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

Can i use partial page rendering with BC4J?

Hi!
I can't use partial page rendering when i use table for bc4j...
Why is it?

Why do you say that? It seems to work fine for me...

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 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

Same problem here (no graphics in header or footer) and the problem has been reported months ago. It is another bug/feature lost when Apple moves from 09 to the iCloud-compatible versions. Complain to Apple, you may have better chance than me and they may finally listen to their users....

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

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

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

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

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

Need help to import and syncronize HCM pagelets with Interaction Hub, how can I do that?

Hi,
I need help to import and synchronize HCM pagelets with Interaction Hub, how can I do that? The default page "Select Remote Content" of the WorkCenter "Unified Navigation WorkCenter" is not working as well, when I run the import/sync button I get the following error message:
Integration Gateway: General Connection Failed (158,10836)
This error is thrown when there is no valid response.
Possible errors include:
Bad gateway URL
Sync Service Timeout set and Service actually timed out.
Java exception thrown - Check Application Server for possible Java exception

Do you have integration configured between the two systems? It sounds like you don't from the error. Here is a walk-through on setting up Unified Navigation although it assumes you have integration already working. If you haven't done that, it's documented a hundred different places.

The computer that I used to sync my Ipad with crashed. How can I copy the pictures from my Ipad to my new computer?

The computer that I used to sync my Ipad with crashed. How can I copy the pictures from my Ipad to my new computer? When I try to use Picassa to import them I can only see the 'Camera Roll; folder but I have several other folders with hundreds of pictures in them

To copy photos to your computer that were taken with the iPad, copied to it via the camera connection kit, or saved from emails/websites then see this page - on a PC you can use the windows camera wizard
To copy photos that were originally synced from a computer you will need a third-party app on your iPad such as Simple Transfer which can copy them off via your wifi network. But as photos are 'optimised' when they are synced to the iPad, any that you then copy back to a computer may not be exactly the same as they originally were on your computer.

When printing two-sided from my Mac on landscape A4 with 2 columns, how can I get my HP Photosmart 6520 to print the same way up?

Or, it is set the other way around (which makes more sense). Even though you are in Landscape mode, it is binding on the Long Side of the paper. Since you are in Landscape, you would want it to bind on the short side.
Think of the Binding like a Book. How would you flip the finished pages to read the “book.” Where it would be bound in the imaginary book is how you want it to print.

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
Best,
John
