How to access the value of component
Hi I wan to show/hide a panelBox according to the value in a box (a database in a table field).I want to render... or something like that to #{expression that gets the current value of the line of the field chechbox}
It was simply: BLOCDONNEES. On the GROUND... but here I am naïve how to get
Thank you kquizak
Hello
in forms, it gave you the current data of the selected line. Do the same thing in ADF (always keep in mind that it is a web application and either a thick client)
-Assuming you're on JDeveloper 10.1.3 (because you do not explicitly), set to the tableSingleSelect component autosubmit = true
-on the table, define a ValueChange listener that you create in a managed bean. Ideally this managed bean has the pair Set/getter accessor that
is used by the panelBox
-define a PartialTrigger on the panelBox to reference the id of the table
-In the valueChange relaxation, retrieve the data of table cell you want to use for the evaluation
public void onRowChange(SelectionEvent selectionEvent) {
// keep the default functionality
FacesContext fctx = FacesContext.getCurrentInstance();
MethodBinding mb = fctx.getApplication().createMethodBinding("#{bindings.DepartmentsView1.collectionModel.makeCurrent}",new Class[]{SelectionEvent.class});
mb.invoke(fctx,new Object[]{selectionEvent});
//add your functionality
JUCtrlValueBindingRef wrappedRowData = (JUCtrlValueBindingRef)((CoreTable)selectionEvent.getComponent()).getSelectedRowData();
Row rw = wrappedRowData.getRow();
... = rw.getAttribute("name_of_attribute");
//set the variable to the cell value
...
}
-set the managed bean variable that is referenced by the panelBox to true/false

PS. : JDeveloper 11 is almost similar: there is no such thing as the tableSelectOne component and the EL changed ;-)

How to access the values in column fron a report (region)
Hello
In the region of report footer section, I want to access the value of a column (e.g. name col = COL01) for first place. I know that I can access total number of rows using #TOTAL_ROWS #. Is it possible to do this?
Thanks in advance,
PareshHello
I did not have a v2 to try this out, but try this:
1. in your report, add the following in the header of the region:
<div id="TheReport">
2 - in the foot of the region:
</div> <script type="text/javascript"> var t = document.getElementById("TheReport"); var r = t.getElementsByTagName("TABLE")[1]; var rows = r.rows; var tds = rows[0].cells; var k; if (tds) { for (k = 0; k < tds.length; k++) { if (tds[k].id == 'ENAME') { alert(rows[1].cells[k].innerHTML); } } } </script>
Remove your old javascript code and replace line alert() with all you need to do with the value of .cells [k] .innerHTML lines [1].
This includes in your report in a div tag The JavaScript find it and gets the second table (the table report is a table of the area which is now within the DIV tag). As older versions of the Summit has not used the attribute "headers" on cells, we check the ID values for the column headings in row [0] - once we found the right column, we retrieve the corresponding value according to the data in row of lines [1].

How to access the values of the properties file
Hello
I use Jdeveloper 11.1.2.2
I need to get some of the values of the properties file to use in a java class.
How can I access the .properties file and the values in them.
Thank you
Nigel.Nigel,
If you are using FileReader, you must specify the actual path where the file is located. In your sample, the file must be in "/ foundation/model/am/view/Test.propeties". I guess that you don't have this access path on your system as it look like the path to your source folder.I use the ResourceAsStream like this:
Create a file de.hahn.testproxy.backingbeans.test.properties with the following content:Test=hallo Test2=world
the path is relative my source in the test project path.
Then, I implemented a listener like:
private static ADFLogger _logger = ADFLogger.createADFLogger(XxyyzzBean.class); public void propertiesTestListner(ActionEvent actionEvent) { // instead of using the de.hahn.testproxy.backingbeans.test.properties you have to use de/hahn/testproxy/backingbeans/test.properties InputStream asStream = this.getClass().getClassLoader().getResourceAsStream("de/hahn/testproxy/backingbeans/test.properties"); if (asStream == null) { // file not found _logger.info("file not found"); return; } Properties p = new Properties(); try { p.load(asStream); } catch (IOException e) { e.printStackTrace(); } if (!p.isEmpty()) { _logger.info("Properties: " + p.toString()); } }
and get the result if I bind the listener to a button in the user interface:
Properties: {Test = hallo, Test2 = world} And make sure that the Test.properties file is copied to the output directory.

How to access the value of the 'createTime', or any other property root?
I would like to focus on the value of the property Root 'createTime' in a custom property so that when I load and edit the file, I can still see when the original file was created. I'm sure there is a simple solution, but I can't make it work.
My code of the use is so far along the lines of:
Test_Date var: Test_Date =? (In other posts I've seen code ith "RootElements ("createTime")" and a mention of "Value.VariantDate", but I don't know how to operate).
Call Root.Properties.Add ("Test_Date", Test_Date)

How to access the value of form element in Database Trigger
Hello
Is it possible to access value of form element in triggering the database?
I have the form that at the table base another element called P14_Insert_to_waiting_list, I want to check the value of this question in the trigger Before Insert deletion of update of TABLE1 and take measures to insert, update, delete record in TABLE2.
Thanks in advance
AaliHello
You can do it with the v function.
v('P14_Insert_to_waiting_list')
I think the name of the element is case sensitive, in order to verify that
Edit
You can also use APEX_UTIL. GET_SESSION_STATE
http://download.Oracle.com/docs/CD/E14373_01/apirefs.32/e13369/apex_util.htm#CHDEJEJE
V is just smallerYou can also use the shortcut function V, instead of APEX_UTIL. GET_SESSION_STATE.

Could not access the value of the component off ValueChangeListener
In many cases, I need to use the value of some UIComponent during execution in many places in the application. But the problem is that I could not access the value of the component outside the ValueChangeListener of this component. I tried to store this value in a temporary local variable, I also tried to use the opportunity to link , but it did not work.
This thread changes made on the ValueChangeListener can't think where else
said I should go ahead everything in the ValueChangeListener but is not useful in my case and it's really limit my choice later.
So question is: How to access the value of the element external ValueChangeListener?

Hello
You can create a bean (depending on the application, choose the scope), add a variable with accessors and then use it in the 'value' property of the component.

How can we access the value of the field in a line removed in the buffer of the component?
In the PeopleSoft component buffer when it removes a parent row children lines are also deleted, therefore, not possible to access the value of the field of these lines.
Example: If we have RECORD1 at level 1 and RECORD2 (which contains the INCIDENT_NBR field) at level 2.
If a row is deleted at level 1, level 2 lines are also deleted, but before delete, I need access to the value of INCIDENT_NBR and make sure no line (s) not many for this value in a third record record RECORD3.
If any line exist in the RECORD3 record an error message should appear in the case otherwise the delete process can go.
I put the peoplecode in RECORD2. INCIDENT_NBR. SavePreChange (at the record level) because this control must be carried out in all cases for all the component where my RECORD2 record is used.
When I display the value of the field I always get a null (00000000 digital).
It is possible that in PL/SQL within a trigger, but unfortunately in this case, I can not catch the error produced by RAISE_APPLICATION_ERROR (-20000, 'Suppression of an incident not allowed when there are dagnostics'); in Peoplecode.
Does anyone know if there is a way to get the values of the fields in the deleted lines?
Thank you
A rowset object has two properties
ActiveRowCount
All lines of lines in an exclusive set of deleted rows
Number of lines
All lines of a set of lines included the deleted rows.
So I would say, to loop through all lines and check for deleted rows and make any desired logic, something like:
For & i = 1 to & rs. Number of lines
& line = & rs. GetRow (&i);)
If & row. IsDeleted then
& rec = & rank. GetRecord (1);
& fld = & rec. GetField (FIELD. YOURFIELD);
/ logical necessary * /.
End - If;
-End;

How to set the value of something in a component of the main application?
Hello
Maybe I've worked on it too long, but I can't understand how to set the value of the text property of a text entry field in my main application component in a block of mx:Script. I have a component called Login in the components folder, and I need to set the text value of empNum. In my statement of mxml up there, I said these components such as xmlns = "components.*" so, logically, the property, I'm putting a c.Login.empNum.text. I can't understand the correct syntax to make this work, and I've tried everything I can think of. Does anyone have any suggestions? I think this should be easy, and there is just something missing me.
Thank you!
HolliHave you tried to give him an id?
If later you can make the loginScreen. empNum.text = "my text".
