Transient attributes - need help

Hi,
I don't know how to solve this issue and that's why I'm asking for help.
I need to create 3 transient attributes. Imagine that I have EmployeesVO(Id, salary,...) and DepartmentsVO, and this is what I need:
1 - create one transient attribute to calculate the number of employees that one Department has
2 - create one transient attribute to calculate the sum of employees salary from one department
3 - create one transient attribute, in another VO, to calculate the sum of employees salary from one department (point 2) / the number of employees from that department (point 1).
Can anyone, Please, help me? Any ideias? Some examples?
Thanks,
Atena

Atena,
It's just a matter of changing your query to compute them. You don't need to create a VO based on employees and departments EO, you just need to create a department VO which computes its employees in its query (SELECT COUNT(*)). It can be updatable, but the computed field will be read-only, since it's not associated with a physical column of your database.
Yes, when you insert a new employee, those computed attributes will automatically updated. You may have some problem with EO/VO cache, but clearing them will give you the correct value.

    Thanks for identifying utl_particionpackage. I tried to check the code of this package, but it has wrapped, so i cannot see the code.
    But one thing i have observed - If utl_particion.truncate_partition internally calling UTL_SMTP package and I am getting error from this package then this will catch by below code -
             v_sql := utl_particion.truncate_partition('&3','<Table_Name>', v_partition_name);
                if v_sql!=0 then
                     raise_application_error(-20088,'Error in Truncate partition');
                    :Ret := 2;
                end if;and after that it will catch by user define error exception block (This i did not mention in my earlier post)
        WHEN excepcion_ctrl THEN
            dbms_output.put_line (WRN: '|| substr(SQLERRM,4,200));
            :Ret:=0;But it has catch by when others exception -
    I think inside utl_particion.truncate_partition procedure has proper exception handling. So when some error will occur it will return '0'. If there is no proper exception handling then we can assume the error will propagate to When Others Exception block.
    Please tell me my understanding is correct or not.

  • Visible property for transient attribute.

    Hi,
    I am using J developer 11g Release 2.In my page i need to set the visible property for the transient attribute(conform password) because the transient attribute needs to be disable for some condition.I have tried but the property was working only when the attribute is not transient.Can we set the property for transient attribute?
    Help me on this..
    Thanks,
    Suganya.
    Edited by: Suganya on Feb 27, 2012 1:40 AM

    Disabling the visbile property:
    <af:inputText autoSubmit="true" id="it6" label="Table Attr"> </af:inputText>
    <af:inputText partialTriggers="it6" visible="#{bindings.AphdBe.inputValue eq null? 'false' : 'true'} " id="it2" label="Trans Attr"> </af:inputText>like this you should h'd.
    normally we use transiet term in vo's while coming to part ui.
    it will consider as attribute. no thing difference bwtn those attribute as timo says.

  • How to add transient attribute to URL Data Control

    Hi,
    Is it possible to add a kind of "transient" attribute to an URL Data Control on model layer?

    Hi,
    no. it doesn't. Even with ADF BC, the transient attributes need to be held by the business service and not the data control

  • Need help with my usecase based on transient ViewObject

    I am using 11.1.1.4.0 Jdev version. I need help with my usecase.Been trying it for 2 days but couldn't figure out the issue.
    I have a transientVO . In this VO Rows will be populated programmatically. CountryId is an attribute of this VO. I have created a viewAccessor "CountriesVA" from Country VO of HR schema.
    I have a LOV for the countryId which is based on this VA ,getting countries from CountryTable.
    This is the model part which works fine.
    Before the page load i have called  a method to create a row for this transientVO.Once the row is created i can see the SOC in my page which i have created as below.
    Now i want to insert a row in the transientVO if user selects a country and restrict duplicate entry . (As One row is already created 1st time there will be no rows created.after that rows will be inserted)
    The issue is :: Suppose there are 2 countries. A & B .When user does the following actions :
    Insert A . Done //as 1st entry
    Insert B . Done //as 1st time entry
    Insert A . duplicate not inserted
    Insert B . getting inserted // the bug.

    9.7.6 What You May Need to Know About Programmatic Row Set Iteration
    The problem is solved ,the above links helped me solve the problem.
    what i did is i have created a method in appmodule to iterate rows and all the method y operation bindings and my logic works fine ....
    MY Advice to all Adf developers ,though i am not an expert but i can assure you to follow the above process for rowIteration.If you use the  iterator binding in the manage bean to navigate the rows u'll face issues which are unexpected.
    In AppModule :::::
        public boolean createRow(String oldValue,String newValue){
         System.err.println(oldValue+""+newValue);
          ViewObjectImpl vo=getViewObj1();
          boolean duplicate=false;
          if(oldValue!=null){
          RowSetIterator iter = vo.createRowSetIterator(null);
          System.err.println("iterating rows ");
             while (iter.hasNext()) {
                 Row r = iter.next();
                 System.err.println(iter.getRangeIndexOf(r)+" row is "+r.getAttribute("CountryId"));
                 if(r.getAttribute("CountryId").toString().equals(newValue)){
                     duplicate=true;
                     break;
                 // Do something with the current row.
             // close secondary row set iterator
             iter.closeRowSetIterator();
          return duplicate;
    In ManageBean :::::
        public void countryIdVC(ValueChangeEvent valueChangeEvent) {
            // Add event code here...
            String oldValue=null;
           System.err.println("Old Value"+valueChangeEvent.getOldValue());
              setEL("#{bindings.CountryId.inputValue}", valueChangeEvent.getOldValue());
              if(evaluateEL("#{bindings.CountryId.attributeValue}")!=null)
             oldValue =evaluateEL("#{bindings.CountryId.attributeValue}").toString();
                    setEL("#{bindings.CountryId.inputValue}", valueChangeEvent.getNewValue());
            String newValue=evaluateEL("#{bindings.CountryId.attributeValue}").toString();
            BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();
             //access the name of the iterator the table is bound to. Its "allDepartmentsIterator"
             //in this sample
             DCIteratorBinding dciter = (DCIteratorBinding) bindings.get("ViewObj1Iterator");
             //access the underlying RowSetIterator
             RowSetIterator rsi = dciter.getRowSetIterator();
             if(oldValue!=null){
                          rsi.getCurrentRow().setAttribute("CountryId", oldValue);
               OperationBinding operation = bindings.getOperationBinding("createRow");
               operation.getParamsMap().put("oldValue", oldValue);
               operation.getParamsMap().put("newValue", newValue);
          if(!(Boolean)operation.execute()){
          //get handle to the last row
          Row lastRow = rsi.last();
          //obtain the index of the last row
          int lastRowIndex = rsi.getRangeIndexOf(lastRow);
          //create a new row
          Row newRow = rsi.createRow();
          newRow.setAttribute("CountryId", newValue);
          //initialize the row
          newRow.setNewRowState(Row.STATUS_INITIALIZED);
          //add row to last index + 1 so it becomes last in the range set
          System.err.println("Inserting row at index "+lastRowIndex+1);
          rsi.insertRowAtRangeIndex(lastRowIndex +1, newRow);
          //make row the current row so it is displayed correctly

  • Need help in multisim 11? I want to get the transient response of RL circuit....

    Need help in multisim 11?
    I want to get the transient response of RL circuit....i can get the increasing exponential graph in multisim 7 during simulation.....but i am getting a decreasing exponential curve(i.e,decay response) in multisim 11 when i do the same procedure as i did in multisim 7.....how can i get the initial or growth transient response for RL circuit in multisim 11 so that i can get increasing exponential curve....which satisfies time constant = L/R

    Hello,
    The process is the same for any circuit (in this case it is an RC circuit which you sent me). You can find the response on the voltage (which I think it's what you're looking for) at any point of the circuit, as well as any parameter really (R,V,I,L..etc).
    Please refer to the image attached (an analysis on the voltage at an inductor and the wires connected to it).
    The way to set it up (once you're in the transient analysis set up) is, select the Output tab, under Variables in circuit, you can select which parameters to take. V(1) and V(2) refer to the voltage in the circuit at Net 1/2 (or wire 1/2).
    This differs from the voltage change within the capacitor/inductor/resistor. If you would like to see the voltage change of an inductor/capacitor/resistor/etc, you can select under the More options box, the button Add device/model parameter, which will take you to a window to select the device type, its name (in the circuit) and the parameter which you wish to analyse. Once you click on Simulate, you can select Cursor >> Show Cursors, to view information for y and x axis (like rise time, decay time, voltage difference...etc)
    Hope this helps,

    Please check what is the reason for the error.
    I am seeing many issues with VO substitution these days which is because the extended VORowImpl is not calling super for those attribiutes which is overridden in the stanard VORowImpl.
    Please have a read on the below blog and see whether that is applicable to your VO extension.

  • Export Transient Attribute data to excel sheet (from Advance Table)

    Hi,
    I have an advanced table in which its columns mapped with both vo attributes(from database) and transient attributes. If i select 'Export Button' i need to export all data present in the advanced table to excel sheet.. But i am not able to export transient attribute data .. Can anyone help me to solve this problem...
    Thanks,

    Babu
    You should be able to export any attribute from the VO, provided they are not hidden fields. Do the values appear on the screen? What is the field type on the advanced table of the attribute you are trying to export?

  • Difference between EO and VO Transient Attributes

    Guys,
    We do have Transient attributes at EO and VO Level. Are there any difference in that?
    Can you give me use cases where we need to prefer EO Transient attribute instead of VO Tranisent attribute or Vice versa...
    Any help appreciated....

    EO transient Attribute - behave like a column in the db table.. either it can be mapped tothe db column or not..
    VO transient attribte - behaves like a query attribute.. its just used to mape the attribute with the underlying EO attributes.. or for any calculations to be made based on other attributes..

    Referencing custom methods in the EntityImpl class
    If you have defined a method in your EntityImpl class, then this can be called as part of your
    expression for an attribute default:
    adf.object.getDefaultSalaryForGrade()
    Unlike when referencing an attribute of the entity object, which can be done by simply
    referencing the attribute name, when referencing a method, you are required to prefix the
    method name with adf.object.
    So is there a way?
    regards

  • Creating Transient Attributes when query is in Expert Mode

    I wanted to share a recent challenge I encountered. I had created a transient attribute in my View Object and placed it on my .jspx page. When I would navigate to the page I would receive an error telling me, "oracle.jbo.AttributeLoadException: JBO-27022: Failed to load value at index 42 with java object of type java.lang.String due to java.sql.SQLException.".
    After switching my run configuration to include the java option -Djbo.debugoutput = console, I noticed my sql statement was getting modified. I inspected the view object sql and realized the calculation for my transient object was not present. After adding the calculation for the column in my sql, I was able to run the page with no errors.
    My problem was that I had my query in expert mode so I could utilize an outer join. When I added the transient attribute after putting the query in expert mode, JDEV would not automatically make the changes to my SQL.
    It would really help if JDEV threw an alert to the user letting them know that their query is in expert mode and changes cannot be made to the SQL or it would also help if I remembered what I read in the Dev Guide. Such as when a file is read only.
    (JDEV 10.1.3.4)

    When I added the transient attribute after putting the query in expert mode, JDEV would not automatically make the changes to my SQL.Really depends on what you meant by ' transient '.
    Did you really want a 'calculated' attribute - i.e. one that is backed by a query clause - for this you needed to check the 'mapped to column or sql' in the attribute properties and also provide an SQL expression..
    Otherwise, it's just a java 'transient' attribute and doesn't have to be part of the query...

  • Transient attributes

    Cache scheme: replicated
         If our data objects has a few transient attributes (say large attributes, that we do not like to replicate until the need arise, a.k.a lazy loading), how do we code this logic in our put/get API? An example would suffice.
         I think this issue also arises in Coherence *Web, where large attributes can be declared as transient, and are stored as different entities for performance reasons as in ``split'' session model.
         Regards,
         Bulut.

    The easiest approach is to mark the fields as     > transient, then use getter methods with lazy loading.
         > This can read those attributes from the appropriate
         > data source (which may be a cache or even a database,
         > depending on your requirements).
         Do you think Coherence would help in this case? Where would you implement this lazy loading logic? And more importantly, how would it look like? I can see two alternatives:
         i) using Coherence services... maybe using a near cache?
         ii) independent of Coherence? which definitely looks more cumbersome.
         > Coherence*Web simply queries a method which indicates
         > whether a given named attribute should be clustered
         > or not (this class is provided by the application
         > developer). Also, note that Coherence*Web does not
         > lazily load non-clustered attributes; it actually
         > determines whether to make them visible to other
         > cluster member.
         Basically, my question is how Coherence implements handling of transient attributes, if we need a local transient attribute at a remote site.

  • VO Transient Attribute referencing the Attribute from another VO

    Hi I have an scenario where I have a VO "A" has a transient Attribute say aPeriod, (at any given point the executed VO"A" has only 12 Rows) , I have another VO "B" which when executed gives me exactly 12 Rows with attribute "bPeriod".
    I want the 12 Rows of VOA with aPeriod attribute to hold the values from VO"B" attribute bPeriod. Is there any groovy expression / or any View accessor usage which can enable me to resolve this scenario. currently I am achieving this programaticaly by iterating every row of VOA and VOB and assigning aPeriod attribute with bPeriod ( which I am not happy with ).
    Please help me if there is any better solution for the same.
    Thanks
    TK

    Thanks for your reply, but there isnt any common attribute between the two VO, I am having VO1.aPeriod attribute has a transient one and VO2 when executed gives me VO2.bPeriod, actually this is a small subset of a bigger scenario.
    both VO1 and VO2 are SQL based read only VO. both have same query but both needs two different bind variable bindPeriodVariable = 12 and 24 respectively which returns VO1.xPeriod and VO2.bPeriod, when executed.
    I Am supposed to show both VO1.xPeriod and VO2.bPeriod in a single ADF ReadOnly table.
    so I thought of having a transient attribute called aPeriod in VO1 and assign it with VO2.bPeriod individually by iterating every row of VO1 and VO2.
    I am not pleased with the way I am doing this stuff.
    Pls help me with this issue.
    Thanks
    TK.

  • View Object transient attribute (Calculate sum) using groovy problem

    Hi
    I have a read only view object named "ConnectionVVO". And it has database field name "points"(type is number).
    Now I need to take the sum of points.
    For this I did the following.
    Self view object added to the same view object as a view accessor named "ConnectionVVO1".
    Created a transient attribute named "TotalPoints".
    Added following groovy as the value expression of the above transient attribute.
    adf.object.ConnectionVVO1.getRowSet().sum("points")after that when I run the application module and run the view object it was extremely slow. Actually nothing was appeared. There after I modified the sql statement and added a where clouse to select few rows.
    Then it was appeared without slowness.
    The table has around 11 million records.
    Could you please provide a hint or any alternate way for doing this(getting the sum of points).
    Please help.

    Hi Timo,
    Thank you very much for the explanation and direction. I will do that way. I have found that implementing view object and view row class I could do the similar kind of thing for the transient attribute.
    public Number getTotalPoints() {   
    RowIterator con= getConnectionViewImpl();
       Number sum = new Number(0);
       while (con.hasNext()) {     
          sum = sum.add( (Number)con.next().getAttribute("Points"));
        }    return sum;
      } took form
    http://technology.amis.nl/blog/1295/creating-a-dynamic-ajax-column-footer-summary-in-a-table-component-using-adf-faces
    But it also slow as 1 st method
    I am wonder whether both ways behave as similarly or they are totally different implementation?

  • Need help with a currently "in-use" form we want to switch to Adobes hosting service

    Hi, I am in desperate need of help with some issues concerning several forms which we currently use a paid third party (not Adobe) to host and "re-distribute through email"...Somehow I got charged $14.95 for YOUR service, (signed up for a trial, but never used it)..and now I am paying for a year of use of the similar service which Adobe is in control of.  I might want to port my form distribution through Adobe in the hopes of reducing the errors, problems and hassles my customers are experiencing when some of them push our  "submit button". (and I guess I am familiar with these somewhat from reading what IS available in here, and I also know that, Adobe is working to alleviate some of these " submit"  issues, so let's don't start by going backwards, here) I need solutions now for my issues or I can leave it as is, If Adobe's solution will be no better for my end users...
    We used FormsCentral to code these forms and it works for the most part (if the end-user can co-operate, and thats iffy, sometimes), but I need help with how to make it go through your servers (and not the third party folks we use now), Not being cruel or racist here, but your over the phone "support techs" are about horrible & I cannot understand them or work with any of them, so I would definitely need someone who speaks English and can understand the nuances of programming these forms, to please contact me back. (Sorry, but both those attributes will be required to be able to help me, so, no "newbie-interns" or first week trainees are gonna cut it).... If you have anyone who fits the bill on those items and would be willing to help us, please contact me back at your earliest convenience. If we have to communicate here, I will do that & I can submit whatever we need to & to whoever we need to.
    I need to get this right and working for the majority of my users and on any platform and OS.
    You may certainly call me to talk about this, and I have given my number numerous times to your (expletive deleted) time wasting - recording message thingy. So, If it's not available look it up under [email protected]
    (and you will probably get right to me, unlike my and I'm sure most other folks',  "Adobe phone-in experiences")

    Well, thanks for writing back...just so you know...I started using Adobe products in 1987, ...yeah...back then...like Illustrator 1 & 9" B&W Macs ...John Warnock's Helvetica's....stuff like that...8.5 x 11 LaserWriters...all that good stuff...I still have some of it working on a mac...much of it was stuff I bought. some stuff I did not...I'm not a big fan of this "cloud" thing Adobe has foisted upon the creatives of the world...which I'm sure you can tell...but the functionality and usefulness of your software can not be disputed, so feel free to do whatever we will continue to pay for, ...I am very impressed with CC PS on the 64 bit PC and perhaps I will end up paying you the stipend that you demand for the other services.
    So  I guess that brings us to our problem.. a few years back and at the height of the recession and near bankruptcy myself,  I was damn lucky and hit on something and began a small arts and crafts supply service to sell my products online to a very "niche market" ...I had a unique product and still sell that product (plus others) online...My website is www.vinylcouture.com...Strange? Yes...but there is a market it seems, for everything now, and this is the market I service...Catagorically, these are 99%+ women that use these "adhesive, sticky backed vinyl products"  to make different "craft items" that are just way too various and numerous to go into... generally older women, women who are computer illiterate for the most part...and all this is irrelevant to my problem, but I want you to have every bit of background on this and especially the demographic we are dealing with, so we can get right to the meat of the problem.
    OK...So about two years ago, I decided to offer a "plain sheet" product of a plain colored "stick back" vinyl... it is available in multiple quantities of packs ( like 5 pieces, 10 pieces, 15 pieces, in a packi  & so on)...and if you are still on my site.. go to any  "GO RIGHT TO OUR ORDER PAGE"  button, scroll down a little...and then to the "PLAIN VINYL" section...you will see the Weebly website order process.) You can back out from here, I think,..but, anyway this product is available in 63 colors + or - a few. So then the problem is,  how do they select their individual colors within that (whatever) pack?... .
    So my initial idea was to enable a "selection form" for these "colors" that would be transmitted to me via email as 'part" of the "order process".. We tried getting our customers to submit a  " a list" ( something my competitiors still do, lol, poor bastards)......but that..is just unbelievable..I can't even begin to tell you what a freakin' nightmare that was...these people cannot even count to 10, much less any higher... figuring out what colors to list and send me... well, lets just say, it wasn't working......I had to figure out a better way...Something had to be done.
    So after thinking this all out,  and yeah...due to my total ignorance, i figured that we could make a form with Live Cycle Designer (Now Forms Central)...(back then something that was bundled with Adobe Acrobat Pro), I believe, and thats what this thing was authored in... and it would be all good...LOL!
    Well not so simple...as you well know, Adobe Acrobat would NOT LET YOU EMAIL anything from itself.....it just wouldn't work (and I know why, and all that hooey), but not being one to take NO for answer,.I started looking for a way to make my little gizmo work.. So I found this company that said they can "hijack" (re-direct actually) the request to email, bypass the wah-wah, and re-transmit it to the proper parties.....for less than $100 a year,  I think...its called http://pdf-fillableforms.com/.
    A nice gentleman named Joseph Silva helped us program the thing to go to his servers and back out. Please dont hassle them...I need them...for now..it basically does work...try it...you should get back a copy of the form that you filled out...good luck however,  if you're on MAC OSX or similar...
    I have included a copy of both of our forms (and feel free to fill it out and play with it)...just put test somewhere on it...(and you must include YOUR email or it will balk)..they are supposed to be mostly identical, except one seems to be twice as large....generating a 1.7 meg file upon submission, while the other one only generates a 600K file or so...thats another issue for another day or maybe you can advise on that also...
    OK so far so good......In our shop, once Grandma buys a 10 pack (or whatever), Only then she gets to the link on her receipt page ro the relevant "selection form" ,(this prevents "Filling and Sending"  with "no order" and "no payment", another early problem we had)... which they can click on and it will usually download and open up on their device if all goes well...Then our little form is supposed to be fillable and is supposed to ADD UP all the quantities, so grandma knows how many she is buying and so forth right on the fly,  and even while she changes her mind..., and IT'S LARGE so grandma can see it, and then it TOTALS it all up for them, ( cause remember, they can NOT add)..,  except there is a programming bug (mouse-click should be a mouse-up probably or something..) which makes you click in the blank spaces to get to a correct TOTAL...about 70-80% of our customers can enable all these features and usually the process completes without problems for them especially on PC's running Windows OS and Acrobat Reader X or XI...at least for most... Unfortunately it is still not the "seamless process" I would like or had envisioned for the other folks out there that do have trouble using our form....  Many folks report to us the following issues that we know of.  First of all it takes too much time to load up...We know its HUGE...is there anyway that you can see, to streamline this thing? I would love for it to be more compact...this really helps on the phones and pads as I'm sure you well know.
    Some just tell us,"it WON'T work"....I believe this is because they are totally out of it and dont even have Adobe Reader on their machine, & don't know how to get it ( yes, we provide the links).....or it's some ancient version....no one can stop this one...
    It almost always generates some kind ( at least one time)  of "error message" which we do warn them about..., telling one,  basically that "Acrobat doesnt even like this happening at all, and it could be detrimental to ones computer files", blah-blah...(this freaks grandma out really bad)...& usually they end up not even trying to send it...  and then I get calls that even you wouldn't believe...& If they DO nut up and push the Red "Submit Form" button, it will usually send the thing to us (and also back to them at the "required email address" they furnished on the form, thats what the folks at the "fillable forms place" do) so, if it's performing it's functions, why it is having to complain?. What are we doing wrong?....and how can I fix it?...Will re-compiling it or saving it as a newer version of "FormsCentral" correct any of these problems ?
    Ok, so that should keep you busy for a minute and we can start out with those problems...but the next thing is, how can I take advantage of YOUR re-direct & hosting services?, And will it get rid of the error messages, and the slowness, and the iOS incompatibilities ? (amazingly,  the last iOS Reader version worked almost OK.. but the newest version doesnt seem to work with my form on my iphone4)  If it will enable any version of the iOS to send my form correctly and more transparently, then it might be worth the money...$14.95 a MONTH you say. hmmmmm...Better be good.
    Another problem is, that I really don't need 5000 forms a month submitted. I think its like 70-100 or less....Got any plans for that?  Maybe I'm just not BIG ENOUGH to use Adobe's services, however in this case, I really don't care whose I do use as long as the product works most correctly for my customers as well as us. Like I said, If I'm doing the best I can, I won't change anything, and still use the other third party, If Adobe has a better solution, then i'm all for that as well. In the meantime, Thanks for any help you can provide on this...
