Multi-row single table form

Hi,
Is is possible to create a portal form based on a single table which can display/insert multiple rows in a single action?
I have tried the custom display which supports displaying multiple rows. However, it sees these as duplicates since there is no way of specifying a distinction between each row, so only one row is inserted although values for multiple rows are entered.
Here's an example of the BODY section of my custom display:
<TABLE BORDER="0" CELLSPACING="0" CELLPADDING="0">
<TR>
</TR>
<TR>
<TD><#PARAMETER_NAME.LABEL#></TD>
<TD><#PARAMETER_VALUE.LABEL#></TD>
<TD><#PARAMETER_DESCRIPTION.LABEL#></TD>
</TR>
<TR>
<TD><#PARAMETER_NAME.ITEM#></TD>
<TD><#PARAMETER_VALUE.ITEM#></TD>
<TD><#PARAMETER_DESCRIPTION.ITEM#></TD>
</TR>
<TR>
<TD><#PARAMETER_NAME.ITEM#></TD>
<TD><#PARAMETER_VALUE.ITEM#></TD>
<TD><#PARAMETER_DESCRIPTION.ITEM#></TD>
</TR>
</TABLE>
</TD></TR><TR><TD>
This displays multiple rows, but I don't know if it's possible to use a special syntax so each rows values are seen as separate, e.g. _1 added after ITEM?
Any ideas??
Thanks in advance.

Gillian Channer

Hi,
This feature is not supported by Portal Forms right now. The only way you can do it is to create your own dynamic page.

JSF multi row editable detail form -- moving backwards or forward

Innocently trying to create an intuitive editable master detail JSF form. Similar to what you would want in any application and something that can be done in less than a minute in Oracle Forms
The master form is a just a simple editable single master form based on the dept table. and the detail is the emp table. I have create the model using the wizard and made sure a link view is created.
The details form is a multirow form with all the editable columns
I added two button for the details form (create, remove)
I entered the master record (no commit yet)
then i moved the cursor to the details form and created a few records, i found an error in the second row in the detail form, therefore, innocently, i selected that row and pushed the Remove button. shocked to find out that the first row in the details form is deleted regardless of which row is selected. Additionally, when a row is created using the create button, the row is created above the first row of the details form (as if the first row in the details form is always current).
Such requirement should be easily satisified by a Framework?

thank you frank for your response
Actually, my DETAILS form DOES include the Select Option, and i was really expecting (and accepting) the fact that i need to point to the row i need to delete. Actually, 20 years back i was 8080 assembly language programmer, and used to handle thing at very very low level. However, i do select a row, and i can see the Radio activated for that row, unfortunately though, the seemingly selected item in the DETAILS form is not the one that is removed, it is instead, the first row that is actually removed. It seems as if the form rows are not synchronized with the ROW selector you mentioned,, The first row is somehow internally selected (always)
This is the interesting part.
I created another project with a single multi row editable table (without master details) only a master, and guess what, it is working beautifully! exactly as you descirbed. Select a row, press delete and there you go, the record no longer exists

Change color multi-row highlite tabular form

I would like specific instructions on a quick way to change the highlite color when the multi-row check
box is chosen on a tabular form.
Thanks,
Sabrina

Sabrina,
To change the background color of the rows selected using the row selector, edit the report template youâre using, scroll down to row highlighting and type the color you like into the field labeled âBackground color for checked rowâ. You can type in the name of the color or the code.
Hope this helps,
Marc

Multi-Row Form Validations - Cannot Re-Use Phone Nos from select LOV

1) I need some help with a "Multi-Row" data-entry form (page 9)...I have a select list of phone-no's that user picks from the drop-down lov list on a page multi-row select list-drop down - P9_PHONE_ID (has built in lov). The data form is built on 'site_phone_assign' table.
However, I need to put a page-level validation where the user CANNOT select a pre-assigned phone id (reuse a phone) that's already been assigned (used) and a record exists in the site_phone_assign table. I built the following page level validation on the multi-row edit form which is built on 'site_phone_assign' table...NOT WORKING!
PLEASE HELP WITH THE BEST WAY TO DO THIS..Thanks!
--validation type: Function returning boolean
<code>
DECLARE
v_count pls_integer default 1;
BEGIN
IF (:P9_PHONE_ID IS NOT NULL) THEN
select count(*)
into v_count
from datahub.site_phone_assign s
where s.phone_id = :P9_PHONE_ID
and s.ASSIGN_START_DATE <= SYSDATE
AND NVL(s.ASSIGN_END_DATE,SYSDATE+1) >= SYSDATE;
END IF;
IF (v_count) > 0 THEN
RETURN (FALSE);
ELSE
RETURN (TRUE);
END IF;
END;
</code>
2) How can I apply validations on a multi-row edit form page where say - start_date is always less than end_date? Both start/end dates are date-picker type of items.
3) Can ITEM NOT NULL validation be applied on a multi-row edit page? I guess its page-level validation right? Please advice.
Edited by: Shravanv on Feb 18, 2010 1:50 PM

Hello,
In a Tabular Form you need to loop through the records on the screen, so doing a check on :P9_PHONE_ID doesn't work...
Patrick Wolf made a general solution for this problem, you can read about it here: http://www.inside-oracle-apex.com/plug-play-tabular-form-handling/

Multiple rows in a single table cell - Adobe forms

Dear All
I am developing an adobe form which conatins a table alongwith other screen/ form elements.
This table is bound to a data node and contains only two columns. Number of rows will be determined at run time.
Each cell of the table will contain three rows seperated by a space in between them. Please refer to the diagram below for more understanding.
Yes
ABC
No
PQR
Not Known

I have no idea how to achieve this. Can anyone help?
Regards
Vineet Vikram

Hi,
Here are the steps how you can do it.
1. Create a table.
2. In the Library palette, click the Standard category and drag the Table object into a cell in the main table.
Note: If you selected Donu2019t Show This Again in the Insert Table dialog box, when you select the Table object from the Library palette, LiveCycle Designer automatically inserts a table with the same number of columns and rows that you inserted the last time you used the Insert Table dialog box.
3. In the Insert Table dialog box, enter the number of columns and rows. You can enter a maximum of 20 columns and 50 rows. You can add more columns and rows after the table is created by using the Insert commands on the Table menu.
4. To add a header row, select Include Header Row In Table.
5. To add a footer row, select the Include Footer Row In Table.
6. Click OK.

Multi-row insert in master-detail tables

Hi, I'm using jdev 10.1.3.2 with jheadstart and my problem is:
I hava a master-detail structure, both are tables and my goal is that I want multi insert (exactly 3) in master and detail table when user makes new order(some business scenario). I cannot create rows in master or detail VO by overriding create() method because its entities have complex primary keys and some part of this key is populated by the user with lov. So I set in jhs new rows to 3 and checked multi-row insert allowed but the problem is that overall I can only create rows in master table after I submit form. I want to create row in master table and fill rows in detail table, and after that I want to have opportunity to create second (or even third) row in master table and fill rows in detail table.
thanks for help.
Piotr

See JHS DevGuide: 3.2.1. Review Database Design:
If you are in the position to create or modify the database design, make sure all
tables have a non-updateable primary key, preferably consisting of only one
column. If you have updateable and/or composite primary keys, introduce a
surrogate primary key by adding an ID column that is automatically populated.
See section 3.2.4 Generating Primary Key Values for more info. Although ADF
Business Components can handle composite and updateable primary keys, this
will cause problems in ADF Faces pages. For example, an ADF Faces table
manages its rows using the key of the underlying row. If this key changes,
unexpected behavior can occur in your ADF Faces page. In addition, if you want
to provide a drop down list on a lookup tables to populate a foreign key, the
foreign key can only consists of one column, which in turn means the referenced
table must have a single primary key column.

Exporting a single table from an acrobat created form

I created a 5 page document InDesign (CS5.5), On one page I created a table that is 4 columns x 25 rows (with the first row being a header), using the table feature. I then exported to pdf and finalized the form in Acrobat 9.2 Pro. After running the Form Field Recognition the table was populated with the appropriate fields. I finalized the form and distributed. When the form is returned to me, I am trying to export JUST the information in this table to a spreadsheet (employee name, title, phone, email, ) and do not seem to be able to do so. Is this possible from a form? It doesn't seem like the pdf recognizes this table as a table any longer. It is a list of attendees, so I want to take this list from each returned form and combine them all into a master list.
With the selection tool I have tried to select all the text > right click > Open Table in Spreadsheet and only the header rows appear. If I choose just the text and not the headers, then nothing appears. If I export the entire document then each cell of the table is its own column in excel, which makes sense since they all have different field names, but this doesn't make the spreadsheet useful. The only thing I have been able to do is select all the cells, copy into notepad, place a tab between each piece of information > save and open that document in excel. I am hoping there is an easier way. Basically all I am trying to do is have that table appear in excel as it does the pdf. I have searched several websites and have not been able to find anything that specifically deals with exporting a single table from a completed form.
Perhaps I need to set the table field names differently? Any assistance would be greatly appreciated.

The "table" idea here is just a design idea, the identity as a table no longer exists in a PDF. The feature you're trying to use is for tables which are part of the regular PDF, not form fields.
You can export form data. All fields, but then process to exclude the ones you don't want.

Issues in Table with Multi-Row Insert

I have created a master detail screens using jheadstart on 2 separate pages, Master in the Form layout and detail in the Table Layout with multi-row insert, update and delete flags ON. Have set the New Rows count = 2.
Issue 1
If I try to delete any existing rows, it gives error for new rows saying value is required for the mandatory fields. It should just ignore the new rows if I have not updated any values for any attributes in the those row(As it does for non Master-Detail Table layout). I guess this might be happening because the jheadstart code is setting the foreign key for new rows the detail, but not resetting the status of the rows back to INITIALIZED.
I also noticed that the create() of underlying EO is getting called for those blank rows when I click on 'Save' button, even if I have not changed any data in those rows.
Issue 2
When I try to select the new rows also for deletion, I am getting a '500 Internal Server Error' with following stack trace... This is also happening for normal (non Master-Detail) Table layout.
java.lang.IllegalStateException: AdfFacesContext was already released or had never been attached. at oracle.adf.view.faces.context.AdfFacesContext.release(AdfFacesContext.java:342) at oracle.adfinternal.view.faces.webapp.AdfFacesFilterImpl.doFilter(AdfFacesFilterImpl.java:253) at oracle.adf.view.faces.webapp.AdfFacesFilter.doFilter(AdfFacesFilter.java:87)
Issue 3
I have put some validation code in the validate() method in the MyEntityImpl.java class.
The validate method seems tobe getting called lots of times, in my case 20 times, where the new rows are just 2.
Environment:
Jdeveloper 10.1.3, JHeadStart 10.1.3 build 78, Windows XP
thanks

Thanks for the reply.
Issue 1:
What I have observed that in case of multi-row select enabled tables, the blank rows do not have any data. This is because the EO's create() method is called only when we post the data using 'Save' button. Thus the Foreign Keys are also not setup. This is a correct behavior since create() and FK setups etc should get done only if the user has inputted any value in the new rows and thus intend to insert new data into the table.
I am able to find the exact cause of this issue. It is happening because in the details table, I have a column which needs tobe shown as checkbox. Since we can only bind checkbox to an Boolean attribute in VO, I have created a transient attribute of type Boolean, which basically calls the getter/setter of actual attribute doing the String "Y"/"N" to true/false conversion. Here is code for the transient attribute getter/setter
public Boolean getDisplayOnWebBoolean() {
return "Y".equals(getDisplayOnWeb()) ? Boolean.TRUE : Boolean.FALSE;
public void setDisplayOnWebBoolean(Boolean value) {
if(Boolean.TRUE.equals(value))
setDisplayOnWeb("Y");
else
setDisplayOnWeb("N");
Now when I click on the "Save" button, the setter for the boolean field is getting called with the value = false and this is resulting into the row being maked as dirty and thus the validation for the required attributes is getting executed and failing.
Issue 2:
Confirmed that correct filter-mapping entries are present in the web.xml.
Now when I select the new blank rows for deletion and click save, following exception is thrown:
java.lang.ClassCastException: oracle.jheadstart.controller.jsf.bean.NewTableRowBean at oracle.jheadstart.controller.jsf.bean.JhsCollectionModel.getRowsToRemove(JhsCollectionModel.java:412) at oracle.jheadstart.controller.jsf.bean.JhsCollectionModel.doModelUpdate(JhsCollectionModel.java:604) at oracle.jheadstart.controller.jsf.lifecycle.JhsPageLifecycle.processModelUpdaters(JhsPageLifecycle.java:541) at oracle.jheadstart.controller.jsf.lifecycle.JhsPageLifecycle.validateModelUpdates(JhsPageLifecycle.java:571)

Tabular form - Multi row delete error

Apex 4.0.2
We have a simple CRUD type of application on a bunch of tables built using Apex v1.6 that has, over the years, been upgraded to v4.0.2 and it is working mostly fine. It uses all out-of-the-box standard components, forms, classic reports, nothing too fancy. Recently one of the tabular forms started to misbehave, the multi-row-delete process raises a No Data Found error. The tabular form is based on a view with a INSTEAD OF trigger to handle the DML. Manually deleting the row in SQL*Plus works fine delete from mytab here pk_id = :pk_id but selecting the same row in Apex and clicking Delete raises the error.
How does one go about troubleshooting & fixing this sort of thing? I tried re-saving the region in the Builder, exporting/importing the entire app, nothing. Running in Debug mode doesn't really provide any additional information, just that the MRD process failed. Tabular forms are the most frustrating, opaque component in Apex, wish they were easier to troubleshoot.
Any ideas?

Hello Vikas,
>> How does one go about troubleshooting & fixing this sort of thing?
By given us a bit more information :)
• Is it a manual Tabular Form (using the ITEM API) or a wizard created one?
• Are the Insert/Update operations work correctly? If not, what is the type of your PK column(s)?
• If the problem is limited to the Delete operation, maybe the problem lies with the checkbox column. Are you sure that on page it is rendered as the f01 column?
• As triggers are involved, can you save the PK that the trigger sees? Is it the expected value?
• Are there any other processes that are fired before the DML process? If so, maybe the problem is with them. You can temporarily disable them and see if it change anything.
>> Tabular forms are the most frustrating, opaque component in Apex, wish they were easier to troubleshoot
Yes, I agree. However, I believe that 4.1 made some serious advancement where Tabular Form is concerned. Having simplified Tabular Form related Validations and Process should make things easier, and as a result, prone to less errors. Still, the main problem is that the type of error you are talking about is usually the result of metadata problems and these are indeed very hard to track.

Arie.

Exporting form data to a single table

I have created a form in LiveCycle Designer ES 8.2 and simply want to export the data into a single table that I can then import into Access. It appears that in LiveCycle the row elements of a table are children of the table element and the column elements are children of the row elements. I am wondering if there is an easy way to design a form in LiveCycle so that each cell of a table is a root element like the rest of the fields in the form. I basically want to export one row of data from each form and append it to a larger table. Exporting the data as csv or tab-delimited would be sufficient, but neither of these appears to be an option.

The only way I've found to do this is to open the form in Acrobat, click Forms, mouse over Manage Form Data, then click Export Data. Your only options are to save as .xml or .xdp. I saved my data as .xml. I was then able to import the .xml file into excel by clicking Data, mousing over xml, clicking Import... and browsing to the Acrobat generated .xml file. I know this is convoluted but it's the only way I've found to get the data into a spreadsheet. Acrobat exports the data as filename_data.xml, i.e. a form named contacts will export it's data as contacts_data.xml. Be aware, I've only tested this on a form that had a table in it and nothing else. If your table is part of a form with other fields in it I have no idea how the other data will look after exporting.

Multi Row Form and onload

Hi,
I've a wizard based Multi Row Form (MRF) based on a view (on 2 tables) with Instead of triggers to handle the DML. I have an onchange event on one particular Select List based item in each row that simply disables/enables other row items depending on the value. All this is working fine, but I need to repeat the disable/enable of items for each row once the page has loaded.
My initial thought is to use an onload event in the Page definition, but can and should I be handling this in a Page Process instead (bear in mind that this is a wizard generated MRF)? Also, I need to ensure that new rows (via the Add Row button) are handled correctly. If I go down the onload event route, then is the simplest way just to get an array (getElementsById?) of the items and loop through them? Any thoughts would be most appreciated on the most efficient way to do this.
Cheers,
PaulB

Hi,
Yes, it appears the same as an onload but, fortunately, doesn't interfere with any existing onload code - you can only have one onload function call for the window object.
You can loop through the items on the form using something like:
function disableItems()
var x = document.getElementsByName("f03");
var y = document.getElementsByName("f04");
for (int k = 0; k < x.length; k++)
if (x(k).value == 'A')
y(k).disabled = true;
else
y(k).disabled = false;
}This assumes that the select list is in column 3 (which should mean that the SELECT objects should have a name attribute of "f03") and that the item you want to disable/enable is in column 4 ("f04") - so adjust as necessary.
As you have the same number of items in column 3 and column 4 - the above loops through the ones in column 3, checks the value selected and then disables/enables the item in the same row in column 4.

Multiple Users - Tabular Forms - Multi Row Update.....

Greetings All,
Any comments, assistance, links, or even answers on the following situation would be much appreciated....
I have a Application Express 4.0 (Could upgrade to 4.1 if it would help this issue)
I have a wizard generated tabular form on a table, the form will show up to 600 records (rows) on a page.
Part 1:
The situation:
User 1: Opens the form and brings up latest data set.
User 2: Opens the form and brings up the latest data set.
User 1: Changes data for record 1
User 1: Hits submit. The data is saved.
User 2: Changes data for record 1
User 2: Changes data for record 2
User 2: Hits submit. The following error is produced:
Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-20001: ORA-20001: Current version of data in database has changed since user initiated update process. current checksum = "3EE15D666E9DBDC59D34CE4CFB3950C0", item checksum = "922DA12AE1E3D8856695745C4D2830D2"., update "<Removed> Error Unable to process update.
When this error occurs no updates get made to the table.
I understand that row 1 can not be updated, however I would like row 2 (and all other rows where there is no conflict) to be updated. I would then like to be able to highlight in the form the rows that failed to update (And reload the data in them from the DB).
Is this something I can achieve using my own MRU procedure, or in another way?
Can anyone point me to a good example, tutorial or book showing how to do this.
Thanks!

Thanks for the comments guys.
I have solved my issue in two different ways. Way one was not so clever, but worked, involving writing my own process for handling multi-row updates and would allow a user to fill in data for multiple rows (say 10) and have only the row with changed data rejected. V2 takes a very different approach, it uses Javascript, AJAX and the DOM model of the form to check when data is changed / updated by the user. Essentially, when a user enters an updateable form element, a AJAX request checks if the data has been changed. If it has, the value in the form is updated, and the color changed to blue to alert the user. When the user updates the data item, and AJAX request posts the new value to the database, where it is inserted. I had to build a bit of a framework to make this useable, and have to use dynamic sql in the database packages, but it work really well for what my users need! There are limitations (Currently it only supports date fields, text fields and drop down lists) but it works for me. It also involves traffic back and forth with the server each time a user moves the focus to a new form element, but it is a very light request and the work to do the select / updates in oracle is all based on a primary ke, so is ver quick.
Solution 1: (Would need to be made much more elegant):
1: Create a new text Item called P5_MESSAGE (To display error / success messages)
2: Create a new process:
DECLARE
l_cks wwv_flow_global.vc_arr2;
j pls_integer := 1;
vUpdatedCount number := 0;
vErrorCount number:=0;
vMessage varchar2(4000):='';
BEGIN
select wwv_flow_item.md5(firstname,lastname,age) cks
BULK COLLECT INTO
l_cks
from VA_TEST1 ;
for i in 1..l_cks.count
loop
if htmldb_application.g_fcs(i) != l_cks(i) then
-- Log error
vErrorCount:=vErrorCount+1;
vMessage:=vMessage||'Could not update row with ID:' || htmldb_application.g_f01(i) || '. This data has been updated by another user since you retrieved the data.<br>';
else
-- Do insert
vUpdatedCount:=vUpdatedCount+1;
update VA_TEST1
set
FIRSTNAME = replace(htmldb_application.g_f02(i),'%'||'null%',NULL)
,LASTNAME = replace(htmldb_application.g_f03(i),'%'||'null%',NULL)
,AGE = replace(htmldb_application.g_f04(i),'%'||'null%',NULL)
where ID = htmldb_application.g_f01(i);
end if;
end loop;
:P5_MESSAGE := vMessage;
end;
Note, this currently updates every row, even if the data is unchanged, this could be fixed by comparing the checksum of the data to be inserted with the checksum of the data in the table, if the same then no need to insert.
Solution 2:
Too complex to explain in detail here, if you need to implement this then let me know.
