• Local service of custom data not available in the page template

  Hi guys,.
  
  I created a custom service that is return of Image in response as shown below:
  public void GetImage
  Producer = config.getProducerImpl () (producer);
  String capText = producer.createText ();
  m_binder.putLocal ("capText", capText);
  BufferedImage bi producer = .createImage (capText);
  m_binder.setContentType("image/JPEG");
  m_binder.m_contentType = "image/JPEG";
  AA ByteArrayOutputStream = new ByteArrayOutputStream();
  Wrapper DataStreamWrapper = new DataStreamWrapper();
  Wrapper.m_dataType = "image/JPEG";
  Wrapper.m_clientFileName = "image.jpg";
  ImageIO.write (bi, "jpg", aa);
  wrapper.initWithInputStream (new ByteArrayInputStream (aa.toByteArray ()), aa.toByteArray () .length);
  This.m_httpImplementor.sendStreamResponse (m_binder, wrapper);
  }
  
  I call this service into the page as a template below:
  
  & lt; img src = "http://localhost/ucm/idcplg?IdcService=getJcaptchaService" / & gt;
  
  & lt; input type = "text" name = "capText" value = "<!-$capText - > ' / & gt;"
  
  
  <!-$capText-> capText value is empty here. It is not available here.
  
  Please suggest how capText value may be available in the page template.
  
  Thank you

  Your custom class must extend a class of Service. Then use this line of code to access the value of the variable capText:

  String lCapText = this.m_binder.get ("capText");

  Let me know if it works!

• [Table ADF Faces component] How to save the current state?

  Hello
  
  the ADF faces table component is great!
  You can drag-and - drop columns, sort columns...
  
  Now, we have an obligation to save the State of the table for subsequent sessions.
  The return of the user wants to get the same State as last time (order requirement or sort of column), even if he comes back a few days later.
  Is this possible?
  
  I discovered, that this information is stored in the session cookie. But this cookie is discarded in a few minutes...
  
  Any tips?

  fschulze,

  If you use 11 GR 1 material - you can read about MDS in chapters 33 and 34 of the Fusion for the ADF Developer's Guide - it does exactly what you ask... an update, don't know if it will save the sort order, but the documentation specifically mentions column reorganization as being recorded.

• Not available in the Page properties of fonts pulldown

  When I create a new html document, and then click Modify > Page Properties is not the drop fonts.
  
  I don't know what preferences I changed and does not know how to get it back. I noticed that when I change now, background color and margins that they appear in the body instead of css tag also which is weird.

  I'm guessing that you do not have "Use CSS instead of HTML tags" selected in the General preferences.

  Hello

  You must add the id of the selectOneChoice as partialTriggers to the panelGroupLayout - check my example above.

  partialTriggers="soc1"
  

  Also, you seem to keep the selectOneChoice inside the panelGroupLayout (who you want to fake visible). So, once you make the invisible panelGroupLayout, the selectOneChoice (which is inside your panelGroupLayout) will become also invisible. Cordially (put out the panelgrouplayout if she not how you wanted it to be).

• Refer to the ADF faces RC component of programming client-side

  Hello
  One tried to access component customer adf in a taskflow-ADF using javaScript with its id
  I have an ADF taksflow including a pagefragment. The taskflow is encapsulated by a region r1 in a jspx page.
  I'm trying to access the component of
  
  document.getElementById("r1:componentName"); or
  AdfPage.Page.findComponent ("r1:componentName");
  AdfPage.Page.findComponent("::componentName");
  
  None works. The only way that works is to use
  var firingComp = event.getSource ();
  ...
  firingComp.findComponent ("componentName");
  
  However, as I call the function javascript from an Applet, I get entry to the event of shooting. So if I have to do it this way, I need to define a global varibale, assign him when another JS function called during an event of the ADF is triggered (for example, adf button click...)
  Then use this variable in the JS function called from cmdlet to locate the required component. It is quiet that annoying the user needs to interact with the adf page before that.
  Any suggestion?

  Hi vbokar! ;)

  I check your application and I noticed that the political ADF seems be grayed in JDev so I re - run the Configuration Wizard for the ADF security.
  Other changes were:
  

• user "vbokar" was added to the application role 'testRole1 '.
  <>changed the password of the user vbokar for "password1" (so I can test it)
  
• changed the home page or from the success_url of ' / TestPage2.jspx ' to ' / faces/TesPage2.jspx.

  Run and Viola! It works!

• PHP pages: output error check available and continues to save the page

  Hello

  I noticed that the error output check (green or red) in the Dreamweaver footer bar (on the left of "glimpses of the unit", "browser preview" and icons 'size of windows') is not available in the pages with the .php extension, .html to.

  In addition, Dreamweaver ask me to save the page whenever I change something.

  For example, if I use 'commands-> format source' in a .php page, Dremweaver ask me each time to save it to complete this command.

  Is this a normal behavior?

  I use the latest version, CC 2015 (7714 build), OS X Yosemite.

  No, this isn't a bug, it's how DW. DW needs to have the file saved to be able to produce live view, and Yes, it sucks that the characteristics of the Live view mode are lost when in Design mode.

  Live view is still in its infancy since Adobe has begun to put the elements in Live view mode. If all goes well, they will see a way to overcome the ongoing pop-up from happening.

  Regarding the PHP support, this has always been a minimum feature. If you want a good PHP editor, then there are a lot of options such as

  By default, the value of the CLAIM is reset before show page processing begins. To apply a value available in the page see the transformation, it must be defined in the URL of the page when a request or redirect or specified in the property of the request of an industry. In both cases, the current value of the APPLICATION can be stored by reference using the substitution of static text ( &REQUEST. ), or the value of an element of a page or application session state provided using static text substitution ( &P101_FOO. )

  In this case, you will need to create a branch and make it conditional on the submit button.

• Combination of ADF Faces and JSTL is advisable or trap?

  Dear all,
  
  Our applications(ADF/Webcenter) of fusion using JSTL and ADF Faces inside is advisable or pitfall. ADF Faces features are enough or do we need to rely on the JSTL functions? I prefer to use ADF Faces/JSF functions without the combination with others.
  
  for example 1
  
  
  < jsp:root xmlns:jsp = "http://java.sun.com/JSP/Page" version = "2.1".
  xmlns:f = "http://java.sun.com/jsf/core".
  xmlns:h = "http://java.sun.com/jsf/html".
  xmlns:af = "http://xmlns.oracle.com/adf/faces/rich".
  xmlns:fn = "http://java.sun.com/jsp/jstl/functions" >
  
  for example 2
  
  < jsp:root xmlns:jsp = "http://java.sun.com/JSP/Page" version = "2.1".
  xmlns:af = "http://xmlns.oracle.com/adf/faces/rich".
  xmlns:f = "http://java.sun.com/jsf/core".

  Hello

  Our applications(ADF/Webcenter) of fusion using JSTL and ADF Faces inside is advisable or pitfal?

  To suggest a rule: feature edge try ADF Faces before reaching out to the JSTL. The difference between JSTL and JSF in general, is that the JSTL expressions are evaluated in compiling page while JSF expressions are evaluated deferred. This difference can have an impact on the PPR updates and data rendering (which, in many cases I guess you can fix by defining the ADF Faces, content delivery component immediate instead of deferred). On a light background, I scored with a JSTL alert 'heads up' for this reason

• Mix ADF Faces with HTML, JavaScript, CSS, JSTL question

  Dear all,
  
  The project is now starting to deploy to the production server. When we try to deploy to the production server who made a lot of mistake. As this used widely used project mix ADF faces with
  HTML/JavaScript/CSS/JSTL. I would like to know what are the most error when we have mixed to use each one and how can we overcome them there?
  There is in the project
  
  1 mix of tags html with ADF Faces components
  2. the use of JavaScript/CSS inline
  3. mix the JSF/ADF Faces and JSTL tags
  
  Help me how to address this issues as well as links to useful blog.
  
  JDeveloper IDE version: 11.1.1.5.0 with Webcenter

  Hello

  In addition to this project widely used mixture ADF faces with HTML, JavaScript, CSS, JSTL.

  JavaScript, CSS, and JSTL is not a problem, whereas - according to the JSF version - HTML is. JSF 2 is the first version of the JSF, which allows you to mix HTML with less side effects, if you use Facelets as view declaration language.

  I would like to know what are the most error when we have mixed to use each one and how can we overcome them there?

  There is in the project

  + 1. mixture of html with ADF Faces components tags +.

  This could ruin your pages, lead to update issues and - in case of frequent use in the trees - even destroy the functionality

  + 2. online use of JavaScript / CSS +.

  Poor performance because of heavy weight pages. If you were using ADF Faces and your JS addresses the DOM instead of the architecture of client cJavaScript ADF Faces then chances are JS will fail for the components that have changed their HTML output (which has an impact on the DOM structure) or changes are not submitted to the server.

  For CSS, CSS inlineStyle not applay to the DOM element that is external, which means for example af:input the background text color will color the lavel

  + 3. mix JSTL and JSF/ADF Faces tags +.

  Dependa on how you do. JSF has postponed EL syntax, which means that EL resolves at run time, whereas JSTL resolves at compile time. So the race conditions could become a problem

  Overall, it is difficult to say if things were coded wrong in the project (although for the use of HTML you can be sure) without seeing the code. It seems that the team that built the application however did not dare to the suite of recommended practices

• ADF Faces: refreshment at one point

  Hello
  
  (using JDeveloper 11.1.1.3.0 and ADF Faces and perhaps elsewhere in the ADF)
  
  -(q1) how can I refresh (part of) a page at a specific moment in time on the server (without user interaction)?
  
  It seems to be possible using the vote (with the af:poll component), but since it is based on the interval it seems less appropriate refresh at a specific point in time on the server.
  
  Also, using a component of af: activeOutputText that something seems possible to display the current time on the server (automatically changing) without user intervention.
  
  See the sample application
  at http://www.consideringred.com/files/oracle/2010/PointInTimeRefreshApp-v0.01.zip
  and the screencast
  at http://screencast.com/t/ZTE0MGY3Mzkt
  
  I was wondering if a response to (q1) might be somewhere in a kind of combination between the component af:activeOutputText and the af:poll component.
  But any suggestions for answer (q1) are welcome.
  
  Thank you very much
  Jan Vervecken

  I think that you have the code that calculates how much time left between now and the time you want to do a refresh.
  Then set this interval as interval for the component af:poll - in the event of expiry of survey, you can disable or set another interval.
