Problem getting the pageFlowScope number parameter in backing bean

Hi, I use a taskflow with parameters of type oracle.jbo.domain.Number.

I want to replace a method in my grain of support in order to take the value of the parameters pageflowscope.

(inMarkNbr, inColorNbr)

But I take as the result the following error:

Error: oracle.jbo.domain.Number cannot be cast to impossible

Error type: class java.lang.ClassCastException

StackTrace:

view.backing.pages.AutoProfile8.doApply(AutoProfile8.java:17)

Could you help me please?

    }
}

paste here shoot to screen with your definition of parameters TF and tell us, what exactly is the line

view.backing.pages.AutoProfile8.doApply(AutoProfile8.java:23)

ClassCastException occurs?

I suspect that you are a parameter defined as impossible. The exact type of the parameter must be oracle.jbo.domain.Number, exactly that.

In addition, a color as a set mark

Mark oracle.jbo.domain.Number;

color oracle.jbo.domain.Number;

mark = new oracle.jbo.domain.Number (markObj);

  • How can I get the total number of pages printed on my LaserJet 3055?

    I have a nice 1012 LaserJet that is not supported in Windows 7, but there is a solution which is to set up a Vista driver as if the printer is a LaserJet 3055.  It works, even if sometimes I get a printed statement that it does not work, and when that happens I just turn off the printer and turn on again immediately and it is fine.  I would like to know if there is anyway I can get the total number of pages printed at some point, as I could with the LaserJet 1012.

    P.S. This thread was moved from software for Laserjet. -Hp moderator of the Forum

    Please ignore my post on the LaserJet 3055.  With the help of a good soul on another thread of discussion, I was able to install and operate my LaserJet 1012 printer on Windows 7, exactly as it did in XP.  No errors, no slow printing, no problem.  The LaserJet 3055 thing helped initially as a work around, but the message about the bad personality who stopped the printer until you turned off and turned it back was boring.

  • Can I get the total number of records that meet the conditions of a query using the Table API?

    Hello

    A < row > TableIterator is returned when I ask operations using the index of tables. If I want to get the total number of records, I count one by one using the returned TableIterator < row >.


    Can I get the total number of records directly meets the conditions of the query?

    I can get the total number of records directly the request of the meeting of the conditions of CLI using the command Global table - name tableName - count - index index-name-field fieldName - start startValue-end endValue.

    Can I get the same results using the Table API?

    I used MongoDB and NoSQL Oracle for about a year. According to the experience of the use of these dbs, I think mongoDB querying interface is powerful. In the contras, the query interface is relatively simple, which results is a lot of work that is usually a long time in the client side.

    Hello

    Counting records in a database is a tricky thing.  Any system that gives you an accurate count of the records will have a hotspot of concurrency on updates, namely the place where the counting is maintained.  Such a count is a problem of performance in addition to competitive access problem.   The problem is even more difficult in a system widely distributed such a NoSQL database.

    The CLI has overall command that counts, but does so by brutal force - iterate keys that correspond to the parameters of the operation.  This is how you must do this within the API.  There is not a lot of code, but you have to write.  You certainly want to use TableIterator TableAPI.tableKeysIterator (), because a key iteration is significantly faster than the iteration of lines.  Just one iteration and count.

    If you use TableAPI.multiGet () and a key with a touch of brightness full then, in fact, count the results as they are returned in a single piece (a list).

    Kind regards

    Best regards

    Customer service does not help with purchases made elsewhere nor do they help with installation problems product aged.  If the indication is that you have already used the number, it is likely, you have done but never made use of it, in which case is is you keep it for you.  Your only recourse would be with the one who sold you the card.

  • lost the cd to acrobat reader 9.5.5, how can I get the serial number before I recreate the image on the pc, what is?

    A few years, our company purchased Acrobat Reader 9.5.5 Pro for one of our employees. This employee is no longer with us, so we want to clean up the pc and re-purpose it. Unfortunately, we have more drive, in that the program has come. So the question is, how can we get the serial number for the program so that we can reinstall it once the pc is under image?

    Acrobat Reader is free. Acrobat Pro or Acrobat Standard costs money. The problem with serial number is delicate. If it is a payment business with a license so you can connect to your account a retrieve serial number. If it has been registered to the user and he registered the software on a corporate email account, you can probably log on the account and retrieve serial number (I don't know if it's legal, then you can check with your corporate lawyer). If is a an installation an installation of volume then check with the company you bought your contract in volume of might be the best route.

    If you have any of these options at your disposal, you can contact the customer service with proof of purchase in hand. No one will take the word of someone call on a phone, even if they do not tell the truth.

    Please be aware that Acrobat 9.5.5 will not work with several modern operating systems it's quite long in the tooth. You may be able to get some, but not all of the features to work.
