BUG: apex_item.textarea default values

ApEx Team....
I doubt this was intentional, but perhaps it was. I certainly won't discredit the idea.
In 4.0.1.00.03, I describe the APEX_ITEM package spec and find that the TEXTAREA function has two parameters, p_rows and p_cols, which have defaults of 40 and 4, respectively. I would venture to say that these defaults are likely reversed inadvertently. I used the defaults to create a textarea and found it a bit difficult to use in practice.
>
function textarea (
-- Generates an HTML input type of text. Basically a single hight form field.
-- Arguments:
-- p_idx = The form element name, e.g. 1 equals f01, 2 equals f02, etc.
-- Typically the p_idx argument is constant for a given column.
-- p_value = Text displayed in HTML textarea.
-- p_rows = Height of the textarea (HTML rows attribute)
-- p_cols = Width of text displayed on screen (HTML cols attribute)
-- p_attributes = Extra HTML arguments you wish to add
-- p_item_id = Will set the ID of the item to this value (id="..."). Must be unique! Try concatenating some string with rownum. Required for 508 compliance
-- p_item_label = Creates an invisible label for an item. Used for Section 508 Compliance. Class is hideMe508.
-- example(s):
-- select htmldb_item.textarea(1,ename) from emp
p_idx in number,
p_value in varchar2 default null,
p_rows in number default 40,
p_cols in number default 4,
p_attributes in varchar2 default null,
p_item_id in varchar2 default null,
p_item_label in varchar2 default null)
return varchar2
>
After setting these parameters explicitly, I got a textarea of my liking.
I looked through the 4.0.2 release notes and did not find this listed as something it addresses, so I thought I'd post something.
Shane.

Hi Shane,
thanks for letting us know. You are right, these defaults do not make sense. I have filed bug# 10376966.

Textarea default value disappears after a second in version 11, why?

I use default value in html form element, textarea.
It works fine in firefox 4.0 beta.
But not in firefox 11 and firefox 3, the default value disappears after a second just like a flash.

Perl adcfgclone.pl dbTechStack default values...?

Hi!
Our config: DB 10g2.0.2, APPS 11.5.10.2
When we run "perl adcfgclone.pl dbTechStack" then some default values are shown in screen:
Do you want to use a virtual hostname for the target node (y/n)
Target instance is a Real Application Cluster (RAC) instance (y/n)
*Target system utl_file accessible directories list [var/tmpprod]:*
Number of DATA_TOP's on the target system [6]:
...Where are those settings saved and retrieved in runtime? I'd like to change some default values to some new values (i.e. number of data tops to "7", after adding some luns)... Funny, but I couldn't find the source ... of that pattern.

I hope I'll not disobey some rules...however here it is:
The script adcfgclone.pl calls CloneContext.class. This java code is responsible for creating the Target
Context file. The default values for the prompts are read from CTXORIG.xml (a
copy of the Source context file). There are some exceptions to this, one of
them being the "number of DATA_TOPs". This default value derives from the
number of "s_dbhome" variables in
+$ORACLE_HOME/appsutil/clone/data/stage/addbhomsrc.xml. This file is generated+
on the Source system by adpreclone.pl, and copied to the Target system during
the copy phase.
As you have uploaded your addbhomsrc.xml and it is not working as specified above indicates you may be hitting a bug.
Your default value appears to equate to "number of "s_dbhome" variables in addbhomsrc.xml 1".+
+This matches an issue reported in Bug 5345502, where an additional variable+
+added for 10g was being counted in addition to the s_dbhome variables, making+
+the default number 1 more than the source. This was fixed for both 11i and R12+
+in :-+
+- CloneContext.java 115.204+
+- CloneContext.java 120.31+
+As the AutoConfig/RapidClone code is collected from the Applications Tier into+
+appsutil.zip, please check the following version on your Applications Tier:-+
+- $JAVA_TOP/oracle/apps/ad/context/CloneContext.class+
+If the version is < 115.204, then you need to apply the latest RapidClone patch:+
+6718351 : 11i RAPIDCLONE CONSOLIDATED FIXES JUL/2008+
+This will deliver CloneContext.java 115.223+
+Please also check the version(s) on your Database Tier:-+
+- $ORACLE_HOME/appsutil/java/oracle/apps/ad/context/CloneContext.class+
+There is also another version on your Database Tier which is copied by adpreclone.pl+
+into the Clone stage area, so we need to confirm that version:-+
+- $ORACLE_HOME/appsutil/clone/jlib/java/oracle/apps/ad/context/CloneContext.class+
+If the version on the Apps Tier is > 115.204 and does not match those on the Database Tier, or you had to apply the suggested patch 6718351, then you need+
+to recopy the AutoConfig/RapidClone code over to the RDBMS Tier.+
+Recreate appsutil.zip using this command on the Applications Tier:+
+- perl $AD_TOP/bin/admkappsutil.pl+
+Copy the created appsutil.zip to the RDBMS ORACLE_HOME and extract it using "unzip -o" to overwrite the existing+
+code.+
+Once you have the latest version, you will need to rerun the "preparation stages" on your Source system by rerunning adpreclone.pl, so the+
+new code is copied to the clone stage area.+
+You will also need to rerun adpreclone.pl on the Apps Tier.+
+Finally, recopy the instance files to your Target system, and when you configure the Target Database Tier, and are+
+prompted for the "number of DATA_TOPs", you should now see the number match+
+that on the Source system, or more specifically, match the number of "s_dbhome"+
+variables in+
+$ORACLE_HOME/appsutil/clone/data/stage/addbhomsrc.xml.+

Possible bug ? - Default value for select list

4.2.1
Hi, I have one page with a couple of reports. I have a time period filter on top. Its a select list with values 7 days, 3 months and 12 months. Default value is set to 3 (where return values of select list is 1,2,3 resp).
Now in page 1 which has this select list, :P1_SELECT it has a report which shows counts of number of items purchased. When the user clicks on the count(hyperlinked column), it takes the user to another page which runs the details of the items and also uses the Page 1 select. It works fine when I change the time period. However, if I dont change the time period in the select list when I first login, althought I have set the default value to 3, the interactive report on page shows no data found, because the select list default value I guess it does not recognize.
Is this a bug?
Thanks,
Sunil

Default values is only populated on the clien side and NOT in the session.

Content Organizer bug - PDF files does not get routed correctly if autodeclaration is on and library level default values are set

It looks like whenever one specifies Column default values at a library level then the content organizer routing goes a bit awry SPECIFICALLY FOR NON OFFICE FILES [e.g. PDF] . Below are the observations and issues
1. Column level default value set on a record library with auto declaration of records turned on. The content organizer routes the document to the library but also keeps a copy of the document in the drop off library. It does not remove it from the drop
off library. The instant we clear the default value settings at the library level of the target library the content organizer works as expected again.
2. If default value settings are specified on a column in the target library then the PDF file gets routed to the document library but all the metadata is blanked out. The copy of the file that remains in the drop off library has all the correct metadata but
the target library has blanked out metadata.
Are the 2 observations described above by design or are they bugs? If so is there any documentation that is available that proves this because this does not make logical sense and proving this to a client in the absence of any documentation is a challenge.
The problem goes away if we shift the default value to the site columns directly at the site collection level. It's just the library level defaults that the pdf files do not seem to agree with

Hi Lisa,
Thanks for responding. This can be replicated in any environment but is only replicable for a specific combination of content organizer settings . The combination of settings I am referring to can be seen in the screenshot below. If you turn off redirect
users to the drop off library for direct uploads to libraries and if you turn on sharepoint versioning then you should be able to replicate the issue. Also we are using managed metadata site columns. I simplified this use case to a custom content content type
with just 2 custom managed metadata columns and can still replicate the issue in several environments. Also note the issue does not occur if the default values are set at the site or site collection level. It only occurs if you set the column value default
at a library level. I was able to replicate this on a completely vanilla Enterprise records site collection freshly created just to test this. Also note that the issue is not that the file does not reach the destination library. The issue is the
document does not get removed from the drop off library after it is transfered to the destination library which technically should have gotten removed.

Apex_item select list to be displayed with multiple default values

I am using APEX 4.2.
For one of our requirements , we are displaying a report which uses "apex_item.select_list_from_query" multiselect field.
The above function accepts a parameter, 'p_value' using which we can specify the default value to be highlighted.
Is there any way to highlight multiple values on the select list by default, when the page is loaded, based on a sql output.
Sample Scenario:
Say colour is a multiselect field. Full list of values available : R, B, G, Y, O
On day1, for record1 i am choosing R and B. which I am saving in the backend when the page is submitted.
On day2 : I login again to see the report. When the report is loaded, I should see the values 'R' and 'B' highlighted or in a different font format , differentiated from the rest.
Thanks in advance for your replies.
Regards,
Raasi

May be populate the hidden item with default value as colon delimited string and on page load use some JavaScript to read that string and set/highlight the select list.
It would be easy if you can replicate the issue on apex.oracle.com

Vivado 2015.1 Bug Report: Adding Required Port without Default Value in Custom Interface Definition

When adding a port using the Custom Interface Definition window and not defining a Default Value, the attached error message appears. Not only are the html tags visible, but this error should not be thrown in the first place if both Master/Slave Presense is set to "required". As it is, a port can only be added if a Default Value is given, but can be removed later from the ports table.

yes,I have successfully install petalinux2015.2,but,the issue still be the same as before,the axi 16550 is not working,when I run echo 123 > /dev/ttyS1,my ttyPS0 stop working and axi com keeping null output...
then,I try petalinux2014.4+petalinux2014.4,the difference is the ttyPS0 still alive but axi-com still null...
I found that pl.dtsi file is quite different between the three mode:
M1,petalinux2014.4+vivado2015.1
M2,petalinux2015.2+vivado2015.1
M3,petalinux2014.4+vivado2014.4
most confuse for me is the interrupt ID,
in vivado I connect the axi intterrupt to ID 62 but I get different auto generate dts file
M1:nothing about interrupt and i add manuually in system-top.file
M2:vivado ID is 61 but dts "interrupts = <0 30 4>"
M3:vivado ID is 62 but dts "interrupts = <0 31 4>"
does petalinux auto detect the vivado interrupt connection and ID and write to dts file right or User have to verify and rewrite in ststem-top.dts?
working hard for the issue and hope for a axi demo including petalinux + vivado ,help please

Thank you much for your response.
I tried that and it did work. But my requirement is to have a user input the date. The basic idea is if the user decides on a predefined time range like Day Shift Today or Yesterday and so on... then the report would automatically calculate the values based on predefined date time values. On the other hand, if the intent is to run the report for an arbitrary period then the user supplies the date and time limits.
What I am trying to achieve is have the same parameter available for user input , but when the User decides he wants Predefined then the "textbox" populates with date and time as per his choice of predefind range.
I understand that by this the user can still overwrite the date and time on the text box, but the report will run the predefined values as long as he has the @PredefinedDateSelection Set to true.
Is there a way I can impement this?
Once again I thank you and appreciate your input.

Custom CAPI service - default value of varchar2 parameter

I have a Custom CAPI Service function. That function has a varchar2 parameter (argument) and I wish to set a default value NULL for that parameter.
I set Default=null, and when I generate CAPI package, my function in that package looks like this (notice the quotation marks around null):
function cs_cjn_prod_cijena
( p_nacin_prodaje in varchar2 default 'null'
return number
is ...
And it should look like this:
function cs_cjn_prod_cijena
( p_nacin_prodaje in varchar2 default null
return number
is ...
I tried setting Default Value Type to Literal, Database Function Call, Client Function Call, but it's always the same thing.
If that parameter was number or date it would generate ok.
It seems like the bug in "Generate CAPI Definition" Headstart Utility.
I know that I can make my function's code to treat the string 'null' as a null default value, but I'd like to have a "real" null as a default value.
Does anybody have a solution for this?
Thanks!
Dalibor

Marcel,
Thank you for your answer, but it didn't help. I have already tried using Database Function Call. This time I tried deleting the CAPI package from repository before generating it again, like you suggested, but it didn't help.
I still get: p_nacin_prodaje in varchar2 default 'null'
Which version of Create CAPI Definition utility do you have?
My version is: HSU_CAPI, Revision: 6.5.2.0 ("Help/About This Utility" in Headstart Utilities application)
Thanks again,
Dalibor

Report Builder 2.0 loses parameter Null default value when deployed

When a parameter is set to a default value of (Null) and the report is saved to the sever, the default is lost when the report is re-opened in RB2. This problem doesn't seem to occur in BIDS. I've tried to use an expression to set the value to System.DBNull but this can no longer be done.
Any ideas for a work-around?
Is there a bug report open for this? I couldn't find an open bug on the Connections site and there's an issue on that site right now when submitting feedback.Paul Turley [Hitachi Consulting]
SQLServerBIBlog.com

Hi All,
I just had an almost identical issue using report builder 3.0 so I don't believe it is fixed. I had 4 parameters set to default to (Null) and I added a new one with identical settings but it would continually come up blank and not check the null box automatically
when going into my sub report.
To make matters worse I experimented changing one of the old parameters and it then started exhibiting the same behaviour. Using Luke's post above solved the issue (though it was Manage in my version not Administrate).
Using System.DBNull.Value resulted in it being treated as a literal string "System.DBNull.Value" and putting that in the filter for me.
Hope it helps.

ORA-01400 - not null column with default value and item with authorization

I've searched - I would think someone has run into this. APEX 3.0.0.00.20 - I've created a simple form on a table. One of the column is a not null column with a default value. I have a select list on that item, but it has security on it - authorization scheme. So, it checks the user and if that user isn't of the right role, it will not even display that item. However, APEX appears to still send in the column in its sql! So, the default value is useless, it sends in null each time. Even if I set the default at the Item level, I get null. Argg. That's got to be a bug...
In debug, I do not see the item listed at all. It's not used. That's fine - but why is it trying to insert the value? I would think it would leave it off??? I think because the item is associated with a database column. But, getting around this is ugly. Having to create a hidden item for each one, and then check to see if I need to take the list value... horrible. Any way to get around this???

I should add - I guess I can always put my own custom process in to replace the DML. Just seems like a simple thing - if the value doesn't appear on the debug, isn't set with any default value... don't include it in the DML.

Passing Database Constant as a default value to EBS TCA API??

My synch BPEL process calls EBS TCA (Trading Community Architecture) APIs via Apps Adapter to create and update Organizations (Parties) and Customers (Accounts) accordingly. TCA provides two types of APIs to do the same job - one uses record types and tables as parameters, while the other uses object types as parameters and is called Business Object(BO) API. I am using BO for my solution.
One of the features of the Update API (hz_org_cust_bo_pub.*update*orgcust_bo) is you can pass a database constant (FND_API.G_MISS_CHAR) as a parameter value in order to nullify an existing value. Ex: AddressLine2 for a customer address has now changed and does not exists anymore. In order to update and existing value to NULL, you are required to pass one of the following constants as a parameter value.
Following is a formal description of these optional parameter values from the TCA Reference document.....
Optional IN parameters do not have default values. An attribute value that is not
passed in is assumed to have a default of null for a Create API. For an Update API, if a
particular attribute value is not passed into the API, then the database retains the
existing value. In order to set a database value to null, the calling program must
explicitly set the attribute value to one of the following constants, based on the data
type of the attribute.
+• FND_API.G_MISS_NUM for NUMBER type. (or FND_API.G_NULL_NUM)+
+• FND_API.G_MISS_CHAR for VARCHAR2 type. (or FND_API.G_NULL_CHAR)+
+• FND_API.G_MISS_DATE for DATE type. (or FND_API.G_NULL_DATE)+
ISSUE:
I am unable to pass and have the value FND_API.G_NULL_CHAR be treated as a constant by the API. When this value is passed by the BPEL process to the Apps Adapter (API) it gets passed as a string literal, as such, does not get treated as a database constant by the API. Also, on creating the apps adapter for this particular API (TCA BO) a wrapper program is NOT created. So, I can't modify the wrapper (as it does not exist) to pass this FND_API constant. The only option I can currently think of is to write my own custom PL/SQL package that calls the standard API and in turn have the custom package be called by the apps adapter. But, I am hoping this is not the only option, it takes away several benefits.
Any thoughts will be greatly appreciated.
ilyas

I think that may be your only option. I haven't implemented this using the Apps Adapter but in order to get this functionality you need to have implmented the security architecture where you login as an Apps User, not APPS.
I would raise a SR for this as this may be a bug.
cheers

Error while using APEX_ITEM.TEXTAREA()

Hello All
I am using Apex, quite a few days now, but had a problem with APEX_ITEM.TEXTAREA. When I input more than 2000 characters in my Textarea it is giving an error of 404 as follows:
Not found
The requested URL /apex/wwv_flow.accept was not found on this server
I really didn't get where I am making a mistake. This text area input is a feedback which I am using in a Update statement inside a process after submit.
Anything else if you needed then please let me know...

Hello All,
I am still hunting for the solution, but this time I will be more specific about the error, As I mentioned earlier I am getting an error of "404 Not Found" whenever I try to insert 2000 characters in an APEX_ITEM.TEXTAREA() which I am passing to an UPDATE statement using APEX_APPLICATION.G_Fxx(i).
Now to get the details of this "404 Not Found" error I set the "error-style" attribute of APEX DAD to a value "DebugStyle" using DBMS_EPG.SET_DAD_ATTRIBUTE() procedure (for more information you can refer to PLSQL Package and Types 11g b28419.pdf). By setting this attribute I got the detailed error as:

How to default value in collection after intial collection field entered

Hi there,
Am working on gettting to know collections but not really had much to do with them so far.
I have a multi row data entry screen that works great using a collection. Now the boss has decided that the new records require a default value that the users can overwrite if required.
The value i need to default is the second field in the collection but i only want to populate the value after the first field in the collection has been entered.
Could anyone talk me through how i do this please or point me to any relevant documents.
Cheers
Lisa

Hi Lisa,
If you want to default value only after user enters data in another row column, you ll have to write a javascript code that executes after the column is entered
If you have jQuery(already included in apex 4.0) it would make the task of accessing that other column easy.
Otherwise its much more harder work to get I can think of setting the ID's using the pitem_id_* while rendering the editable fields(set it for both the columns..say as COL1_ROWNUM , COL2_ROWNUM ) using APEX_ITEM. Then add an onblur event(using the html attributes parameter of APEX_ITEM api) call a JS function with the rownumber(to identify the row). You can then write the logic for default value inside the function and set the corresponding column with the value.
If you can update about your version and/or if you use any JS libraries, it would be easier to help you any further.
