Can Any One Reply as It is urgent Req...
Thanks ,,

Instead of using the VO attribute names to set and get values, best to go to the VO definition, click on Java, and generate the View Row Class with the accessors.
In the class where you're trying to set attributes, instead of a Row class, use the View Row class of your VO (eg ViewObjectName's class would be ViewObjectNameRowImpl), and when retrieving a row from the VO, cast the row to the previously mentioned View Row Class.
At that point you can use the View Row Class's methods that would perform sets and gets of each column.
To get attribute names, I don't know off the top of my head, but there might be a method mentioned in the Javadoc for the ViewRowImpl or ViewObject or ViewObjectDefinition classes to get the attribute/column mapping, or perhaps you can somehow read the XML definition of the VO which has that mapping.
Assuming business components were built automatically and no attribute names were overridden, intuitively the attribute name is a camelcase version of the column name, removing understores and capitalizing the character following the removed underscore - but that's not a fool proof approach. Just a general observation.
Hope this helps.

How to access attribute

Hi all,
   I am new to webdynpro for ABAP. How to access the attribute which is directly under the root context.
ex.
Root Context
|
   Name   ---> attribute.
Regards,
Gnid.

Hi Gopi,
Accessing a context element or a context attribute requires to first have a reference to the related context node. The context root node can be accessed by the standard attribute WD_CONTEXT.
To Access a Node Element: After having accessed a context node, the reference to the element at lead selection of this node can be obtained by calling the method get_element( ). Thismethod returns a reference to the element instance of type IF_WD_CONTEXT_ELEMENT. Accessing the Node Element at Lead Selection The element with index n can be accessed using the method get_element( index = n ) .
Once we access the element we can access the attribute by GET_ATTRIBUTE().
Child nodes of the context root node can be identified using the get_child_node( ) method. This method returns a reference to the node instance of type IF_WD_CONTEXT_NODE. The get_child_node( ) method requires the name of the node and, optionally, the index of the element in the parent node to which the desired node instance belongs. In this case, the parent node is the context root, which only ever has one element; therefore, the index parameter is 1 (default = lead selection of parent element).
Best regards,
Suresh

How to retrieve attribute-names (not values)

Hi
I know that I can get all attributes by an XPath expression according to /AA/@* . But since I have a XML document in XMLType and when I use the "..extract( aXpath)" function, I get all the attributes of the corresponding node but as a concatenation of the values. How can I get the attributes names:
E.G.
AA
BB 12.3 /BB
CC 45.5 /CC
/AA
/AA/@* would return 12.345.5, but I need to know "BB" and "CC", any ideas ?

${applicationScope.abc}

You can define global variables by using a public variable on script-level. Just make sure you define it outside of any class definition. For example if you want to define a global environment, you can create a script Environment.fx and put there your global variables:
public var GLOBAL_VAR1 = 42;You can access this variable from anywhere with:
Environment.GLOBAL_VAR1 = ...

How to show Attribute name in Single line in ADF-JSPX pages

Hi,
I am having a issue , attribute name like "Name Of Catalog" in Brazilian-Portuguese Lang. is displaying in two lines instead of showing in one line, but it is correctly showing in English language.
And also this issue reproducible on IE 7 browser only. Please let me know your comments on above issue.
Thanks

Hi John,
I have seen some solutions like using horizontal layout, where child components are arranged in a horizontal line. No wrapping is provided when contents exceed the amount of browser space available. Is this OK to use?
One more question is, how to enable Portuguese - Brazil Lang for pages in Jdev ? in other words, I want to see Label Text in Portuguese - Brazil Lang instead of English ?
Thanks.

How to Access Attributes of Fields in VARIANT

Hi,
Can anyone let me know how we can access Field attributes of a variant? I need to change and create these attributes dynamically.
Below are the attributes of screen field saved when creating an variant
     Required field                            O
     Switch GPA off                            L
     Save field without values          P
     Selection variable                       L
     Hide field 'BIS'                            N
     Hide field                                    I
     Protect field                               P
    Field name                   Type   P I N L P L O
    P_REPID                        P                               X
    SO_VNAME                  S
For Example
If 'O' is marked as u2018Xu2019 against any field in the variant then it says that this field is OBLIGATORY
I want to access this sort of information of a variant.
Thanks
Rajgopal Dara

Hi RAJ,
Although the question is not so clear, but as far as i understand you want to see the attributes associated with all the fields in your variant. if so then you can go to maintain variant. just go to se38, select variant as radio button and change it. In the variant maintenance screen you can select change attribute of your variant. you can click on that and pass dynamically values (either from some table like TVARV or from program)
Hope this information will be helpful for you.
Cheers !!

Q: How to access and modify xml tags using Java

I have an xml based document that i need to access and change. For example, the code
<section id="section1">
<div>
<xforms:group id="id1">
<xforms:label id="label1">
<l style="font-size:16pt"> something </l>
</xforms:label>
</xforms:group>
</div>
</section>
Working with Java I need to access all the tags, select some of them that are relevant to the current device and remade the document. I thought I would read the file character by character identifying the different labels and building a tree, storing in the tree nodes the relevant information as some kind of attributes (for example, in the case of the <xforms:group id="id1"> I would name the node "xforms:group" and create an "id" attribute with value "id1"). I'm not sure if that is the most efficient way of accessing the problem (computational power might be an issue), and would appreciate some help on the subject.
Thanks,

this may help you..
this is a little util i made to help me read/write files.
using this, you are only one step away from your solutions, you only need to figure out the regex you need to run on the text of the file to make it become what you need it to become.
though if you use non-standard encoding, you might not want to use this code..

How to Access Item Names Property of ListBox inside of Cluster?

In LabVIEW 2010 I have a Cluster of Controls on the Front Panel. In that Cluster I have a ListBox. How do I access the Item Names Property of the ListBox in my Block Diagram.
From the Cluster, I can get the ListBox, but that returns an I32 value, probably the index of the selected Item.
In the Block Diagram, how can I get the Item Name Property of the ListBox from a Reference to the Cluster?
THANKS.
Solved!
Go to Solution.

by using the "controls" array of your cluster, you can access the individual elements. You have then to convert the reference to a "more specific class" using a reference to an arbitrary listbox (or a constant reference of the required type), then you can access all properties of your listbox.
THINK G!! ;-)

How to access attributes of an instance?

For example, I declared an instance of a CustomNode class "workspaceRow".
     Group{
         translateX: 50
         translateY: bind (wsY * -1) + (i*25);
         content:[
                 workspaceRow{
                      lineNumber: i.toString();
                    myColor: theColor;
                    onMouseEntered: function( e: MouseEvent ): Void {
                        selectedRow = i.toString();
     }How do I access lineNumber? I'm trying to use it for the onMouseEntered function inside the workspaceRow (as seen above), but Eclipse says it cannot find lineNumber, because it's looking for it at the top of the hierarchy (as in, looking for lineNumber declaration on my main *.fx file, instead of inside the instance). It's because I need to be able to store some data inside, and retrieve it later on.

For that lineNumber thing, sorry about that. I was trying to access it in the onMouseEntered function, but decided to use var "i" instead, since it was what I used to generate a loop, and I use that same variable for lineNumber, but I know it'll give me problems later on.
Yeah, forgot about capitalized class names, and yes, WorkspaceRow is a class extending CustomNode.
Thanks a lot, your way worked. I am just wondering though, why doesn't JavaFX want to put the declaration and instantiation of the node inside Group{}? When I move those code blocks inside, Eclipse highlights the line "Group{" and says "unexpected type required: variable found : value".
If I proceed with initializing the instance right on the declaration inside Group{}, it says "This is the type of cyclic reference to workspaceRowNow that prevents type inference.". As in like this:
          var workspaceRowNode = WorkspaceRow{
                 lineNumber: i.toString();
               myColor: theColor;
               onMouseEntered: function( e: MouseEvent ): Void {
                   selectedRow = i.toString();
                   print(workspaceRowNode.lineNumber);
          }Can anyone explain what that means?
