Variable Iterator Refresh Problem

Hi,
I have two method in application module that I dropped on a jspx page as two buttons and the method returns as af:outputtext on that page. When I press one of the buttons to invoke the related method, it clears the result of the other method. Both outputtexts are binded to same variable iterator on the binding site. There seems no relation between these two outputtexts other than being binded to same variable iterator. So why invoking one method clears the result of the other method? Is variable iterator is refreshed everytime a method is invoked? Any help is appreciated.
Best Regards,
Salim

Hi,
the variable iterator is refreshed as a whole. The binding container is in request scope, which also guarantees that the iterator survives. So the work around is to execute both of the methods from a single button

Re-intializing a .JSPX pagedef variable iterator value?

I am using ExecuteWithParams operation to create an ADF parameter (search) form on a .jspx page. By default, the attributes reference a variable iterator which are stored in the request scope (see excerpt from developer's guide below). I can save the inputvalue from the parameter form to a processScope variable by using a setActionListener that is fired when the user presses the commandButton. However, how can I re-intialize the inuptvalue on the search form (using the value saved to the processScope variable) when the .jspx page is re-loaded?
-------------- code snippets --------------------------------------
// search.jspx page - inputvalue on search form
<af:inputText value="#{bindings.keywords.inputValue}"
label="#{bindings.keywords.label}">
<af:validator binding="#{bindings.keywords.validator}"/>
</af:inputText>
// search.jspx page - setActionListener to save inputValue to processScope
af:commandButton actionListener="#{bindings.FindMethod.execute}"
text="Search">
<af:setActionListener from="#{bindings.keywords.inputValue}"
to="#{processScope.keywords}"/>
</af:commandButton>
// searchPageDef.xml - variable iterator used to store variables for ADF parameter form
<executables>...........
<variableIterator id="variables">
<variable Type="java.lang.String" Name="FindMethod_keywords"
IsQueriable="false"/>
</variableIterator>
<bindings>......
<methodAction id="FindMethod" MethodName="FindMethod
RequiresUpdateModel="true" Action="999"
DataControl="SearchServiceDataControl"
InstanceName="SearchServiceDataControl.dataProvider">
<NamedData NDName="keywords" NDType="java.lang.String"
NDValue="${bindings.FindMethod_keywords}"/>
</methodAction>
<attributeValues id="keywords" IterBinding="variables">
<AttrNames>
<Item Value="FindMethod_keywords"/>
</AttrNames>
</attributeValues>
-------------excerpt for developer's guide ------------------------------------------------------
Because you dropped the ExecuteWithParams operation, the attributes reference a
variable iterator that accesses the variables instead of a collections iterator. This is
because the operation (unlike the returned collection) does not need to access an
instance of an object; therefore, there is nothing to hold the values entered on the page.
Variables act as these data holders.
JDeveloper creates a variable for each named bind variable. The variables are declared
as children to the variable iterator, and are local, meaning they live only during a
single request, and while they are carried across subsequent post-backs to the same
form, they would be forgotten (and re-initialized) when a user navigates to some other
page.

Receive an answer to a difficult JDev question = Excellent.
Get working example code to solve your problem = Priceless.
Thanks for the reply, er, I mean code sample! This does the trick and was what I was looking for.
However, it does seem to have a side effect that has created another issue that I posted in a separate thread:
af:inputText value fields refreshed when a backing bean is used for value?

Lov iterator refresh issue

HI friends!
I'm using JDeveloper 11g
I've got a problem with a lov attribute in my application.
I need to implement the following scenario:
I have an adf table Licence in my jsf page. One of the table columns includes a lov attribute which values must be selected from a list box (a list data source is LicenceProducer lov view object).
If there is no required licence producer in the drop down list we can trigger a pop up dilaog (kind of lov dialog) and create a new one row in the data source iterator.
Then the required attribute value of the newly created row must be passed to the list in the source jsf page and become a currently selected value for the lov attribute of the Licence VO.
SO i've have implemented almost the whole scenario:
1. created an appropriate lov attribute in Licence VO with LicenceProducer VO as a list data source
2. created a bounded adf task flow which is resonsible for displaying the pop up lov dialog with all insert/commit/return new value functionallity.
Everything works just greate except that the lov iterator is never refreshed after returning from the pop up dialog.
The updated content of the list box is only seen after reloading the source jsf page. Setting partial page rendering (for the Licence adf table) on returning from the pop up dialog does't work.
I saw a number of posts on this issue but never found any good solutions.
I think that i must somehow get an access to the lov iterator (data source vo) wich is not the same as the base LicenceProducer view object and refresh it programmatically.
PS. if i brought my issue in a not sufficiently clear way. please answer the quite simplier question. Is it possible somehow to add a lov functionallity with the possibility to add new rows into lov iterator?
Thanks in advance. Alex.

Thanks friends.
It is so greate to see somebody notice your question and even have the similar problem.
First to Paul
1. Yes I have a model driven LOV, i.e. i defined the lov functionalty for the attribute in a VO.
2. I'm using JDeveloper 11g as you might be using.
3. Actually i'm afraid i have not fully understood your approach with a row impl class. AS i could notice there were no worthy changes added into the row impl class after i had redefined VO's attribute to use a lov view object.
it would be greatly appreciated if you let me know more detail about your solution.
By the way i have noticed one interesting thing as I was experimenting with my issue. It turned out that the lov iterator refreshes just excellent on returning from a pop up "manually created lov dialog" after i click a rollback button of the data control
where the VO iterator containing the attribute with the lov functionalty exists. Give it a try and you'll see, no other standard operation button gives the same effect!!!!! I realized it accidentially myself.
To Hasim
if i understand you right your assumption is to refresh a row iterator which is the basis for the lov attribute and then refresh a page element where the lov attribute has been dropped?
If so than i've tried it because this is the first thing comes into mind. But it doesn't work, i think that this basis iterator we select for the list of values of the required attribute in VO is not the same as a real list Datasource iterator...
If i understood you wrong please give me know and explain please your approach. Your opinion is interesting for me.
I address our experts ones again with a rather simplier question. Is it possible to create a model driven lov attribute where it would be possible to insert new rows into the list of values during the ongoing user session?
Alex.

DataGrid Refreshing Problem

Hi All,
First let me explain my problem clearly.I am facing the
problem with refreshing datagrid for add,update,delete operations.
For adding task(todo app) i am using another mxml
component(PopUpwindow).when i do add,delete or update, changes are
happening
in database pakka and fine.There is no error in that.Only
problem is when i add or delete or update a task, datagrid has to
get refresh with the updated or new data.Then only from ui
user will know that he added a task or deleted a task etc right.
sometimes it's refreshing fine and sometimes not.If it
doesn't refresh at all times i can think of my logic.But if it's
happening sometimes and sometimes not.
after add or delete or update am using below 5 lines of code
to refresh datagrid.
getList.send(); //sending request again to load new data
using httpservice.
datagrid.dataProvider = resultList; //resultList is
bindabale ArrayCollection variable.
resultList.refresh(); //this line not all giving any
changes.i think it's not working
datagrid.validateDisplayList();
datagrid.validateNow();
Thnaks & Regards,
premadas.

Hey harsha,
the following code i'm using for deleting a task.
<mx:HTTPService id="getTodo" url="
http://dev.edinc.in:8080/poc/ToDo/GetToDo.jsp"
result="resultHandler(event)"/>
private function delTask():void
delTodo.cancel();
delTodo.send(delData);
getTodo.send();
deltaskname.text = "";
deltaskdate.selectedDate = new Date();
deltaskcategory.selectedIndex = -1;
deltaskpriority.selectedIndex = -1;
deltaskstatus.selectedIndex = -1;
Anything i need to apply here.
Thanks & Regards,
Premdas.

12C - No context menu in the variables iterator of pageDef

Hello everyone!!
I'm using jDev 12c and I just noticed that below behavior:
I have a .jsf page and I go to the bindings (pageDef) of the page.
In the variables iterator (Executables column) I right click in order to select "Insert inside variables -> variable" but nothing happens. No context menu appears whatsoever.
So, there's no declarative way to create a variable.
Either the menu is missing on purpose or probably has been omitted accidentally.
Just wanted to mention that...

Hi Timo.
Thanks a lot for your reply.
You are right that I can insert a variable through the structure window (unfortunatelly I hadn't read your article before). This is not a problem.
The other issue remains.
So I create a variable (via the structure window) and then I create an attributeValue pointing to the just created variable. So far so good.
By clicking on other attributeValues, operations, tree bindings etc which reside in the same pageDef, after a few clicks the attributeValue of the variable is pointing to an irrelevant iterator! It's very easy to reproduce.

How to handle Back button, Browser Refresh problem at server side.

Hi Friends,
How to handle Back button, Browser Refresh problem at server side in java?.
I am able to trace that,
request.getHeader("ACCEPT") is returning value- */*
when the browser was refreshed and returning different MIME types
for all other actions from browser.
I have doubt, will the above solution works always for all servers,browsers?.
Please also specify any solution to handle back button at server side?.
Thanks in Advance.
Venkat..

I'm sorry I don't think tht's the right solution for
the above question....
We must be aware that whatever scripting methdologies
we either javascript/vbscript would executed @
client(browser) side not @ server side....
Dud If U get a good solution keep me updated.....
THANKS & REGARDS,
RAHULMy dear friend ...
the bad news is that u simply cant disable or add any listener to the back button of the browser.
When u hit the back button of ur browser the URL gets re-executed. So in case u have a JSP then the history.forward() is the best solution. [only if the page doesnt get expired similar to secure https sites]
Now dont say that user can have javascript disabled ...those users will have a pretty touch time browsing websites since javascripts r used extensively by almost all websites.
But in case u have an action.do or servlet call then u need to manage it using a session variable since the request will be sent to the server rather than client.
For multiple form submittion issues read the following article in javaworld...
Client vs. server solutions
Different solutions can solve this multiple form submission situation. Some transactional sites simply warn the user to wait for a response after submitting and not to submit twice. More sophisticated solutions involve either client scripting or server programming.
In the client-only strategy, a flag is set on the first submission, and, from then on, the submit button is disabled based on this flag. While appropriate in some situations, this strategy is more or less browser dependent and not as dependable as server solutions.
For a server-based solution, the Synchronizer Token pattern (from Core J2EE Patterns) can be applied, which requires minimal contribution from the client side. The basic idea is to set a token in a session variable before returning a transactional page to the client. This page carries the token inside a hidden field. Upon submission, request processing first tests for the presence of a valid token in the request parameter by comparing it with the one registered in the session. If the token is valid, processing can continue normally, otherwise an alternate course of action is taken. After testing, the token resets to null to prevent subsequent submissions until a new token is saved in the session, which must be done at the appropriate time based on the desired application flow of control.
for more details refer :
http://www.javaworld.com/javaworld/javatips/jw-javatip136.html
Hope u got the idea.
FYI I have been using both these ideas in my credit card payment gateway project. This concept has worked really well.

So far all is going well except that my animatate gif keeps refreshing everything the page is refresh.
Is there a way the i can prevent the body of the page from refreshing?
below is my sample code:

Smartview 11.1.2.1.102 Refresh problems

I have multiple users experiencing severe refresh problems after upgrading to smartview version 11.1.2.1.102.
Users state Refresh is taking 10-15mins+ when in old version 9x it only takes 1-2mins. In addition users have rebuilt the excel files (copy in new workbook) then all is working fine but when saved/the next day the refresh goes very slow again!
Please can any help?

1. Deleting the Sheet Info fixes the problem for the moment - but the problem soon returns. Do you know what causes the problem, so we can cut the repeating cycle? Is this strictly a multi-user issue? We do have several users that may use the file. Some have version 11.1.2.1.000 (not 103). Oracle's tips doc (http://www.oracle.com/technetwork/middleware/bi-foundation/epm-tips-issues-73-102-1612164.pdf) mentions uncompressed metadata stored in the worksheet.
2. Is there a specific version that allows the Sheet Info fix? Oracle's tip sheet says they need Some have version 11.1.2.1.103, but the users we have seen so far can use this workaround on Some have version 11.1.2.1.000. I'd like to know when at what version this fix starts so I can push other users to update. It would be good to know at which version this issue starts.
Thank you - great information in the thread!
P.S. for reference:
From http://www.oracle.com/technetwork/middleware/bi-foundation/epm-tips-issues-73-102-1612164.pdf
In EPM System Release 11.1.2.1, I am opening .xls files with Smart View functions in Excel 2010, but it’s very slow or seems to freeze Excel. How can I fix this?
This is most likely due to an issue with uncompressed metadata stored in the workbook. In most cases, the issue can be found in the first sheet in hidden shapes. Note that the file will open but it may take a very long time, and in some cases the file will open fine with Smart View disabled. In other cases it will not matter. To solve this problem, save a copy of the file and follow the steps below for the version of Smart View you have.
If you are using Smart View 11.1.2.1.103 or above, follow these steps:
1 Open the file (this may take a while) with Smart View enabled.
2 From the Smart View Ribbon, select Sheet Info.
3 Select Delete Smart View Info.
4 Select Workbook and all Sheet Info.
174 Miscellaneous and Product-Specific Tips
5 Click OK.
6 Save the modified workbook.
7 Reopen the workbook.
If you are not using Smart View 11.1.2.1.103 or above, follow these steps:
1 Open the file (this may take a while).
2 Right-click on the tab of the first worksheet and select Select All Sheets.
3 Right-click on the tab of the first worksheet and select Move or Copy.
4 In the drop-down box, select (new book) and check Create a Copy.
5 Save the workbook.
6 Open the new workbook.
7 Refresh the data.

How do you save a Waveform Graph as an X Y chart + be able to save the coordinates at a variable iteration?

I am trying to do this with an O-Scope VI, and I am very new at LabVIEW, so please excuse any errors, or obvious questions.

Hi Nick,
Which specific VI or set of VIs are you using to get this data? In order to put data in an XY Graph you will need to put together a cluster of your X and Y data and feed it to the XY Graph. You prepare the cluster by developing an array of X coordinates and an array of Y coordinates and bundling them (Using a Bundle function) into a cluster.
By variable iteration do you mean an iteration of the user's choice, or a specific iteration count (like every 10th iteration)? Choosing when to load data into the cluster or when to display new data on the XY Graph can be done by using case structures and a button on the front panel. You could also use the iteration [i] terminal of your loop and some math and Boolean logic to choose when to execute certain commands.
Some resources that might help a new user:

Screen refresh problem where data is entered and the screen doesn't refresh

Many people in the company are experiencing the odd screen refresh problem where data is entered and the screen doesn't refresh to show the updated result in corresponding cell formulas.
Microsoft have issued a hotfix to fix the issue for Excel 2003 as shown. Microsoft released a hotfix for this problem (<a href="advisory?ID=978908">KB978908</a>). Display memory tends to pick up data from hidden sheets and pastes it
into the active screen. No impact on the file. This occurs when protecting and unprotecting worksheets in VBA. I also suspect that enabling and disabling screen refresh contributes to this problem. In any case there is a fix, albeit with the following disclaimer:
As of yet I have not been able to find a fix for this for office 2010 and 2013, Any suggestions would be great.

Hi,
Based on your description, Excel does not show the text strings when you typing. It may be caused by the cell format, if we set the cell format as ";;;" in custom format, it will not display the text that you typed.
And the issue may be caused by the third-party input method, there are some compatibility issue between them.
If the issue still exits, please try the following methods
Verify/install the latest updates
Repair your Office program

Screen refresh problem with Windows 7

Hello all,
I've recently begun testing Oracle with Windows 7 on a new HP 2540p notebook computer. I've encountered a very strange issue so far. After logging into Oracle, and Windows switches to Windows Basic theme, I should be taken to the main Navigator screen. But instead, the screen is simply white. If I drag (or nudge) the title bar just a bit, the screen refreshes and I can see the menu items. Then if I click on something (or even use hotkeys - ALT+F to get the file menu, for example), I don't see anything happen. But if I move the window just a bit, the screen refreshes and I can see that it did actually take my input, it just didn't re-draw the screen. I'm wondering if this may be a graphics driver issue (I do have the latest driver for the Intel Graphics Media Accelerator HD adapter), or if someone could point me toward a resolution to this problem. Any help is much appreciated.

Dear All,
Same problem of REFRESH PROBLEM also faced by but only a single and specific Windows 7 client.
if you have resolved the issue , so please share with us.
Thanks

Forms Refresh Problem on The Web??

i have a form coded in 6i. in this form i have around 20 buttons one below another and each of the button has a stacked view associated with it. whenever i click on a button i am opening the relative stacked view on th content canvas and repositioning the rest of the bottons and views by moving them down.
Now the problem is it works fine in client-server, but when i run it on the web, when i try to open any of the buttons the screen scrolls automatically to the top. I also noticed that if i wait for a few seconds(or sometimes minutes) the form takes me to the correct position. i think there is some refresh problem. i tried Syncronize also but to no use.
i would appreciate If someone can help me out on this ASAP. (thanks for the patience in reading this long mail!!)

Try to instal the latest version of Jinitiator. I have similar problems, but my case is not so bad. Jinitiator develops very quickly and as i have heard it works now fine.
