• How to disable the activity of the user during query execution.

  Hello
  
  I use jdeveloper 11g, I have the choice of a Select on a JSF page that executes a query when the user changes the selection, now I would like to warn the user interaction until the query is complete, I tried to disable the other controls like this:
  
  someControl.setDisabled (true);
  vo.executeQuery ();
  someControl.setDisabled (false);
  
  The problem is that the 'someControl' will not get updated until the procedure ends so it does not have disabled.
  
  Any clue?
  
  Thank you

• How do 'Enum Control' disabled during the execution of an executable application and make activated when the application is stopped/abandoned?

  Hello

  I use a "Enum control" on the façade of an executable application built with application builder for LabVIEW 2013 full professional development system. I want Enum control remains activated prior to execution of this request so that I can choose any value from the list of available numeric values, but when I run this application; Enum control should become disabled so that the user can not select another value in the list of data during application execution values so that the default setting remains unchanged during the execution of this application. Enum control must also be activated when the application is stopped/abandoned so that the user can select any value.

  Could someone pls suggest a solution to this problem?  If I select the active state' to 'Disabled' in appearance tab then all listed values becomes disabled.

  Concerning

  Jamal

  I suggest to use the node property of persons with reduced mobility.  You can then disable the enum at the beginning of the program and then activate it in the judgment.

• Questions HFR - "5200: query execution error: invalid item ID".

  Hi all

  We use the Hyperion HFM 11.1.1.3 application. We have recently upgraded to the Oralce Database 11.2.0.2 and reconfigured the HFM application with this new version of the database. When I tried to run the Financial reporting via the HFR studio, I get the error message - ' 5200: query execution error: invalid item ID ". Please could you help me solve this problem.

  Thank you

  Michel K

  It was because of the default angle that is invalid for the user which was inconsistent with the special report.

  Change the preferences to the preview from the user Point of view and rerun the report.

  File > preference > Financial Reporting > preview select 'ON' box under the Point of view.

  Re-run the report, then select the desired POV.

  This will prompt the user to change their POV every time that he or she opens a report. They can select the correct POV and the report runs successfully.

  You can turn off later. Let me know if it solved that problem.

• Development of a feature of single line with list items

  Hello
  I am new to Oracle forms. Currently using Oracle forms 6i.
  I am facing a problem when you check the condition of the components of a line while choosing the "item in the list. I basically multiple data block. On the block of data I assigned to the property as 'Item in the list' to one of the element. This list item has three options 'MANUAL', 'AUTO' and 'ADVANCE '. When I choose the 'MANUAL' list item, corresponding line should be editable and the user can insert the record in the same row. But when I choose 'AUTO' or 'ADVANCE' only the specified element say for example the element 'Sr.no" only be editable while all other elements are unchangeable. I tried to use set_record_property for 'MANUAL' and that my point. But writing set_item_property to "AUTO" and "ADVANCE", which spoils the feature then 'MANUAL' for the line/record after having inserted a line 'AUTO' or 'FORWARD '.
  Please help as soon as possible because it is urgently needed.

  I agree with Gregor uses WHEN-LIST-CHANGED-relaxation. But I wouldn't set the INSERT_ALLOWED and UPDATE_ALLOWED properties in a WHEN-NEW-FOLDER-iNSTANCE-trigger, but put in the WHEN-LIST-CHANGED-trigger and in the process of filling the block (I don't know how the block is filled, if its done using EXECUTE_QUERY the relaxation would be POST-QUERY-relaxation).

  The statement to make it a feature in the Insertable current record is

  SET_ITEM_INSTANCE_PROPERTY('BLOCK.ITEM', TO_NUMBER(:SYSTEM.TRIGGER_RECORD), INSERT_ALLOWED, PROPERTY_TRUE);
  SET_ITEM_INSTANCE_PROPERTY('BLOCK.ITEM', TO_NUMBER(:SYSTEM.TRIGGER_RECORD), UPDATE_ALLOWED, PROPERTY_TRUE);

• Custom list item changes when you click

  I'm having a strange problem.

  When my list of messages is filled first, she checks a property in the json data to see if the message is 'read' or 'unread '. If it is "no read", it will be a different color than those who are already "read" to indicate to the user.

  It works very well, however I added an action context to the list, and when this action is triggered, I'm changing the message "unread". If the color of the list item to change. This works.

  However, after I changed the color of a single item in the listwhen I do scroll down and down, many elements change color. I think it has to do with the rendering of the list of recycling.

  This behavior does not occur after that list first initializes. Regardless of the colors have been queued to initialize their place. Only after that I have an amendment to one of the elements in the list, things go crazy when I scroll. I hope I'm being clear.

  How can I stop this from happening?  This is the code that changes the color of the label in my custom list item.

   listItemComponents: [
                              ListItemComponent {
                                  MessageListItem {
                                      id: messagesListItem
                                      contextActions: ActionSet {
                                          ActionItem {
                                              title: "Mark Unread"
                                              onTriggered: {
                                                  if (messagesListItem.isNew == false) {
                                                      var selectedItem = ListItemData;
                                                      messagesListItem.isNew = true; //property of list item is changed to unread
                                                  }
                                              }
                                          }
                                      }
  

  And inside the MessageListItem.qml

  property bool isNew: ListItemData.data.new
  
     onIsNewChanged: {
          if (isNew == true) {
              subjectLabel.textStyle.color = Color.create("#FF4500");
          } else {
              subjectLabel.textStyle.color = Color.create("#000000");
          }
      }
  

  Please let me know if you have any questions, any help or suggestion is appreciated. Thank you!

  Hello!

  I think that it doesn't because you are not changing 'new' dataModel element variable. In addition, assigning directly control isNew breaks property DataModel is bound to it.

  It should work if you change the dataModel instead.

  An important point to note, however, that it is not possible to change the individual variables of dataModel point. You need to replace the entire item. The code example for GroupDataModel: (not tested, so may require tweaks, tell me please if you need help in getting this work):

  onTriggered: {
    var selectedItem = ListItemData  // get a copy of dataModel's item
    selectedItem.new = !selectedItem.new  // modify it's property
    messagesListItem.ListItem.view.dataModel.updateItem(indexPath, selectedItem) // update the model
  }
  

  For ArrayDataModel, the function is named differently.

  In addition, this line seems suspicious:

  property bool isNew: ListItemData.data.new
  

  Probably, it should be replaced by this one:

  property bool isNew: ListItemData.new
