• To access the user interface objects in attachedObjects

  I have a NavigationPane and pages get pushed on this as long as the user clicks on the different buttons. The pages are defined as the attachedObjects and are pushed on the NavigationPane dynamically like this:

  NavigationPane{
      id: navigationPane
      property variant myPageVar
  
      Button{
          onClicked:
              if(myPageVar == null){
                  myPageVar = myPage.createObject();
              }
  
              navigationPane.push(myPageVar);
          }
      }
  
      attachedObjects: [
          ComponentDefinition {
              id: myPage
              source: "MyPage.qml"
          }
      }
  }
  

  Now, I would like to connect a signal from a TextField in MyPage element to a slot in my application, something like this:

  QObject::connect(m_pTextField,SIGNAL(textChanging(QString)),this,SLOT(onTextChanging(QString)));
  

  Anyone know how I can do this?  My biggest challenge is a reference to the object Page MyPage * c++, no matter what I can't seem to be able to acquire one.

  There are several options:

  (1) create a Q_INVOKABLE function in your C++ class by taking a QObject * parameter and export the instance to QML class. After you create the page to call this function and pass it the page dynamically. In this function, make the connection.

  (2) the same approach, but use a function without parameters. In the function callfindChild ("Edit") at the scene of the application to find the page. QML assign an object name to the Page after creation to work.

• Access the user interface via TimerTask

  Hello

  I am trying to invalidate the screen for updating a clock of a TimerTask. Unfortunately, I keep getting errors that are probably related to the synchronization of the threads properly. Here is my code for the timer... it runs every 5000 milliseconds:

  public void runTimer()
      {
          TimerTask task = new TimerTask()
          {
              public void run()
              {
                  if (!_dragging && !_screenUnlocked)
                  {
                      UiApplication.getUiApplication().invokeLater(new Runnable()
                      {
                          public void run()
                          {
                              synchronized(UiApplication.getEventLock())
                              {
                                  UiApplication.getUiApplication().getActiveScreen().invalidate();
                              }
                          }
                      });
                  }
              }
          };
          _timer = new Timer();
          _timer.schedule(task, 0, _timerDelay);
      }
  

  Can someone help me understand how to correctly access the invalidate method? Moreover, this method is part of a subclass of full screen...

  You need not be on the wire of event to make the invalidate(), in fact, I would recommend that you aren't.

  There are two common ways to get on the thread of events:

  (1) UiApplication.getUiApplication (.invokeLater)

  (2) synchronized (UiApplication.getEventLock ())

  You must use one of the other, you do not need to use both.

• Best practices for storing the Logs of the system for all newly improved ESXi hosts?

  Hi people,

  What are the options and best practices for the Logs of the system for all newly improved 5.1u1 ESXi hosts?

  Do I need to have the Syslog server or it can be safely ignored?

  Thank you

  Evening,

  Syslog is preferred, but VMware has provided a collector of syslog on the vcenter installation disc can be installed on any windows host or your vcenter. I can't count the number of times where I had guests CMTF or newspapers lost... Fortunately for the syslog which collects up to the accident.  It is not necessary, but it's really a good idea without any real cost since you can use your vcenter host.

• Help - LI running, but get Apache2 Ubuntu default page while trying to access the Web interface of log insight

  Hello

  I installed the Log Insight 2.5 VM via vCenter Server ESXi 5, 5. I was able to deploy the virtual computer successfully and you can see the network through VAPP Options settings. (Attached picture - TIME settings).

  Question:

  Unable to access LI web Interface. While trying to access the Web interface, I get 'Apache2 Ubuntu by default Page' (img attachment). Insight of the newspaper runs and opens the web application on port 80.

  Newspapers, controlled far-

  status of /etc/init.d/loginsight

  Open a session running Insight

  Attached image Loginsight2-DURATION - file /storage/core/loginsight/var/runtime.log

  # sh li - cassandra.sh - status

  SH: li-cassandra-sh: not found

  Check if the tcp 80 port is open through the netstat command. Yes, it is open.

  Telnet on port 80, it says connection and crashes. Image attached - telnet-LI

  Able to ping the IP address successfully.

  How can I check http logs on console LI?

  I would really appreciate response to this soon. I'm working on installation LI for more than a week and struggling to get through this way.

  Thank you

  Radhika

  I believe that you with the configuration, but I tell you that the configured IP address and the IP you hit in your browser are not still the same IP, Log Insight does not work on Ubuntu, so you hit another system. To prove this, connect you to the console of the Insight newspaper and run:

  # cat/etc/SuSE - release

  SUSE Linux Enterprise Server 11 (x86_64)

  VERSION = 11

  PATCHLEVEL = 2

  You will see that you are running SuSE to see a Ubuntu screen tells me that you have an IP address duplicate in your environment and you hit a node that is not an Insight newspaper. I hope this helps!

• What is the best way or best practices for access to the session defined in servelt pipeline component?

  As performance is concerned, a lot would depend on as to how your design & logic is implemented and you presented search operations to support the specific performance problems. In fact the operation itself can be not expensive than in-house it is somewhat like a search for key/value of the objects in session/application context name. But having said that, Yes, a potential performance problem could be because it's a synchronized operation. So to avoid searches to be performed during each request, caching the results of a search of a component. And in the majority of cases to solve a 'A' component within your component, you must configure a property reference 'A' in the file properties for your component.

• To access the check boxes in the user interface programmatically

  Hi all
  I have the following usecase.
  1. I have a table that has 3 columns, first two columns are read only output of the label component and the third column is a checkbox.
  2. I have three lines in the table.
  
  Now:
  1. when a user selects the check box and click on a "submit" button I want to check that it should have selected at least one checkbox.
  2. for which I tried to access the table from the user interface programmatically, but it does not work.
  Is there a way I can access the values?
  
  Thanks in advance,

  Hello

  The box must be bound to an attribute line in the table is related to data collection. If yes then simply loop through the lines and check if the attribute has been set. For example, if each line has a "checked" property, so you can ensure at least a line "checked = true' in your action. To access the collection, you can use something like:

  Object initialRowKey = table.getRowKey();
  try
  {
      int count = table.getRowCount();
      for (int i = 0; i < count; i++)
      {
          table.setRowIndex(i);
          MyObject row = (MyObject)table.getRowData();
          if (row.isChecked())
          {
              // do something, set a flag to true, etc.
          }
      }
  }
  finally
  {
      table.setRowKey(initialRowKey);
  }
  

  The code above assume that you linked the table to your managed bean using the "required" attribute in the table.

• Flatten to a string to send arbitrary objects by messages from the user interface?

  Hi people,

  I am trying to send arbitrary data by messages from the user interface defined by the user to my labview interface. Something funny happens then: if I send the data through the message of ui, it seems I have something strange. There is only one character or nothing in the message of the user interface that reached my reminder.

  It seems that flatten channel also creates control characters that are interpreted by NI TestStand and Labview not as members of the chain, and for this reason I only get incomplete data. within the action of testand, which creates the flattened data, I put a dialog box to display the string data, and it seems that at least up to 255 (ascii) characters are used.

  Is there something like uuencode/uudecode to avoid this problem?

  Thanks in advance

  Okidoki, found.

  His «binary"produced by «Flatten the string» string Apparently I thought, the LabVIEW data type is incompatible with the API of TestStand from LabVIEW. In conclusion I would classify this as a bug (sorry people, at least there should be documentation) API for LabVIEW TestStand 2014.

  As a solution, I use flatten it in XML, which is a printable and human readable 'normal' string.

  It was trial and error, and I'm not enjoying this.

• To access the added Variables of Classes dynamically

  I'm not sure what the terminology is here, but it's what I do.

  I added the officials in the field via a loop and add to the screen

       // loop through all of the elements and setup the forums
          for (int i = 0; i < size; i++)
          {
              c_ForumSelect frm = new c_ForumSelect();
              frm = (c_ForumSelect) v_forums.elementAt(i);

              mainManager.add(new_forum);
          }
  

  I wrote the code that allows to "highlight" the domain manager.

  Is there a way to 'read' the Manager added variables?

  For example, if I had a Variable called 'ID' within the hfm_forumselect... How I acceding that when sound highlighted on the main screen of the user interface...?

  Who is?

  You can add them to a datastructure, a vector, for example. When you add them. Or add the database instead. or you can use the container Manager, navigation using getFieldCount and getField (index).

• Best practices for the integration of the Master Data Management (MDM)

  I work on the integration of MDM with Eloqua and are looking for the best approach to sync data lead/Contact changes of Eloqua in our internal MDM Hub (output only). Ideally, we would like that integration practically in real time but my findings to date suggest that there is no option. Any integration will result in a kind of calendar.

  Here are the options that we had:

  1. "Exotic" CRM integration: using internal events to capture and queue in the queue changes internal (QIP) and allows access to the queue from outside Eloqua SOAP/REST API
  2. Data export: set up a Data Export that is "expected" to run on request and exteernally annex survey via the API SOAP/REST/in bulk
  3. API in bulk: changes in voting that has happened since the previous survey through the API in bulk from Eloqua outside (not sure how this is different from the previous option)

  Two other options which may not work at all and who are potentially antimodel:

  • Cloud connector: create a campaign questioning changes to schedule and configure a connector of cloud (if possible at all) to notify MDM endpoint to query contact/lead "record" of Eloqua.
  • "Native" integration CRM (crazy): fake of a native CRM endpoint (for example, Salesforce) and use internal events and external calls to Eloqua push data into our MDM

  Issues related to the:

  1. What is the best practice for this integration?
  2. Give us an option that would give us the close integration in real-time (technically asynchronous but always / event-based reminder)? (something like the outgoing in Salesforce e-mail)
  3. What limits should consider these options? (for example API daily call, size response SOAP/REST)

  If you can, I would try to talk to Informatica...

  To imitate the integrations of native type, you use the QIP and control what activities it validated by internal events as you would with a native integration.

  You will also use the cloud api connector to allow you to set up an integration CRM (or MDM) program.

  You have fields of identification is added objects contact and account in Eloqua for their respective IDs in the MDM system and keep track of the last update of MDM with a date field.

  A task scheduled outside of Eloqua would go to a certain interval and extract the QAP changes send to MDM and pull the contacts waiting to be sent in place of the cloud connector.

  It isn't really much of anything as outgoing unfortunately use Messaging.  You can send form data shall immediately submit data to Server (it would be a bit like from collections of rule of integration running of the steps in processing of forms).

• The ADF table: filter on columns of stamp with a specific format in the indications of the user interface

  Hi all

  I have problem when filtering on af timestamp column: table.

  I have a table containing historical information (created_on and modified_on), it is mapped to an entity:

  Type = "Oracle.jbo.domain.date"

  ColumnType = "DATE".

  I've seen object mapped from this entity.

  I want to display created_on and modified_on with timestamp (hour and minute), so I add the tips of the user interface for these 2 columns:

  -Type format: Date Simple

  -Size: MM/DD/YYYY HH: mm

  I create a table based on this point of view. The table is filterable.

  The column like this:

  < af:column sortProperty = "#{bindings." View.hints.CreatedOn.name}"blockable = 'true '.

  sortable = "true" headerText = "#{bindings." View.hints.CreatedOn.label}"id ="c6">

  < f: facet = name 'filter' >

  < af:inputDate value = "#{bindings." ViewQuery.queryDescriptor.filterConjunctionCriterion.criterionMap.CreatedOn.value}.

  ID = "id2" >

  < af:convertDateTime pattern = "#{bindings." View.hints.CreatedOn.format}"/ >

  < / af:inputDate >

  < / f: facet >

  < af:outputText value = "#{rank." CreatedOn}.

  shortDesc = "#{bindings." VIew.hints.CreatedOn.tooltip}"id ="ot6">

  < af:convertDateTime pattern = "#{bindings." View.hints.CreatedOn.format} ">"

  < / af:outputText >

  < / af:column >

  When I filter on 2 columns (created_on, modified_on) I got an error: " java.lang.IllegalArgumentException: ADFv: could not convert the instance: 30/07/2014 09:51 type: class java.lang.String in class of type null oracle.jbo.domain.Date."

  Do you have an idea for me?

  Thanks in advance.
