Can we implement partial page rendering on item style Flex??

Hi All,
In an xml,
I have item style 'Flex' for expense account.
Requirement is :
In the same page i have other LOV which brings the data based on one of the segments of that expense account.
So any changes in one of the segments for the expesne account need to be stored and LOV query should be modified accrodingly..
So trying with following possibilties
1) Use partial page rendering for expense account
2) Split the page into two so that first expense account is displayed and any modifications to it are handled in controller and use LOV Mappings to update the query.
So can partial page rendering can be implemented for Item style "Flex".
Can anyone please provide the inputs to handle this scenario and best possible solution?
Issue is very hot right now.. Quick help needed..

Hi
No u can not use PPR for flex items although u can create context flexfield .
thanx

Partial Page Rendering with HTMLDB2.0. How can I do it?

Hi,
somebody told me, that PPR is implemented in HTMLDB 2.0. So not the whole page will be rerendered after a submit but a single region. I know this very helpful feature from the ADF-Java Server Faces. How can I do it with HTMLDB 2.0?
Bye,
Rumburak

Hello,
Take a look at this thread.
Netflix: Nice UI ideas
Also just so you know PPR Partial Page Refresh is an Oracle term you would probably have better luck looking for AJAX or XMLHTTP when looking in the forums

ADF Faces : simultaneous partial page rendering

hi
I'm wondering what I can expect from "simultaneous partial page rendering".
I would like to have some af:selectOneChoice components on a page, with next to them some related information about the selected value.
This example application, created using JDeveloper 10.1.3.3.0, does this using partial page rendering (check README.txt):
http://verveja.footsteps.be/~verveja/files/oracle/SimultaneousPPRApp-v0.01.zip
It as a pprPage.jspx with these components ...
          <af:panelPage title="pprPage">
            <af:panelHorizontal>
              <af:commandButton text="some button"/>
              <af:objectSpacer width="10" height="10"/>
              <af:outputText value="requestCounter.value = #{requestCounter.value}"/>
            </af:panelHorizontal>
            <af:panelHorizontal>
              <af:selectOneChoice label="selectOneChoice A"
                                  id="selectOneChoiceA" autoSubmit="true"
                                  binding="#{backing_PPRPage.selectOneChoiceA}"
                                  valueChangeListener="#{backing_PPRPage.onChangeSelectOneChoiceA}">
                <af:selectItem label="null value label"
                               value="#{null}"/>
                <af:selectItem label="first choice label"
                               value="first-choice-value"/>
                <af:selectItem label="second choice label"
                               value="second-choice-value"/>
                <af:selectItem label="third choice label"
                               value="third-choice-value"/>
              </af:selectOneChoice>
              <af:objectSpacer width="10" height="10"/>
              <af:outputText value="#{backing_PPRPage.selectOneChoiceARelatedValue}"
                             partialTriggers="selectOneChoiceA"/>
            </af:panelHorizontal>
            <af:panelHorizontal>
              <af:selectOneChoice label="selectOneChoice B"
                                  id="selectOneChoiceB" autoSubmit="true"
                                  binding="#{backing_PPRPage.selectOneChoiceB}"
                                  valueChangeListener="#{backing_PPRPage.onChangeSelectOneChoiceB}">
                <af:selectItem label="null value label"
                               value="#{null}"/>
                <af:selectItem label="fourth choice label"
                               value="fourth-choice-value"/>
                <af:selectItem label="fifth choice label"
                               value="fifth-choice-value"/>
                <af:selectItem label="sixth choice label"
                               value="sixth-choice-value"/>
              </af:selectOneChoice>
              <af:objectSpacer width="10" height="10"/>
              <af:outputText value="#{backing_PPRPage.selectOneChoiceBRelatedValue}"
                             partialTriggers="selectOneChoiceB"/>
            </af:panelHorizontal>
            <af:outputText value="userAgentHelper.info = #{userAgentHelper.info}"/>
          </af:panelPage>... and has a backing bean like this ...
public class PPRPage
     public String getSelectOneChoiceBRelatedValue()
          return "some " + fSelectOneChoiceB.getValue() + " related value"
               + ", requestCounter.value = " + ELHelper.get("#{requestCounter.value}");
     public String getSelectOneChoiceARelatedValue()
          return "some " + fSelectOneChoiceA.getValue() + " related value"
               + ", requestCounter.value = " + ELHelper.get("#{requestCounter.value}");
     public void onChangeSelectOneChoiceA(ValueChangeEvent pValueChangeEvent)
          // simulating a slow operation/response
          try
               Thread.sleep(2000);
          catch (InterruptedException ex)
               ; // ignore;
     public void onChangeSelectOneChoiceB(ValueChangeEvent pValueChangeEvent)
          // nothing here to slow things down
}It is important to note that changing the value for the "selectOneChoice A" dropbox has some time consuming operation to perform (possibly calculating/querying the related information to show next to it).
Using IE 6 ("userAgentHelper.info = ... MSIE 6.0 ..."), this behaves like this:
(ie-1) Run pprPage.jspx in JDeveloper, which results in a page that shows this:
selectOneChoice A [null value label] some null related value, ...
selectOneChoice B [null value label] some null related value, ...(ie-2) Select "first choice label" from the "selectOneChoice A" dropbox and immediatly after that select "fourth choice label" from the "selectOneChoice B" dropbox, which results in a page that shows this:
selectOneChoice A [first choice label] some first-choice-value related value, ...
selectOneChoice B [fourth choice label] some null related value, ...(ie-3) Select "second choice label" from the "selectOneChoice A" dropbox, which results in a page that shows this:
selectOneChoice A [second choice label] some second-choice-value related value, ...
selectOneChoice B [fourth choice label] some fourth-choice-value related value, ...Using Firefox 2.0 ("userAgentHelper.info = ... Firefox/2.0.0.12"), this behaves like this:
(ff-1) Do the same as in step (ie-1), which has the same result as step (ie-1).
(ff-2) Do the same as in step (ie-2), which results in a page that shows this:
selectOneChoice A [first choice label] some first-choice-value related value, ...
selectOneChoice B [fourth choice label] some fourth-choice-value related value, ...
questions:
(q1) Why does the related information, for the selected "fourth choice label", not show up in step (ie-2) (as it does in step (ff-2))?
(q2) Why does the related information, for the selected "fourth choice label", show up in step (ie-3) while the value was only/already changed in step (ie-2)?
(q3) Does some general approach exist to prevent "simultaneous partial page rendering" behaviour as described in (q1) and (q2)?
many thanks

JSF: partial page rendering is causing memory leak leading to outofmemory

JDeveloper 10.1.3.2.0
JDK: 1.6.0_06
Operating System: Windows XP.
I test my application for memory leaks. For that purpose, I use jconsole to monitor java heap space. I have an edit page that has two dependent list components. One displays all countries and the other displays cities of the selected country.
I noticed java heap space keeps growing as I change country from country list.
I run garbage collection and memory usage does not go down. If I keep changing the province for 5 minutes, then I hit a java heap space outofmemory exception.
To narrow down the problem, I removed the second city component and the problem still exists.
To narrow it down further, I removed autosubmit attribute from the country component and then memory usage stopped increasing as I change country.
country/city partial page rendering is just an example. I am able to reproduce the same problem on every page where i use partial page rendering. My conclusion is PPR is causing memory leak or at least the autosubmit attribute.
This is really bad. Anyone out there experienced same issue. Any help/advice is highly appreciated !!
Thanks

Samsam,
I haven't seen this problem myself, no.
To clarify - are you seeing this behaviour when running your app in JDeveloper, or when running in an application server? If in JDeveloper, a copuple of suggestions:
* (may not matter, but...) It's not supported to run JDev 10g with JDK 6
* have you tried the [url http://www.oracle.com/technology/pub/articles/masterj2ee/j2ee_wk11.html]memory profiler

Partial page rendering not working in ie9

Hello guys, i have one fusion web application and got menu navigation using partial page rendering. The problem is, the ppr is working fine in firefox, chrome, ie8 and ie7 but not working in ie9. Is it i need to update jdeveloper patch or something?
My ppr setting
put below code in web.xml
<context-param>
<param-name>oracle.adf.view.rich.pprNavigation.OPTIONS</param-name>
<param-value>on</param-value>
</context-param>
for the menu just enable partial submit
partialSubmit="true"

Oh sorry, currently i am using jdeveloper version 11.1.1.5.0. Actually it is not shown any error, when i click the command link as example below, in ie9, nothing happens still displaying same page (my main page).
my sample menu
*<af:commandLink partialSubmit="true" action="page1" text="Page 1" id="cl2"/>*
*<af:commandLink partialSubmit="true" action="page2" text="Page 2" id="cl3"/>*
in task flow, action page1 will open page1.jspx and page2 will open page2.jspx

Global error page - compatible with partial page rendering

My global error page doesn't show in some isolated cases. Could this be because of partial page rendering? What changes might be needed to have it work in all cases?
I have created a global error page and set it in the web.xml with:
<error-page>
<exception-type>java.lang.Exception</exception-type>
<location>pages/htmlErrorPage.html</location>
</error-page>
This displays the htmlErrorPage when errors occur in nearly all my tested cases. However, when the test error is created inside one page redraw I find that the application dies without ever displaying my error page. On the console I get an error message that starts with:
Jun 13, 2008 12:54:11 PM oracle.adfinternal.view.faces.renderkit.core.xhtml.PanelPartialRootRenderer encodeAll
SEVERE: Error during partial-page rendering
javax.faces.el.EvaluationException: javax.faces.FacesException: javax.faces.FacesException: Can't instantiate class: 'com.softrek.adf.view.managed.JFreeChartPlotter'.. class com.softrek.adf.view.managed.JFreeChartPlotter : java.lang.NullPointerException
at com.sun.faces.el.ValueBindingImpl.getValue(ValueBindingImpl.java:190)
at com.sun.faces.el.ValueBindingImpl.getValue(ValueBindingImpl.java:143)
But my error page doesn' t show up. I've used the identical test error in most other parts of my application and it shows - so other than the partial page rendering going on, I can't see why this case would be different.
Is there any known bug (or feature) about the use of an error page during partial page rendering?
Any ideas will be welcome.

I'm unclear on how I would get the error to redirect.
I've changed my web.xml to go to a servlet of my creation, set up the mapping and all.
It works fine for exceptions generated in a backing bean normally.
When the exception occurs as part of partial page rendering the error servlet is not called and the user's session dies.
This is being done in JDeveloper 10.1.3.3
The new web.xml contains:
<error-page>
<exception-type>java.lang.Throwable</exception-type>
<location>/servlet/errorAction</location>
</error-page>
Which is working for errors generated under most circumstances but not when they are inside my partial page change.
How do I get errors to go to my error page when the error occurred during PPR?
PS. Using the PartialPageUtils.isPartialRequest() method generated a recursive error in my error servlet. This looks like the known limitation for Faces error handling.

Can I use voice recognition software with Pages?

Can I use voice recognition software with Pages?

Apple provides Dictation services as part of OS X that must be enabled in System Preferences, and then activated while in the Pages document. Then you can speak and it will type what it thinks you said. It is learning software, and over time, better recognizes your voice pattern.

ADF Faces : partial page rendering in f:subview

hi
Please consider this blog post, "ADF Faces: How-to issue a PPR event from a f:subview and how-to PPR of subviews" :
http://thepeninsulasedge.com/frank_nimphius/2008/02/14/adf-faces-how-to-issue-a-ppr-event-from-a-fsubview-and-how-to-ppr-of-subviews/
In this post, Frank Nimphius writes : "... PPR from a containing page to the subview - unfortunately - only works for the whole subview, which means that the included page is getting refreshed. Because the f:subview component does not support PR, you need to work with a wrapping ADF Faces container, like af:panelGroup ...".
But, it looks like such partial page rendering in a subview can be done without a specific "wrapping ADF Faces container" like this ...
        <h:form id="firstPPRPageFormID">
          <af:panelPage title="firstPPRPage">
            <af:panelHeader text="components on firstPPRPage">
              <af:panelForm>
                <af:panelLabelAndMessage label="dateUtil.currentDateAsString, with partial trigger">
                  <af:outputText value="#{dateUtil.currentDateAsString}"
                                 partialTriggers="firstSubviewID:firstSubviewCButton"/>
                </af:panelLabelAndMessage>
                <af:panelLabelAndMessage label="dateUtil.currentDateAsString">
                  <af:outputText value="#{dateUtil.currentDateAsString}"/>
                </af:panelLabelAndMessage>
                <f:facet name="footer">
                  <af:commandButton text="firstPPRPage button"
                                    id="firstPPRPageCButton"
                                    partialSubmit="true"/>
                </f:facet>
              </af:panelForm>
            </af:panelHeader>
            <f:subview id="firstSubviewID">
              <jsp:include page="/firstSubview.jspx" flush="true"/>
            </f:subview>
          </af:panelPage>
        </h:form>... and where firstSubview.jspx contains something like this ...
<af:panelHeader text="components on firstSubview">
    <af:panelForm>
      <af:panelLabelAndMessage label="dateUtil.currentDateAsString, with partial trigger">
        <af:outputText value="#{dateUtil.currentDateAsString}"
                       partialTriggers=":firstPPRPageFormID:firstPPRPageCButton"/>
      </af:panelLabelAndMessage>
      <af:panelLabelAndMessage label="dateUtil.currentDateAsString">
        <af:outputText value="#{dateUtil.currentDateAsString}"/>
      </af:panelLabelAndMessage>
      <f:facet name="footer">
        <af:commandButton text="firstSubview button" id="firstSubviewCButton"
                          partialSubmit="true"/>
      </f:facet>
    </af:panelForm>
</af:panelHeader>Note the value ":firstPPRPageFormID:firstPPRPageCButton" for the partialTriggers attribute.
see http://verveja.footsteps.be/~verveja/files/oracle/PartialPageRenderingInSubview-v0.01.zip (check README.txt)
questions:
(1) Why exactly does this approach seem to work?
(2) Because of question (1), what could be potential issues with this approach?
regards
Jan Vervecken

Jan,
good job ! I actually never thought of reversing what I said about PPR'ing a component from a subview.
Actually
partialTriggers=":firstPPRPageFormID:firstPPRPageCButton"/>
works because the leading ":" makes ADF Faces to start the component search from the root container. Note that if you use af:form instead of h:form, the trigger is
partialTriggers=":firstPPRPageCButton"/>
I'll update my blog

Partial Page Rendering - newbie question

I am a newbie to ADF and I am in the process of trying out the tutorial "Developing Ajax-Based User Interfaces with ADF Faces Rich Client Components" http://docs.oracle.com/cd/E18941_01/tutorials/jdtut_11r2_56/jdtut_11r2_56.html
I have a question regarding Step 4. I am not very sure where to post this question, if this is not the correct forum, pardon me.
Under "Step 4: Implementing Partial Page Rendering" there is this following comment
In order to have a refresh of the Product Details when you select another row in the Product table, we need to set the Partial Rendering behavior. To do so, perform the following steps:
Similarly On Step 3, sub step 26 states "Finally, double-click on any of the rows in the product table. Notice that the Product Details pane does not reflect the change in the selected product. To implement this synchronization, we need to add partial page rendering functionality."
Question: even before I tried any of the changes mentioned in step 4, I am finding that the product details pane does show information related to the product selected on the panel collection (in other words it is displaying the master detail information automatically). What am I missing here? As per the training document it is supposed to work only after implementing changes mentioned in step 4. Can one of you kindly point out if this is a mistake in documentation or if I have misunderstood the statement?
Thanks
A Sreedhar

Frank,
Thank you very much for the quick turnaround; I appreciate it.
Yes, I am using what seems to be the latest version of JDev (11.1.2.3.0); and yes the ChangeEventPolicy for the iterator is set to "ppr". Thank you for pointing that out.
Does that mean ppr is standard for most components (when I say components, I mean adf tables, button's etc), don't we need to add any special events to get that to work?
I just wanted to see, what will it due if the ChangeEventPolicy for the iterator is set to "None"; made the change saved it, there were two iterators I changed the "ChangeEventPolicy" on both to none; saved it and ran the page. It worked same as before; I was expecting it will not load the corresponding data at the child level, but it did. can you kindly point out what is wrong.
<executables>
<variableIterator id="variables"/>
<iterator Binds="root" RangeSize="25" DataControl="StoreProducts" id="StoreProductsIterator"
ChangeEventPolicy="none"/>
<accessorIterator MasterBinding="StoreProductsIterator" Binds="products" RangeSize="25" DataControl="StoreProducts"
BeanClass="tutorial.model.Product" id="productsIterator" ChangeEventPolicy="none"/>
</executables>
Thanks

ADF UIX Partial page rendering

Hi
I am facing a mysterious problem with partial page rendering in ADF UIX.
My page contains a <header> H1 and inside this there are two headers(H2 and H3).
The partial page rendering is in the header H2 and is working fine.
When i remove the below header H3 the partial page rendering ceases to work and get stuck.

Please suggest if you know of any documentation on ADF UIX partial page rendering.
ADF UIX has very little documentation online and finding it hard to debug this issue.
It ll be of great help.
Thanks
Kamal

Hi Jason,
As of EA9, all rendered components support a partialTriggers attribute. This attribute takes a list of master component IDs. If any of the master components are updated via a partial event, the dependent component will be rerendered in the partial update.
If you are on an earlier release, you should upgrade.
Thanks,
Jeanne

Subtab partial page rendering question

Hi,
I have a subtablayout bean with two adv table regions. The subtab links in the subtabbar bean are set to partial action. When I run the application for the first time, the subtab one is shown and clicking on the second tab, the VO tied to the second adv table is fired but I see only one row in it.
When I click to go back to the first tab and then back to the second tab again I see all the records of second VO now.
I change the action type from fire partial action to fire action for the second tab link. After this, I see all the records displayed the first time I navigate to second tab.
What should I do to see all the records in the second tab the first time I navigate to it while keeping the partial page rendering mode.
Thank you,
Arun

Thank you for your time Srinath.
I used getCurrentRowIndex on the VO tied to the second tab and it returns -1 for the first time as well as subsequent navigations to the second tab.
The table navigation shows "1-10 ..Next" (my setting is to show 10 records at a time in the advance table). It is not showing the 200-201 range.
"getRowCount(..) would explicitly re-execute the query. This answers why you see the whole set of rows when you have this in the SOP. "
I am not sure what you mean here..could you please explain. I understand 'getRowCount would re-execute the query' part. But the normal behavior for the advance table should have been to show the first 10 records since the VO has already been executed once.

Event handler when using partial page refresh ?

Hi
I have a calendar, which uses partial page refresh. The problem is how to make javascript wait until the calendar has loaded and then do some updates on the calendar (after the user has pressed the next button that runs apex.widget.calendar.ajax_calendar('S','next');, for example ). I thought I could add "onreadystatechange" (or onload) event handler to the calendar like this: onreadystatechange="checkState()", where the function would check the state and if ready then do the updates. This doesn't work. Could somebody please tell me why not ?
Tiina

Hi,
It seems that ajax calendar missing event apexafterrefresh.
I do not know is this "bug" or just feature.
That event would be useful to your case , if I understand correct what you looking for.
For workaround , you can over write original function by placing this to calendar region footer
<script>
apex.widget.calendar.ajax_calendar=function(p_calendar_type, p_calendar_action, p_calendar_date, p_calendar_end_date){
var l_cal_type_field = $v('p_cal_type_field_id');
var l_cal_date_field = $v('p_cal_date_field_id');
var l_cal_end_date_field = $v('p_cal_end_date_field_id');
var l_cal_id = $v('p_calendar_id');
var l_calendar_region = 'calendar' + l_cal_id;
if ( p_calendar_type != 'C' ){
$s(l_cal_date_field,$v('p_calendar_date'));
}else{
if ( $v(l_cal_date_field) == '' ) {
   $s(l_cal_date_field,$v('p_calendar_date'));
if ( $v(l_cal_end_date_field) == '' ) {
   $s(l_cal_end_date_field,$v('p_calendar_end_date'));
// create and apex.ajax.widget object
var a = new apex.ajax.widget('calendar',function(){
/* start the return function */
if(p.readyState == 1){
   document.body.style.cursor = "wait";
}else if(p.readyState == 2){
}else if(p.readyState == 3){
}else if(p.readyState == 4){
   $x(l_calendar_region).innerHTML = p.responseText ;
   $s(l_cal_date_field,$v('p_calendar_date'));
   if (p_calendar_type == 'C') $s(l_cal_end_date_field,$v('p_calendar_end_date'));
   document.body.style.cursor = "";
/* DO HERE THINGS AFTER CALENDAR REFRESH */
}else{return false;}
// code for next,previous and today
if (p_calendar_type == 'S'){
p_calendar_type = $v('p_calendar_type');
}else{
$s(l_cal_type_field,p_calendar_type);
a.ajax.addParam('p_widget_mod',p_calendar_type);
a.ajax.addParam('p_widget_action',p_calendar_action);
a.ajax.addParam('x01',l_cal_id);
var lDate = (!!p_calendar_date && p_calendar_date !== '')?p_calendar_date:$v(l_cal_date_field);
if (p_calendar_type == 'C') {
var lendDate = (!!p_calendar_end_date && p_calendar_end_date !== '')?p_calendar_end_date:$v(l_cal_end_date_field);
a.ajax.add(l_cal_date_field,lDate);
if (p_calendar_type == 'C') a.ajax.add(l_cal_end_date_field,lendDate);
a.ajax.addParam('x02',lDate);
if (p_calendar_type == 'C') a.ajax.addParam('x05',lendDate);
a.ajax.add(l_cal_type_field,p_calendar_type);
a._get();
</script>Where I have comment *"do here things after calendar refresh"*, you can hook own scripts.
Of course this is not best way, but might help you till ajax calendar support dynamic actions fully

Jari

How can i share the pages application with another computer?

How can U share the pages application with another computer?

Just make sure it is for you or your family.
If you purchased Pages through the Mac App Store, then just login on the other computer using the same Apple I.D. and you can install it at no extra charge.

How can WLS use JSP pages in a Web Application witth just a JRE [Web Application, WAR, JSP, weblogic.jsp.pageCheckSeconds and JRE]

          How can WLS use JSP pages in a Web Application (either a .war file or a war directory structure) without a java compiler?
          I suspect either the JSP specification is flawed (i.e. it doesn't take account of servers using just a JRE), or BEA's implementation is broken.
          Production servers do not have a JDK installed. They only have a JRE. Therfore a java compiler is not present on the machine that the Web Application is deployed onto.
          On the development machine, when the server is requested to load the JSP it creates a tmpwar directory within the Web Application directory structure. This is then included in the resultant .war file thus:
          D:\war>jar -tf gmi.war
          META-INF/
          META-INF/MANIFEST.MF
          gmiService.jsp
          WEB-INF/
          WEB-INF/classes/
          WEB-INF/classes/com/
          WEB-INF/classes/com/bt/
          WEB-INF/classes/com/bt/gmi/
          WEB-INF/classes/com/bt/gmi/gmiService.class
          WEB-INF/getList.xsl
          WEB-INF/getListByConnection.xsl
          WEB-INF/getListByDistrict.xsl
          WEB-INF/getListByDistrictConnection.xsl
          WEB-INF/lib/
          WEB-INF/source/
          WEB-INF/source/build.bat
          WEB-INF/source/gmiService.java
          WEB-INF/web.xml
          WEB-INF/weblogic.xml
          tmpwar/
          tmpwar/jsp_servlet/
          tmpwar/jsp_servlet/_gmiservice.class
          tmpwar/jsp_servlet/_gmiservice.java
          When deployed on the production server with the web.xml file set to use the following values (note XML stripped):
          weblogic.jsp.pageCheckSeconds
          -1
          weblogic.jsp.precompile
          false
          weblogic.jsp.compileCommand
          javac
          weblogic.jsp.verbose
          true
          weblogic.jsp.packagePrefix
          jsp_servlet
          weblogic.jsp.keepgenerated
          false
          And in the weblogic.properties file:
          weblogic.httpd.webApp.gmi=war/gmi
          I've also tried with the .war file, but that insists on creating another tmpwar directory outside of the .war file.
          Then, although I have set pageCheckSeconds to -1 (don't check and don't recompile) ter production server still attempts to recompile the JSP's:

The default Java compiler from sun lives in the tools.jar that comes with
          the JDK. Just add that to your set of JARs which are deployed in production
          and you should be fine. No need to install the full JDK - just make the
          tools.jar available to WebLogic.
