it was.
Perhaps the problem I have is linked to some window refreshing?
Thank you for your suggestions or help
Mac Pro, 10.6.8

Try deleting the cache associated with Safari ...
Quit Safari.
Go to ~/Library/Caches/com.apple.Safari/Cache.db.
Move the Cache.db file to the Trash.
Relaunch Safari to test.

Update a text field based on a SelectOneChoice field

Hi,
I have a set of Create, Confirm and Thankyou screens. These screens are bound to a global view object. The create screen has a SelectOneChoice element which allows the user to pick an employee. When the selection is made, I need to display the employee's department in a read only text field below the dropdown. The Employees list(SelectOneChoice) is associated to the read only view object and this view object also has the employee's department information. Im dont know how to set the department name in the text field and refresh the screen. Any help is appreciated. Thank You.

Frank, thanks for you time. Please see my answers below.
Hi,
can you help me creating a reproducable testcase
based on the HR schema where we have a Departments
and Employees tables. To understand your usecase I
have some questions:
Im not too familiar with HR Schema.
>
First of all however, what is a "global view object",
and is it safe to assume you are using ADF Business
Components?
Its the "Globals View Object" as described in the SRDemo for creating a new Service Request and yes I am using ADF Business Components.
>
Which version of Oracle JDeveloper do you use ?
10.1.3
>
The usecase I understand is that you have a
selectOneChoiceList that whenever you select a new
name should update a read-only text field with the
department name. Is this correct ? Or is there more
in it ?
Heres the complete description. There are 4 fields on the screen
1. Program Name (text input field, - required field)
2. Program Category (SelectOneChoice field - required field)
3. Employee Name (SelectOneChoice field - required field)
4. Employee Department (Text output field - based on 3 above)
What you have described above is working for me now, but everytime I select a value for 3, it does the required fields check and gives a message like "1 & 2 are required and a value must be entered", this validation should only occur when my continue button is clicked.
>
The department name should be displayed only (read
only), or is it also bound to what you call "global
view"?
Yes its read only but I need to bind to the Globals view as I need to display it in the confirmation screen.
>
Also, just to be sure, is the department name part of
the VO or is it the departmentId?
The screen is bound to the Globals View, the selectOneChoice values are displayed from another view(EmployeeList view) which has the department name.

Need some help regarding validation of input in a text field

Hello everyone,
i am new to all this website designing stuff and is working on my first website (treausre hunt types) and expecting some guidance over here.   :-)
I have successfully managed to validate the login page using server behaviour.
Let me explain what i need guidance with.
After login , the user is redirected to a page where a question is asked and he has to type the answer in the given text field and click on the submit button. Now i want to validate the given answer with the correct one and if it is answered correctly then the user is redirected to the next page.
the question is what and how am i supposed to do this? i am using adobe dreamweaver cc and wampserver as localhost.

This becomes complicated to do it the way you want BUT YOU CAN do it - you just need to be a bit more efficient and get a template together.
Copy the 4 documents below and paste into seperate DW files to see how this works then look at the code and see if a pattern becomes noticeable to you. What we are doing is adding 1 to each level and checking the user has accumulated a score to that level - if not they are bumped down to the level which they have reached or in the case of not reaching any level to question 1.

Select List as a child to a text field?

I'm using APEX 4.1. I have a Select List that has a Cascading LOV Parent Item that is just another text field, the LOV sql has the text field in the where clause. When I type a few characters into the text field and tab to the Select List the list is filtered by the characters from the text field, but if I use the mouse and click the down arrow of the Select List I have to click twice before the list will be populated. Does anyone know why this is happening?

I would imagine it's a similar issue to the old 'mouse-navigate' in forms where no change event has fired while processing the arrow click. You may find different results in different browsers?
You may be able to solve your problem with a mouse-click DA on your select list? or something similar, who'se action refreshes that select list item.

Partial Page Refresh - Text Box Update

Hi,
I have a page where there are numerous regions, each containing two or more text fields. I want these to update periodically using partial page refresh.
I have got the partial page refresh working but my text fields are not being updated. How would I get them to update? I know I can't call a page process from javascript, only application processes.
Cheers
Simon

Hi John,
I think you'll need to create two dynamic actions. One of type PL/SQL block with null; as the source and enter the items to submit. The second is the Refresh Region Dynamic Action..

I tried to add new contect node for strategy & counter strategy (Relation BTTextIAll) but the save is not working properly.
Kindly suggest what needs to be done to make these standard text

Hi,
The issue is related to 'window.open("url")'. I replaced the above function with another script window.navigation("url).
When 'window.navigation' script is executed, browser is asking a security question whether to download the content or not. If i click yes, whole window is refreshed and existing data is gone. This happens only for first time when we try to download. After this the download is working fine without any session time out, if we are using the same window.
Kindly help if you have any inputs regarding the issue.
Thanks a lot.

Why am I getting visual artifacts when typing in text fields?

Since upgrading to Firefox 4, I get weird graphic artifacts when typing in text fields on websites. I'm getting them right now as I type this! They appear below and to the right of the line of text. The artifacts disappear when the page is refreshed or if the window is resized. This bug only happens in Firefox. My video card drivers are up to date.
Here is an example: http://i87.photobucket.com/albums/k136/tobe82/ff4bug.jpg

How to provide text formatting options to user from a text field

Hi,
My requirement is - in the interactive form, a comments field needs to be provided where user should be able to enter text with formatting options like
Headers
indentations
bold/italic
bullet points and numbers
Once user enters the formatted texts in a text field, data needs to be displayed/printed in the same format. Could you help me on how to provide these formatting options to the user for a particular text field?
I understand that once I define the text field with format XHTML (with RTF), user formatting can be captured and displayed in the same way. But I am not sure on how to provide the formatting options for the text field.
Thank you,
Madhu

Hi,
if you select a text field for Rich Text and the press Ctrl + E you'll get a bar for all available text formatting options in Acrobat/Reader.

Wrap a single word in a text field

Hello everyone!
I currently have a problem with text data that is displayed in a Flex text field <mx:Text>.
It's a narrow textfield (100px wide) in a animated ad banner that displays content from a database. There are some words that are too long for the available space, so flash wraps some letters to the next line. I have attached a screenshot that shows the actual problem.
The text is shown in a Java web-application as well, and since that Java app is displayed as a normale webpage, there is a lot more space for the text. I cannot put hyphens into the text because it would look weird in the normal web view.
Is there a way to make automatic hyphenation happening when Flash wraps a single word?
It would be perfect to get language-specific correct hyphenation, but a hyphen at the wrong spot is still better than no hyphen at all.
Thanks for your time and help!

I think your simplest bet would be to use mx:label and use the op
tion truncateToFit="true". Also adjust the width so that the text appears prope
rly. Hope this helps..!!
