Does setSelectionPath() method of JTree calls the treeValueChanged() method

Hello,
Just wanted to know whether setSelectionPath() method of JTree calls the treeValueChanged() method after selecting the path?
Thanks.

JSP does not call the right method in controller class

Hi all,
I have a jsp file which loads a page at this address: http://localhost:8080/dir/list/
I've added two checkboxes to the page; user can check both checkboxes, only one or none. Following is code I have in jsp file:
<form class="checkboxForm">
<c:choose>
<c:when test='${newItems==true}'>
<input id="newItems" type="checkbox" value="#" name="newItems" class="checkbox2" checked="checked" /><strong> New Businesses   </strong>
</c:when>
<c:otherwise>
<input id="newItems" type="checkbox" value="#" name="newItems" class="checkbox2"/><strong> New Businesses   </strong>
</c:otherwise>
</c:choose>
<c:choose>
<c:when test='${rejectedItems==true}'>
<input id="rejectedItems" type="checkbox" value="#" name="rejectedItems" class="checkbox3" checked="checked"/><strong> Rejected Businesses   </strong>
</c:when>
<c:otherwise>
<input id="rejectedItems" type="checkbox" value="#" name="rejectedItems" class="checkbox3"/><strong> Rejected Businesses   </strong>
</c:otherwise>
</c:choose>
<a href="#" onclick="apply();">
<button name="apply" class="btn-primary" value="Apply" tabindex="4">Apply</button>
</a>
</form>
<script type="text/javascript">
function apply(){
     var newItems = document.getElementById("newItems").checked;
     var rejectedItems = document.getElementById("rejectedItems").checked;
     alert("Inside apply() method.");
     alert("newItems= " + newItems + ", rejectedItems: " + rejectedItems);
     window.location = "<c:url value='/list/'/>" + newItems + "/" + rejectedItems;
     alert("window.location= " + window.location);
     alert("Add extra delay!");
     return false;
</script>This is my Controller class:
// Method1: this method gets called when the user loads the page for the first time.
@RequestMapping(value="/list", method = RequestMethod.GET)
public String list(Model model, HttpServletRequest request) {
          System.out.println("Controller: method1: Passing through...");
          model.addAttribute("newItems", Boolean.TRUE);
          model.addAttribute("rejectedItems", Boolean.TRUE);
          // Does other things.
// Method3: this method gets called when user checks/unchecks one of the checkboxes and clicks on Apply button.
@RequestMapping(value="/list/{newItems}/{rejectedItems}", method = RequestMethod.GET)
public String list(@PathVariable Boolean newItems, @PathVariable Boolean rejectedItems, Model model, HttpServletRequest request) {
          System.out.println("Controller: method3: Passing through...");
          model.addAttribute("newItems", newItems);
          model.addAttribute("rejectedItems", rejectedItems);
// Does other things.
     }The way my jsp code is written now, it calls the correct method and displays the correct url. When page loads for the first time, it calls method1 and the url is:
http://localhost:8080/dir/list
When the user checks/unchecks one or both checkboxes and clicks on apply button, method3 is called and this url is displayed:
If both checkboxes are checked which both booleans are set to true:
http://localhost:8080/dir/list/true/true
Everything is fine... however, if I comment these two lines at the end of JavaScript apply() function,
alert("window.location= " + window.location);
alert("Add extra delay!");Then method3 will never gets called; only method1 gets called and I see this url:
http://localhost:8080/url/list//?newItems=%23&rejectedItems=%23&apply=Apply
I do not know why it gets confused bet. method1 and method3 and cannot pick the right method?
I tried to use the POST method instead, but the page goes directly to our internal error page and it never reaches the method I wrote in my controller for POST:
I don't really know what I'm doing wrong? Any help is greatly appraciated.

I changed the <form> in the jsp to div and its working fine. I do not need to have comments in JavaScript funcion() anymore. I don't know why that made the difference though? According to:
http://www.w3schools.com/tags/tag_form.asp
The <form> tag is used to create an HTML form for user input.
The <form> element can contain one or more of the following form elements:
<input>
<textarea>
<button>
<select>
<option>
<optgroup>
<fieldset>
<label>
An HTML form is used to pass data to a server.
I do have <button> and also send the data - the value of checkboxes - to server. So I think it should also work with <form>.
Please let me know if you have any idea. Thanks.

Howto call the @Remove method of a stateful session bean after JSF page ...

I use EJB3, JPA, JSF in my web application. There are 2 database tables: Teacher and Student. A teacher can have many (or none) students and a student can have at most 1 teacher.
I have a JSF page to print the teacher info and all his students' info. I don't want to load the students' info eagerly because there's another JSF page I need to display the teacher info only. So I have a stateful session bean to retrieve the teacher info and all his students' info. The persistence context in that stateful session bean has the type of PersistenceContextType.EXTENDED. The reason I choose a stateful session bean and an extended persistence context is that I want to write something like this without facing the lazy initialization exception:
<h:dataTable value="#{backingBean.teacher.students}" var="student">
<h:outputText value="${student.name}"/>
</h:dataTable>Because my session bean is stateful, I have a method with the @Remove annotation. This method is empty because I don't want to persist anything to the database.
Now, my question is: How can I make the @Remove method of my stateful session bean be called automatically when my JSF page finishes being rendered?

How can I call the create method in BO from Application Service

Hello!
When I create a Business Object, CAF generates some methods automatically.
How can I call the create method in the BO from Application Service logic?
When i call the method then the entityManager and the sessionContext is NULL.
How can I initialize this?
Can anybody help me?
Thanks, Thomas

If you are using CE 7.11...
1) In the Application Services, add the BO as dependant object in dependencies tab.
2) In the implemention, add the following codes to call create method of the BO:
this.get<BO>.createMethod();

Calling the "getData"-method : does it connect to the source ?

Dear all,
Does a call of the "getData"-method make a connection to the underlying source, eg a BEx query ?
Or does it only read from the loaded Data Source in the application ?
Many thanks
Hans

Hi Hans Segers,
getData gives the results based on loaded query in application
For example:
this is actual query in QD
SNo Sname Marks
1     name1     10
2     name2     20
3     name3     30
4     name4     40
Implement getdata lets say
DS_1.getData("Marks", {"SNo": "1", "Sname": "name1"}).value;
getData returns the value : 10
Now you filter data source in Application/browser lets say
DS_1.setFilterExt("Sname", "name2;name3");
now resultant loaded query in application is
SNo Sname Marks
2     name2     20
3     name3     30
Now if you implement getdata
DS_1.getData("Marks", {"SNo": "1", "Sname": "name1"}).value;
getData returns : 0
Because there is no current data for name1 in application but in Underlying query has all the details
Hope you understood. :-)

Does it matter if I call the same UDF several times in my mapping?

Hi !
I have to map one TXT file to an IDOC. One field of the source file is needed to define values of several IDOC target fields.
I've developed an advanced java UDF that receives the source field, calls an RFC via JCO to convert the source value, and returns the converted value.
Then I use this UDF as part of the graphical mapping, to define the values of about 10 or 15 fields of the IDOC. That is, the UDF is placed 10 or 15 times, one time for each target field.
My doubt is if this an expected way of solving this kind of problem..I'm worried about calling the UDF (RFC via JCO) about 15 times for each source file record...and they could be 1000 aprox !
I've added a trace, and a global variable, and inside the UDF, I check if the current input value is equal the last processed value, if it is that case, then I return automatically the buffered value (in a global variable), avoiding the call to RFC....
Checking my trace...I see that the UDF is called with several different input values in some random order, so my "optimizacion method" does nothing.
Some ideas?
Thanks. Have a nice weekend.

Hi Matias,
we had a similar problem, and we solved it using a java has table stored in the global container.
During the mapping program, every time a new source-value has to be look up, that value becomes a new key of the hash and the result of the RFC call (target-value) is stored in the hash table as the value corresponding to that key.
So this avoid the problem of random calls with different values and you can read from the hash table if a value already exists in the hash table before calling the lookup RFC.
We implemented this solution and it works like a charm
Hope it helps,
Kind Regards,
Sergio

Calling the subclass method.

How to call the method of a sub class which is redefined in the subclass.
1. The super class also has the implementation.
2.No separate instance method is created for the sub class(which creates
instance) .
3.There is a method s_instance of the super class which is static.
4.Therefore the s_instance cannot be redefined.

Hi,
static methods are called using classname=>method_name. There are no instances for static methods. so CALL METHOD super_class=>s_instance...
I do not understand how a method can have the name s_instance ?!

Step into method- call the same method (bermuda triangle)

I don't know why but I have:
step into method1-> call the same method1->step into method1-> call the same method1->step into method1-> call the same method1 and so on.
Off course, the result is error "stack over flow".

How to call the show method of Popup from backing bean?

Hi!
I wanted to display the results of a search form in a dialog that is placed in popup.
That is The content of the popup will be rendered from the backing bean, dynamically .
And so when the form is filled and the submit button is clicked, the form fields have to be submitted to the server, and the results are to be displayed in the dialog,after the PPR response has arrived, and not at the time of calling the PPR.
Could you explain How this can be achieved?
Samba

Samba,
The fix for the popup in a template is to give the template an id say "template" and reference the popup in the JavaScript as "template:popupId", where popupId is the value of the af:popup's id attribute.
Regarding DWR, Joe really did a nice job with this framework. I have to say he got my attention. The one issue though is that JavaScript is an absolute must when using DWR and other frameworks that have a heavy JavaScript tilt. Dealing with JS can be a bit of a hassle due to x-browser idionsyncrascies as well as slow exection of JS. That said I believe Joe has one of the best JS solutions around.
On the flip side of this ADF Faces is trying to do something a bit different. Firstly, we want to avoid JS. The user should handle as little as JS as possible. In addition,
ADF Faces has the benefit of a server-side component framework we want to leverage this to make sure there is a limited amount of JS execution on the client.
So if you want to work with JS, DWR is a good solution. If you want to work with, Java, standards, and a great tooling environement ADF Faces is a better choice.
Finally, "Reverse AJAX" is a marketing term for "Push". You probably have also heard the term Comet. There are some varations on the protocols used but all-in- all. We are talking about one thing, the ability for the server to "Push" information to the client. Luckily, we provide this ability in a feature called active data channels. You will see this feature in the next preview. By setting an attribute value in a pageDef trees, tables, and BAM components can recieve data from the server via "Push".

af:fileDownloadActionListener not calling the bean method

Hello,
I am using Jdev 11.1.1.6.
I have a page where user can generate the report and download it. I am using <af:fileDownloadActionListener> for this on my jsff (implemented as region using BTF).
The commandbutton with <af:fileDownloadActionListener> is calling a backing bean method. When user clicks the "Print" button, it is supposed to generate the report and allow user to download it.
The issue here is that the control never goes to bean method after button press. The browser keeps showing busy but no control passed to bean method. Interestingly, after you close the browser, it immediately goes to bean method.
I have tried waiting for long time (some times 15-20 min) but it never goes there during execution.
What could be going wrong here?
Code snippet from my jsff:
<af:commandButton id="cb1"
                  textAndAccessKey="Print"
                  partialSubmit="false"
                  clientComponent="true">
               <af:fileDownloadActionListener method="#{someMethod}"
                                              filename="#{someName}"/>
</af:commandButton>This is really frustrating as I have no clue what is going wrong here. The similar code works in other page but not here.
I would highly appreciate help here.
Thanks,
Jai

Like I said, it is working fine on my other pages and I tried on new page, just like yours, and it worked. It is not working where I need it.
I know the issue is somewhere with my page [child or parent, explained later] and I am looking for help on finding the root cause. Some direction/tip which I can follow and figure out the issue.
Other buttons are working fine on the page but <af:fileDownloadActionListener> does not work. The page seems to go in loop as it keeps printing generic messages that are generally printed when page is submitted.
This will continue until you close the page/browser and then the control goes to bean method.
Let me explain page structure:
My application is based on UIShell and is basically based one page application. Every page (jsff) is implemented as region using BTF. When user clicks on menu, MainPage is opened. This MainPage represents main structure using layout components like panelGroupLayout, panelTabbed, showDetailItem etc. These layout components contains <af:region> implemented using BTF.
The MainPage which has this issue is large page with almost 100+ BTF af:regions implemented under panelTabbed+showDetailItem combination.
<af:fileDownloadActionListener> has been implemented on one of the <af:region>, which is part of this MainPage.
Few Observations:
1. If I move this button [with <af:fileDownloadActionListener>] to any of the af:region under current MainPage then it does not work.
2. If I move this button [with <af:fileDownloadActionListener>] to any independent page or any <af:region> which is part of some other MainPage, then it works.
3. Other MainPage where it is working fine is also a fairly large page with almost 150+ BTF af:regions
4. All our MainPages are based on template, so there is very high level of consistency in behavior and other handlings.
For whatever reason, it is not working on my current page and I would highly appreciate any input based on above info [or otherwise] to find a root cause for this issue.
If I need to debug, where should I start? What could be causing that looping behavior, specially with <af:fileDownloadActionListener>.
Thanks,
Jai

Not calling the action method??

hi ..
now i up with some common problem...
i said as common problem coz i dont know where the error is occuring.
here is the description.
In my jsp
i am having a panel tabbed pane with 2 panes.
first pane contains some 20 text boxes with save button, used to save the entered records to the database.
second pane contains the summary page which displays all the records from the respected table with select option button(radio). By selecting the single radio button we can edit the particular record by getting the same in the first tabbed pane fields...
(here, i am using a javascript to select any one radio button in the form coz radio buttons are generated thru datatable)
In java
======
in constructor
i populate all the data from the table to a list. and i display the populated data to the summay fields.
save button action
saving the data to the table
edit the value
updating the edited values
Here, my problem is after entering all the fields in the first tabbed pane
i click the save button. if there is no data in the table(database) all things working properly, but if there single data, save function is not calling. but the constructor are calling properly.
i am using hibernate for the database conn.
i know this is some sort of logical error, i am posting this only if any one who had already face this type of error(might be in setting session values).. suggestions plz..
