• Tip to avoid the keys during the page load?

  APEX: Request Express 4.2.6.00.03

  I have two or three "intentionally" pages slow and heavy and end-users fortunately repeatedly press buttons and harmless error messages.

  I would avoid the situation of "remail" and have the "error messages" in trying to repost.

  Good tips to do just that, I hope that Oracle Apex those compatible upwards?

  1.) page attribute, indicates 'small wheel' until this that totally made?

  I would avoid the 3331 error when the page is defined as "NO page to prevent it being published" or avoid the message concerning the violation of page protection then repost is allowed.

  For example show "spinning wheel" or "progress bar" which blocks of keys user?

  2.) or have this 'small wheel' specific to the region, as well as the region's "spinner" up to full charge.

  3.) or how to display the buttons placed on the page after the 'big jobs are done?

  4.) or some other method?

  Actually, it's the question - if we leave the decision of development which approach to take:

  -make all the shares of dynamics of buttons and everything for example plsql anonymous to be driven by the dynamic action procedures of instead of making procedures plsql after send this page

  - or do the submission page process (pre era dyn-action method apex) and no dynamic action with plsql code button

  The apex is basically PL/SQL.

  So in order to generate a page of Apex, PL/SQL code should be run. To update a report region, code PL/SQL must be executed. To deal with the elements on a web page to the update/insert/delete of data in the database, PL/SQL code must be executed. Etc.

  This code can be executed in 2 ways.

  Submit the entire page, the flow of the Apex engine. He built a whole new page. This page is sent to the browser to replace the content of the existing window and make any new content in this browser window.

  Use Ajax (Javascript calls) to call the flow of the Apex (aka action/process dynamics) engine. It creates a response (XML, HTML, JSON, etc.). This response is returned, and Javascript is used to treat this response and update objects (e.g. add/update / refresh in the DOM) of the page.

  The two ways are necessary as

  (a) we want to send a new page to the web browser sometimes

  (b) you want to update an existing web page in the web browser by moments

  So it is not a matter of choice in one direction. The two are concerned. Both are needed to create Web 2.0 with rich and interactive interfaces type applications.

  I'm just afraid after accidentally 2 similar submit deals plsql firing - dynamic action and one in present it after Treaty.

  It's a question of developer and development life cycle.

  It comes down to knowledge. Find out what are the differences between the page layouts and dynamic actions. And when to use one that to achieve the goal at hand.

  Lets say that we have to report slow query and report region which takes time to load. But this report is not required for the end user and it could continue by pressing the buttons during the loading of that specific region is always.

  Press the buttons to do what? And why the user would click the buttons when the report data are not yet ready for display?

  The Javascript engine doesn't have a thread model Posix/Windows type.  By default, its calls are non-blocking and use events. See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/EventLoop for more details.

  This isn't exactly a walk in the Park to treatment systems simultaneous good design. And it's true in Javascript too.

• Error #1009 during the Page move or page elements

  When I try to move a page or any object on a page, I get an error and then Muse shut. I restarted. I uninstalled and reinstalled Muse twice, and both times I have this problem. I ran repair permissions. Nothing has solved the problem that I am running Mac OS 10.10.1 Yosemite.

  Here is the error message:

  Adobe Muse CC has encountered an error and will now close. Please report the last actions bit that you have taken to this error to the Adobe Muse CC team.

  [NDMI/nativeDragEventHandler] TypeError: Error #1009: cannot access a property or method of a null object reference.

  

  Restart your Mac. Drag Mac OS x Manager is in poor condition. This will result in accidents or other misbehaving in Muse and a few other applications when you attempt to drag objects with the mouse. The only way to fix it is to restart your computer.

  Apple seems to be addressed to this bug in OSX 10.11.3. In addition, the next major upgrade of Muse, 2015.1, has been revised to use a different approach using the Manager of Drag of OSX to avoid this bug in older OSX versions.

• Initial request on the Page loading

  Hi all

  I use Jdev 11.1.2.3.  I have a page with a simple table based on a view.  I want that he executed not the query when the page loads.  Now that I've seen many comments on this question and blog of Shay spot on that too, but what I see is the following.  When I have the table on a tab of the Panel with nothing else dressed the steps previously suggested, if the value of itterator #{! adfFacesContext.initialRender} and or affecting the value #{bindings. {LocalDate.inputValue not null}, seem to work splendedly.  But when I put a collection of panels around the table the methods above do not seem to work.  What I lack or y at - it another way I can get cela no query when the page is loaded?

  Thanks in advance for any advice.

  Steve

  #{! adfFacesContext.initialRender} is not very good approach to accomplish your use case, because sometimes is not clear what exactly is 'initial render' (for example, when you have defined a workflow set as region...)

  Instead, you must call YourViewObject.executeEmptyRowSet () before you navigate to the page.

  To learn how to execute the method before loading the page, see this blog: https://blogs.oracle.com/adf/entry/an_epic_question_how_to

• Dynamic action does not not on the first attempt to load page. Work after refreshing the page

  4.2.1

  Hello

  I have a page with a list of selection Order_id and a display _item Product_name.  There is action dynamic PL/SQL that fills the element displayed when the order_id is changed. The problem is that when I opened the page for the first time, if I change the select order_id list, nothing happens. But if I refresh the page once, and then it starts work and the display_item is filled.

  No idea what could be the problem?

  Thank you

  On a more serious note,.

  1 when you load the page for the first time and try selecting the order_id, nothing don't be past, try refreshing the page once and you will see the option to display with the null value. What I do is. I have two tables

  Orders

  1

  2

  3

  Products

  1A

  2B

  2 Z

  3 C

  When I select the command 1, then since there is only one line of products, the displayed item will indicate A populous. If I select 2, since there are two product lines, I should see the list box.

  Doesn't seem to work and I'm sure, I'm doing something wrong.

  Difficult to be certain that as it appears that someone has been editing the page before you start watching (rather than copy the page experience their own copy). Your article P1_PRODUCT_NAME_DISPLAY he a point value / Expression 1 column = Expression 2 condition P1_HIDE_SHOW = 1 condition on that? Or any other condition of rendering?

  These conditions do not match the dynamic actions. They are applied only during the page see the transformation when the page is displayed first; When it is linked to another page; or after a branch to him. They are not applied dynamically during the activity of the user on the page. In this case, that the status is set to false when the page is rendered first, the same element does not exist in the page sent to the browser. If you want these items to appear conditionally because of the interaction with another user control, then you must initially return the elements and control their visibility using hide/show the dynamic actions.

  You don't tell us your version of JDeveloper.

  An easier approach to implement your condition is to use the property refreshCondition of your iterator. Here is an example of how do: https://blogs.oracle.com/shay/entry/delay_method_execution_when_us

• Initially Web pages load very slowly, but are a lot faster if I stop and reload the page

  Whenever I have initially load ANY page of a Web site, the first page really takes a lot of time to load. All pages of this site is loading very quickly thereafter. I also noticed that if I stop the loading of the page, immediately after my first click and then click on reload, the page loads almost instantly. I am currently using Firefox 20.0.1, but this problem has occurred for a while... at least as far as Firefox 19. According to my research, I've tried a bunch of suggested solutions, but nothing helps... including: off hardware acceleration, don't select any proxy, disabled ABP, etc.. Any other suggestions would be greatly appreciated. Thank you!

  Hello stw203, maybe try to reset all the related settings in your network configuration. enter Subject: config in the bar firefox address (confirm the message information where it appears) & are looking for any preference, starting with the network in bold (= set of users) - do a right click and put these entries to their default value.

• Conditional branch to submit during the loading of the page?

  Hi all

  I have a page (REPORT PAGE) which serves as a setting for the reports and is called from several places in the application.  The calling page sets various parameters on the REPORT PAGE.   The REPORT PAGE displays all parameters and has a button "run report".

  The user presses a button (submit page) to run the report and after that the report is displayed to the user is returned to the calling page.

  I want to change the behavior so that the calling page has the possibility of a parameter causes the report to run immediately - effectively by pressing the button and automatically submit the page.

  The concept would be 'submit a conditional on load '.   Anyone see a workaround to achieve?

  Depends on what is meant by "report". When you use the word, always explicitly if you are referring to a standard report of the region, an interactive report, a shared component of report query or a custom build you just happens to describe themselves as a "report". Please explain the nature of the "report" in detail, using the standard terminology of APEX.

  It sounds like something that would be managed by setting the REQUEST in the target URL or the branch on behalf of the "run report" button If the 'report' depends on the page accept the processes after a click on the button "run report", use the special form BRANCH_TO_PAGE_ACCEPT in conjunction with the value of request button causes the page to be submitted in the first place, for exampleBRANCH_TO_PAGE_ACCEPT|RUN_REPORT

• 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).
  
  
  Concerning
  Bottom
  
  Published by: bottom of Klerk on 2013-apr-11 07:43

  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.

  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

• How to set the initial value of the same value as the Page loading of SelectOneMenu

  Hello
  
  I noticed that in my value = "#{bean.selectedItem page}" of selectonemenu is always null when loading the page and because of that there is a difference in the initial value and the value sent as valuechangelistener is shot because of this difference, I don't want to happen. "
  
  I call the method to load the values into selectonemenu in the constructor of my bean.
  
  How can I make sure that the initial value is always the same as the value at the time of page load so that valuechangelistener would not fire unless the user changes the options in selectonemenu. Because of this problem I am facing a lot of issues like valuechangelistener is going to get fired.
  
  Any help is much appreciated.
  
  Thank you

  Yes, you will need to find a way to set the value before the creation of the part of the view. Generally, there are two ways. There are at least two ways, I tend to use:

  (1) loading deferred; you would get a Get accessor like this method:

  public String getValue(){
    if(value == null){
      // code here to get value from wherever
    }
  
    return value;
  }
  

  (2) initialize properties in a method annotated with @PostConstruct in your backing bean

  @PostConstruct
  public void initialize(){
    value = whatever;
  }
  

  Hope that helps you. If this isn't the case, so I totally misunderstood you and you try to explain more clearly what your problem is.
