DWR + ADF Bindings get Binding Container at the Filter level

Hi I'm still pressing on to use DWR with the ADF Bindings.
To do this, The managed bean method called from javascript needs access to the BindingContainer object or the "#{bindings}" property which is not available out of the box when setting up DWR according to their documentation. So I need to maybe an additional filter or extend the DwrFilter to do this.
Any ideas how to get or create the bindingContainer object or the "bindings" during the execution of the FacesFilter stage?

Hi,
see Duncan Mills article about Ajax auto suggest: http://www.oracle.com/technology/products/jdev/tips/mills/AjaxAutoSuggest/AjaxAutoSuggest.html
pay an extra attention to the way he configured a pageDef file for the suggest servlet

How to get BOM compoents at the lowest level using BOM tables?

I am doing a report based on CK13N wherein i hav material and plant as the selection parameters and based on that i get the product costing of the entire BOM.
I pass material to MAST.get the BOM num and usage
Pass it to STAS and get STLKN (ITEM NODE NUMBER)
After that i pass STLKN and STLNR(BOM number) to STPO to get the BOM subitems based on UPSKZ(Sub items indicator). But that fails because UPSKZ is nt set for all the assemblies.
So hw do i get the BOM components at the lowest level USING these TABLES

Ashwin
1) As Taj Said, Sub item is not actually a item or component.
2) The sub item number what we are viewing the sub item sceen will be 001,002 like ,it not mean any item
3) For Example a car has 4 wheels, so the item/component description is WHEEL
4) The BOM Quantity of wheel is 4
5) In BOM General item over view, you can select the wheel then click subitem
6) This will lead to sub item screen
7) There you can see subitem 001,002,003 then installation point,subitem text,qty etc
8) Against installation point you can decalre Front Left,Front Right,Rear Left,Rear Left
9) Against sub item text,qty you can declare Front Left wheel-1,Front Right wheel-1, Rear Left wheel-1, Rear Right wheel-1 no
9) This does not mean there are addition Sub items for wheel (ie) additional BOM component)
10) Just declaring the positions for fitting in the car to ease the Assembly Person for fixing the wheel
11) So if you get the cost for WHEEL as assigned in BOM item then ok, don't worry about sub item cost

Lets get Apple to increase the audio levels again

Hi everyone! Well, I sold my 2.16 C2D on eBay and I just bought the new 2.2 model. I broke even selling the old and buying this one. So I think its a great deal. Anyway, I'm happy with the new machine. Speed and everything else is the same to me but the graphics are killer. Way better than the 128mb x1600. So far I've only tried it out on call of duty 2 but I'm more than satisfied.
So my reason for starting this thread is that we should all write to Apple's feedback section (which I can not find right now) and let them know that we would like the audio levels to increase again just like in 10.4.9.
The audio was low up to 10.4.8, in 10.4.9 the audio was much louder, and in 10.4.10 it went back to how it used to be. Now I know why Apple did this. It was because of all the 24" iMac users who complained about the audio being way too loud on the lowest volume setting. I know exactly how loud it was- my brother is one of those 24" iMac users. Reverting the audio level makes sense for iMac users but for everyone else its a downgrade. Especially since Apple sells a lot more notebooks than desktops.
A solution to this would be putting out a patch for just notebook users. Its really a major issue to me and I have not upgraded to 10.4.10 on this new machine because I'm in love with the fact of actually being able to hear the speakers on the MBP.

Are you serious? I'm running 10.4.9 right now I can't hear anything on iTunes until the 2nd or 3rd volume setting. Yes, I have sound check and everything else off.
Don't even wanna imagine what it will be like again when I have to go to 10.4.10.

Requirement to get Inventory data at the Daily level (non-cumulative KF)

Hello All,
Kindly provide ur suggesstions on the issue mentioned below:
We require the Inventory data at a daily level. Also we require that the non-cumulatve Key Figures such as 0TOTALSTOCK, etc. be available to us in the BW itself, since this is required for further processing.
PS: Right now we are using RSCRM_BAPI to execute the qurey and store the data into a table, but it fails for non-cumulative keyfigures. Kindly suggest if ther are other ways which can suffice the requirement mentioned above.
Thank you.

Error because of wrong page definition/binding container

Hello -
(Using JDev 10.1.3 JSF w/ADF BC)
I'm running into a weird "issue" involving setting up the binding container.
I have one page that has a table of data. I select a row and hit a button to navigate to a page with an edit form.
In the page definition (for the page with the edit form), I list a managed bean as the ControllerClass. (I use the bean as a PagePhaseListener.) I've also added bindings (#{bindings}) as a managed property for that bean.
In the managed bean I grab a hold of an attribute binding from the binding container in my beforePhase method (when the phase id is Lifecycle.PREPARE_RENDER_ID). However, I was always getting NULL for the attribute binding (which then caused a null pointer exception).
When I paused the execution in the debugger, it looks like the binding container was still set up for the previous page (the page with the table in it). Opening up the bindings variable, I found a member mBindingContainerDef which had members mObjName and mFullName which seemed to indicate that the binding container was the one for the previous page, NOT the page with my edit form. (mFullName had the full name and classpath for the first page's page definition.)
Why is this? I only indicate that the bean is a ControllerClass in the page definition for the 2nd page --> so shouldn't that be the binding container in effect when the PagePhaseListener methods are executed?
-- Scott

Scott,
I assume that your PhaseListener doesn'tdistinguish between the actual navigation and the JSF postback that is issued to the same page. In your case I assume that the PhaseListener is invoked on postback and thus ADF Faces points to the "old pagedef" file.

ADF Bindings Servlet/Filter not invoking Faces Servlet

I'm getting ADF Faces and Facelets working properly with pages written in jspx format, but the Faces Servlet being mapped to jsf format.
The problem I'm getting is while displaying ADF Tables with data retrieved from the database using Toplink and bindings provided by ADF Databindings.
The following is the Web.xml mappings for Faces Servlet and ADF bindings filter:
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>resources</servlet-name>
<url-pattern>/adf/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.jsf</url-pattern>
</servlet-mapping>
<filter>
<filter-name>adfBindings</filter-name>
<filter-class>oracle.adf.model.servlet.ADFBindingFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>adfBindings</filter-name>
<url-pattern>*.jsp</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>adfBindings</filter-name>
<url-pattern>*.jspx</url-pattern>
</filter-mapping>
I'm getting the ADF tables displayed using ADF Bindings, if the faces servlet is mapped for jspx format;but, at the cost of losing Facelets...Facelets is not working with Faces Servlet mapped to jspx format(though written in jspx format, the faces servlet mappping has to be made for jsf format.On the other hand, if I use faces servlet mapping for jsf pages I'm getting Facelets working but ADF Databindings are not working ,(I guess) and hence ADF Faces Tables are not being displayed(I'm getting Access Denied message).
I even tried to change the ADF binding filter mappings
---- from ---- jsp &jspx---- to ----- jsp and jsf ----
But I got the same Access denied message.
I read a similar post on this forum by Mr.Ashish Kumar who said he is using java script and automatic form submission, to refresh the page and that gave him the table working.
as quoted in the post:
af:table displays Access Denied
Why should the page be refreshed at all. I Guess , the Faces Servlet is not being invoked by the ADF Bindings Filter/Servlet, and for this , I suppose , Mr.Ashish is using java script to provide the action required.
And one more thing which that Automatic Refreshing of page using JavaScript cannot do.
Suppose,
I need customised display, rather than just a Table or Form,like:
public String getEmp() {
BindingContainer bindings = getBindings();
OperationBinding operationBinding =
bindings.getOperationBinding("findAllEmp");
Object result = operationBinding.execute();
if (!operationBinding.getErrors().isEmpty()) {
return null;
List<Emp> res=(List<Emp>)result;
for(int i=0;i<res.size();i++)
Emp myrec=res.get(i);
System.out.println("Employee ["+myrec.getEname()+"], Salary ["+myrec.getSal()+"]");
return "";
where I do some customisation in the backing bean.
and I call that method binded to a button as below:
<af:commandButton
text="findAllEmp"
disabled="#{!bindings.findAllEmp.enabled}"
binding="#{backing_Success.commandButton1}"
id="commandButton1"
action="#{backing_Success.getEmp}"/>
What I'm getting is a disabled button.
Why doesn't ADF bindings servlet invoke the faces Servlet?
Can't we make ADF Bindings Servlet invoke Faces Servlet by configuring in the web.xml?
Can't we get ADF Bindings filter mapped to work with jsf pages?
Won't ADF Bindings work with jsf pages, will they work only with jspx pages?
ADF Team,
Please Help me.
Thanking you,
Samba

Hi! Frank,
Thankyou for your Reply.
Yes, Mr.Adam Winer has contributed that library, I guess.
But I already have that adf-facelets.jar in my lib folder ; and with out that the Facelets won't work with ADF faces , in the first place.
I'm getting Facelets working excellently with ADF Faces but I'm not getting ADF Bindings working with Faceletpages.
The thing is even in another application which does not have facelets in it, if we use mapping for jsf pages, ADF Bindings are not working.
I think the ADF bindings filter is configured some where to work with jspx pages only.Could you tell me where to change that entry to make ADF Bindings work with jsf extension?
Thanking you,
Samba.

Do I need to cleanup runtime binding container and iterators?

If I create a runtime binding container and iterator in a JSF session bean as follows:
FacesContext facesContext = FacesContext.getCurrentInstance();
ValueBinding valueBinding = facesContext.getApplication().createValueBinding("#{data}");
BindingContext bindingContext = (BindingContext)valueBinding.getValue(facesContext);
// To create JUIteratorBinding, we need the following objects
DCDataControl dataControl = bindingContext.findDataControl("MyDataControlName");
ApplicationModule appModule = (ApplicationModule)dataControl.getDataProvider();
DCBindingContainer bindingContainer = new DCBindingContainer();
// Create dynamic iterator. Need to set bindingContainer otherwise executeQuery throws exception
JUIteratorBinding iterator = new JUIteratorBinding(bindingContext, dataControlName, "MyViewObjectName", "MyIteratorName", -1);
iterator.setBindingContainer(bindingContainer);....do I have to later clean down the iterator and binding container from the data control to release the memory (and what calls do I need to make), or once the objects fall out of scope in my code are they marked for GC?
CM.
PS. JDev 10.1.3.1, ADF BC and JSF

Hi Steve, thanks for the follow up.
I'm coding a dynamic menu <af:page> control that maps to the MenuTreeModelAdapter (session bean) as detailed in the JDev 4GL/Forms guide.
I've made a change that instead of loading the menu items from the hardcoded faces-config.xml file, they're actually sourced from the database via the code above, which is placed in the MenuTreeModelAdapter constructor. As the <af:page> tag exists on a number of pages, and thus the MenuTreeModelAdapter may be instantiated for the first time from a number of different locations, I can't hard-code the binding container or iterator into any single pageDef file. Thus I dynamically construct it in the constructor when the session bean is created for each user. I require a session bean as the menu items are different for each user.
However I'm concerned once I've created the binding container and iterator, that even though the session bean may become invalidated, the 2 binding layer constructs may remain, consuming resources.
Thanks for your assistance.
CM.

SelectOneChoice 'real' value -bindings.get- error

I've implemented the following code in my backing in an attempt to pull the 'actual' value from the selectOneChoice list box.
int rangeIndex = (Integer)valueChangeEvent.getNewValue();
// new value only gives you the index
DCIteratorBinding regionsIter =
(DCIteratorBinding)bindings.get("RegionsLOVIterator");
Row row = regionsIter.getRowAtRangeIndex(rangeIndex);
// get the selected region
String region = (String)row.getAttribute("RegionName");
I'm receiving a compile error on ' bindings.get ' Can someone give the rest of the code where binding's gets set? Thanks

I was able to get the desired result by adding the following code:
In the faces-config.xml add the following:
<managed-property>
<property-name>bindings</property-name>
<value>#{bindings}</value>
</managed-property>
Then go to the backing bean of your page and add this at the top:
private BindingContainer bindings;
next, right click select refactor --> encapsulate fields to create the getter and setter for the BindingContainer
Lastly, add the following code to get the 'real' value based on the index of the selection.
DCBindingContainer bindings = (DCBindingContainer)getBindings();
DCIteratorBinding regionsIter =
(DCIteratorBinding)bindings.get("AuthorizedCagesView2Iterator");
Row row = regionsIter.getRowAtRangeIndex("insert index value");
// get the selected region
String ei = (String)row.getAttribute("column attribute");

To check who change the trace level

Hi All,
Can anyone please help me how can i get that who change the trace level in system, in our client lot of people have Sm50, St01, St05,ST12 and other trace transactions, and it become difficult to track down who is changing the traces level
people often change the trace level and forget, and it become difficult to track down the changes,
can someone help me how can i know that trace level are changed by which user id at what time
Thanks,
Dinesh

I cannot remember the exact names, but if you take look in those transactions (there are more than the ones you have listed..) then you will see a call to FM TH_CHANGE PARAMETER.
You will see the name of the dynamic profile (and the authority check in it against S_ADMI_FCD action ST0M etc...) there, or some checks performed before the function is called.
Then take a look in transaction TU02 for the history of the parameters...
Good luck,
Julius
ps: A popular error exists in transaction SMGW: Wanting to dynamically set the gateway logging via the Expert Functions menu, you might be tempted to increase the "Trace level"... This is the ST11 developer trace!!! Rather choose the Security sub menu and activate the gateway specific log there, otherwise your production system might have some performance problems from the developer trace (which is a different local topic of less interest for gateway security....).

How to get two syslog resources with different filter levels into ASA

Hi All,
I have my ASA's set up to push logs to my syslog server:
logging host inside 198.xxx.xxx.185
logging trap notification
However, I would like to also trap if a VPN on my ASA's go down, but I want to send that to my SNMP server, NOT my syslog server. I also want to only trap that VPN log message and nothing else, so I want to set the filter level to emergencies:
logging host inside 198.xxx.xxx.16
logging trap emergencies (+ system message 123456)
How can I configure my ASA so that these two syslog destinations will have separate respective filter levels of notifications for .185 and emergencies for .16?
Also, does anyone know the System Log Message ID for a VPN tunnel going down?

Dear Ronny,
i am gining the solution below.But would request you to change your ITAB STRUCTURE LIKE THIS BEFORE USING THE CODE
VERME LGPLA
252.000 EA 300 0149A 0149 410
276.000 EA 300 0149A 0107 410
516.000 EA 300 0149A 3013 400
528.000 EA 300 0149A 3013 400
528.000 EA 300 0149A 3013 400
528.000 EA 300 0149A 3013 400
528.000 EA 300 0149A 3013 400
528.000 EA 300 0149A 3013 400
528.000 EA 300 0149A 3013 400
then do as follows.
SORT ITAB BY LGPLA VERME.
LOOP AT ITAB INTO WITAB.
W_INDEX = SY-TABIX.
here take all the abOve fields in temp fieds.
LW_VERME = WITAB-VERME..AND SO ON.
AT END OF LGPLA.
   MOVE: all LW fields to work area of ITAB1
   APPEND work area of ITAB1 TO ITAB1.
   DELETE ITAB INDEX W_INDEX
ENDAT.
ENDLOOP.
Basically what u r doing here is thet u r using processing event.
So whenerv VERME changes this event will be triggered.
Just try this out...something like this only will be he logic.
Please let me know further

BackingBean Method call from Task flow isnot getting the Binding Container

About the adf Bindings object

As far as I know, the page definition xml defines the datasource(such as the return method in the data control panel) of the .jspx page. when i intend to show the label text dynamically, i should use the Expression builder. then it popups a dialog where i can build the el visually. the problem is
1.when the label is in a table,then i can build the el in two ways:#{row.name} or #{row.bindings.name.inputValue}. what's the difference?
2.if the label is in a tree, i will have to use another variable node,so it's:#{node.name}. i want to know where the variable "row" and "node" is defined?
Besides, there are aslo objects: adf bindings,adf managed beans,jsp objects. how and when should i use me? some detail learning materials are expected. because it' hard to explain in words.
Edited by: Tom on 2011-8-4 下午7:14

Here is the explanation assuming model as ADFBC,
row.name
row here is a ViewRowImpl class, if you have any custom rowimpl class generated for the view object, it would be referring that else refers to ViewRowImpl. row.name uses introspection and calls getName() method inside ViewRowImpl or custom row impl class.
Here, the first letter of name should be lower case always so that the introspection would be applied
row.binding.name.inputValue
Gets the current row attribute value from the binding instead from the row directly. Here the case of the name should match the attribute name in view object. If the attribute name is "Name", EL should be "row.binding.Name.inputValue" or if it is "name", EL should be "row.binding.name.inputValue"

How to get an external binding container

Hi friends.
I'm migrating now to jdeveloper 11g
Can anybody tell me how to get a reference to an external binding container. i found the decision:
     FacesContext fctx = FacesContext.getCurrentInstance();
                 ELContext elc = fctx.getELContext();
                 ValueExpression vle = fctx.getApplication().getExpressionFactory().createValueExpression(elc,"#{bindings}",DCBindingContainer.class);
                 DCBindingContainer bc = (DCBindingContainer)vle.getValue(elc);
                 if (bc == null) {
                     return;
                 BindingContext ctx = bc.getBindingContext();
                 DCBindingContainer dcb = ctx.findBindingContainer("jurDialogPageDef"); but it never works!!!!
bc is always null.
neither simplier the approach works
        BindingContext _ctx=BindingContext.getCurrent();
        DCBindingContainer dcb = (DCBindingContainer)_ctx.findBindingContainer("jurDialogPageDef");
        DCIteratorBinding jurIter = (DCIteratorBinding) dcb.get ("JurPersonView1Iterator"); dcb is null though the jurDialogPageDef.xml does exist.
Thanks in advance. Alex.

Get bindings of a region in the page

Hi folks,
I am using Jdev 11.1.1.4.0
I have a page fragment which has a region inside it and other components too. The components (not part of the region) are bound to a view object. I get the bindings of this page using
FacesContext fc = FacesContext.getCurrentInstance();
fc.getApplication().evaluateExpressionGet(fc, "#{bindings}", oracle.binding.BindingContainer.class);
Now I iterate over the executable bindings to get the JUIteratorBinding inside the region (taskflow). But the VO iterator for this gives me null values for its attributes even though the screen has values displayed inside the components.
The VO for the components not part of the region above displays the correct values. Its just the problem with the iterator in the taskflow. What might be the issue here?
Thanks
Vishal

Here is a simple explanation of my use case. I have a page with a region, and below it, there is a form to display/accept some fields. When I click on save button on the page, I need to capture the values inside the region as well as the form below it. So I need to access the view object inside the region.
Thanks
Vishal
