Value nodes with depth in Context - programmatically binding.

I am resonably new to Java Webdynpro and have been unable to solve this issue so far if someone has a link to a implementation (pseudo code) it would be greatly appreciated.
I have a context supplied from an interface that is not flat.
With data in the context it may look something like this with value attributes in each Node
Context -
-Node A1
           --- Node B1
           --- Node B2
- Node A2
           --- Node B3
           --- Node B4
If the A nodes where only nodes I could loop through the number of Nodes I wanted to create, something like;
   INodeAElement tempNode = wdContext.createNodeAElement();
   tempNode.setAttributes ..........
   wdContext.NodeNodeA.bind(tempNode).
or build and arraylist and bind that ...but when it comes to a Node with daughter Nodes I havent the slight idea of how to build the structure. I'm sure its a very simple answer but I have no idea how to do it, and I havent been able to find any reference on how to do it.
Can anyone point me in the right direction ..
thanks in advance.

Context -
-Node A1
--- Node B1
--- Node B2
- Node A2
--- Node B3
--- Node B4
It depends on if the B-nodes are singleton or non-singleton child nodes.
For non-singleton child nodes there exists one B-node for each A-node-element.
In that case the context can be filled like this:
IA1Element a1 = wdContext.nodeA1().createAndAddA1Element();
for (int i = 0; i < some_number; ++i)
IB1Element b1 = a1.nodeB1().createAndAddB1Element();
for (int i = 0; i < some_number; ++i)
IB2Element b2 = a1.nodeB2().createAndAddB2Element();
And so on.

How to populate value node with values?

Hi Experts,
I have created a new view with a vlaue node of table type.
How can I populate values into the value node?
Which method will be useful?
Is there any material for Web UI Programing?
Please help me in this.
Thanks,
Adi.

Hi Adi
If ZVal is your value node then,
DATA: lref_entity    TYPE REF TO cl_bsp_wd_value_node,
        lref_bo_coll   TYPE REF TO if_bol_bo_col,
        lref_data TYPE REF TO <<your ZStructure>>,
         ls_data type <<your ZStructure>>.
ls_data-<<field1>> = 'XYZ'
ls_data-<<field2>> = 'XYZ'
     CREATE OBJECT lref_bo_coll TYPE cl_crm_bol_bo_col.
      CREATE DATA lref_data.
      CREATE OBJECT lref_entity
        EXPORTING
          iv_data_ref = lref_data.
      lref_entity->set_properties( ls_data ).
      lref_bo_coll->add( lref_entity ).
      typed_context->ZVal->set_collection( lref_bo_coll ).
Hope this was helpful.

Unable to add value to model node with cardinality 0..n

Hi All,
Im working with Webdynpro Java.i have an issue here.i have a input field item named customer and a drop down box item location.when i give customer and location as inputs,a WSDL (named Equipment WSDL) is called.the result is a drop down list containing equipments id
i took a custom node location with cardinaliy 0..n.i gave static values as input for location.i need to set the location values to model node location.when i m giving a single value to custom node location,that static value is not accepted by model node location(in WSDL) whose cardinality is 0..n.
Please suugest a solution for this issue
With Regards,
Ushasri.

HI Ushashri,
What do you mean by 'static value is not accepted by model node location'
how you have done the mapping
send me the hierarchy of rfc and ur value node

Also the EH_ONEXPAND has to be implemented and event handled in DO_HANDLE_EVENT. But this expand event has to be delegated to context node directly as CL_BSP_WD_CONTEXT_NODE_TREE will already have the implementation.

How to set values to the structure containing a node with cardinality 0..n

Hello.
I 'm trying to set values for the node with cardinality 0..n. The node type is "Fields".
<xsd:complexType name="Field">
   <xsd:sequence>
      <xsd:element name="fieldCode" type="xsd:string"></xsd:element>
      <xsd:element name="displayValue" type="xsd:string" minOccurs="0"></xsd:element>
   </xsd:sequence>
</xsd:complexType>
<xsd:complexType name="Fields">
   <xsd:sequence>
      <xsd:element name="field" type="tns:Field" minOccurs="0" maxOccurs="unbounded"></xsd:element>
   </xsd:sequence>
</xsd:complexType>
I need to set several values for the element "fieldCode" but it has cardinality 0..1 and BPM does not allow it but I did not find any option about how to set values for the structure of type "Fields". Could you help me?
Best regards,
Timur Semenchuk

Hi Marcus,
If there is no way you could change the cardinality of the node, and thus it can contain 0..n items, I think you should create-and-add a new element programmatically.
Since the collection can contain zero elements, I would add a 'new' button, which upon clicking adds one new element via:
IYourNodeElement yourNodeElem = wdContext.nodeYourNode().createYourNodeElement();
wdContext.nodeYourNode().addElement(yourNodeElem);
Hope this explains a bit!

Problem with invalidating a context node

Hi,
Please see the code below:
String s = wdContext.currentSubitemsElement().getBase_Quantity();
wdComponentAPI.getMessageManager().reportWarning(s);
wdContext.nodeSubitems().invalidate();
String s1 = wdContext.currentSubitemsElement().getBase_Quantity();
wdComponentAPI.getMessageManager().reportWarning(s1);
For some reason, the context is not cleared after the invalidate command. Any ideas for this?
Thanks in advance,
Aviad

Hi Aviad,
Let me guess the origins of problem:
1. As far as you mentioned <b>Sub</b>items node, there should be a parent node, say Items.
2. Subitems node has either supplying relation role or supply function, Items has no supply function.
3. Then, if you invalidate Subitems, supply function is called or supplying relation is used to populate content. When you do contenxt reset, then all controller nodes get invalidated including Items. Hence Subitems has no parent and displayed as empty.
If all the above is true, then you may either to invalidate Items node or make Subitems node with no supplier (i.e. manually bind content instead).
Context reset works here, but, it's a bit "brute force" approach.

Value not available in the context node

Hi,
I have created one custom component through BSP_WD_CMPWB with only one view called u2018partneru2019 with sample button.
In this view partner ,then created one model context node with reference to u2018 BuilHeaderSearchu2019 search component with only one attribute u201CPartner IDu201D.
When I test the component , WebUI screen shows partner id input box, and sample button. After entering partner id value in the input box, then I am pressing sample button. But entered value not available in the context node. Please help me, how can i get this value?

Hi,
Check the set_method of that attribute and compare with standard.

Problem replacing Null nodes with real values in XML documents...

Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit Production
Our friends in Java land are insisting on passing data between Java and PL/SQL using fairly small XML documents (don't ask). I then need to extract the input parameter values and pass them, on to the stored procedures that actually do the work. These return a result which needs to be returned to the java layer in the output XML document.
Here is a cut down version of the input XML...
<ParameterList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Parameter>
<Id>1</Id>
<Result xsi:nil="true"/>
</Parameter>
<Parameter>
<Id>2</Id>
<Result xsi:nil="true"/>
</Parameter>
</ParameterList>
and this is an example of what I am expected to return...
<ParameterList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Parameter>
<Id>1</Id>
*<Result>SUCCESS</Result>*
</Parameter>
<Parameter>
<Id>2</Id>
*<Result>WARNING</Result>*
</Parameter>
</ParameterList>
i.e. I am expected to replace the value of the Result node with a string indicating the succes or otherwise of the underlying PL/SQL process.
I am extracting the input values using the DBMS_XMLDOM functions and naively assumed that DBMS_XMLDOM.SETNODEVALUE could be used to update the value in the Result node - It didn't work so I resorted to reading the documentation which revealed that it will not work for a null node.
Am I going to have to use XSLT to generate the output XML from the Input and incorprate the result? Or is there a simpler way?
I have used XSLT in Oracle before and still have the nervous tick...

Thanks A Non,

How to search for a text node with a particular value in an xml document with labview

supposing i have the following xml document:

<bookname>the spear warrior</bookname>
<author>britney</author>

<bookname>the beard</bookname>
<author>derrick</author>
</book>
</head>
i want to search for the author of the book "the beard" using for example the V.I Get first match of labview to access the the node with value "the beard" and then use Get next sibling V.I and Get node text content to get get the author of this book..so my question is how do i write the xpath expression for Get first match so as to access the node with bookname "the beard" instantyly? am trying to minimise the use of loops because they increase the time duration,..thank you (NB:i dont want to use Get all Matched V.I because it obliges me to use a loop in order to access the name derrick and this increases the time duration for my v.i)

Since it's all text, why not use a real quick Match Pattern (or Regular Expression, but you don't need that much power here), see attached.

Replacing a value of a node with CDATA (as is)

Hi All,
How do I replace the value of a node such that it's CDATA format is preserved and not re-encoded. Currently, when I do similar to the following:
replace value of node doc(doc_name)/parent/node with "<![CDATA[[the data]]]>"
the less than and greater than signs are replaced with &lt ; and &gt ; respectively, losing its CDATA section status.
How do I replace the value such that within the resulting XML it is exactly "<![CDATA[[the data]]]>" and not "&lt ;[CDATA[]the data]]&gt ;" ?
Thanks in advance

John,
I am aware that it's synatic sugar. However, I actually need it to look that way. Thing is after edits, the resulting XML will be read by a component (that I have no access to change) which requires that node to have CDATA (as is) as it's value.
Anymore ideas; Anyone?
Instead of replacing the value (ie. replace value of node doc()...), I replaced the node (ie. replace node doc()...) with something similar to: <node>CDATA-section</node>. However, as expected only the data within the CDATA section gets persisted.
In this case could I turn something off or on such that xmldb leaves the CDATA-section as is? e.g. http://www.xquery.com/tips_and_tricks/including_CDATA_in_results.html
Thanks,
Cecil

Using XSLT to extract value of a XML node with namespace

I want to use XSLT to extract value of a XML node with namespace <job:location>, and the returned value should be string 'Sydney - Inner Suburbs & CBD'. I tried a few XSL code below, but failed with error or nothing was returned.
<xsl:value-of select="job:location" disable-output-escaping="yes"/>
<xsl:value-of select="job/location" disable-output-escaping="yes"/>
<xsl:value-of select="job\location" disable-output-escaping="yes"/>
<xsl:value-of select="location" disable-output-escaping="yes"/>
This might be an easy question for you, but I would appreciate if anyone can help.

Hi Suncorp IT Learner,
We need to tell the XSLT that some elements are in another namespace. Copy the xmls declarations for the prefixes you need to use. Then use the xsl format as:
<xsl: value-of select=”job:location/@PUReferenceID”/>
In following issue, Chriztian has a good explanation:

Hardcode values of the node with cardinality 0..n

Good day!
I need to hardcode a list of element to the node with cardinality 0..n.
Node has two attributes.
How can I fill the node with a few element in the input mapping? I know I can do it with a single element by separating values by comma. Is it possible to fill the node?

Hello.
I've the same problem. Can you say how to set list of values for a structure?
For example, we've node FIELD containing two attributes: ID and NAME.
FIELD is a node with cardinality 0..*. How to set at least two elements to the node?
Your example works only for simple attributes with cardinality 0..*, but it doesn't work for structures.

Binding value nodes to component in a view

Hi,
What is the use of these value nodes and value attributes? How can I bind them to, say a inputfield in my view? Can any change to the value node dynamically affect the inutfield?

Thanks to Peter Conrad for the answer. The answer's in a different post. I have included his reply below.
From a binding perspective there's no difference between value or model nodes/ attributes. you can always bind using the syntax
//<contextnode/attribute to the value attribute of the tag.
And yes, for accessing the value the SET_<attribute> and GET_<attribute> methods should be used in this case.
