APEX FORM columns disable/enable?

Hello there,
Actually i have an application with two forms (means two screen for same application) based on views including 82 fields and everything working perfect whatever i wanted but I have a question?
in my application only few (say 8 field ) are pre-populated and rest are them need to populated but one field will decide which fields are need to be updated. for example field called CODE will accept value between 11 and 15 and if it is 11 and 12 then populate only Controlled table_ via views and if it is between 13 and 15 then Uncontrolled table_ will be updated. So I want if code is 11 and 12 then all the uncontrolled fields should be disable and vice versa. so can anyone help me for my query?
Thanks in advanced.
Iki

How to insert data from APEX form into two tables

Hi,
I'm running APEX 4.1 with Oracle XE 11g, having two tables CERTIFICATES and USER_FILES. Some of the (useless) fields are cut to reduce information:
CREATE TABLE CERTIFICATES
CERT_ID NUMBER NOT NULL ,
CERT_OWNER NUMBER NOT NULL ,
CERT_VENDOR NUMBER NOT NULL ,
CERT_NAME VARCHAR2 (128) ,
CERT_FILE NUMBER NOT NULL ,
) TABLESPACE CP_DATA
LOGGING;
ALTER TABLE CERTIFICATES
ADD CONSTRAINT CERTIFICATES_PK PRIMARY KEY ( CERT_ID ) ;
CREATE TABLE USER_FILES
FILE_ID NUMBER NOT NULL ,
FILENAME VARCHAR2 (128) ,
BLOB_CONTENT BLOB ,
MIMETYPE VARCHAR2 (32) ,
LAST_UPDATE_DATE DATE
) TABLESPACE CP_FILES
LOGGING
LOB ( BLOB_CONTENT ) STORE AS SECUREFILE
TABLESPACE CP_FILES
STORAGE (
PCTINCREASE 0
MINEXTENTS 1
MAXEXTENTS UNLIMITED
FREELISTS 1
BUFFER_POOL DEFAULT
RETENTION
ENABLE STORAGE IN ROW
NOCACHE
ALTER TABLE USER_FILES
ADD CONSTRAINT CERT_FILES_PK PRIMARY KEY ( FILE_ID ) ;
ALTER TABLE CERTIFICATES
ADD CONSTRAINT CERTIFICATES_USER_FILES_FK FOREIGN KEY
CERT_FILE
REFERENCES USER_FILES
FILE_ID
NOT DEFERRABLE
What I'm trying to do is to allow users to fill out all the certificate data and upload a file in an APEX form. Once submitted the file should be uploaded in the USER_FILES table and all the fields along with CERT_ID, which is the foreign key pointing to the file in the USER_FILES table to be populated to the CERTIFICATES table. APEX wizard forms are based on one table and I'm unable to build form on both tables.
That's why I've created a view (V_CERT_FILES) on both tables and using INSTEAD OF trigger to insert/update both tables. I've done this before and updating this kind of views works perfect. Here is where the problem comes, if I'm updating the view all the data is updated correctly, but if I'm inserting into the view all the fields are populated at CERTIFICATES table, but for USER_FILES only the fields FILE_ID and LAST_UPDATE_DATE are populated. The rest three regarding the LOB are missing: BLOB_CONTENT, FILENAME, MIMETYPE. There are no errors when running this from APEX, but If I try to insert into the view from SQLDeveloper, I got this error:
ORA-22816: unsupported feature with RETURNING clause
ORA-06512: at line 1
As far as I know RETURNING clause in not supported in INSTEAD of triggers, although I didn't have any RETURNING clauses in my trigger (body is below).
Now the interesting stuff, after long tracing I found why this is happening:
First, insert is executed and the BLOB along with all its properties are uploaded to wwv_flow_file_objects$.
Then the following insert is executed to populate all the fields except the BLOB and it's properties, rowid is RETURNED, but as we know RETURNING clause is not supported in INSTEAD OF triggers, that's why I got error:
PARSE ERROR #1918608720:len=266 dep=3 uid=48 oct=2 lid=48 tim=1324569863593494 err=22816
INSERT INTO "SVE". "V_CERT_FILES" ( "CERT_ID", "CERT_OWNER", "CERT_VENDOR", "CERT_NAME", "BLOB_CONTENT") VALUES (:B1 ,:B2 ,:B3 ,:B4, ,EMPTY_BLOB()) RETURNING ROWID INTO :O0
CLOSE #1918608720:c=0,e=11,dep=3,type=0,tim=1324569863593909
EXEC #1820672032:c=3000,e=3168,p=0,cr=2,cu=4,mis=0,r=0,dep=2,og=1,plh=0,tim=1324569863593969
ERROR #43:err=22816 tim=1324569863593993
CLOSE #1820672032:c=0,e=43,dep=2,type=1,tim=1324569863594167
Next my trigger gets in action, sequences are generated, CERTIFICATES table is populated and then USER_FILES, but only the FILE_ID and LAST_UPDATE_DATE.
Finally update is fired against my view (V_CERT_FILES), reading data from wwv_flow_files it populates BLOB_CONTENT, MIMETYPE and FILENAME fields at the specific rowid in V_CERT_FILES, the one returned from the insert at the beginning. Last, file is deleted from wwv_flow_files.
I'm using sequences for the primary keys, this is only the body of the INSTEAD OF trigger:
select user_files_seq.nextval into l_file_id from dual;
select certificates_seq.nextval into l_cert_id from dual;
insert into user_files (file_id, filename, blob_content, mimetype, last_update_date) values (l_file_id, :n.filename, :n.blob_content, :n.mimetype, sysdate);
insert into certificates (cert_id, cert_owner, cert_vendor, cert_name, cert_file) values (l_cert_id, :n.cert_owner, :n.cert_vendor, :n.cert_name, l_file_id);
I'm surprised that I wasn't able to find a valuable source of information regarding this problem, only MOS note about running SQLoader against view with CLOB column and INSTEAD OF trigger. The solution would be to ran it against base table, MOS ID 795956.1.
Maybe I'm missing something and that's why I decided to share my problem here. So my question is how do you create this kind of architecture, insert into two tables with a relation between them in APEX ? I read a lot in the Internet, some advices were for creating custom form with APEX API, create a custom ARP, create two ARP or create a PL/SQL procedure for handing the DML?
Thanks in advance.

Sve

Thank you however I was wondering if there was an example available which uses EJB and persistence.

Excisable Column Disabled

Hi Experts,
Previously i was using SAP B1 2005B PL40. But now i have upgraded to SAP B1 2007B PL10.
Now in 2007 B PL10 i am facing a problem. In the SO, Delivery & A/R Invoice template the Excisable Column is Inactive.
Even in the form setting i have checked , it is showing the Visible column as enable but the Active column is disable.
Is there any idea of SAP behind this change. If not then guide me how to make the Excisable Columns as Active in the SO, Delivery & A/R Invoice template.
Thanks and Regards,
S Manikandan

Passing variable from a APEX form to PL/SQL Open link in a new borwserwin

Hello Everyone,
I got a apex form based on a query like :
"INTERFACE_NAME",
"INTERFACE_NAME" INTERFACE_NAME_DISPLAY,
"PRIORITY",
"HAS_STARTED",
"EMAIL_TO",
"STATE",
from "#OWNER#"."INTERFACES"
where "INTERFACE_NAME" = :P2_INTERFACE
only the field state is updateble.
It's just allowd to update the data in the DB-table with a PL/SQL Procedure:
begin
set_interface_vals@DB (p_interface_name => :INTERFACE_NAME, p_state => :STATE);
end;
I did put the prodzedure in a Page Process which act with a submit button.
Now to my problem: how do I get the values of my fields INTERFACE_NAME and STATE. the way I done it here does not work.
Thanks for you help.
regards sia
Edited by: sia on Mar 14, 2011 5:46 PM

well then , you should be looping over the record invoking that package for each row. Your package handles only one row, isn't it ?
The first thing your should do is find the names of the column fields interface name and state. Open the page source or check it in firebug by looking inside the appropriate columns. The html code will be something like <input type="text" name="f01" value="" />
<input type="text" name="f01" value="" /> with the name attributes in the format fXX (01 to 50)
I am assuming that the interface name has it as f01 (XX=01) and state is f02 (XX=2), each of which corresponds to an application array(having as many elements as there on the page) by the name "APEX_APPLICATION.G_FXX"
BEGIN
FOR i IN 1..APEX_APPLICATION.G_F01
LOOP
set_interface_vals@DB ( p_interface_name => APEX_APPLICATION.G_F01(i) --ith row's interface column value
,p_state => APEX_APPLICATION.G_F02(i) --ith row's state column value
END LOOP;
END;

Java Script Disable/Enable Items Problem

Hi,
I followed the directions to disable/enable items from http://www.oracle.com/technology/products/database/htmldb/howtos/htmldb_javascript_howto2.html#disable.
And I'm getting an error.
I have fields like :
Issue Summary
Issue Description
Identified By
Identified Date
Status (Values: Open, On-Hold, In-Process, Closed)
Priority
Target Resolution Date
Whenever the Status changes to 'In-Process' I would like to disable 'Issue Summary and Issue Description'.
Both the fields (Issue Summary and Issue Description) are being disabled when the Status changed to 'In-Process'
but when I click the 'Apply Changes' button I'm getting the error: 'Issue summary cannot be null.'
I do have a Not Null validation on Issue Summary field, but I'm only updating the Status field.
Following is the JavaScript:
In the Page Attribute (HTML Header)
<script language="JavaScript" type="text/javascript">

// This function takes in:
// 1. A string expression to evaluate. For example:
// 'document.getElementById(\'P125_STATUS\').value=InProcess'
// Notice the quotes are escaped using a "\"
// 2. One or more arguments which are item ID's as strings. For example:
// ...,'P1_ENAME','P1_SAL'...);
// Notice the ID's are the item names, NOT item labels
function disFormItems(testString,P125_ISSUE_SUMMARY,P125_ISSUE_DESCRIPTION){
theTest = eval(testString);
if(theTest){
for(var i=1;i<4;i++){
if (arguments){
disItem = document.getElementById(arguments[i]);
// disItem.style.background = '#cccccc';
disItem.disabled = true;
else{
for(var i=1;i<4;i++){
if (arguments[i]){
disItem = document.getElementById(arguments[i]);
disItem.disabled = false;
// disItem.style.background = '#ffffff';
//-->
</script>
In the Footer:
<script language="JavaScript1.1" type="text/javascript">
disFormItems('document.getElementById(\'P125_STATUS\').value==\'In-Process\'','P125_ISSUE_SUMMARY','P125_ISSUE_DESCRIPTION');
</script>
In the Status field HTML Form Element Attributes:
onChange="javascript:disFormItems('document.getElementById(\'P125_STATUS\').value == \'In-Process\'','P125_ISSUE_SUMMARY','P125_ISSUE_DESCRIPTION');"
Can somebody let me know what's wrong?
Any help is greatly appreciated.
Thanks in advance

FYI: I used the following JavaScript to make it work:
In the Header Text
function SetReadOnly()
var status = document.forms[0].p_t09.value;
if(status == 'In-Process')
document.forms[0].p_t02.readOnly = true;
document.forms[0].p_t03.readOnly = true;
//-->
In the Footer
<script language="JavaScript1.1" type="text/javascript">
SetReadOnly();
</script>
In the HTML Form Element Attributes
onChange="javascript:SetReadOnly();"
Thank you very much for your suggestion

V4.0 Dynamic Action - Problem with implementing disabling/enabling button

I'm having trouble implementing the following APEX V4.0 dynamic action:
The enabling/disabling of a button when a text field is not-null/null.
I'm following the example in Oracle's Advanced APEX course notes Pgs 5-13 to 5-16. I can get it working with no problems using two text fields. The example states that the "Select Type" for the button is a DOM object and you then have to enter it's name in "DOM Object" attribute. The example uses a "CREATE" button in a region position. Is "CREATE" just the Name attribute of the object? Is that what we are suppose to enter here? Also my FIND button is a "button among the region items" and not a "button in a region position" as in the example. The name of the button is P1_PAT_TBRN_SEARCH but when I use it as the Dom Object, nothing happens. Also I am using the "Key release" event for the text field that must be not-null.
I notice that Demitri Gielis on his blog couldn't get it working either (see last paragraph)
http://dgielis.blogspot.com/2010/01/apex-40-dynamic-actions-part-1.html
Any suggestions?
thanks in advance

Edited by: PaulP on Jun 2, 2011 12:01 PM

Hi Paul
Two separate situtations here:
- html buttons
- template based buttons, typically comprising multiple html elements
HTML Buttons
These should be easy to enable/disable using dynamic actions, specifying an appropriate DOM selector.
Typically you would use the ID attribute of the button, so that's straight forward except for one catch..
APEX supports a #BUTTON_ID# template substitution tag , but performs substitutions only for buttons in Region positions and not for button items.
Use button attributes instead to assign a specific ID.
Template Buttons
Since these are made up of multiple elements, you need to treat them as a single object to be able to interact with them easily.
APEX provides the apex.widget.initPageItem method to integrate plugins with the dynamic actions framework:
apex.widget.initPageItem("P1_MY_ITEM", {
enable: function(){},
disable: function(){},
getValue: function(){},
setValue: function(){},
nullValue: "%null%"
});This provides you with a mechanism to over-ride one or all of these built-in methods with your own JS, to use custom code to enable/disable your template buttons.
For an example on how this works, look in the uncompressed apex_widget_4_0.js file, search for the shuttle widget.
You could just add code to initialize your template buttons manually, or better still create a plugin button to add the code automatically.
This is reasonably advanced work to do, but you really have to take your hat of to the APEX team for providing the mechanism to do it.

Mark

Database Trigger gives error in APEX form

Hi
I have a table that has an on insert and on update trigger on the database table that is in the apex form. when applying changes or creating a new row fields are populated in the table for who and date. This works as expected but not in APEX.
in apex when trying to create or apply changes the following error is given
ORA-20505: Error in DML: p_rowid=hello, p_alt_rowid=ID, p_rowid2=, p_alt_rowid2=. ORA-06502: PL/SQL: numeric or value error: character string buffer too small ORA-06512: at "AIT_MSTR.UPDATE_ACCOUNT_ROW", line 9 ORA-04088: error during execution of trigger 'AIT_MSTR.UPDATE_ACCOUNT_ROW'
Error Unable to process row of table ACCOUNT.
I am not sure, but I think this error is around the DATE field in the row. How can APEX be modified to not error out on the execution of the trigger?
the trigger is very simple
CREATE OR REPLACE TRIGGER AIT_MSTR.UPDATE_ACCOUNT_ROW

Any help is greatly appreciated

Hi
Yes you are correct it was the length of the Created_by and Updated_by column. i had to increase the size of those columns in the table
Now it works.
HOWEVER, it is not capturing the user name of the person logging into APEX that is creating or updating the record. The entry I see in the created_by or updated_by is ANONYMOUS. Which is not want is needed to be captured and recorded. Where is this anonymous value coming from and how can i get it to be the id of the APEX user instead?
Any help is greatly appreciated on this new issue

External Speakers Randomly Stop Working until I "Test" or Disable/Enable

I'm using a HP Pavillion DV6 Notebook PC Running Windows 7 Professional 64-bit SP1.
External speakers randomly stop working until I "test" or disable/enable them. Headphone/HDMI Audio Works.
Background
-Recently had to do a clean install of windows.
-Went to the HP Drivers Website and downloaded all of the latest drivers.
-I installed several other programs as well (Flash, Steam, Media Player, Browser)
-The problem started
Current Settings
-My deafult device is "Speakers and Headphones: IDT High Definition Audio CODEC"
-Enhancements are disabled
-Bass and Treble are set to 4
-Format is set to 16 bit, 48000 Hz (DVD Quality)
-Allowing applications to take exclusive control of the device or not doesn't make a difference (but it's currently off)
Troubleshooting
-The audio works by plugging in headphones or using an HDMI device
-The audio comes back if I go to my sound settings and hit "Test", or if I disable and re-enable the device
Error Messages
-Youtube starts the video for 3 seconds, restarts and sputters a bit, and then says that there was an error
-My media player (MusicBee) gives me this message: "Unable to start playback (Error = BASS_ERROR_BUFLOST)"
That's everything I can think of. Any ideas?

Changing tabular form column to checkbox

I have a tabular form in 3.2. There is a column that is a text field, but really should be a checkbox. I have tried changing the region source to something like, select a, b, APEX_ITEM.CHECKBOX(3, PRIMARY FLAG) "PRIMARY_FLAG", d
from my_table
WHERE a = :P52_XPROD, but the column still shows up as a text field, displaying a value like "<input type="checkbox" name="...etc.
Is it possible to change a tabular form column to a checkbox in 3.2?

edit your report attributes, then edit your column and change "display as" to "standard report column"

Calling a .rdf report from a link on a apex report column

Hi,
I want to call a xxx.rdf report from a link on a apex report column.
Can anyone help me on this ?
Best regards,
JCN

Hi,
Sorry - I should have read a bit further in your last post!
The url variable that you're defining should just be the URL string that you want to create, so you only need the "http://........" part. There's also a + missing after the "&TODT..." string.
The "DEA_PERMIT_ID=&G_PERMIT_ID." part at the end should have an & at the start to indicate a new parameter in the URL. Otherwise, &G_PERMIT_ID. would be replaced by the value stored in the session for the G_PERMIT_ID item (presumably that is an Application Item?).
So:
function callPopup()
var url = "'http://snapper.accsp.org/reports/rwservlet?destype=cache&desformat=PDF&report=edr_landings_dollars_by_vessel.rdf&userid=evtr_report/chicken99@safis&FROMDT=" + $v("P810_FROM") + "&TODT=" + $v("P810_TO") + "&DEA_PERMIT_ID=&G_PERMIT_ID.";
popupURL(url);

How to implement enter-query , execute-query in Apex Forms

Hi,
I am new to Oracle Application Express. I want to know what is the equivalent of ENTER-QUERY and EXECUTE-QUERY features of Oracle Forms in Oracle APEX? I saw a lot of documentation, but everywhere I found that APEX forms only have 3 database actions, (1) INSERT (2) UPDATE & (3) DELETE.
Does anybody know how we can do QUERY in APEX Forms? (like we do in Oracle Developer Forms).
Thanks in advance.

Oracle APEX is a web/ stateless environment. So you do not have the same functionality/ features as in a Oracle Forms environment which is session/state oriented.
You can however achieve functionality similar to Enter Query / Execute Query through other means.
The easiest is to use the Forms with Report wizard. It creates 2 pages, the first one is a report and the other a Form. Clicking on the Report rows takes you to the Form page in Edit mode where as the the Create button takes you to the Form in Insert mode.
If you want to have the enter-query / execute query on a single page it will require significant effort and skills. Try it when you have acquired some more skills in Apex.
In APEX , like any other web application, you have to think in the web paradigm and not client-server. Even Forms 11g is essentially client-server like and is session oriented through the forms applet.

Calling APEX form with dynamic parameters from Oracle Apps 11.5.8

I have successfully managed to setup access to APEX forms from Oracle Apps 11.5.8 menus utilising Form Functions passing a number of hardcoded parameter values as outlined in the document, http://www.oracle.com/technology/products/database/application_express/pdf/Extend_Oracle_Applications_11i.pdf.
I am now trying to ZOOM from an Oracle Form passing values of form items (dynamic parameters) to an APEX form. I have so far not been able to do this.
I've also tried using;
web.show_document('http://derep.obup.co.uk:4657/pls/apex/f?p=100:1::::::p1_cust_account_id:'||name_in('ast_cu_act.account_id')||':', '_TOP');
but this prompts for a username/password again as this bypasses the APEX Launch process that is defined in my Form Function.
Is this possible in the parameters section of Form Functions? or elsewhere.

Hi Daan
We do havea couple of customers doing this, they have taken two approaches:
1. Install XMLP on a separate server entirely - kick off conc request to extract data and then use Java Messaging Service (JMS) to push the resulting XML to the external server where they are using AQ to set up jobs for the XMLP server to work through, generating and delivering the final documents.
2. Set XMLP up as a virtual printer - here the conc request again generates XML but this time the result is directed to a virtual printer namely XMLP. There is a perl or similar wrapper that gets called as the printer and accepts the data, template, output format and delivery destination as parameters.
Apologies for the 10,000 feet overview, hope it helps. Tim
