Filter vo criteria on page load

i have a requirement where i have to execute a view criteria on a view object when the page is being loaded. page is a master detail page. i have to filter detail view object to display only specific records based on a criteria.
what is the best way to achieve this. i tried using a bean on view BeforePhase which executes a method written on AM, but it is throwing some null pointer exception.

Hi 963798,
in the present taskflow that contains ur page add methodcall as default activity make fixed outcome to ur page, next in method section of method-call (property inspector) bind it to ur managed bean, in managed bean method execute view criteria of your view object, later drag the vo datacontrol on your respective page
in managed bean
urmethod{
oracle.adf.model.BindingContext context = BindingUtils.getBindingContext();
DCBindingContainer bc = (DCBindingContainer)context.getCurrentBindingsEntry();
DCDataControl dc = bc.findDataControl("TestAMDataControl");
ViewObject vo = dc.getApplicationModule().findViewObject("ur VO");
apply ur criteria and execute
example of method-call default activity

Named Criteria for Table Not Filtering on Page Load

Hi Guys and Gals,
I'm tying to create a filtered table using named view criteria (http://docs.oracle.com/cd/E24382_01/web.1112/e16182/web_search_bc.htm#BABBCHIH).
I create the Named Criteria; I drag from the Named Criteria from the Data Control onto the page; I select ADF Read-Only Filtered Table option. I run the page and much to my chagrin, the table is not filtered. A table with all results, plus a filter box with a value "S" (my named criteria filter value), is displayed.
Shouldn't the results already be filtered upon page load?
The filter works correctly when I run tests in my AppModule.
Using JDev 11.1.2.1.0.

I've found a workaround.
I drag and drop the VO (unfiltered) from the Data Control and select read-only table. In my pageDef, I select the table's binding and check the "Enable Filtering" box. I then select the attribute to filter on and the applicable filter text.
The table then displays filtered results on page load.
However, I only see this working for very simple filtering (i.e. one column with simple filter requirements). It should be nice to know why dragging and dropping Named View Criteria onto the page does not automatically filter table results on page load.

Looking for hook into a mb method on page load of jsff with auto query on view criteria.

Hello,
I have a View Criteria that is set to Query Automatically (showing data to match today's date). The target table has a detail table and there is a control that shows parsed XML from the current row in the detail table into a table that I build dynamically. The main table and the detail table show the proper data on page load but the table for the parsed XML is empty. The dynamic table is bound to a managed bean where the parsing is done and data is created. I have the control refreshing properly on a row change of the main and detail tables and on a queryListener for the view criteria.
This is for a jsff page. I have been trying a bunch of approaches with no success. The detail table has a ppr to the main table and the query. I am looking some event on either the query, the main table or the detail table where I can make a call to my managed bean to parse the XML, build the table and refresh the control. I have an attribute binding to the XML data (when I placed it in a control as plane XML it refreshed properly). I only need this on initial page load or first time the tables are populated, I have the other use cases covered.
Running JDev 11.1.2.4
Thank you
Rudy

ok but where?
i have read a topic about "setRefreshOption", but i need a component to execute it.
i have read a topic about a false criteria (1=2), and when i want search, i remove it, but again, i need a component to execute it.
i have read a topic about ${adfFacesContext.postback == true} to write into iterator proeprty, but i haven't this view into my appmodule.
i'm really sorry, but please, can you explain me a little ?

I'm using Firefox 3.6.23 on my windows 2000 and lately i've been having issues with web pages loading and need help figuring out why.

Some of the issues : '''1'''. Page loads blank showing web address in tab. Try reloading usually with no results.(problem have the most!) '''2'''. Message appears "problem loading page, server not found" (diff times & diff websites). '''3.''' Pg with msg "oops link broke, DNS error, server not found" then lists suggested links to sites for fix though all links connect to site IGEARED.COM. (new issue) I don't know what to do please help me identify and fix my issue(s) in english, kind of a newbie : ). thx

Try this.
Type in the address bar about:config.
Accept the warning.
In the page that appears, in the Filter box, type network.http.max-connections. Change the value to 32 (which is probably set to 256 in your case).
Close that page. Restart the browser.

How can I prevent pages loading twice?

Practically every time I click on a link in an email (Outlook 2007) Firefox 3.6.6. loads the page, displays "stopped" and then reloads it, leaving two tabs with the same title.
When I looked for a solution in this forum, searching for "firefox loads pages twice" I got 514 results filling 52 pages, but I soon discovered that though various versions of the question had been asked, there appeared to be no answer, and some replies got into technicalities that were beyond the average user of firefox.
So I raise two points:
1 Can we have a better filter in the forums that does not list every individual hit on a word in the query, but only on the complete phrase (putting it in quotes did not help)?
2. Has a solution been found yet?
== URL of affected sites ==
http://

What is the point of this forum if over 500 people have a problem with pages loading twice, but nobody, neither volunteers nor someone from Mozilla, can provide a solution?
Perhaps it is time to switch to Opera.

Execute search programatically during initial page load.

hi,
when the page is initially rendered, i have requirement to have the page automatically retrieve rows that belong to the user (ie execute a search programatically)
to achieve that i did the following -
1. created search page using autocustomizationcriteria
2. mapped all search fields to corresponding VO fields ( i intend to not override the default where clause since all my search can directly be mapped to a VO attribute)
3.populated the userlogin value into the corresponding search field as follows -
String lg = pageContext.getUserName();
OAMessageLovInputBean lovBean = (OAMessageLovInputBean)webBean.findChildRecursive("searchLogin"); //the searchfield is a messageLOVInput
lovBean.setValue(pageContext, lg);
the behavior i was expecting is for the page to automatically generate the where clause since i populated the search field that is mapped to the VO attribute and execute the query (i did not invoke executequery() per dev guide) BUT instead it is executing a BLIND query with no where clause.
would appreciate any insight into what i am doing wrong....
thank you.

hi, i had initially done the setting of the whereclause and executing programatically. however, when you do that, subsequently, the 'Go' button also needs to be handled programatically (including all search criteria whereclause generation) and then you loose all the features of the queryBean especially the different search options (eg like , starts with etc) on the Advanced Panel unless you code for all those features yourself...... NOTE - the need to handle the 'Go' button yourself happens even though after executeQuery() for just the initial page load, i reset the whereclause and whereclauseparams to NULL....
i also do not have a formvalue associated with the searchlogin field.
any other inputs please ?
thank you.

Getting Page Load Error while opening a Opportunity in new window

Hi All,
outbound SSO is enabled.
when i try to punch-in to my application from CRM through opportunity web link with Web Link Target as "open in custom tab" its working properly, but when i have Web Link Target as "open in new window" i am getting page load error. previously with out Outbounf SSO it is working properly.
Do i need enable any settings in CRM
thanks

when the web link target is "open in new window" or "open in current window" the request send to third party application from CRM ONDemand is HTTPS request as SSL is not enabled it is giving "page load error"(In the web link we are specifying http only) (User athentication type is "username & password/ SSO")
Is there any setting in CRM Ondemand to send Http request only instead of HTTPS?

I want to writte C# code for 503 Service Unavailable error to web application page immediate close connection any page loaded

Here is a ticket regarding our current client web application ( Image data add, edit , delete in folder with form data in MSSQL Database) that using code c#, web form, ajax, VS2008, MSSQL Server2008 , it appears that there is an error where the HTTP
503 error occurs.
. Below is a conversation with Host Server support assistant.Can you take a look at it?
Ben (support) - Hi
Customer - We're having an issue with our windows host
Ben (support) - What's the issue?
Customer - 503 errors
Ben (support) - I am not getting any 503 errors on your site, is there a specific url to duplicate the error?
Customer - no, it comes and goes without any change Customer - could you have access to any logs ?
Ben (support) - Error logs are only available on Linux shared hosting, however with this error it may be related to you reaching your concurrent connections
Ben (support) - You can review more about this at the link \
Customer - probably yes - how can we troubleshoot ?
Ben (support) - http://support.godaddy.com/help/article/3206/how-many-visitors-can-view-my-site-at-once
Ben (support) - This is something you need to review your code and databases to make sure they are closing the connections in a timely manner
Customer - we're low traffic, this is an image DB to show our product details to our customers
Customer - ahhhh, so we could have straying sessions ?
Ben (support) - Correct Customer - any way you could check if it's the case ?
Customer - because it was working previously
Ben (support) - We already know that's the case as you stated the 503 errors don't happen all the time if it were issue on the server the the 503 would stay.
Customer - so our 2/3 max concurrent users can max out the 200 sessions
Customer - correct ?
Customer - is there a timeout ?
Ben (support) - no that's not a time out concurrent connections are a little different then sessions and or connections. Lets say for an example you have 5 images on your site and 5 7 users come to your site this is not 7 concurrent connections but 35. They
do close after awhile hence why the 503 error comes and goes. You can have these connections close sooner using code but this is something you have to research using your favorite search engine
Customer - thank you so much
Customer - I'm surprised that this just started a few weeks ago when we haven't changed anything for months
Customer - any changes from your side ? lowering of the value maybe ?
Customer - I'm trying to understand what I can report as a significant change
Ben (support) - We haven't touched that limit in years
Ben (support) - This could just be more users to your site than normal or even more images
Customer - I was thinking that could be it indeed
Customer - so I need to research how to quickly close connections when not needed
Ben (support) - Correctly
Ben (support) - correct
Customer - thanks !!
Ben (support) - Your welcome
Analysis :
The link provided tells us : All Plesk accounts are limited to 200 simultaneous visitors.
From what Ben (support) says and a little extra research, if those aren't visitors but connections then it's quite easy to max out, especially if the connections aren't closed when finished using. I'd suggest forwarding this to Kasem to see what he thinks.
Cheers,
Customer

Hi Md,
Thank you for posting in the MSDN forum.
>>
I want to writte C# code for 503 Service Unavailable error to web application page immediate close connection any page loaded.
Since
Visual Studio General Forum which discuss VS IDE issue, I am afraid that you post the issue in an incorrect forum.
To help you find the correct forum, would you mind letting us know more information about this issue? Which kind of web app you develop using C# language? Is it an ASP.NET Web Application?
If yes, I suggest you could post the issue directly on
ASP.NET forum, it would better support your issue.
Thanks for your understanding.

After updating to the latest version of Firefox on my Mac there is no progress bar for the page load. I really miss this feature and can't seem to find a way to obtain it.

The page load progress bar that was on the lower right of the window is no longer there. After updating to the latest version of Firefox on my Mac there is no progress bar for the page load. I really miss this feature and can't seem to find a way to obtain it. The tab has a circular progress wheel but this is useless for determining a stuck or slow loading page.
PLEASE NOTE: I am typing this in from a Windows based work computer but am asking about my Apple MacBook Pro that i use at home.

Firefox 4 saves the previous session automatically, so there is no longer need for the dialog asking if you want to save the current session. 
You can use "Firefox > History > Restore Previous Session" to get the previous session at any time. 
There is also a "Restore Previous Session" button on the default about:home Home page. 
Another possibility is to use:
* [http://kb.mozillazine.org/Menu_differences Firefox (Tools) > Options] > General > Startup: "When Firefox Starts": "Show my windows and tabs from last time"

No data found in report csv or pdf output on first page load

No data found in report csv output on first page load. Report shows up on page, but no data found in csv or pdf output. I always need to submit the page and then it shows data in downloads. The page contains a form (read-only) with a report that references 4 page items by using something like the following:
and b.employee_no = v('P5_EMPLOYEE_NO')
and c.fisc_year_pk = v('P5_FISC_YEAR_PK')
and b.job_class = v('P5_JOB_CLASS')
and b.organization = v('P5_ORGANIZATION')
Again, report in the page shows up except there is no data in downloads. Can anyone help me solve this problem? I'm running Oracle APEX 4.2.1 in Oracle database 11gR2.
Thanks.

Sounds like a classic session state issue.
You need to populate you page items using page rendering computations to ensure they're set to session state.
Or if the download is triggered from a button press, you need to ensure those page items are submitted to session state, perhaps via a PL/SQL action.

ADF ProcessScope -- I get a new AdfFacesContext on each page load

I am trying to store some variables in the ADF processScope. But the next time the page is loaded and calls the managed bean methods, the AdfFacesContext is different, and so the processScope is empty. The managed bean is session scope, and I am setting the processScope variables in the bean's Java code.
In particular this happens when I click on the af:table pagination links, e.g. the "next 25".
How can I get access to the same AdfFacesContext (and therefore the same processScope) the next time the page loads and calls the managed bean?
I am using JDeveloper 10.1.3.3.0.
Here is the example code, and the output that is produced from my System.out.println statements:
========== Controller.java (session scope managed bean) ===============

private static int counter;

// initialize list with Map objects

Map map = new HashMap();
map.put("A","first column");
map.put("B", "row " + i);

As you can see above, the AdfFacesContextImpl object has changed, so I have lost the ProcessScopeMap.

Thanks for the idea, Murph.
I didn't need a session scope bean, request would be fine, I just was trying to make something work that would allow me access to the process scope attributes. I want to allow multiple browser windows searching on different objects independently, so I don't want to use session scope.
I tried removing the variable declaration and setting/getting the processScope attribute in the setter/getter methods, to make the process scope attributes independent of the managed bean. But each time the page loads (by clicking the table navigation links), I still lose the process scope attributes. I tried with both session and request scope beans. Either way, in the getLoad() method, when I try to get the label from the process scope (using the new version of getLabel()), it is null.
So the root problem is still there.
For continued discussion on this more specific problem, see my separate thread "JSF ProcessScope attribute missing on page reload from af:table pagination"
at JSF ProcessScope attribute missing on page reload from af:table pagination

Firefox crashes as soon as the page loads it is completely unusable

i got a update prompt from firefox a few hours ago which i installed and now it wont work as soon as the page loads it crashes it wont even stay on long enough to figure out the problem i swear by firefox i have used its for years and never had any problems with it ever if i recall but lately it has been freezing and crashing often i feel like i am using internet explorer and thats bad but now i cant get it to work at all and am forced to downgrade to a lesser program WHAT IS GOING ON????? as for crash ids and troubleshooting info none of that even comes up

Do a clean (re)install:
* Download a fresh Firefox copy and save the file to the desktop.
* http://www.mozilla.com/firefox/all.html
* Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
* Don't remove personal data if you uninstall the current version.
* It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
* It may not be necessary to create a new profile, so first try if it works with your current profile and if not then create a new profile.
Your bookmarks and other profile data are stored elsewhere (not in the Firefox program folder) and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.
