Getting Row and Column in ADF RC

Hi,
I have an ADF RC form with a table control on it. I need to find the row and column of the cell where the user has clicked. I am able to get the row using getSelectedRow() but am not able to get the column of the cell. Could anyone please help?
Thanks & Regards,
Mike

Hi Frank,
I need the coordinates. eg. My table is something like this
Country Region City Value1 Value2 Value3 Total
AAAAA BBBBB XXX 10 15 30 55
EEEEE YYY 5 2 15 22
TOTAL 15 17 45 77
etc.
If the user clicks on any cell in the country column he can add countries, if he clicks on any cell in the region column, he can add regions. The behavior changes for value1, value2, value3... if he clicks in any of these columns he can add value4, value5 columns. If he clicks on the actual data, he gets another screen.
Thanks & Regards,
Mike

Dynamic populate rows and columns in adf table

Hi everybody !
I have a query thats returns a unic value !
and I want to populate an af:table with this value !
i need to execute this query to get the values for each columns .... and jump to next row and continue to execute the query for new values of the columns of the new row !!!
in backing bean ... im try to do someting like this :
RichColumn coluna = new RichColumn();
coluna.setId("id");
HtmlOutputText out = new HtmlOutputText();
out.setId("receive");
out.setValue("Contas a Receber");
coluna.getChildren().add(out);
out = new HtmlOutputText();
out.setId("pay");
out.setValue("Contas a Pagar");
coluna.getChildren().add(out);
this.getTableFluxo().getChildren().add(coluna);
but i get the same values for all the rows !!!!

Hi there,
If you use ADF BC you can make transient variable in the View Object and fill it in the get method,every time the
get method is executed you will execute the query and change the value of the new transient variable.
Even better solutions is to extend the query with this extra column and map the table with it.

Re: Getting the current selected Row & column in adf table

Hi,
Our requirement is we have to retrieve both the current row and column in adf table.
We can retrieve the current row in the backing bean like
ViewObject view = getViewObject();
view.getCurrentRow();
Is it possible to retrieve selected column id or column header text as we are getting for row?
please give some sample.
Thanks,
Vijay.

Hi John
My exact requirement,
1. We have collection of records in adf table
2. Each cell in the row has commandImageLink (Like adding approver, edit approver, delete etc)
Currently it’s working fine for me in the commandImageLink listener, but the problem is table is refreshed 2 time,
while selecting a record and commandImageLink is clicked, I have to avoid 2 times refreshing,
If it’s possible to identify a particular cell in the row selection, I can avoid the image link listener.
we are using Jdeveloper11.1.1.4.0
Please suggest.
Thanks,
Vijay

Hit the exception when editing the value of row key column in a new created row in a table

1. I created a view object with 2 entity objects (parent table: YARD_FIXED_SLOT - child table: YARD_FIXED_SLOT_DETAIL) and the primary key of child table composes of 2 columns ( one of them is FK: YardFixedSlotDetail.FIXED_SLOT_ID REFERENCES YARD_FIXED_SLOT(FIXED_SLOT_ID)
SQL queries:
SELECT YardFixedSlotDetail.FIXED_SLOT_ID,
       YardFixedSlotDetail.MODIFIED_DT,
       YardFixedSlotDetail.SLOT_FROM_N,
       YardFixedSlotDetail.SLOT_TO_N,
       YardFixedSlotDetail.USER_ID,
       YardFixedSlot.BLOCK_M,
       YardFixedSlot.BLOCK_N,
       YardFixedSlot.FIXED_SLOT_ID AS FIXED_SLOT_ID1,
       YardFixedSlot.SECTION_N,
       YardFixedSlot.STATUS_C,
       YardFixedSlot.TERMINAL_C
FROM YARD_FIXED_SLOT_DETAIL YardFixedSlotDetail, YARD_FIXED_SLOT YardFixedSlot
YardFixedSlotDetail.FIXED_SLOT_ID = YardFixedSlot.FIXED_SLOT_ID
2. I dragged this view object into JSF page as an ediable table and add 'add' button to add a new row to the table. and the handling logic in managed bean is as followed. now one new row can be added succesfully in the table.
    public void processSlotDetailCreation(ActionEvent ae)
        DCBindingContainer bindings = (DCBindingContainer)getBindings();
        DCIteratorBinding dciter = bindings.findIteratorBinding("YardFixedSlotDetailFindAllByBlock1Iterator");
        Row row = dciter.getCurrentRow();
        //get the last row for the index and create a new row for the //user to edit
        Row lastRow = dciter.getNavigatableRowIterator().last();
        YardFixedSlotDetailFindAllByBlockRowImpl newRow = (YardFixedSlotDetailFindAllByBlockRowImpl)dciter.getNavigatableRowIterator().createRow();
        newRow.setFixedSlotId(new Integer(21));
        newRow.setUserId("adftest");
        newRow.setModifiedDt(new Timestamp(System.currentTimeMillis()));
        //bug exist here
        newRow.setSlotFromN(new Integer(1));
        //newRow.setSlotToN(new Integer(1));
        newRow.setNewRowState(Row.STATUS_INITIALIZED);
        int lastRowIndex = dciter.getNavigatableRowIterator().getRangeIndexOf(lastRow);
        dciter.getNavigatableRowIterator().insertRowAtRangeIndex( lastRowIndex+1, newRow);
        // make the new row the current row of the table
        dciter.setCurrentRowIndexInRange(lastRowIndex);
        dciter.setCurrentRowWithKey(newRow.getKey().toStringFormat(true));
        //table should have its displayRow attribute set to //"selected"
       // AdfFacesContext.getCurrentInstance().addPartialTarget(slotDetailsTable);
3. When filling in a new value for SlotFromN column (note that SlotFromN column and FixedSlotId column are the rowKey), hit the exception below:

4. I think problem maybe is related with row key, but I need end user to change rowkey column value. does it allow changing the value of column as row key? I found this problem maybe only occur for new created row. For those existing rows, even I change the value of row key column, no such problem occurred, how do I handle this situation?
Appriciate if anybody can help.

Hi Bangaram,
Thank you for your reply.
The error: "Root cause error code is JBO-34014. Error message parameters are {0=oracle.jbo.Key[21 null ], 1=root} "
I didn't create master records, I just used joint queries for information display of both master and detail. I am trying to create a row in the UI table to create a new detail record and master record already exists.
The row key for new added row in UI rich table is [21 null ], row key of detail records table composes of 2 columns. 21 is for FixedSlotId and null is for SlotFromN. when I provide a new value for SlotFromN column in UI rich table, problem will occur.

Nested Table columns and ADF BC 11.1.2

I'm thinking ahead to a new application design, including a new database design. In this application, there are users who may not change the production tables directly, but their changes must be approved (and possibly modified) before they are applied to the production tables. The production tables are part of an existing system, and are fairly well normalized, with a master table and several detail tables.
So for the new design, I want to have a staging table, mirroring the master table, where user changes are stored until they are approved and applied to the production tables. The staging table contains a few extra columns for "add, change or delete", user who submitted the change, date the change was requested. After applying the change, the staging record is to be copied to a change history table, and deleted from staging. That way, the staging table never has a lot of data in it.
Here's the question:
I need to deal with the detail tables. I could have staging versions of each detail table, but I was thinking that it might be easier to handle if the detail tables were included as nested table columns of the master staging table. Most of the detail tables only contain a few rows per master row. But can ADF BC 11.1.2 handle nested table columns? Is it easy to use in an application?

Thanks for the quick response. I was thinking I might get a response from someone who had tried it, so I didn't waste time trying it myself. I consider your response is pretty authoritative, and I'll take that as a sign that I should forget the nested tables design.
No, polymorphic views probably won't do the job. I think I'll just go ahead and create staging versions of each detail table with foreign keys back to the master staging table. Then I'll let the wizard create the needed association objects and view links in ADF BC. It will complicate the procedure for applying changes, particularly adding a row to the change history table. But that's the price we'll need to pay.
OTOH - I just had a thought - since the change history table is mostly for auditing, it appears in some reports, but has no CRUD in the application, other than the insert when the changes are applied. If I did that insert with a trigger or some other PL/SQL, then the change history could still be a single table with nested table columns for the details.

How to use C:when test... inside column in ADF table

I am using ADF table with below two columns

Dynamically changing row color in an ADF table?

Hi,
I am using Build JDEVADF_11.1.1.3.PS2_GENERIC_100408.2356.5660. Can anyone please let me know the code for dynamically changing the row color of an ADF table?
Thanks,
Vik

well you can use EL on af:column inlineStyle property to change the color on condition
e.g
inlineStyle='#{(row.SelectedRow)?"background-color: Silver":""};a example can be found here it is changing color based on Checkbox selection http://baigsorcl.blogspot.com/2010/06/deleting-multi-selected-rows-from-adf.html

How can i open a PDF bank statement in numbers so that the rows and columns contain properly aligned data from statement?

how can i open a PDF bank statement in "numbers" so that the rows and columns contain properly aligned data from statement?

Numbers can store pdfs pages or clippings but does not directly open pdf files. To get the bank statement into Numbers as a table I would open the bank statment in Preview (or Skim) or some pdf viewer.
Then hold the option key while selecting a column of data.
Then copy
Then switch to numbers and paste the column into a table
Then repeat for the other columns in the pdf document
It would be easier (in my opinion) to download the QFX or CSV version from your bank

How to accessing current row report column value in Lov Query?

Hi,
which access methods (eg. bind variables, substitutions, ...) for getting the current row report column value can be used in the "Lov Query" property of a report column?
As what I know of and what I have read on the forum there are no bind variables for the report columns. For the "Link Text" property it seems that the column values exist as substitution strings (#COLUMN_NAME#). But they don't work in the Lov Query. => And would be good because of a hard parse each time the Lov query is executed.
The following post (Re: Simulating a correlated sub query in lov
is showing a solution to use package variables for temporary storage of the referenced value, but the only problem with that solution is that if a new record is added with the "Add rows to tabular form" process the package variable still contains the value from the last queried row! Is there a way (variable, APEX package, ...) to determine if the lov query is executed for a new record so that the package can return null?
I know that I could write the package in a way that the value is immediately cleared when lov_pkg.keyval is called (one time read), but then I would have to create several variables if I'm accessing the value multiple times in the query or in another query => I think an one time read solution would be very obscurely.
Thanks for your help

Hi Patrick,
I agree that it's a waste to continually use Ajax to go back to the server to get the contents of a dynamic select list.
There are no bind variables for any row item - but what you do have, as per my previous post, is the value of the data entered by the user in the first row. You can pass this into your application process (using get.add("VARIABLENAME", value)), which can use it to retrieve the correct LOV in your Ajax code - this will give you a "bind variable" that your process can use.
What you could do, however, is generate hidden select lists on your page - one for each possible LOV list and replace the contents of the new row's select list with the contents of the appropriate hidden select list. This is easy to do with javascript (using innerHTML functions). Obviously, though, the usefulness of this depends on the number and size of the select lists.
Even if you don't generate them to start with, you can keep a copy of any select lists returned by Ajax in the DOM for use on new rows. So, if you have retrieved a select list, you will have a copy of it in DOM which you can then copy into the new row. If you don't have the list in DOM, use Ajax to get it, store a copy of it and copy it into the new row.
Which method you use will depend on the number/size of select lists needed. If they are few in number and/or size, I would suggest generating hidden lists. If they are large, use Ajax to get them once, store them and then retrieve them from the DOM when needed.
There is another thread here where Arie recommends going to the server every time to make sure you get the most up-to-date data for the lists. If you want to follow this advice, for this reason, use get.add("VARIABLENAME", value) to pass the value to your process. If this is not an issue, you can use one of the other methods I outlined above.
Regards
Andy

Row Selector column on Interactive Report

Hi all,
I have an interactive report based on a custom SQL query. How do I add a row selctor column so I cans select individual rows? I have also tried using a tabular form which also does not display a row selctor column. This is odd as my other tabular forms display a row selctor column.
Many thanks for you help,
Chris

Chris,
Usually when someone wants a row selector, it's to choose a few rows by clicking a checkbox, then doing something with them. I'm guessing that's what you're looking for?
Martin Giffy D'Souza's [blog post|http://apex-smb.blogspot.com/2009/01/apex-report-with-checkboxes-advanced.html] explains one way to do that which should work for you. I haven't tried, it, but it looks pretty comprehensive.
Good luck,
Stew

How to create a report region which the first colomn is row selector column

I want to create a report region and its first column is a row selector column. I have used select sentence to select some columns. But I do not know how set the first column to row selector column. I mean I want to do as follow. When a radio which is first column is chosen, it will return it's value of the column in the chosen row. Please help me! Thanks

Hi unnamed,
Suppose you have an id that identifies your record.
Go to Report definiton, tab report attirbutes.
Select the id of your record.
Create a link to the page you want to go to.
Hope this helps.
If not, I suggest you to create a from with report, and analyze the way the wizard has generated it.

How to get number of rows and columns in a two dimensional array ?

Hello,
What would be the simplest way to get number of rows and columns in a two dimensional array represented as integers ?
I'm looking for another solution as For...Each loop in case of large arrays.

Petri

Hi Petri,
See a attached txt file for obtaining two arrays with upper and lower index values

How do I delete multiple rows and columns in an image?

I am looking into how digital SLRs extract video data from a CMOS sensor. To give an example, the GH1 from Panasonic can record video at 1920 x 1080 from a 12 MPixel sensor that, say, is 4000 horizontal x 3000 vertical. How they do that seems to be not in the public domain, but there have been a few guesses (see http://www.dvxuser.com/V6/showthread.php?t=206797 and http://luminous-landscape.com/forum/index.php?showtopic=38713).
One approach would be to simply read every second row of sensor pixels (1500 rows read from the original 3000) and once you have those in memory, delete every second column (2000 columns left). You would end up with a 2000 x 1500 image which could then be resampled to 1920 x 1080.
I'd like to simulate what the camera appears to be doing, by generating a 4000 x 3000 test image and then asking Photoshop CS4 to delete the appropriate rows and columns. It may not necessarily be every second row; the Canon 5DMk11 appears to read every third row, so I may need to delete two out of every three rows.
Can Photoshop do that sort of thing? If so, how?

Thanks for the suggestions. Yes, I did take a detailed look at your images, but they weren't 100% convincing because it wasn't clear just what was happening. And Adobe's explanation, after reading it again, explains nothing at all to someone who doesn't know how Nearest Neighbor works.
But you are correct -- Nearest Neighbor does effectively delete pixels. I proved it with the attached 6 x 6 image of coloured pixels (the tiny midget image right after this full stop -- you'll have to go to maximum zoom in PS to see it).
These are the steps to delete every second row and then every second column.
1. Select Image > Image Size.
2. Set Pixel Dimensions > Height to half the original (in this case set to 3 pixels).
3. Set Resample Image to Nearest Neighbor.
4. Click OK and the image shoould now consist of three vertical white strips and three vertical Green-Red-Blue stripes.
5. Repeat steps 1-4, but this time set Pixel Dimensions > Width to half the original (in this case set to 3 pixels). The image should now consist of three horizontal stripes Green-Red-Blue.
Just to make sure the method worked for every third pixel, I repeated the above steps but with 2 pixels instead of 3 and obtained the correct White-Green, White-Green pattern.
I resampled the Height and Width separately for the test so that I could see what was happening. In a real example, the height and width can be changed at the same time in the one step, achieving the same results as above.
Finally, how to explain how Nearest Neighbor works in the simple cases described above?
Division by 2
In the case of an exact division by two (pixels numbered from top leftmost pixel), only the even numbered rows and columns remain. To put it a different way, every odd numbered row and column are deleted.
Division by 3
Only rows and columns 2, 5, 8, 11... remain.
Division by N
Only rows and columns 2, 2+N, 2+2N, 2+3N... remain.
To put it simply, a resample using Nearest Neighbor (using an exact integer multiple) keeps every Nth row and column, starting from number two. The rest are deleted.

Lock rows and columns header in a table view report. It is possible?

hi,
I have a Dashboard that displays a report in "Table View" with many rows and columns.
Is it possible to set a lock on the rows and columns like Excel?
This would have blocked such headers that contain attributes and measures and to browse the report (eg with a scroll bar) had always viewed the headers.
Can you help me?
Thanks
