• No data found in report csv or pdf on first loading of the page

  No data found in report csv output on the first load of the page. Report appears on the page, but no data is available in csv or pdf output. I still need to send the page and then it shows the data in the downloads. The page contains a form (read-only) with a report that refers to 4 page elements by using something like the following:
  
  and b.employee_no = v ('P5_EMPLOYEE_NO')
  and c.fisc_year_pk = v ('P5_FISC_YEAR_PK')
  and b.job_class = v ('P5_JOB_CLASS')
  and b.organization = v ('P5_ORGANIZATION')
  
  Yet once again, report to page appears except there is no data in the downloads. Can someone help me solve this problem? I'm under Oracle APEX 4.2.1 in Oracle database 11 g 2.
  
  Thank you.

  Sounds like a question of classic session state.

  You must eat the page elements using calculations of page rendering to ensure they are set to session state.

  Or if the download is triggered by a button, you should check that the elements of the page are subject to session state, perhaps via an action of PL/SQL.

• Embedded app loads but does not play on first loading of the page

  I have a Flex SWF embedded in an HTML page. After I clear my cache, the swf file loads but does not play. It works very well after that, until I got clear my cache again. I tried my own wrapper HTML basis, as long as the one created by publish Flex. On the first load, if I right click on the swf file, PLAY is not checked. If I check, the swf begins to play very well. Game is checked on subsequent loads.
  
  I tried to add < param name = "play" value = "true" / > in the HTML wrapper with no result.
  
  The app is a basic Hello World with no http request of any kind, just a big label in the middle.
  
  Someone had this problem?

  Finally solved!

  What is happening because of my server (IIS) using dynamic caching. Other people have had the problem with Apache as well.

  Strangely, it only breaks Flex SWF, not Flash SWF.

  In any case, in short, if this happens to anyone, remove SWF in the list of extensions that your dynamic server should cache.

• Error opening the page of modal (plugin skillbuilder) during the loading of the page

  Hi all
  
  I use 4.2.1. (on 11 GR 2), theme 25.
  SkillBuilder Modal plugin v2 page
  
  Modal pages are working on all sorts of events, great, but if I try to open the other via a D.A. on loading the page, it fails with ' Eception TypeError: loading of the object has no method 'stopImmediatePropagation""error (in the browser console). "
  < edit >
  just found out that this error is caused by the "cancel event' DA action that should be fired after the modal dialog box open. If I omit this event Cancel modal page is not loaded, but also no error appears.
  < / Change >
  
  Any ideas on how to solve this problem? In the end, I just want to open a modal window after loading the page depending on the value of an item set when loading the page (the branch sets an element value to indicate that the modal window must be open).

  Bottom,

  The modal shows do not charge is actually quite simple. Look at the generated code for the dynamic action and note in particular the code "javascriptFunction":

  {"name":"modal on load","bindEventType":"ready",actionList:[{"eventResult":true,"executeOnPageInit":false,"stopExecutionOnError":true,javascriptFunction:function(){
     if (this.browserEvent !== 'load'){
        apex.jQuery(document).apex_modal_page('openPageFromApexThis', this);
     }
  },"attribute02":"STATIC","attribute03":"f?p=54687:38:115741808752478:::38:::","attribute05":"data-url","attribute06":"div#success-message","attribute07":"AUTO","action":"PLUGIN_COM_SKILLBUILDERS_MODAL_PAGE"}]}];
  

  You can see that there is an explicit for the browserEvent criterion, and it must be different from "load."

  Of course, when you create a dynamic action with type "Page load", the browserevent will be "load", so no popup and no errors. Running a page in debug and research in the javascript console, you can also click through events fired, for example, I have this in the console:

  Dynamic Action Fired: modal on load (PLUGIN_COM_SKILLBUILDERS_MODAL_PAGE) Object { triggeringElement=document, affectedElements=[1], action={...}, more...}
  

  Firebug allows me to click on the object and display its properties. One of them is the "browserEvent" and set to "load".
  This prevents also the modal open when you actually set the real action of pull on the loading of the page.

  I tested a bit after commenting on prevention onload, and while I'm sure there are reasons why it was built in like that, I have immediate problems. The modal open during loading and anything funky happens, not even when you navigate around in the iframe.
  This does not however only if you want the modal to react on the loading of the page that your only option is to change the the plugin plsql code. I would say: test it enough!

  Go to the plugin, change it. Under Source > Code PLSQL find this:

     l_result.javascript_function :=
        'function(){' || l_crlf ||
        '   if (this.browserEvent !== ''load''){' || l_crlf ||
        '      apex.jQuery(document).apex_modal_page(''openPageFromApexThis'', this);' || l_crlf ||
        '   }' || l_crlf ||
        '}';
  

  and change it to this:

     l_result.javascript_function :=
        'function(){' || l_crlf ||
        --'   if (this.browserEvent !== ''load''){' || l_crlf ||
        '      apex.jQuery(document).apex_modal_page(''openPageFromApexThis'', this);' || l_crlf ||
        --'   }' || l_crlf ||
        '}';
  

  As you can see, I only commented those 2 lines, but it should allow the modal to open the loading of the page. I hope this helps you forward a bit.

• Check if the user has selected box element apex before the loading of the page

  4.2.1

  THM:2

  Hello world

  I have two classic reports with different conditions but even select the columns based on a sql that uses the apex_item.checkbox2 element that allows users to select the lines and run some process. I also have a radio unit that hides and shows these two reports. However, it is possible that the user select a few lines and without doing anything click on the radio button that will present the page and all the lines that earlier he had chosen will be lost. I want that we should be able to pop an alert if there are checkboxes checked and the user tried to hit the button of the radio looks like the APEX_APPLICATION. G_F01. Count is not available at the time the page is submitted. We thought to use a pl/sql to see if APEX_APPLICATION DA. G_F01. Count > 0 then trigger an alert to confirm.

  Any ideas on how to do this?

  Thank you

  Hi FAC586 - basically, there are two parts of the report, were grouped products consolidated (as master) and the other report has all the products of the child. So based on the option the user selects that he sees who discovers and processes information.

  I tried to create the DA, but he does not seem to fire and I'm sure it would be because I have something wrong.

  No, in this case, there was a typing error in my JS expression above (this is what happens when there is no example in the trial against...)

  Must be:$('td[headers="COL_ALIAS"] input:checked').length > 0

  I have page submit on the evolution of radio, given that other elements of the actual application, don't do with this feature which is filled on the loading of the page.

  It does not work. If the present radio on the presentation changes group cannot be controlled by the dynamic action to confirm that it has already been committed before the confirmation message is displayed. Presentation must be made by further action of real on the DA. By the way other values is possible by using dynamic actions or region to submit elements of Page properties.

  But here it is necessary, if the user has activated all the lines, then changes the selection of the radio, it should show an alert to confirm. In addition, what happens if we have a very select in the box by a header label already. Can I use the same label to identify the COL_ALIAS?

  Do not understand the question.

  Don't know what I'm doing wrong.

  As I noted above, an important part of your problem is that you asking what amounts to a series of questions XY rather than the big picture given by presenting the necessary resources. You have been really good on the creation of examples on apex.oracle.com, but they are all fragments of the righteous, which makes things difficult when you try their synthesis in something that works as a coherent whole. Various bits and pieces that have been revealed in recent weeks, it seems like this could be treated using dynamic measurements without having to send the page until the final choice has been made.

• Invoke the backing bean AM prior to the loading of the page

  I have a situation where I need to access the Module from the Application of a bean of support before any loading of the page.

  The method I currently use is:

  AppModule = ADFUtils.getApplicationModuleForDataControl ("MyAMDataControl") (MyAMImpl);

  This works very well if a page in the package that contains has been loaded first. My use case requires us to make that call until all pages in this package have been loaded (and thus AM has not yet been invoked). Any attempt to enter the AM using this method just leaves us with a null object.

  Is there a way to get around this?

  Edit: work with JDeveloper v11.1.1.6.0

  Hello

  both glued by Vinay links are no good solutions for this use case because they don't distinguish between initial and subsequent page rendering rendering (for example applications of PPR). Using the controller in the region, is really not easy to tell when the page rendered first time if you do not work with memory (stored in viewScope) flags.

  If you can, use a method call activity as proposed for the stubborn workflow. Be sure to call dispose method of a created file PageDef activities (click of mouse button allows you to create a law) fault what the method is not part of the life cycle ADF

• Open popup on loading of the page, but with conditions

  Hello.

  I use JDeveloper 11.1.1.7.0

  I need to open a popup on the page load. This problem is recurring, and there are a few messages and discussions in the forum about this. But I need to go further on this subject.

  My case is:

  • Loading of the page, I have to check some conditions.
  • If it's true, popup is open.
    • Popup is YesNo type, and I have a dialogListener to treat the user's response. Finally, the page is loaded.
  • If false, the popup is not open.

  To do this, I use beforePhase like that

  <f:view beforePhase="#{myBeforePhaseMethod}" />
  

  Inside the method, I use PopupUtil.invokePopup (...)

  
  

  Well, my problem is that when the user answers Yes or No, Treaty dialoglistener the answer, page reload, beforePhase is re-run and popup is displayed again.

  How can I solve this? How to display the pop-up window only once?

  Thank you. Best regards

  This ingenious solution has worked.

  First of all, check phaseId in the beforePhase method. Check the phase is MADE

  if (!phaseEvent.getPhaseId().equals(PhaseId.RENDER_RESPONSE)) return;

  Then, use a flag to avoid the popup shows more than once, like that

  String popUpShown = (String)ADFUtils.getPageFlowScopeValue("POPUP_SHOWN");
            if (popUpShown == null)
              popUpShown = "NO";
            if (popUpShown.equals("NO")) {
              ADFUtils.setPageFlowScopeValue("POPUP_SHOWN", "YES");
              PopupUtil.invokePopup( ... );
            }
  

  Any other suggestions or problems it may have are appreciated.

• Tabluar form hide/show items on the loading of the page

  Hi all
  
  Apex 4.1
  
  I use JS to display or hide fields, based on the values of other fields, cela in a tabular presentation. So it is used as a work-around as dynamic actions are not able to do out of the box on tabular forms (that I know of).
  The code I use is something like this:
  
  In the page header:
  
  function test (pThis) {}
  get the index of line curren on changes
  var currIndex = $('select[name="'+pThis.name+'"]').index ($x (pThis.id));
  If (pThis.value < 0) {}
  . style.display $('input[name="f06"]') [currIndex] = 'block ';
  }
  else {}
  . style.display $('input[name="f06"]') [currIndex] = 'none ';
  }
  }
  
  In the attributes of the item in the column 'source '.
  OnChange = "JavaScript:test (this); »
  
  This fires that when the source column is changed, but not working when you load at the start page when it is filled with already stored reports. So it works only when a field is changed to the hand.
  
  How can I force this action shot the loading of the page so the rule (hide fields) also gets applied to existing records?

  Hi all

  Thanks for the comments.
  So far I m unable to make it work. Fire code (debug using alert messages, and these show upwards), but the suggested procedure does not work.

  I tried all kinds of entry points, as for example the test via dynamic when a button is clicked, tried action on loading the page, and also via the $(document) .ready (function
  The function is executed and nothing happends, no error does not code so should be ok.
  I'll investigate further and let you know what happends. Don't know if the class type of the associated field f06 might have something to do with it, but one is LOV/Select list type

  This code is looking for input i.e. text, checkbox etc and will not find a slelect list.

  You must change the jquery like this selector

   $(document).ready(function () {
        jQuery.each($('select[name="f06"]'), function () {
             hide_field(this);
        });
   alert("function executed");
   });
  

• Help! Entertainment reading to the loading of the page, instead of mouse!

  I did research on the response to this problem for hours, and maybe someone can help me as soon as I can help it. I am a new user on board animate and create a drop down menu that appears on a passage from the mouse. Earlier I got it so that the menu does not appear until the passage of the mouse. For SOME reason the drop happens during the loading of the page! I want to stop happening. What is the reason for this? I spent hours trying to solve this simple problem that I created and it does not work.

  I'm banging my head against the wall here!

  Hi, Purduejamie-

  You have autoplay value on?  Click on the scene in the assets Panel and ensure that AutoPlay is not turned on.  The other thing to check is to see if you have errors in your code.  The best thing for you to do is to send your file for the community to look at.

  Hello

  What needs to be done is:
  Set up the STATIC ID for all regions with the exception of the first region.

  For example:
  REGIONTWO
  REGIONTHREE
  REGIONFOUR
  REGION 5

  Then go to the properties of the Page to the section head and footer. In the footer section, add the following:

  You can for example see http://apex.oracle.com/pls/apex/f?p=60428:5

  P.S. If you switch to another topic you should check if the classes are the same. Otherwise it will not work.

• laptop (Dell Inspiron) with Windows 7 Home Premium is now slow to most of the activities - loading of the pages in the browser, etc.

  I heard that after a few years of use, Windows-based computers lose their ability to function. This happened to me before and I bought a new laptop. Now, I think that it happens again. The laptop (Dell Inspiron) with Windows 7 Home Premium is now slow to most of the activities - loading of the pages in the browser, etc... He is also declining my VPN connection occasionally, but also my direct connection is very slow. Latency shows speedtest software provided by the ISP in addition of 250 ms, download speed of 1 MB/s (compared with 8 planned) and 0.05Mbps download. The ISP has corrected this once, but I'm wondering now if it is the computer which is slow rather than on the network because my laptop works well on the same network/router. Is there one solution to this other than another new laptop?

  Jonathan,

  You say that your computer is slow, but all of the examples you give are rather than slow computer operations slow network communications.  To avoid any unnecessary work, check how fast the computer is on the tasks that don't use any network.

  If it works fine for tasks not network then you can concentrate on the problems of network as being the only concern.

  It has also become very slow for no network tasks you should study other causes.  Just as an example: If, like me, you sleep / turn off the computer when you are not using it then defrag will never work, so you can run it manually to make sure that doesn't cause problems.   Describe your symptoms in this thread so that someone can advise on the best course of action.
