Display Attribute for Combo Box List of Value

Hi all,
I am wondering that if even for JDeveloper 12c we need to keep doing this work around https://blogs.oracle.com/adf/entry/combo_lov_how_to_display in order to display a meaningful attribute?
Regards

You could, for example. store both of them (old value, along with new one) in the pageFlowScope. You can do that in the valueChangeListener (before calling popup), and use them in the dialog listener...

Regarding input combo box list of values

Hi,
I am using JDev 11.1.1.5.0
I used the input combo box list of values in adf application based on VO.When I type a value in the input combo box and press TAB key,it gives first item of that list rather than that entered value and when I open the list, it shows the repeating values of the first item.
Please suggest me some solutions.

Hi,
hard to say based on your description. Try with 11.1.1.6 or 11.1.17 and if it reproduces, provide a test case based on the HR schema. Is that an option ? Then send it my way in a zip file renamed to "unzip". My mail address is in my OTN profile, just follow the named link left to this reply

Setting value in input combo box list of values programmatically.

Hi,
I have the following requirement.
I have a combo box LOV defined in the column of application table. Whenever the user is trying to change this value, I need to check for a condition and invoke a warning popup with yes/no button and allow the user to change if dialog outcome is 'yes'. If the outcome is 'No', then i need to reset the combo box to its original value. To do this, in the valuechangelistener of LOV, I am invoking the warning popup and control will coming out of the valuechangelistener and dialog listener will be called.
How do i set the combo box value in dialog listener ? and How do I retain the existing value of the LOV if user clicks on 'No' button.

Entity Descriptions are not displayed correctly in Combo box dropdown list

In Web Analysis, Entity Descriptions are not displayed correctly in Combo box dropdown list when entity descriptions from HFM contains a dot(.)
Example:
'Entity A. LTD' becomes 'LTD'
'Entity B Inc.' becomes blank
It seems that everything before the dot is not displayed when opening the combobox.
It looks like it is acting like the option to show short description for entities in HR where the parent-child relation is not shown. This behaviour I don't expect for descriptions. And in my opinion is not an option in Web Analysis.
Does anybody knows the sollution or have seen this issue before?

Hi,
This is a known issue with combo box list of values.
Please follow this workaround:
- Remove ComboboxLOV on Deptno
- Create an updateable transient attribute(Say Dname) of type String
- Define combobox lov with following values:
List Data Source: DeptView1
List Attribute: Dname
List Return Values:
Dname - Dname
Deptno - Deptno
UI Hints: Display Attribute - Dname
- Edit Dname(transient attribute) and provide following groovy expression
oracle.jbo.Key key = new oracle.jbo.Key(Deptno);
return DeptView1.findByKey(key, 1)[0].getAttribute("Dname");- Now, you are done and observe that Dname combo box lov shows Description even on selection and change in this combo box sets the Deptno value

Enumeration binding for combo box - missing feature

Hi,
In our application, combo boxes are usually employed for similar purpose as radio button groups: provide the end-user with an exclusive, static list of choices.
Unfortunately, JUComboBoxBinding.createEnumerationBinding method does not seem to follow the same paradigm as JUButtonGroupBinding.createEnumerationBinding.
In fact, for JUButtonGroupBinding, one parameter is "AbstractButton[] buttons", which is used for display purposes (end-user descriptions of the choices), and another is "Object[] valueList", which is the list of values for the corresponding attribute (usually, the valid values in the database for the column).
Meanwhile, JUComboBoxBinding is only receiving one array parameter, "Object[] values", which is used both for display purposes and for database values... This approach is very restrictive, as long as we expect to display in the combo box a descriptive text for the coded value in the database (and localizable, as well!).
Is this a known bug, or am I the first one to have noticed it? Is there any schedule for making this feature available?
Thanks,
Adrian

I'm not sure where my last reply went, so another try.
Unfortunately, I have the same feeling as usual, that my posted messages are not carefully read...
The main issue was the comparison between JUComboBoxBinding and JUButtonGroupBinding, and my question was about the possible future availability of a feature. Nothing about this in the answer...
Could I have an aswer to my original message, please?JUButtonGroupBinding is a custom control provided by JClient and has an api to let a user 'provide' custom Button objects instead of the default 'RadioButton's that would get created if none is passed in. The fact that you could use that to perform LOV kind of indirection of displaying a value other than what's set is 'a side-effect' of the original intention.
FYI, we already implemented an extension to JUComboBoxBinding which is just doing what I was asking for. It is not complex at all:( I was only thinking that it might be useful also in standard...The 'standard' way of getting this behavior you're asking for is to create a programmatic VO as suggested above, with both display/update attribute values and bind it to the ComboBox as an LOV Binding. And yes you can certainly create custom controls extending Swing and use the existing bindings or 'extend' them as per an application need.

How to display data in combo box from xml file.

Hi All,
        I have the data in xml file.
<jukebox>
    <song>

        <artist>Kansas Joe and Memphis Minnie</artist>

    </song>
</jukebox>
and i want to display the only url in combo box list. for that how can load this xml file and how can i show.
Can any one help me.
thanks
Raghu.

Raghuvasa,
Get the XML file data into an XML variable in your code, say var jukebox: xml. Then do
combo.dataProvider = jukebox.song.url
or as a shortcut
combo.dataProvider = jukebox.descendants("url")
The latter will pull out elements with tag name url at any depth in the xml structure, so sometimes you have to be careful, but in your case there should be no problem.

Combo box list update or insert restriction

Dear all,
I have a list item which type is combo box.
it shows the Departments list from the department table at run time.
i populate at through a procedure at runtime.
problem
the user could update the list by writing something into it.
i want to force the user to just select a value from the list, not update or insert.
i change the properties of the list item which prevent insertion or updation,
but it disable the selection from the list as well.
how to prevent the user to write something in the combo box list while giving him the
selection authority using the combo box list item?
Thanks and Regards

thank you dear,
but i want to use the combo box instead.
for popup list there is a problem of the null value,
you must assign a value to the popup list and set its required property to true for doing so.
and the combo box do not need this. and my desired functionality require it.

Customize display attributes for LOV

Hi all,
In normally, when create List of values for attributes :
After we selected List Attribute, next UI hints tab we select Available display attribute, for example: I select two attributes : CountryID and ProvinceName --> that's means multiple values are separated by white space like this: 1 England....The question is how can customize to: 1.England
i want replace "." instance of "space". Thanks

The trick is that you add a calculated attribute to the sql like
select country_id, country_name, country_id || ' ' || country_name as LOV from countries
COUNTRY_ID COUNTRY_NAME                             LOV
AR         Argentina                                AR Argentina
AU         Australia                                AU Australia
BE         Belgium                                  BE Belgium
BR         Brazil                                   BR Brazil
then in you use the country_id to store the selected value and hte LOV column to display the options on the ui.

Programmatically Change Combo Box List

Hello,
I searched heavily on these forums and found answers that were close, but I cannot quite figure out the following:
I have a large number of individual RF assemblies, most having the same test requirements. My plan is to create a combo box (or similiar) from which the assembly number can be selected. This box will then provide a numeric value to a case structure, which will then provide the need test parameters and what not.
I know the combo box list can be populated with a property node and the property node fed by an array. It is my hope to be able to put this info in a spreadsheet file that can be updated as necessary and then imported into the VI at run time. Therein lies my problem.
Using the strings and value[ ] property, I can make the combo box work correctly, but I cannot figure out how to import the spreadsheet into the proper format to feed the property node. I've tried various spreadsheet import schemes offered on these forums, but none quite hit it. I've tried to figure it out on my own, but I'm just spinning my wheels.
Any help would be appreciated.
Thanks.

Hello,
I've attached a VI that I think will help you. I actually used the Index & Bundle Cluster Array function, which I don't think I've ever used before. Anyway, this function gets the two arrays of strings from my tab-delimited text file and manipulates them into an array of clusters containing two strings each, which is the data type required by the StringsAndValues[] property of the Combo Box:
I hope this gets you started in the right direction. Good luck!

Add items to a combo box list if not in existing list

I'm trying to set up a combo box for an expense report form. I want users to be able to select an account from an existing combo box list or to add an account to the list if it doesn't exist already.
Ideal situation:
For example, the user has "Office Supplies" and "Meals - Business Related" as existing options in the combo box. They need to enter a parking expense, which doesn't exist on the list, so they type in "Parking" in the combo box. They attempt to advance to the next field. A message box pops up and says, "Do you want to add "Parking" to your list of expense options? They click "Yes" and the combo box will now include Parking in the future.
Any assistance would be greatly appreciated!

George,
Do you know of a way to save the list addition to the original file without saving any new form data with it? In other words, I would like the item to be on the list when the document is opened in the future, but if they just save it, it will save with the form data they've just entered.
Thanks!

How to display attributes for a CHAR in the Excel file (BEx)?

Hi all,
I knew that I can display attributes for a CHAR (ex: attributes - address, phone#, zip code for CHAR-Customer) when I run Web- based report. But I cannot find this function after I export the file to Excel. In the context menu for excel file, I only see 'select filter'(but no display attribute values), drilldown, properties (for query). Is it something that I cannot have in the excel file for the BEx report?
Thanks
J.

Hi Bhanu,
In fact, I found that I can move IOs in the 'rows', 'column', and 'free CHARs' and so do end user by using 'local view'. That means every one can change the query definition, right?
For your last question, that was what I want to know. How can I prevent 'end users' change those query definitions? Is it about 'role' setting, right? But I am not the one to do 'role' setting.
Thanks for help. (I will asign points when the SDN system works)

Hi all,
I am facing a typical event handling problem for combo box in Swing(Using Net Beans 5.0, jdk 1.4.2)
While adding items to combo box it is firing action event twice instead of once irrespective of no. of items added to it.
For eg if there are 1 or more than 1 item added to combo box it is triggerring action event twice(one just after when first item is added and one again when rest all items are added)
and if there is no item then also it is triggering once.
Can you please help me out.
Thanks

Validation error message is not displayed for an attribute as an Input List Of Value

Hi everyone,
I use jdev 11.1.1.7.0
In my application I've created an Entity Obj and a View Obj base Employees table.
for the JobId attribute I've taken actions as listed below:
1. in Employees EO I've created a validation for this attribute and in some cases an error message returns (the error message is "the salary is not high"):
     * Validation method for JobId.
    public boolean validateJobId(String jobid) {
        if (...) {
            return false;
        if (...) {
            return false;
        if (...) {
            return false;
        return true;
2. in Employees VO I've created a LOV for this attribute (the view accessor is JobsViewObj ) and I display the attribute as an Input Text with List Of Values.
in jspx page I drag& drop this attribute as below:
          <af:inputListOfValues id="jobIdId"
                                popupTitle="Search and Select: #{bindings.JobId.hints.label}"
                                value="#{bindings.JobId.inputValue}"
                                label="#{bindings.JobId.hints.label}"
                                model="#{bindings.JobId.listOfValuesModel}"
                                required="#{bindings.JobId.hints.mandatory}"
                                columns="#{bindings.JobId.hints.displayWidth}"
                                shortDesc="#{bindings.JobId.hints.tooltip}"
                                autoSubmit="true">
            <f:validator binding="#{bindings.JobId.validator}"/>
          </af:inputListOfValues>
I open the Popup and I select a row from the Popup list and then I click Ok. After that if the validation method(validateJobId) returns false, the error message("the salary is not high") must be show to the user. but the error message doesn't display. I don't understand why this happens.
Can anybody guide me about this problem?
Regards
Habib

yes, you're right, I've tested it in 12.1.3 and error message was displayed.
it seems it's a bug(bad bug ) in both 11.1.1.7 and 12.1.2. and now what can I do? is there any way to display the the error message?

Habib

Combo Box - List Value Property

I have a combo box in a form (Forms 10G) which is populated at runtime using values from a parameter table.But when I generate the form it gives a warning message that the list item property has to be filled .
The combo box should display only the values from the database but it should not have any default values.
How can I supress the warning message and avoid entering the list values proeprty at design time.
Thanks in Advance.

The warning is part of forms functionality, but is just that, a Warning, and the form should compile if not an error exists. Not sure if there's a way to suppress it, and You can simply leave the list with no values in Your design, as You will provide them at runtime. If coding is ok Your list should display the values You extract from the DB
