Apex 4.2 200 Page Items limit

Hi,
I have a master-detail form which was getting close to the 100 items per page limit in Apex 4.0 which I then scaled back and got to work properly. I had thought that I could start adding more columns to the detail part of the form since 4.2 was supposed to have increased that limit. I am finding that this does not seem to be true at least in the case of this particular form. I tried increasing and started getting 404 errors when trying to save data--same symptom I had had with 4.0. I am back nearly to the same # of columns I started with--and nowhere near the 200 limit. Columns are month by month projection data that I had hoped to extend with the increased page item limit.
Am I missing something required to take advantage of larger page items limit? Do I need to use one of the new templates?
Any pointers would be appreciated!!
Pat

Hi Pat,
changing the compatibility mode will have no affect in your case. First I would check the real reason for the HTTP 404 error. See http://www.inside-oracle-apex.com/oracle-apex-got-404-not-found-2/
I assume it's not the page item limit you are hitting, instead I think you are running into the 2,000 parameter limit of mod_plsql, because your tabular form has too many rows/columns. See mod_plsql:/pls/apex/wwv_flow.accept HTTP-400 too many arguments passed

Page Item Limit?

I have a vague memory of reading this somewhere, but can't find it in the forum.
Is there a limitation on the number of items you can have on a page? I think I may have hit it.
Thanks, Tony

Thanks Scott,
Would page zero items be included?
It does appear that I have hit the limit. The page has well over 50 items on it, not including page zero items. Now, when I add a new field and try to save the page I get an 'unable to load page' in I.E. and get a 'cannot find wwv.flow.accept' error in Firefox. I thought it was something about the field type, etc. but after hours of debugging it simply seems that I have hit an item per page limit.

Page item display 32767 characters (via computation)

Hello everyone,
Running APEX 3.2.1.00.11
I am trying to generate values for a page item using a PL/SQL function body. It parses and concatenates many rows of our databases. In one case I need to return some generated javascript code to pre-load a auto-suggest class. In the other case, I need to concatenate a variable number of comment postings for a given article "to create a threaded blog view" (the number of comments could get quite large).
My problem is that APEX is maxing out at 32767 characters. When I defined my function with a VARCHAR2(32767) I got a buffer too small error. When I tried to run it using a CLOB I got a "ORA-06502: PL/SQL: numeric or value error string". I'm assuming this happens when it tries to exit the PL/SQL function and return control back to APEX (some type of CLOB -> VARCHAR2 conversion - but once again i'm just guessing).
I tried to verify the code works fine by running it in sql developer. When using DBMS.OUTPUT.PUT_LINE I got the same ORA-06502 error. When I replaced the return string with a "function completed" message instead, it ran fine and printed out the success message.
To validate it wasn't the contents of the string, I changed the function to put a DBMS.OUTPUT.PUT_LINE on each iteration through the result sets that builds the large concatenated string. Every line printed without issue and no errors were generated...
So, my question is...how can I generate text > 32k in size and display it to the user through APEX?
Please don't respond and say that I shouldn't be loading that much into a webpage initially and that I should be using AJAX to search through values and load them on the fly. That could work for the select list (if I can get past APEX's very particular URL parsing system) but it is not suitable for the "blog comments" functionality.
Thanksss!!

I honestly don't know enough about how APEX generates it's page items and the overall page to be able to answer your question. All that I can tell you is that its a simple "display only" page item that has a before header "Computation" on it powered by a PL/SQL function body.Sorry, I missed the "page item" and focused on the "PL/SQL". In that case you've hit a hard limit in APEX. Page items, report rows and various other things have a maximum output size of 32K.
I could do multiple page items each limited to 8k as you suggested and strategically concatenate them behind the scenes too - however this is extremely ugly. I need to consider how other people will be able to work with this code in the future.Absolutely—I really wasn't suggesting separate items as I was talking about buffering output from <tt>htp</tt> methods.
For handling large items, see the Save Large Value demo app. As you can see, this is not "out of the box".
For display-only purposes, APEX reports or dynamic PL/SQL regions are a better fit for the use cases you describe than page items.

Page items not getting set upon login in APEX 4.0.2

We just upgraded our APEX in development from 4.0.1 to 4.0.2.00.07. While testing found that in APEX developer, unless we press one of the buttons (Debug/View Debus/Show Edit Links) in the tool bar on the login page, the application/page items are not getting set to display the conditional items (page regions/buttons/Tabs etc,.) Could this be some setting within APEX Developer?
But the display is fine when the application is run directly in a browser, as an end user.
Is anybody else having this issue? We are holding off our production upgrade because of this issue.
Any help is appreciated.
Thanks
Radhika

Hi,
Could you please explain what you mean by
Running 4.0.2 version...need to know how to remove the pop-up login and go straight to welcome/splash page?Do you mean application builder or your application login page ?
If you mean application builder, you can not remove login page. You need always login to builder.
If you mean your own application then change authentication scheme

How do you populate a page item in apex with a value read from excel

Dear All
I am working on application where I am uploading a csv file in oracle apex. I then need to access a value in Cell B2 of the csv file and populate a page item called
:P2100_AUTHORISATION_ID with this value. Many of the examples I have found upload the data using v_data-array into a table but I don't need to do that I just need to get the value from the csv file and then display additional information about the file allowing the user to either or continue or cancel the request to upload. I am running into a small problem that I can't explain and wondered if anyone had any ideas.
Here is the code I am using to try and populate and item called :P2100_AUTHORISATION_ID but when I poulate the item the value is always 0. But if I replace the line :P2100_AUTHORISATION_ID:= v_data_array(2) with a raise_application_error(-20001,v_data_array(2)); The correct value is displayed in the eror. Any Help would be appreciate and I apologise in advance if this akes no sense at all:-)

Hi Joel
Continuing on from my last question, there was something else I want to ask if you dont mind.
Now that I have the v_data_array(2) value in a page item I would like to use as an input value to a procedure to return some information I need displayed on the page. To do this I need to convert it to a number but when I try to so this I get the following error
ORA-06502: PL/SQL: numeric or value error: character to number conversion error
When I use the wwv_flow.debug that you told me about it is outputting a value '4851 ' so it look like there may be some sort of asii character causing a problem. I have tried using trim(v_data_array(2)) and ascii(v_data_array(2)) but nothing seems to work.
Would you know how to convert a v_data_array value to a number? At the moment I am attemting to do it withiin the same code I attached in my earlier post but I have replaced the assignment of :P2100_AUTHORISATION_ID with the code below where P_BL_WD_DATA_ENTRY.getauthid is the procedure returning the values I need.
:P2100_AUTHORISATION_ID:= P_BL_WD_DATA_ENTRY.getauthid(to_number(v_data_array(2)));

Reset data picker page item by selection page item in Apex

Hi,
Need to create a report based on date ranges and for this created a interactive report and two page item datepicker fields P15_fromdate and p15_todate. Report works fine with this criteria.But user wants one more field quarter(P15_quarter), When they select the quarter the range values has to get reset and as to get applied to report.
Issue here is unable to find a way to set the page range item values based on the quarter field selection
Need help how to reset the page item fields.
Thanks in advance.
Thanks,
Sandeep

Ligon,
You're right to think this is pretty laborious stuff. A co-worker wanted to do the same, to make sure users didn't lose a change when clicking Cancel. I suggested he look at calculating the query checksum before and after, which he tried. But it got very cumbersome very fast and he ended up dropping the idea. He's fairly new with Apex, but he's also a quick study, so it's not like he's a novice coder.
I don't have his implementation details anymore to even share with you.
Sorry I couldn't be more help.
Good luck,
Stew

Page item rendering location relative to report? (APEX 2.2.0)

Hi all,
What controls where the page items in a region containing a report will be rendered? I have two regions that (I thought) I set up identically, but one has the items above the report and the other below.
The only difference between them is that the one with the items above is on a non-zero page, whereas the one with the items below is on page zero.
(I cannot post my app to a public area as an example.)
Am I missing something?
Thanks!
Don

Hi all,
I apologize if I was vague or confusing. It's been a long Friday and it is continuing to be a long Friday = ) Louis-Guillaume, I tried changing one of the regions, and something very odd happened! So here's exactly what I do:
I create a region in page 0, "My Page Zero Region". It is an SQL report region. I then add "Item One" and "Item Two" to that region. The items are in the same region as the report table. I put it at the "Page Template Body (3)" display point. I then get this:
My Page Zero Region
Item One : [             ] (this is an item.)
Item Two : [             ] (this is an item.)
|            | the table |         |
|            |            |         |
|            |            |         |
---------------------------------The items are displayed above the table. I then switch the display point to "Page Template Body (2)". The region is then rendered differently.
My Page Zero Region
|            | the table |         |
|            |            |         |
|            |            |         |
Item One : [             ] (this is an item.)
Item Two : [             ] (this is an item.)It seems that APEX treats the entire region differently depending on which display point it is in. Is that the correct functionality, or should I investigate further?

Session State Protectio Violoation in Apex 4.2 Page Items

I'm testing my Apps that I upgraded from 3.2 to 4.2 and getting the message below and haven't been able to understand why.
Error Session state protection violation: This may be caused by manual alteration of protected page item P2_PAY_NO. If you are unsure what caused this error, please contact the application administrator for assistance
How the Page works.
1. Before Region Process runs that pre-populates some of my Text Items.
2. The user then has the ablibity to select from a select list item that will re-populate the items populated during the Before reqion based on the date selected.
I do this by calling the code below with an "onchange="javascript:date_populate(this);" on the HTML Form Elements Attributes.
{var myString = $x(pThis).value;
var mySplitResult = myString.split("|");
$x('P2_START_DATE').value = mySplitResult[0];
$x('P2_PAY_YEAR').value = mySplitResult[1];
$x('P2_PAY_NO').value = mySplitResult[2];
$x('P2_PICT_CODE').value = mySplitResult[3];
$x('P2_END_DATE').value = mySplitResult[4];}
3. When I submit the page I get the Session State Violation.
All Items have "Session State Proection" set to "Unrestricted"
Session State Protection is "Disabled" for the application.

Need help on Oracle APEX- Retaining Page items of one Session in another

Hi,
I am creating an apex application in which there exist two pages. Out of 2 pages, I need to provide authentication on one page and no authentication on the other one.
When I access the first page by public, I must pass some page items to the second page. Since, I have aunthentication on page 2, there will be a new session created and I could not retain the page items that are passed from Page 1 to Page2.
Please help me in retaining the page item values of Page1 in Page2.
Thanks for your help.

Hi Andy,
I have passed the values from page 2 to page 3. Due to Authentication on Page 3, the passed values are cleared and a new session created.
Is there a way to retain the item values using Application items or Application computations?
Please help.
Thanks,
Hanu.

Capture External HTTP POST Into APEX Page Item

We have an APEX page that needs to capture into page items two form fields posted from an external application: PARAM1 and PARAM2.
Unfortunately the external application cannot be changed and we tried to add the two posted fields as APEX page items with the same name, yet we get back an exception:
f: SIGNATURE (parameter names) MISMATCH
VARIABLES IN FORM NOT IN PROCEDURE: PARAM1,PARAM2
NON-DEFAULT VARIABLES IN PROCEDURE NOT IN FORM:
Any ideas on how this can be done?
Thank you.

You could do this with an intermediate non Apex page (.html for example) that receives the params and the calls apex.
Or even better with a procedure that gets called by the external post:
procedure myForm (param1 in varchar2, param2 in varchar2)
is
begin
f(p=>'app:1:0::::P1_PARAM1,P1_PARAM2:' || param1 || ',' || param2);
end;
Then you grant execute on myForm to apex_public_user
change app to your app number or alias and use the right page or item name. But you'll want the parameters to match the names posted.
hope this helps
The new myForm procedure can be called with the same path as the f procedure in APEX. So if you're APEX URL is something like:
https://apex.oracle.com/pls/apex/f?p=...
Then you can use:
https://apex.oracle.com/pls/apex/myForm
And with parameters:
https://apex.oracle.com/pls/apex/myForm?param1=value1&param2=value2
Thanks

Apex: Validation on two dependent page items

Apex 4.2
I have a form with two separate regions that each have text fields / select list on them. I need to validate one field againt another.
**Region 1
- P10_REQUESTOR
- Select List
- LOV defenition:
SELECT first_name
FROM PERSONS
ORDER BY firs_name
I.e. you can select a first name from the select list
**Region 2
- P11_NAME
- Text Field
A regular text field to type in the first name of a person
**Logic:
When a user navigates to this page, they can either pick a first name from the select list OR if the name is not in the list, they can type in the name in the P11_NAME text field. However, they can not do both. I am having a little trouble writing a validation script to capture these cases.
Case 1: P10_REQUESTOR is null & P11_NAME is not null
Case 2: P10_REQUESTOR is not null & P11_NAME is null
If both items are null then an error message needs to appear stating that one or the other must be filled out
If both items are not null then an error message needs to appear stating that you can only fill out one or the other
I have pseudo coded it and understand the logic but am having trouble on knowing which options to choose when creating the validation. I was thinking its somewhere along the lines of a PL/SQL function with a few IF statments in it.
Any help would be greatly appreciated. Thanks in advance.

Hi NewApexCoder,
your problem is solved in two ways,if i understand you correctly.
You can do a simple javascript on the NAME i.e you can enable and disable this item_type by putting this snippet into the Form element attributes
To take care of Case1
OnBlur = "javascript: if (this.value != '') { document.getElementById('P11_NAME').value = 0; document.getElementById( ' P11_NAME').disabled = true; } else {document.getElementById ( 'P11_NAME').disabled = false;}"
OR
2. In the Select List Page Item ,By adding an extra Display Extra Values = YES
Display Null Value = YES
Null Display Value = '%' Null Return Value = -1
After which you can set up a validation for an item.
Validations> Page>P10_REQUESTOR> Then choosing a PLSQL Function Returning Boolean
Validation Code
begin
if P10_REQUESTOR = -1 then
return true;
else
return false;
end;
2.Error Message
"A Request must be selected"
To take care of case 2
Thanks

Reports - "Derive from Page Item" Missing in APEX 3.0.1?

I installed a patch 3.0.1.
I can't find on the list of formats in report queries option:
"Derive from Page Item"
But, in help window for the list of formats I can read:
"The format attribute specifies the download format for the report query.
Report queries can be downloaded as PDF documents, Word documents (RTF
based), Excel Spreadsheets
(HTML based) or as HTML files.
To determine the download format at runtime of the application, choose
"Derive from Page Item"."
Where is "Derive from Page Item" option?
Best Regards
Daniel Kozlowski

Option "Derive from page Item" is still available in 2 places:
1. "Shared Components -> Report Queries -> Create Report Query" on last
"Create Shared Query" window.
I can choose it from "Output Format" list.
2. In report properties on "Print Attributes" tab.
I can also choose this option, from "Output Format" list.
Of course, above options still doesn't work correctly.

Page Item with Date format DD-MON-RR - APEX 32

Hello,
I am passing date parameter but somehow it is not formatting date properly on calendars.
For e.g.
Below is my calendar query
select distinct count(*) knt, initcap(username) username, to_date(to_char(trunc(timestamp),'DD-MON-RR'),'DD-MON-RR') ts from xrx_master_records
group by initcap(username), trunc(timestamp)In above query TS is the date column that results in DD-MON-RR format.
Then I format column on calendar tab as shown below, here is how I am constructing the link.
But the issue is - #TS# field shows complete date with time stamp for page item P40_DAILY_DATE. i.e. instead of 21-JUL-10, it shows 21-JUL-2010 12:00:00 AM. That means, it is ignoring calendar query and reads straight from database.
How can I make sure that P40_DAILY_DATE item receives date in DD-MON-RR format?
Then, I plan to use P40_DAILY_DATE to connect with the report region by comparing timestamp column from same table with P40_DAILY_DATE.
Please advice.
Thanks,
R

Hi K,
One way to achieve a result similar to what you are looking for is to use a combination of pop-up menu for the initial choice and a slider or stepper to make the second choice. The example below uses a slider. The formula would be the same for a stepper cell in column B of Main.
Column A contains a series of pop-up menu cells with for choices: -- (no choice yet made), Red, Blue and Green.
Column B contains a series of slider cells, each with the same values: Minimum: 0, Maximum: 3, Interval: 1.
Each cell in Column C contains the formula below, which uses OFFSET, MATCH and the value set by the slider to retrieve the correct value from the Lookup table.
Main::C2, and filled down: =IF(A="--","--",OFFSET(Lookup :: $A$1,B,MATCH(A,Lookup :: $1:$1,0)-1,1))
Results for various combinations of the pop-up and slider cells are shown.
Regards,
Barry
