Initialize data before page is rendered

How to initialize data into VO before the page is rendered such that data gets displayed in the page?

Hi Shay,
This information is very useful. I have couple of questions.
1. There are two types of controllers
a. subclass of PageController
b. implementing PagePhaseListener
Are there any guide lines on choosing the conroller?
2. Currently I am editing Page Definition class and additing the controller ot it manually is there any way to add it using the tool?

Initialize datamodel before page load

Hi,
i wonder how this is done.
Using JDev 12C and ADF essentials, Shiro.
I have an application with a login page. when the user login i save his userid in the session for general use.
After succesfull login he's directed to a overview page in which all his items are displayed. Problem is, all items belong to other users are display too, and he's not allowed to see those.
So, how do i initialize the data model when i move from the 'Shiro controled' login.jsf page to my index.jsf page?
I've tried using view query criteria but i'm unsure on how and when to initialize it.
I've created a bind variable on the view object and i've published it through the AM and chosen the critera to be effective every time the VO i called.
But i don't receive any data in return if this setup is effective.
I guess it's because i don't have the correct value assigned to the bind variable og view criteria.
I don't know if executeWithParams is the right thing to use but i dont have a button or link to handle the action. It must be performed on page navigation.
Kim

Does your index.jsf page use task flows to present the data?
If so its quite easy - drag and drop the ExecuteWithParams action into your task flow and set it as the default activity. This will execute the query every time the task flow is loaded.

Query is fast, but long lag before page is rendered

Good morning, all!
I have a page that runs a query that returns 518 records. The
page is taking about 9 seconds to load. I added code after the
CFOUTPUT so that I could check the speed of that section and that
shows me that the CFOUTPUT finishes looping over the query after 3
seconds. The CFOUTPUT block is the last code on the page; just to
be sure, I added a window.defaultstatus = 'done' as the line
immediately before the closing body and html tags. The status bar
shows 'done' and then it takes between 5 and 6 seconds before the
page renders.
I realize that this is probably not a CF issue, maybe a
browser setting? Our standard is IE 6.0, which is what I am using.
Any ideas, war stories, resources, or references would be
greatly appreciated.
Thanks,
Kathryn

Any ideas, war stories, resources, or references would be
greatly
appreciated.
How much content is being delivered to the browser. Once CF
is done,
all information in the page must make it down the pipeline to
the client
and then the client has to render it.
If you are doing a lot of looping and|or calculation as CF
builds the
request, you could be generating a mind boggling amount of
extraneous
white space.
There are many ways with which one can use to mitigate some
of this
white space. <cfsilent>, <cfprocessingDirective>
and <cfsetting> tags.
Settings in the administrator, and just restructuring your
code to
reduce white space to name a few.

Calling a method before page rendering begins

I'm new to JSF. I'm looking for a way to get a method from my backing bean called AFTER page contents are initialized but BEFORE the page is rendered. I want to initialize some components dynamicaly and add them as children of an existing component, and then get everything rendered. How can it be done?

What about binding a bean property to your component you wish to add to dynamically?
Could you describe a little more of what you are trying to do? There may be a more elegant way of solving the problem.

Inventory 0IC_C03, issue with historical data (data before Stock initializa

Hi Experts,
Inventory Management implementation we followed as bellow.
Initailization data and delta records data is showing correctly with ECC MB5B data, but historical data (2007 and 2008 till date before initialization) data is not showing correctly (stock on ECC side) but showing only difference Qunatity from Stock initialization data to date of Query.
we have done all the initial setting at BF11, Process keys and filed setup table for BX abd BF datasources, we are not using UM datasource.
1 we loaded BX data and compressed request (without tick mark at "No Marker Update)
2. initialization BF data and compressed request (with tick mark at "No Marker Update)
3 for deltas we are comperessing request on daily (without tick mark at "No Marker Update).
is this correct process
in as you mentioned for BX no need to compress ( should not compress BX request ? )
and do we need to compress delta requets ?
we have issue for historial data validation,
here is the example:
we have initilaized on may 5th 2009.
we have loaded BX data from 2007 (historical data)
for data when we see the data on january 1st 2007, on BI side it is showing value in negative sign.
on ECC it is showing different value.
for example ECC Stock on january 1st 2007 : 1500 KG
stock on Initialization may 5th 2009 : 2200 KG
on BI side it is showing as: - 700 KG
2200 - (-700) = 1500 ,
but on BI side it is not showing as 1500 KG.
(it is showing values in negative with refence to initialization stock)
can you please tell, is this the process is correct, or we did worng in data loading.
in validity table (L table) 2 records are there with SID values 0 and -1, is this correct
thanks in advance.
Regards,
Daya Sagar

Hi Anil,
Thanks for your reply.
1. You have performed the initialization on 15th May 2009.
yes
2. For the data after the stock initialization, I believe that you have either performed a full load from BF data source for the data 16th May 2009 onwards or you have not loaded any data after 15th May 2009.
for BF after stock initialization delta data, this compressed with marker update option unchecked.
If this is the case, then I think you need to
1. Load the data on 15th May (from BF data source) separately.
do you mean BF ( Material movements) 15th May data to be compressed with No Marker Update option unchecked. which we do for BX datasource ?
2. Compress it with the No Marker Update option unchecked.
3. Check the report for data on 1st Jan 2007 after this. If this is correct, then all the history data will also be correct.
After this you can perform a full load till date
here till date means May 15 th not included ?
for the data after stock initialization and then start the delta process. The data after the stock initialization(after 15th May 2009) should also be correct.
can you please clarify these doubts?
Thanks

How to initialize data?

There is a legacy Java application that has to be migrated into portal. As a first step of this process the application has to be split into 3 portlets. All of them are going to be part of the same home page of community.
This legacy application has initialization process that supposed to be executed when user login into the portal and render home page for community. As result of initialization process some data (Java objects) will be stored in remote http session. All portlets belong the same WAR file so there is no problem to share this data between all of them.
As I understand when portal render the page these portlets will be call asynchronous. So every portlet who needs this initialization data is responsible to check session and initialize them if these data are not there. Because the rest of the portlets also need this data it will introduce locking/unlocking mechanism for this http session object.
So my question is: does portal has any way to help solve this issue or this one is entire application responsibility?
Originally I was thinking that PEI may help somehow but it doesn't look like this.
Any ideas?
Thank you.
Edited by Bryazgin at 04/30/2007 9:04 AM

What is your question? You need them to go in order one at
a time?I guess my question was how to have initialization data in remote http session (shared over 3 different portlets) BEFORE portal begins render a page and actually make calls to remote server?
"Go in order" may be one of the solution, but I don't think Aqualogic supports this functionality, and there is no really needs for this because, imho, this approach kind of against of Aqualogic architecture.
"Delay" is pretty much the some as locking/unlocking in sense that implementation has to be done on application level (I don't see any options to introduce delay through portal Web Service UI).

Require name and date before printing form

I have a 13 page PDF that a customer or our staff prints from our website. Often the customer or staff does not name and date each page of the form. Not having a name and date on each page of the form causes problems when they customer returns the form to the office, and the form pack gets divided for scanning into different areas of the customer file. 1) Is there an Adobe product that changes a PDF to require the downloader of the form to place a first and last name in the name field before printing. 2) Also, I would need a date stamp placed on the form when it prints. Is there I product that could help me program this PDF to do these 2 things? This post is the first time I can recall posting in this community. Any other suggestions are welcome. Thank you.

>> 1) Is there an Adobe product that changes a PDF to require the downloader of the form to place a first and last name in the name field before printing.
Many fields have a "Required" property. This is used when a form is submitted to a scripted web page for processing to throw an error message if any required fields are not completed.
One can use this property within a an action for a form to check if required fields are competed.
>> 2) Also, I would need a date stamp placed on the form when it prints.
I would add a form field that is filled in with the print date and time by some JavaScript in the Will Print action.

Jsf page not rendering in Jdeveloper

Hello. I am using jdeveloper 11.1.2.2. I was working on an application this evening, and added a new jsff page. When I opened the page, I got the "waiting for designer to render" then it stopped, and all I see is white.
I am able to add components to the page via the structure window, but I cannot see what the form looks like in the design view. The the problem started hitting the other jspx form I have in the application.
I read somewhere about someone having the same problem and I tried renaming the windowinglayout.xml, and re-opened jdeveloper, but it did not solve the problem.
This has happened before. I wiped out the system directory, and that works, but wiping out the system directory is painful. Are there any intelligent solutions?
Thank you,
Stuart

I tried renaming the system directory, opening jdeveloper, opening the jsf page -- it rendered. So I then went to the system directory and found the windowinglayout.xml and backed it up.
then I deleted out the new system directory, and the renamed back the old system directory. Found the windowinglayout.xml and replaced it with the good file.
Opened Jdeveloper and the jsf page. Did some work and soon the render failed again.
I am not sure if this is relevant...but the log shows this:

Initialize ITEMs on page render

I have a page that contains several charts that are dependant on two items:
P1_FROM
P1_TO
The charts need these values in order to render. Both Items are date pickers. The problem I have is that when the page first renders, these values are not defined and therefor the chart query returns no results and the charts do not display. Looking at session state I can see that these items have no value assigned to them. In order to get the pages to render I must click on the GO button that I have create on the page. The two items have default values but they do not seem toget assigned until the GO button is pressed.
How can I assign default values to these items so that when the page first renders the charts are displayed, whithout having to press the GO button?

Mike:
I suspect that the chart on page 40 is being rendered by an APEX database connection that is not the same one that renders the rest of the stuff on page 40. So, it is possible that the database connection rendering the chart does not see the new values for the page items set in the URL as these may not have been committed to the database yet.
You could try this.
Change the chart query to be
select 'javascript:setStuff("' || to_char(datum, 'yyyy.mm.dd') || '","' ||to_char(datum, 'yyyy') || '")' link,
to_char(datum, 'dd.mm.yyyy') Datum,
Avg_mips
from ... some sql query...Add the JS below into the HRML page header<script>
function setStuff(p_date,p_jahr) {
$x('P40_DATE').value=p_date
$x('P40_JAHR').value=p_jahr
doSubmit('XXXX');
</script>Define an 'After Submit...' branch to page 40. Make the branch conditional on Request = 'XXXX'

i want to use this GlobalVarContainer.vars.servername within other movieclip.....so i m taking global variable but it is also not working.
this i m using in other movieclip...
var localhost=GlobalVarContainer.vars.servername;
var prjectName=GlobalVarContainer.vars.projectname;

trace("hi");
navigateToURL(new URLRequest("http://"+localhost+":8080/"+prjectName+"/web/vertical45.jsp?page=1"), "_self");
and this i cant put in COMPLETE event handler function bcoz this compare_btn code is in three frame.
plz advise.

Is it possible in a before-page-submit dynamic action to cancel processing?

I have a page where when the user submits, I check certain conditions and prompt the user with a confirmation ("are you really sure you want to submit this...?") and if they press OK (javascript true) continue to submit as normal, else (javascript false) the page should stop submitting.
I know I can do this by putting Javascript code on whatever buttons I need to such that they're prompted from whatever appropriate button but I then thought it might be more elegant to just put it in one place in a before-page-submit DA.
So I figured that in my DA for a before-page-submit I'd try explicitly returning true or false thinking that I returned true it would continue to submit but if false it would stop submitting. Unfortunately no dice.
Example:
Dynamic Action
Before Page Submit
Condition (Javascript Expression): (this.data=="SAVE")||(this.data=="MULTI_ROW_DELETE")
var response=checkPbcDml();
alert(response); //for debugging and I do properly get true or false back
if(!response)
return(false);
else
return(true);So I'd like return(false) to stop the submission process (was only guessing that it'd work, and it doesn't). Is there any other javascript command that I could execute to cancel the submission processing?
Yes I know that I really can do this on my buttons and it'll work...
javascript:if(checkPbcDml())apex.confirm(htmldb_delete_message,'DELETE');
javascript:if(checkPbcDml())apex.submit('SAVE');...but was just hoping to do something in the DA as a matter of elegance to put code in one place rather than two places.

Personally, I'd just try to utilise the confirm action - probably achieved by incorporating the checkPbcDml() function into the dynamic action condition, at the sime time you are checking the request value.Aha! That's it.
The "Confirm" DA action's OK/Cancel response is evaluated by the "Before Page Submit" and cancels the processing.
What I did was:
1. Looked at my old function's conditions:
function checkPbcDml()
if (($v('P265_FREEZE_FLAG')=='Y') && ($v('P265_PUR_MFG')=='M'))
return(true);
else
return(confirm("Part Bid Categories information will only be saved from this page for frozen &F182_MAKE_TEXT. parts.\nDo you want to continue with this action anyway?"));
}2. Appended them to the existing DA conditions that were evaluating the save or multi-row-delete request:
((this.data=="SAVE")||(this.data=="MULTI_ROW_DELETE")) && (!(($v('P265_FREEZE_FLAG')=='Y') && ($v('P265_PUR_MFG')=='M')))3. And created a Confirm action with that message text and removed my checkPbcDml() function.

Ensure List/Menu populate my update form with the correct data before update

Hello,
Please how do I ensure my update form is populated with the correct data before update?
On my update page I have text fields and select fields (dynamic list/menu). When I open my profile page to make updates, I see the field well positioned in the text fields but in the select list/menu fields, I see "Select from list" instead of the value that was initiated selected
Correct Values before update
Wrong values during update
As you can see from the images below, when I open the update page, the list automatically populate the select fields with the last values in the list instead of the Initial values that where selected by the user before the update.
Can anyone please review and let me know where I have gone wrong.
Thank you
Mike

Hello All,
Once more thank you. I have sorted the issue out.
I observed that I was selecting the wrong field. I selected the field matching the record set of the select instead of the field matching the record set of the table I am working as seen on the image belew
I was selecting this - This is the record set of the table that hold values for the city select list
Instead of this. This is the record set of the table behind the form I am working on
My issue is now re-solved.

The clock is set to a date before 1 Jan 2008 and some applications may behave erratically.

hi. this afternoon. I accidently set my time to 1987.
then after awhile. I cant borswer any website. then I try to open app store. And it is all white pages.
but all my sofeware are still working.
then i reastar my Imac. it shows "your clock is set to a date before Jan1. 2008"
okay. And I was going to change it.
but it dosnt let me.
I opened the setting. but it just shows loading date & time forever.
i had wait for a hour already. still show like that.
thx. i really need help. what can i do . it drives me crazy ...

If you can launch Terminal (found in /Applications/Utilities) you should be able to run the date command. For example, if you do this now, you could run:
sudo date 011120462014
That should set your time to January (01) 11 (11) 8 (20):46 p.m. 2014.

Computer Clock set to date before Jan 1 2008

I woke up this morning to find my iMac (less than a year old) showing a message "Your computer clock is set to a date before Jan. 1, 2008..." Also, there were other pop-up windows on the screen saying "krb5kdc", "configd", etc. were not responding or something and that it may cause applications to behave eratically. The computer worked fine yesterday up until bedtime. No power surges, no new installations or anything. Also, I did a virus scan that came up clean. I had to manually set the date and time. Oh, and now it won't recognize my home network and I shut the entire network down and restarted it but the iMac still won't recognize the network even though the checkbox to remember the password is checked every time. Once I get to Safari, it won't connect to internet yet shows full connection. And I clicked to open the Pages program and it took about 5 minutes to start up. Any ideas what has happened??

Exact same thing happened to my MacBook air, except the date was march 24th 2001. I've tried everything with the network including base station resets, manual ip config, repairing permissions etc. Nothing works. I agree the solution is probably to reinstall the os and restore from time machine but that poses a problem with the air since I need a wireless network to access the remote disc feature, unless I can find a SuperDrive. If anyone thinks of an alternative solution please let me know.

After I install itunes my windows 7 - 64 bit machine will not boot and I have to use Restore to boot with a date before I installed itunes

After I install itunes on my windows 7 - 64 bit machine it will not reboot and I need to restore to a date before itunes was install. How do I fix this?

I'm having a very similar issue, paired with iTunes not being able to get online.
iTunes shows up in processes and then hangs at 17,000 K or so -- sometimes it will start up, but that (if it occurs) is a delay of literal hours.
Pretty meticulously went through all the 'cannot connect' trouble shooting, and have uninstalled, restarted, and then reinstalled every piece of apple software; issue is just as firm. Starting in safe mode or admin mode don't fix it; signing in as a different user doesn't fix it.
