Tabular forms, referencing current row and using checkboxes

I've searched through the whole forum and read over 50 threads on referencing other columns in a tabular form only to find this impossible. Many of these threads were outdated so I would like to ask it again.
Can I use references between columns of tabular forms? So that value of one column equals the other's. (select a, b from c where d=othercolumn)
How can I get a workaround for lack of checkboxes in dynamically created tabular forms? (Standard tabular forms come with checkboxes for deleting multiple rows, can they be used in the same way but without writing manual reports?)
Please do not send me to

I am looking for strictly dynamic, apex-like solution. Thanks in advance.

That supposed to be a query for LOV, should have mentioned that probably. By dynamically created tabular form I mean the wizard-created form which transforms query results into a form on the fly. I consider the HTMLDB_ITEM-style the manual way. After all, I'll probably stick to the manual method because I am creating this form on a view with INSTEAD OF triggers so the processing still needs to be done separately.
The question I asked referred to the internals of tabular forms' processing, behind the screen wizards there has to be some loop based on the query, I just wanted to reference other columns on the current iteration. (wwv.g_f01(0) ?...)

Custom Popup on a Tabular Form for Multi Row Operation

I am trying to implement a custom popup on a tabular form that I can pass a value typed in to a text item like âNameâ to the popup so it can filter a list of names on what was already typed in.
Once a selection is made I need to have the selected name passed back to the text item.
This is easily done when not using a Tabular Form. Any ideas would be great?

Can someone please help me with this?

Need to Set Current Row when Using Built-in Data Control Delete Operation?

I have an af:table bound to a ViewObject (VO) collection (no Entity Object) - within each row, I include a column that contains a 'Remove' command button so the user can remove the row. I add the command button by dragging/dropping the built-in delete operation from the VO on the Data Control Palette. When I use this as is (no changes), the Remove button always deletes the first row in the collection, not the selected row. Do I need to add code to set the current row, and if so can someone please provide an example and specify where I need to add? thanks.
------ .jspx af:table with command button to remove each row ------
<af:table value="#{bindings.ListView1.collectionModel}" var="row"
rows="#{bindings.ListView1.rangeSize}"
first="#{bindings.ListView1.rangeStart}"
// note: I don't have any code added for selectedRow or makeCurrent - assuming this is built-in?
selectionState="#{bindings.ListView1.collectionModel.selectedRow}"
selectionListener="#{bindings.ListView1.collectionModel.makeCurrent}">
<af:column>
<af:commandButton actionListener="#{bindings.Delete.execute}"
text="Remove"
disabled="#{!bindings.Delete.enabled}"/>
</af:column>
---------- corresponding pagedef file ------------
<bindings>.....
<action id="Delete" IterBinding="ListView1Iterator"
InstanceName="SrchDataControl.ListView1"
DataControl="SrchDataControl" RequiresUpdateModel="false"
Action="30"/>
</bindings>
Note: I also tried solution posted on following thread, but again, only first row is deleted, not the selected row?: Delete and Commit
Message was edited by:
javaX

I just want to delete (or remove) it from the VO. Data for this VO is not on the database.
The function is doing what I want it to do (delete from the VO), its just always deleting the first row, versus the selected row. I select the command button next on a column next to an item further down in the list and it deletes the first row. The problem is setting the selected row to be removed - I thought setting the current row would be taken care of by the SelectListener?
selectionState="#{bindings.MyIspListView1.collectionModel.selectedRow}"
selectionListener="#{bindings.MyIspListView1.collectionModel.makeCurrent}"

How can I move my old iPhoto library into a Referenced Library format and use that as my default?

Hi, I have been using iPhoto for photo management where all the jpegs have been living, in organized events by date and subject for some time. I recently upgraded to aperture and am using the same iPhoto library. The issue I have is that I use Carbonite for my cloud back up and I am able to look at the pictures I have on my PC with the same folder organization I have them on my PC hard drive. This is apparently not possible for iPhoto library. The only way to access a picture on the iPhoto library in the cloud is to go through the master and hope you can find the specific picture since they are not organized in a comprehensible manner (like events or folders) in there.
So the only solution I can think of is to move the current iPhoto library to a referenced image library and use that as my default library from now on. This way I get cloud access and the events will hopefully turn into folders with dates and subjects that I can continue to keep organized to satisfy my OCD tendencies.
So the question I have is that:
1. How can I make a reference Library for Aperture/iPhoto?
2. How do I move the current library to the Referenced Library in an Organized manner? My wish list would be a series of folders labeled with the date and the subject, like I have in my iPhoto library right now.
3. If there is any alternative, your suggestions and recommendations would be much appreciated.
My computer: Mac Mini (Mid 2012), Lion, 16GB RAM.
Thank you kindly,

Or is there a way to go through aperture to make a new reference library that I can move the masters into later?
you do not move the masters into a references library - you turn your current library into a referenced library. As Terence Devlin said:
File -> Relocate Masters
What you should set up:
Select a folder, where you want to store your referenced files - probably on an external drive.
Decide on a hierarchical folder structure inside this folder - that is completely up to you.
Select a project from your library and use the command "File -> Relocate Masters/Originals" to move the original image files to the folder where you want to go them to. Only take care not to send two projects to the same folder.
Alternatively, if you do not care about the folder structure Aperture will use, select all images at once from the "Photos" view and let Aperture decide how to assing the folders - in the "Relocate Originals" dialoge you can specify a subfolder format.

Get current row and column in JEditorPane

Hi,
I have a JEditorPane and I want to show the current row and column according to the caret position
can anyone please assist ?
Thanks,
Dekel

JEditorPane was designed to display HTML which may not have a great concept of row column once you start adding tables and other fancy stuff. If you only have text data then I would use a JTextArea or JTextPane, they are easier to work with.

Web Form :Number of rows and columns

Hi All,
I have a web form with many rows and columns . Is it possible for a user to view only a limited rows in the form ? Not using Adhoc/Analyze option . since there are formula rows which wont appear in Analyze grid.
The user want to see only 5 to 10 random rows in the form ? How to do this ?
Please help.

I remember an option in 11.1 which allows users to dynamically add rows and I cannot find that in 11.1.2.2
I think the user will have to always update the user variable to what he want to see.

ADF multiple row selection using checkbox

One of the basic feature missing in ADF 11g is multiple row selection using checkbox (ADF supports multiple row selection by CTRL+CLICK) and business users doesn't like the idea of CTRL+CLICK especially when the volume of click is more. Our requirement is to show the records as selected, on click of checkbox. We implemented multiple row selection by giving a checkbox and on submission, iterate all the rows and filter only selected rows for further processing. The approach works fine,but it is very slow when the volume of data is more, say 10 thousand rows. For 4 thousand records, iterating everything takes more than 200 secs !
Had the multiple row selection been the ADF standard way using CTRL+CLICK, and retrieving the selected rows using method theTable.getSelectedRowKeys() works much faster (completes in millisecs for 4 thousand records). Somehow ADF fetches the selected records much faster this way. Our requirement is on click of the checkbox, the ADF should select the records ( the same way it is doing CTRL+CLICK) and all such selected rows should be retrievable using the ADF method theTable.getSelectedRowKeys()
Is there any way it can be done?
Regards,
Antony.

Hi All,
We have implemented the select and select all using check-box and it is working fine. Issue here is the performance is too slow
Assume SelectValue is the VO coulmn for the checkbox to select the values. To filter out the selected rows, we use the following line
Row[] pidRows = pidView.getFilteredRows("SelectValue", Boolean.TRUE);
it is very taking more than 2 minutes if the total number of rows are *4 thousands* and only if 2 rows are selected.
Whereas with the CTRL+CLICK standard approach, ADF has a built in API theTable.getSelectedRowKeys(); to get only the selected rows, and the built in API takes only few milliseconds to get the selected rows. Users are not agreeing to the CTRL+CLICK approach as it is not user friendly. Suggest if there is a way to make the select box to make it work the same way as CTRL+CLICK.
code snippet to do the standard way :
RowKeySet sk = theTable.getSelectedRowKeys();
_logger.info("row count of select "+sk.getSize());;+
Iterator selection =sk.iterator();
EmpVORowImpl empRow = null;
+while (selection.hasNext()) {+
Object rowKey = selection.next();
theTable.setRowKey(rowKey);
rowdata = (JUCtrlHierNodeBinding)theTable.getRowData();
empRow = (EmpVORowImpl)rowdata.getRow();
_logger.info("Emp # "+empRow.getEmpno() +" Emp Name : "+empRow.getEname() +" Is selected ? "+empRow.getisChecked());+
+}+

How to Select the Current Row When Using af:iterator?

Hello all,
I encounter the following problem when using af:iterator to display data from
a View Object:
When trying to display the content of a row via a popup, only the first row is
returned no matter which row is selected. So a selection of the current row
should exist or some other method which should allow the access to the
current row.
The af:table has a selectionListener attribute which permit to achieve this.
Does anyone know about some similar attribute or some method for
selecting the current row when the af:iterator is used?
Thank you,
Mirela

I would be interested in the answer to this basic question as well. I cannot get the selected row value of an attribute in an iterator for a view if I simply set-up a attribute binding to the iterator. It seems that this should be possible. I've had no other option but to obtain the current row and the related attributes programmatically. This works fine, but if there is a more elegant option, then I'd certainly like to use it.
          <af:table value="#{bindings.CompaniesView1.collectionModel}"
                        var="row"
                        rows="#{bindings.CompaniesView1.rangeSize}"
                        emptyText="#{bindings.CompaniesView1.viewable ? 'No data to display.' : 'Access Denied.'}"
                        fetchSize="#{bindings.CompaniesView1.rangeSize}"
                        selectedRowKeys="#{bindings.CompaniesView1.collectionModel.selectedRow}"
                        rowBandingInterval="0" id="tCompanies"
                        summary="Companies"
                        width="100%"
                        rowSelection="single"
                        binding="#{CompanyBackingBean.companiesTable}">Page Def:
    <attributeValues IterBinding="CompaniesView1Iterator" id="Id">
      <AttrNames>
        <Item Value="Id"/>
      </AttrNames>
    </attributeValues>I should be able to get the Id attribute value of the current selected row using "#{bindings.Id}", right? Well, it doesn't work for me. Any ideas?
Thanks

HT204268; I have purchases on an aol login pre 2008 and all recent stuff under an apple id. I currently see and use everything when i login with the apple id. After March 31st will my apple id account still show and contain all?
I understand the instructions to create a new account id (apple id) from the old aol account. However, does this mean my purchases will be split into 2 accounts; or does the fact that I currently see everything under my apple id (regardless of the purchased by username) mean this will all still appear in my current account as it does now?

You see them where when you login your non-AOL account ?
If you currently have two accounts (the AOL username account and an email address account) then you will continue to have two accounts, and nothing should change when you update the AOL account to be an email address (apart from how you access that account).
You will just be renaming the account to have an email address for accessing it, not creating a new account.

Tabular Form - submit custom data and insert/update records

I have a tabular form with 2 columns representing table data and 5 more custom columns.
Task ID
Task Name
10/7/2013 to 10/13/2013
10/14/2013 to 10/20/2013
10/21/2013 to 10/27/2013
10/28/2013 to 11/3/2013
11/4/2013 to 11/10/2013
1
TASK1
2
TASK2
3
TASK3
I use an sql which returns null values for columns 3 to 7. Then I use the html formatting option of apex and jquery to add change the headers to weeks and add checkboxes.
My sql: select task_id, task_name, null week1, null week2, null week3, null week4, null week5 from <table name>
My table has the columns task id, task name , start_date and end_date.
When the user clicks the submit button, i need to send the checkbox data to my stored procedure and insert records into the corresponding table. I am unable to find out how to send a mapping of the task_id, date headers in each column and the checkbox data to apex back end and process them. For example, if the first check box in first row is checked, i should insert a row with values "1, TASK1, 10/7/2013, 10/13/2013". I also have to read the data from the table and display it in the same format. Please let me know how to accomplish this in apex.

instead of using null, you can use apex_item api to create check boxes
read http://docs.oracle.com/cd/E37097_01/doc/doc.42/e35127/apex_item.htm#CHDDCHAF
you can set the value of check boxes using apex_item api and then the value can be captured in your process
check this: Martin Giffy D'Souza on Oracle APEX: APEX Report with checkboxes (advanced).

Custom tabular form for multi-row not saving data

Ok, before anyone asks, yes, I did read the how-to:-)
I have a custom tabular form, which I did cause I need to use popups and the popups that you can use in the wizard tabular form does not display the text but rather the value underneath it.
It returns data rather nicely and when I go and update values I can tell it is changing the fields underneath. I put a process in that will display the values in text fields on the form (for one row only) and I see them changing from what is already there and with the proper values.
However, when I do that the data that is displayed then gets reverted back to what it was previous to the update but reports that the process was successful.
I have also tried to insert but that is basically doing the same thing. Can anyone guide me.

Florian,
Checkboxes are different from other HTML form items. When you have a text box for example, there's always a value send to the server when submitting. Even if that value is NULL. When you have a checkbox however, you only get the value if the checkbox is checked. It's not posted to the server when it is not checked. That's the general behavior of HTML forms and not specific to Oracle HTML DB.
When working with tabular forms in HTML DB, you can access your form values using the htmldb_application.g_f0x arrays. Now if you have for example 10 rows in your form, then you'll get ten elements in your array for text boxes, select lists, etc. For checkboxes however you'll only get as many elements as you have rows checked. If I read your update and insert code correctly, you're trying to use the checkbox arrays the same way you use the arrays based on other item types. My recommendation would be to use Yes/No select lists instead of checkboxes or at least use select lists initially to get it working and then work on properly processing the checkboxes.
Some general information about working with checkboxes in tabuar forms can be found here:

Hope this helps,

Tabular form - adding new row

Hi,
I have a very simple table (5 rows, 1 of which is the primary key), and want to update the table using a tabular form. On initial display, the primary key column is protected (cannot be changed) which is ok for DELETE and UPDATE options, but when I come to ADD A NEW ROW, the new row has NULL defaulted as the primary key value, and will not let me update it !!
Does anyone know how I can leave the primary key column protected when UPDATING or DELETING, but allow a value to be entered when ADDING A NEW ROW ?
thanks
Tim

Andy,
Just made the following changes (to remove NARR1_CODE_DISPLAY and show and edit NARR1_CODE):
select
"NARR1_CODE",
--"NARR1_CODE" NARR1_CODE_DISPLAY,
"NARR1_LOWER_LIMIT",
"NARR1_UPPER_LIMIT",

where the column NARR1_CODE is my primary id, and in the report attributes, NARR1_CODE is now editable and shown as a "text field" . NARR1_CODE_DISPLAY has been removed.
However, when I go into my form screen, although the NARR1_CODE field is now editable, when I click ADD NEW ROW, enter the details for a new row, check the box alongside the new row and click SUBMIT, I get the following error message :
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 = "A884FA378C851786DDFE3A33709CB23C", item checksum = "F6395FDACE39D98E784F85C19D960620"., update "GRD_DD10_OWNER"."DQ_PD_TRANS_DIST_BAND_NARR1" set "NARR1_CODE" = :b1, "NARR1_LOWER_LIMIT" = :b2, "NARR1_UPPER_LIMIT" = :b3, "NARR1_RMP_MIDPOINT_1" = :b4, "NARR1_RMP_MIDPOINT_2" = :b5
sorry about this !
thanks
