Form with variable number of fields?

I need to write a data entry form in JSF. It's the standard kind of things, a series of labels and textFields and checkboxes and so on.
The number of items is not known in advance. It is data-dependent. There might be 1 label-value pair sometimes and 10 label-value pairs another time, depending on the data.
To do this in JSF would I have to write a custom component? Using JSP and JSTL tags I would write a <c:forEach> loop, but it seems like that's not the right thing to do in JSF. Does anybody have experience with this, or an example that could get me started? Thanks.

I think the table would handle the layout and repetition of rows. But if some of the input fields are text input and some are checkboxes or another type, how would I get the right type of input on each row? Do you have an example where the backing bean dynamically builds components, that I could look at? Thanks.

Need to generate PDF file from OAF with "n" number of fields

Hi All,
I have a requirement in OAF to generate PDF file with n number of fields in PDF output. PDF output could have some times 2 fields or 3 fields or 7 fields too in some condition and it will be based on one parameter. This output will be looks like below given scenarios:
Example Scenario I
Emp No | Emp Name | Dept No | Job |
11 | Abc | 10 | MGR |
Example Scenario II
Emp No | Emp Name |
11 | Abc |
Please let me know if any one know how to go about it.
Thanks in advance,

Display table with variable number of columns

Hello Forum,
I'm trying to build an export view of User Management Engine data. I would like to output a table with one row for every user with yes / no fields indicating membership in each of the available groups. Because the number of available groups might change in the future, I can't hardcode the column names for the groups.
That is, I call a webservice to compute a table, and I get back a table with a variable number of columns.
When I try to insert the webservice into my VC model, it complains:
"Port 'Response' was omitted because it includes nested tables, which are not presently supported by Visual Composer"
You might be interested to know that the business method of my webservice (for testing purposes) looks as follows:
public String[][] getVariableSizeArray() {
        String[][] ret = new String[10][];
        for (int i = 1; i <= 10; i++) {
                ret<i> = new String[10];
                for (int j = 1; j <= 10; j++) {
                        ret<i>[j] = Integer.toString(i * j);
        return ret;
Any help is appreciated, and points will be awarded for helpful answers,
Sincerely,
Florian

Hi Florian,
dynamic data structures are not supported. You can do this with a workaround. If you know the maximum count of your columns then you can add them to the table and hide/unhide them dynamicly via a formula in the hidden condition. Of course in your WS you als need a fix structure of your columns.
This is not the best solution, I know so far, but it works. This is just one limit of VC.
Best Regards,

ALV column with variable number of decimals to be displayed

Hi,
I've an ALV where I need to display a numeric column with a variable number of decimal row-by-row, from 0 (no decimals) to 4.
I've declared the numeric field as TYPE P DECIMALS 4.
I've tried with DECMLFIELD in ALV catalog, and this works for 1 to n decimals, but when I leave the field indicated in DECMLFIELD equal to 0, ALV shows the default number of decimals of the field (4 in that case).
Any help will be very appreciated.
Thanks.
Jordi

No, I didn't try EDIT_MASK.
How should I use it to format output to display decimals or not depending on the row?
I have 2 kinds of values, all stored in a TYPE P DECIMALS 4: Those that really are an integer (decimals should not be displayed for that ones) and the values that really have 4 decimals (which should be displayed with decimals in ALV).
Example:
13,0000 should be displayed as 13
0,4567 should be displayed as 0,4567
With EDIT_MASK could I do that?
Thank you very much.

Procedure with variable number of columns

Hi, I have a procedure that looks like this:
PROCEDURE PROC(p_cursor OUT sys_refcursor)
And in the procedure, I build up QUERY dynamically and the number of columns varies at runtime.
At the end I do
OPEN p_cursor for QUERY
Then to call this, I'm doing
call PROC(?)
My question is, how would I go about running the query from this procedure, then adding rows or modifying the existing results, then returning the modified data?
What I want to do is add a new row based on some condition, so I still need to return a variable number of columns, but I need to modify the results before I return them.
Is there any way of doing this? I need to do some calculations on the columns (the variable columns), create a new row, insert into result set, and return this new result set.

A sys_refcursor is ideally suited to pass back to a front end gui like .NET or Java which can then use that cursor to retrieve the data.
In PL/SQL there is no point in using a sys_refcursor unless you know, at design/compile time what the returned columns are going to be.
If the resultant columns are dynamic, then you have no choice but to use the DBMS_SQL package, where you can parse and execute any SQL statement you like and then use the DBMS_SQL package to describe what the resultant columns are and how many there are. From that you can reference the columns by position rather than by name.
e.g.
CREATE OR REPLACE PROCEDURE run_query(p_sql IN VARCHAR2) IS
v_v_val     VARCHAR2(4000);
v_n_val     NUMBER;
v_d_val     DATE;

d           NUMBER;

SQL>In 11g, you can create a sys_refcursor and then the DBMS_SQL package allows you to convert that refcursor into a DBMS_SQL cursor so that you can get the description of the results and do the same. This isn't available prior to 11g though.
However_ before any of that, you should really ask yourself if there is a real need to dynamically be creating queries. There is rarely any real need to do that and if you're finding it's common in your application then this is often a sign of poor design or poorly defined business requirements (leaving the technical side to try and be "flexible" and hence leading to unmaintainable code etc.).

Tabular form with non base table field

I want to develop a tabular form with
1. A non-base table edit field to accept a value
2. Insert/update another table based on the input value
3. Also, computed field on each row based on other fields on the records (like post-query trigger in oracle forms at block level - for each row)
Thanks,
Rachna

Thanks for your reply.
Varad, I like the link you sent me. It has a lot of good information.
I created a process (under page processing) called "Update/Insert Process" that dosn't seem to be working.
Question, I created a manual tabular form with SQL Query and created a process (under page processing) called "Update/Insert Process", then I check for each record in the tabular form. If the old value <> new value then I update/insert in the new table.
Any step by step will be highly apprciated - to create process/validation etc.
Thanks,
Rachna

Save form with data from a field

Hi,
Is there an option to save the form with the data from one of the fields?
Example:
form field "Name", user enters Will William.
Can I use this to autmatically save the form in the end as "Will William" and choose the save location?
Thanks

That's possible, but it requires privileged JavaScript code. This means code that's either in a folder-level JavaScript file or in a certified document that is trusted to execute privileged JavaScript. For more information, see the following tutorial: http://acrobatusers.com/tutorials/how-save-pdf-acrobat-javascript

Form with only 1 text field + ENTER: Error 404

I have several JSP pages with forms to enter/edit data. As long as I use the mouse to click the submit buttons, I get no errors. If the form has more than 1 text field to enter, i can also edit one of these text fields and press the ENTER/RETURN key which has the same effect as the submit button clicked with the mouse. But if a form just has 1 text field, I get the following error when I press the ENTER/RETURN key (instead of clikcing the submit button with the mouse):
Error 404--Not Found
From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.4.5 404 Not Found
The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.
This is the same case on all JSP pages that only has 1 text field: they work when using the mouse by pressing the submit button but fail when using the ENTER/RETURN key.
Is this a known bug? Is there a workaround for this?

I believe that text inputs can have their own action
attribute, so providing the same value there as in
the form may help (though by default it should defer
to the form's action).
So try something like:
<form action="x.jsp">
<input type="text" name="..." action="x.jsp"/>
</form>
That doesn't help. The addresss bar is also always the same as the jsp pages are displayed in a html frame.

How to code spark custom component with variable number of (skin)parts?

Hello. I'm trying to code a complex Spark custom component that may have a variable number of parts. To help you understand the requirements, the component can be visualized as an HSlider with a unlimited number of thumbs (as opposed to one).
How do I, in general, represent these thumbs in the host component as well as the skin? If I had a fixed number of thumbs, say 5, I could easily represent them as 5 button SkinParts declaratively. However, it's not immediately clear to me how to deal with a variable number of them.
I've studied the HSlider implementation as well as other components and can't find an example that fits this pattern. The closest thing that I can think of is to represent the thumbs as a DataGroup and provide a custom item renderer to render them. Couple that with the general HSlider behaviors that I need to preserve, such as the fairly involved local/global coordinate translations, I don't know whether the approach will work.
Any better ideas? Thanks.

#2 sounds utterly strange to me. How would I utilize the phase id?The code below shows my idea whereas I never validate it in any real projects:
public class MyPhaseListener implements PhaseListener {
     private static final String IDKEY = "PHASEID";
     public static PhaseId getCurrentPhaseId() {
          return (PhaseId) FacesContext.getCurrentInstance().getExternalContext().getRequestMap().get(IDKEY);
     public void beforePhase(PhaseEvent event) {
event.getFacesContext().getExternalContext().getRequestMap().put(IDKEY,event.getPhaseId());
     public PhaseId getPhaseId() {
          return PhaseId.ANY_PHASE;
}You can write your constructor like as:
if (MyPhaseListener.getCurrentPhaseId().equals(PhaseId.RENDER_RESPONSE ) {
     /* create children because this is the first time to create the component */
}

Master-detail reports with variable number of pages in a big report

I am designing with Reports 6.0.5.32.0 a master-detail report such as a
combination between a customer with his name, address etc, at the top of
the page (always 60% of the first page) and then as details lines with his orders.
For one customer seems relatively OK with the variable number of pages in accordance with the number of his orders.
When the main query finds more customers I present always the customer at the top of
a new page (that's easy), but how can I control the number of the next pages for the orders, variable for every customer.
I can not predict how many pages are necessary for a customer and white pages are
not desirable. When the number of Max. Vertical Body Pages is too low I can get the next pages for every customer, but appears an
uncontrollable shift to the left.
For instance, a customer with 40 orders needs 3 pages, one with 4 orders only 1 page, one with 15 orders 2 pages, etc.
What's the magic property for a secure and precise layout?

Hi Andreas,
did you try setting vertical spacing to expand or variable on master repeating frame (and posible other frames surrounding master repeating frame)?
Hope this helps

Creating a form with variable table name(s)

non-database table and use record group to read from the base
table of each user.(All the tables in question have the same
structure).
Record group is a read only, and I want to be able to do data
maninpulation with this form.
The questions are
(1) It possible to do data manipulation with record group and if
it is, how?
(2) Is it possible to build a form with a variable table name?
if possible, how?
Somebody pls help.

Hi,
you can create and manipulate record groups at runtime(see Forms
Reference 'Create_Group' and 'Add_Group_Row') don't use
Create_Group_from_Query. For your purpose it's better to build a
cursor loop on your Query and add your datas after
manipulating with 'Add_Group_Row' to your Record Group.
It's possible to SET_BLOCK_PROPERTY(QUERY_DATA_SOURCE_NAME) but
it's not possible to change the item property 'Column Name'.
Therefor I would suggest to build a non database block and
populate these block by a programm unit, which works with a
pl/sql cursor loop and the 'create record' to populate these
block.

Can we write function with variable number of argument

Hi
Can anybody tell that can we pass variable number of arguments to a function in oracle 10gR2.
As in function decode we can pass variable no. of arguments upto 255 arguments, similarly can we creat a function which accept any no. of variables.

I'm not sure that this is what you were asking about, but depending on the logic you want to implement, you can declare the maximum possible number of parameters to your function, give them default values, and then pass to your func as many parameters as you want:

Submiting a form with variables packed into an associative array

I have a complex form created in flash that submits to a
shopping cart. I was having trouble getting the variables in the
right format for the shopping cart to accept.
So I created a bridging script in php that fills in the
hidden fields of a form then uses javascript to submit it to the
cart. This works but I would like to submit the variables directly
to the cart and eliminate the need for a bridge.
At the moment I am simply using
getURL("bridge.php", "_self", "POST");
to POST the variables to the bridge.
The bridge code is
<?php
$id[txt_1] = "$colortext";
$id[txt_2] = "$xheight";
$id[txt_3] = "$xwidth";
$id[txt_4] = "$nopanels";
$id[txt_5] = "$shutterstyle";
$id[txt_6] = "$squarearea";
$id[txt_7] = "$finish";
$id[txt_8] = "$bifoldoption";
$id[txt_9] = "$slidingoption";
$id[txt_10] = "$hingedoption";
$id[txt_11] = "$totalprice";
$id[txt_12] = "$colorcode";
$products_id = "28";
?>
<form
action="product_info.php?products_id=28&action=add_product"
method="post" name="MyForm" target="_self">
<input type="submit" name="Submit" value="Submit">
<input name="id[txt_1]" type="hidden" value="<?php
print($id[txt_1]); ?>">
<input name="id[txt_2]" type="hidden" value="<?php
print($id[txt_2]); ?>">
<input name="id[txt_3]" type="hidden" value="<?php
print($id[txt_3]); ?>">
<input name="id[txt_4]" type="hidden" value="<?php

<script type="text/javascript"

I am trying to create in flash 8 the equivalent of the above
form using the function below.
function submitvars() {
var id: Array = new Array();
id.txt_1 = colortext;
id.txt_2 = xheight;
id.txt_3 = xwidth;
id.txt_4 = nopanels;
id.txt_5 = shutterstyle;
id.txt_6 = squarearea;
id.txt_7 = finish;
id.txt_8 = bifoldoption;
id.txt_9 = slidingoption;
id.txt_10 = hingedoption;
id.txt_11 = totalprice;
id.txt_12 = colorcode;
var myvar:LoadVars = new LoadVars();
myvar.id = id;
myvar.products_id = '28';
myvar.send("product_info.php?products_id=28&action=add_product",
"_self", "POST");
So far the variable products_id = ‘28’ transfers
over to the cart fine but not the variables in the ‘id’
array

You're welcome.
I've never used register globals, couldn't figure that out,
thanks for explaining.
The other way to do it if you want to send an array of simple
data (usually all of one data type like string or number) is to use
array.join("delimiter_sequence"); in flash. You can then assign it
to a single property of your loadvars (e.g. 'id') and use explode
in php with the same delimiter to recreate an array. This does not
give you an associative array though, just a regular numeric
indexed one.
To send complex data like arrays and objects, you can use
other encoding techniques. You can even use json: json.org has a
json class(es) for flash and php 5 has json encoding/decoding
support for example.
Another way is to use amfphp and remoting, which does all the
work for you. And of course, you have XML support as well at both
ends, so you can always represent complex data in XML if you
prefer. You may want to investigate these or other methods on
future occasions.
