MAF: How to allocate a value in a selectOneChoice or a selectOneButton?

Hello
I would like to have a default value for a selectOneChoice or a selectOneButton. Then when the user does not select or press an option, this value must be active.
I tried to add a setPropertyListener to a selectOneChoice, but without success.
Kind regards
Jürgen

Here's the solution that worked for me (thanks to Frank Nimphius):
(1) create a bean managed within the scope of task flow with private variables for the values to set the default value, IE.
private string direction = "inbound."
(2) methods get/set of generation for variables
(3) to the value of the af: selectOneButton to bean variables, i.e. #{pageFlowScope.FlightBean.direction}

(4) define a ValueChangeListener with a method in the managed bean, i.e.

{} public void changeDirection (ValueChangeEvent valueChangeEvent)
    AdfELContext adfELContext = AdfmfJavaUtilities.getAdfELContext ();
    ValueExpression valueExpression = AdfmfJavaUtilities.getValueExpression ("#{bindings.direction.inputValue}", String.class);
    valueExpression.setValue (adfELContext, valueChangeEvent.getNewValue ());
}

That's all.

  • How to connect the value of the input string to numeric values

    Hello

    I'm trying to figure out how to connect the value of unique user input string to numeric values. Basically I want the user to enter the name of a gas that I have a list for (I think I put the list of gases in a table >). Then I want to match numeric values 2 'a' and 'b', according to which gas, name of the user has set. These 'a' and 'b' values will be automatically matched with the name of the gas in a list that I put. For example, hydrogen gas has the value 3 for "a" and 4 for "b. when the user puts the ' hydrogen' name in a string constant, automatically 'a' and 'b' must be issued.» I have connect a and b to a formula

    Thanks for any help

    Hello

    It is perhaps not exactly what you are looking for, but perhaps you could use the enumerated data type and the array of clusters of points (a, b).

    Control properties editor:

    Change the representation in the floating point data Type tab type, DBL will do.

    Then go to the Page of display Format and increment 'Numbers' to something greater than 1

    That toggles the column of values on the tab change the items to % .6f, or 6 digits of precision. Uncheck sequential following, values and you're there.

    If you think that's too restrictive, go back the display Format, then select if rating and you can type anything (but, the editor has a hissing fit, so you must load chains and property [] with a property node values programmatically)

    I've been struggling to get OR improve this editor of properties of the years!

    Chuck,

    With color on your bars, you should have enough experience to understand this.

    You're a loop in the table already.  Now you just need a function like table Max and min. loop.  And you may need to transpose the table 2D.

  • Drag the control example and how to record a value of the indicator?

    Hello world

    I want to drag the Boolean buttons on my front panel in the time of execution, how can I do?

    I remember that I have seen an example or why, it's a map on the front panel, but I don't remember the name TT someone knows?

    and the second question is how to store a value of the indicator, like the first time, you set the value and close the vi and run it again, the value will remain unless you change in the second run time?

    Thanks in advance

    Thanks to you two, are there good examples of mouse followed the structure of the event available?

    and my second question is for example: read a file using the vi, I created the first, that the value of all the positions of the button on the front panel, and the 'get file vi extension' shows the name of the file on the front panel. then I close the vi and open it again, the button positions is always there where they are, but the file name string is empty.

    How can I save the filename so indicator when I opened that vi still once, if not the other position button file selection, the filename indicator still shows the previous name?

  • HOW automatically update the values of the attributes in a VO?

    Hi, experts,

    In jdev12.1.3

    There are two attributes in the original Version, when the line is created or updated and sent, these attributes should be updated automatically:

    1 revise_date: the current datetime object is defined on it;

    2 revisor: employee name of the user who is a field in the page will be defined on it.

    I rewrote the code for RowImpl.java of the VO as java:

    public Date getReviseDate()

    {

    return ((Row.EFFDT_UPDATE_CHANGE_INSERT_MODE == this.getETask () .getEntityState ())

    || ((Row.STATUS_NEW == this.getETask () .getEntityState ())) ? (Date) Date.getCurrentDate ():

    GetAttributeInternal (REVISEDATE) (date);

    }

    But it did not work as I hope. What is wrong with him?

    In addition, in order to set the value of revisor, how do I bind values of a reference of a jsf in RowImpl.java of the VO page

    Thank you!

    Or you can update specific attributes in the method DO DML in your EO Impl class
