Best practice for conditional region display

I feel like I'm missing something here...
What's the easiest way to control display of a region only if the user has submitted that same page via a button?
For example, I only want to display a search results region if the user has entered search criteria and pressed a "Search" button.
Currently, I'm setting a hidden item value on page submission, and only displaying the region if the hidden item value = "SEARCH".
Is there a better way?

After click the Search button (Item Name = SEARCH),
debug mode shows the following at the start of the SHOW:When you submit the page by clicking the button, the REQUEST will be set to the button name during accept procesing, not during the subsequent show processing (the request value for the latter can be passed in via the same-page branch you have defined)
To verify this, create a dummy after-submit PL/SQL process with NULL; and a Success Message of "Fired", make it conditional upon REQUEST=SEARCH and make sure your branch has the 'Show process success message' checkbox checked.
Now when you click the Search button, the page should re-display with the Fired success message.

What is best practice for conditional rendering?

i have a set of radio buttons that conditionally render another set, which in turn conditionally render a 3rd set.
i am doing this by using a valueChangeListener on an h:selectOneRadio
when i click yes on the 1st set it renders the 2nd set.
when i click yes on the 2nd set it renders the 3rd set.
when i click no on the 1st set now it correctly removes the 2nd & 3rd sets, the method also nulls the values.
when i click yes on the 1st set, it renders the 2nd set with the old values even though they were nulled. and i can see in the debugger they are still null.
so there seems to be an issue updating the model, but i dont know what that issue is. im sure it just has something to do with the way i am trying this conditional render. please see below for my first field and my valueChangeListener method.
any help with what is a best practice for this scenario would be greatly appreciated.

               it.next();
               it.remove();
          this.getFacesContext().renderResponse();
     }i also tried doing this another way by just using an action method attached to the a4j:support tag, but that introduced a different set of issue. so ill leave that out for now unless that is the direction someone would like to direct my issue in.
Thanks in advance

Similar issue is covered and explained here: [http://balusc.blogspot.com/2007/10/populate-child-menus.html]. Not sure if it solves your problem as you're using ajax4jsf whereas I don't, but it might give new insights. To the point you might need to bind the component(s) and use setValue(null) or setSubmittedValue(null).

What is the best practice for changing view states?

I have a component with two Pie Charts that display
percentages at two specific dates (think start and end values).
But, I have three views: Start Value only, End Value only, or show
Both. I am using a ToggleButtonBar to control the display. What is
the best practice for changing this kind of view state? Right now
(since this code was inherited), the view states are changed in an
ActionScript function which sets the visible and includeInLayout
properties on each Pie Chart based on the selectedIndex of the
ToggleButtonBar, but, this just doesn't seem like the best way to
do this - not very dynamic. I'd like to be able to change the state
based on the name of the selectedItem, in case the order of the
ToggleButtons changes, and since I am storing the name of the
selectedItem for future reference.
Would using States be better? If so, what would be the best
way to implement this?
Thanks.

I would stick with non-states, as I have always heard that
states are more for smaller components that need to change under
certain conditions, like a login screen that changes if the user
needs to register.
That said, if the UI of what you are dealing with is not
overly complex, and if it will not become overly complex, maybe
states is the way to go.
Looking at your code, I don't think you'll save much in terms
of lines of code.

Best practice for placing module

Hello
I have an enterprise application project, with :
1) EJB Module
2) Web Module .
I want to add the hibernate jars+classes+data+servlets+utils etc...
Should i create a new Web module for hibernate or should i add it to the existing EJB module which is my business logic ?
What is the best practice for that?
Thanks !

Thanks for the reply, Jiri.
I believe that the answer is 'yes' to both of your questions above. I do have a question about the formatting of the meta tag itself, as my main question is how do I extract the needed information from a particular CDF so that it is displayed in the <head> section located in the page template.
I have a Region Definition for the content section of my page with a 'Title' field, which a contributor can fill in, save, and create a Contributor Data File with their own specified title. Let's also say that my page template, which formats the entire page, looks like this (rough):
<html>
<head>
<title>Web page</title>
</head>
<body>



</body>
</html>
What would my <meta> tag look like for the following:
<meta property="og:title" content="Title of the content section"/>
Let's name our templates/definitions:
Page Template: PT_META
Region Template: RT_META
Region Definition: RD_META
Contributor Data File: CDF_META
In other words, how do I extract the information included in the Contributor Data File (as well as its metadata) for use in the Page Template? Is there some sort of Idoc Script call that can be used?
Thank you so much,
Josh

BEST PRACTICES FOR CREATING DISCOVERER DATABASE CONNECTION -PUBLIC VS. PRIV

I have enabled SSO for Discoverer. So when you browse to http://host:port/discoverer/viewer you get prompted for your SSO
username/password. I have enabled users to create their own private
connections. I log in as portal and created a private connection. I then from
Oracle Portal create a portlet and add a discoverer worksheet using the private
connection that I created as the portal user. This works fine...users access
the portal they can see the worksheet. When they click the analyze link, the
users are prompted to enter a password for the private connection. The
following message is displayed:
The item you are requesting requires you to enter a password. This could occur because this is a private connection or
because the public connection password was invalid. Please enter the correct
password now to continue.
I originally created a public connection...and then follow the same steps from Oracle portal to create the portlet and display the
worksheet. Worksheet is displayed properly from Portal, when users click the
analyze link they are taken to Discoverer Viewer without having to enter a
password. The problem with this is that when a user browses to
http://host:port/discoverer/viewer they enter their SSO information and then
any user with an SSO account can see the public connection...very insecure!
When private connections are used, no connection information is displayed to
SSO users when logging into Discoverer Viewer.
For the very first step, when editing the Worksheet portlet from Portal, I enter the following for Database
Connections:
Publisher: I choose either the private or public connection that I created
Users Logged In: Display same data to all users using connection (Publisher's Connection)
Users Not Logged In: Do no display data
My question is what are the best practices for creating Discoverer Database
Connections.
Is there a way to create a public connection, but not display it in at http://host:port/discoverer/viewer?
Can I restrict access to http://host:port/discoverer/viewer to specific SSO users?
So overall, I want roughly 40 users to have access to my Portal Page Group. I then want to
display portlets with Discoverer worksheets. Certain worksheets I want to have
the ability to display the analyze link. When the SSO user clicks on this they
will be taken to Discoverer Viewer and prompted for no logon information. All
SSO users will see the same data...there is no need to restrict access based on
SSO username...1 database user will be set up in either the public or private
connection.

You can make it happen by creating a private connection for 40 users by capi script and when creating portlet select 2nd option in Users Logged in section. In this the portlet uses there own private connection every time user logs in.
So that it won't ask for password.
Another thing is there is an option of entering password or not in ASC in discoverer section, if your version 10.1.2.2. Let me know if you need more information

Best practice for Spark repeating background image in a SkinnableContainer?

In my old Flex 3.5 code I would accomplish this by dropping an Image into a Canvas and hitting the Canvas with some css style stuff to get the repeat. The Image tag had a source property that would take a web address so I could dynamically grab different images from the web based on some conditions. Little bit more trouble with Flex 4.5 and Spark but I'm trying to get there.
Here Adobe docs explain how to *embed* a background image:
http://help.adobe.com/en_US/flex/using/WS422719A4-7849-4921-AF39-57FF567B483B.html#WS063B0 491-B7AB-4b00-A39F-E44310BCB0E0
They use a BitmapFill object in the skin.

    <s:Rect id="background" left="3" top="3" right="3" bottom="3" alpha=".25">
        <s:fill>
            <s:BitmapFill source="@Embed(source='../../assets/myImage.jpg')"/>
        </s:fill>
    </s:Rect>
Problem is I need to do this without embedding the image. In my old code I grabbed the image from web (set source property on Image tag to web address). What's the best practice for achieving this with a skinnable container? The BitmapFill object used above won't take a web address for a source.
Thanks in advance.

Use BitmapImage with a fillMode of repeat:
<s:BitmapImage source="http://www.google.com/intl/en_com/images/srpr/logo2w.png" width="100%" height="100%" scaleMode="stretch" fillMode="repeat" />

Best practice for "Quantity" field in Asset Master

Hi
I want to know what is the best practice for "Quantity field" in asset master. It should be made displayed only or required field in Asset Master creation.
Initially I made this field as required entry. So user entered 1 quantity. At the time of posting F-90, he again entered quantity. So my quantity in asset master got increased. Hence i decided to make that field display only in asset master creation.
Now i made that field as display only in asset master creation. At the time of posting F-90, that quantity field is not coming only. I check my field status group for posting key as well as GL account. Its optional field. Inspite of that user is able to make entry in F-90. Now quantity field is '0' only in asset master even though there is some value in asset.
Please help what is the best practice wrt quantity field. Should be open in asset master or it should be display only.

Hi:
SAP Standard does not recommend you to update quantity field in asset master data. Just leave the Qty Field Blank , just mention the Unit of Measure as EA. While you post acquisition through F-90 or MIGO this field will get updated in Asset master data automatically. Hope this will help you.

What is the best practice for inserting (unique) rows into a table containing key columns constraint where source may contain duplicate (already existing) rows?

My final data table contains a two key columns unique key constraint. I insert data into this table from a daily capture table (which also contains the two columns that make up the key in the final data table but are not constrained
(not unique) in the daily capture table). I don't want to insert rows from daily capture which already exists in final data table (based on the two key columns). Currently, what I do is to select * into a #temp table from the join
of daily capture and final data tables on these two key columns. Then I delete the rows in the daily capture table which match the #temp table. Then I insert the remaining rows from daily capture into the final data table.
Would it be possible to simplify this process by using an Instead Of trigger in the final table and just insert directly from the daily capture table? How would this look?
What is the best practice for inserting unique (new) rows and ignoring duplicate rows (rows that already exist in both the daily capture and final data tables) in my particular operation?

Please follow basic Netiquette and post the DDL we need to answer this. Follow industry and ANSI/ISO standards in your data. You should follow ISO-11179 rules for naming data elements. You should follow ISO-8601 rules for displaying temporal data. We need
to know the data types, keys and constraints on the table. Avoid dialect in favor of ANSI/ISO Standard SQL. And you need to read and download the PDF for:
https://www.simple-talk.com/books/sql-books/119-sql-code-smells/
>> My final data table contains a two key columns unique key constraint. [unh? one two-column key or two one column keys? Sure wish you posted DDL] I insert data into this table from a daily capture table (which also contains the two columns that make

Then the "capture table" is not a table at all! Remember the fist day of your RDBMS class? A table has to have a key. You need to fix this error. What ETL tool do you use?

Best practice for backing bean population? (also, ActionListener RANT)

Hello,
I am about 3/4 of the way through development of a small to medium size JSF application. Sometimes I really like JSF, but much of the time I am left puzzled or frustrated for hours trying to find workarounds to JSF's bugs/glitches and design flaws.
For example, early on, I was impressed with how easily it was to invoke a method from a page using an actionlistener. Now that I'm actually building things with JSF, the actionlistener funtionality still seems cool, but incredibly half baked. I find myself using request parameters LIKE CRAZY to work around the fact that JSF doesnt support passing parameters directly to backing bean methods. This feels awkward and wrong considering the fact that JSF is intended to abstract the HTTP underpinnings. To add insult to injury, I often have to iterate through ALL of the request parameters looking for one that has an id with an ending matching my desired property name (since JSF appends it's own crap to the beginning). I don't like doing things in a hacky way. This seems very hacky, and I feel dirty doing it.
So, my first question is, what is the best practice for populating backing beans??? How do others accomplish this. I can think of several other approaches, but none feel less hacky.
Second, are there plans in the next spec (please say there are) to allow parameters to be passed to backing bean methods? If not, WHY THE HECK NOT?
Even though JSF expert group people have been conspicuously absent from this forum of late, I'd really appreciate responses from you as well.
Thank you for your thoughts.

Hi BrownBear,
I've been using JSF for about 6 months now and I'd be glade to help as much as I can.
Concerning parameters, I'm not sure what your issue is but I use the f:param tag to pass them. If you could post an example of what you are trying to do, I could see exactly what your issue is. Maybe the f:param can't help you.
As for best practice for populating backing beans, I personaly try to let JSF do as much as possible. For example, if I have a backing bean with five properties, I make sure that they all are on the JSP page the bean serves. If one of the property is just there as an Id like, lets say, a Person ID (DB row key), then I put it on my JSP page as a hidden input field. I do the same with the properties that only for display, if I want them to be back in my bean when request comesback.
Hope this help some how. Please, feel free to ask specific questions related to your specific problem and I monitor this post and trnasfer to you the ;little JSF experience I have.
I'm pretty happy with JSF as it is but it sure needs improvements. :) What the heck, it's version 1.01 after all, and the next release should be a great one with the integration of JSTL.
Cheers

You cannot add agents to skills dynamically; however, you can queue the caller into more than one CSQ based on statistics. You would use the Get Reporting Statistics and an If step within the Queued branch of your first Select Resource step. If the condition is met (e.g. Contacts Waiting >= 10) then exectue a second Select Resource step within the queued branch of the first. The contact would then be waiting in both CSQs waiting for an agent.

Best practices for loading swf's

Greetings,
Using CS5 AS2
I'm creating a website in flash (all the files will be in one directory/folder on SharePoint) and want to make sure that what seems to be working fine is best practice.
I have an index.swf with many buttons which will take the user to landing pages/content/other swfs. On these different buttons I have the script...
on (release) {loadMovieNum("name.swf", 0);} I could also do just {loadMovie("name.swf", 0);} ??
The movie transitions nicely to name.swf and on this page I have a button that returns the user to the index.swf...
on (release) {loadMovieNum("index.swf", 0);} Things move back to index.swf nicely and user can chose to go to another landing page.
It looks like I'm on the right track, bc nothing is going awry? but want to check. Am I following best practices for moving from one swf to another within a website?
Thanks for help or confirmation!!

loading into _level0 (and you should use loadMovieNum, not loadMovie, when loading into a level) undermines some of the benefits of a flash application: all the assets must load with each display change and the user sees a flash instead of appearing to transition seamlessly from one display to the next.

Best practice for linking fields from multiple entity objects

I am currently transitioning from PHP to ADF. I'm looking for the best practice for linking data from multiple entity objects.
Example:
EO 'REQUESTS' has fields: req_id, name, dt, his_stat_id, her_stat_id
EO 'STATUSES' has fields: stat_id, short_txt_descr
'REQUESTS' is linked to EO 'STATUSES' on: STATUSES.stat_id = REQUESTS.his_status_id
'REQUESTS' is also linked to EO 'STATUSES' on: STATUSES.stat_id = REQUESTS.her_status_id
REQUESTS.his_status_id is independent of REQUESTS.her_status_id
When I create a VO for REQUESTS, I want to display: REQUESTS.name, REQUESTS.dt, STATUSES.short_txt_descr (for his_stat_id), STATUS.short_txt_descr (for her_stat_id)
What is the best practice for accomplishing this? It appears I could do it a few different ways:
1. Create the REQUESTS VO with a LOV for his_stat_id and her_stat_id
2. Create the REQUESTS VO with the join to STATUSES performed within the query for the VO. This would require joining on the STATUSES EO twice (his_stat_id, her_stat_id)
3. I just started reading about View Links - would that somehow do what I'm looking for?
I also need to be able to update his_status_id and her_status_id through the by selecting a STATUSES.short_txt_descr from a dropdown.
Any suggestions on how to approach such a stupidly simple task?
Using jDeveloper 11.1.2.2.0 if that makes a difference in the solution.
Thanks ahead of time,
CJ

CJ,
I vote for solution 1 as it's just your use case. As you said you what to update the his_status_id and her_status_id through the by selecting a STATUSES.short_txt_descr by a drop down. This is exactly the LOV solution.
ViewLinks are used fro master detail navigation (which you don't do here) and Joining the data make it difficult to update (and you still need a LOV for the drop down box.

Best Practice for setting bind variable when application loads

I am using JDeveloper 11.1.2.3.

Query Best Practice for Reports

I am new to Apex and I am wondering what is the best practice for store your sql quries for reports. I am a believer of storing all sql behind pacakge functions or procedures. And it looks like the only options for report pages are to use a direct SQL query, or a function that returns a query as a string. Yes the function method counts as putting the code in Oracle but not really. It is still getting compiled and parsed on the Apex side. It would be nice if Apex could handle a cursor but I have read that it doesn't directly. You have to have a function that returns a cursor and then create a pipelined function that calls the cursor function. That is kind of silly. Is there some other way to do this?
Apex 4.2
Oracle 11.2.0.2
Thanks for any input.
Jeff

Hi Jeff,
I'm not necessarily a believer in packaging queries. I'm a little more pragmatic in that I believe it may make sense in environments where you have a client environment that just expects a result set that is then manipulated by the client for the purposes of presentation, pagination etc. Apex has a different architecture in that the client is purely an HTML presentation layer (browser) and the presentation, pagination etc is formulated in the database along with the data using the Oracle web toolkit, which is a set of internal packages that produce HTML. Note that handling and manipulating ref cursors inside PL/SQL is not a joy, they were mainly designed to be passed out to external clients. (Often to shield programmers who don't or won't even try to understand relational concepts)
This means that when you create a report based on a query, the Apex engine will manipulate that base query, depending on the display requirements and pagination requirements of your report, before it submits that query to the database for execution. To get an idea of how this manipulation occurs, you can run your report in debug mode and check the actual query that is submitted to the database. If the query is presented as an already executed ref cursor, then the Apex engine can't execute in the way that it does. As you have already found out, the only way of using packaged queries returning ref cursors is by the use of a pipelined function, so that the Apex engine can treat the result as a normal query.
This is the architecture of Apex, and I suspect that re-engineering the Apex engine to handle ref cursors natively, as opposed to using a pipelining trick, would be a considerable change. I hope this at least helps to explain why ref cursors and Apex don't mix. I personally don't see the purpose of having an abstraction layer of packaged queries below an abstraction layer of an API such as Apex. SQL is a perfectly good API.
