Reading the Context Node in the same Component

Dear Gurus,
I have made enhancement to standard view and functionality is working fine.
Now i need to read the different context node (Different view) from the same component.
I try to do the way Webdynrpo read the context node but here there is Wizard and i stucked :-(.
Can you plz suggest or post small code to read context node.
Regards.

Hi,
If those two views are assinged to one viewset in runtime repositoty, you can read the secod view by following code:
lv_viewname = me->get_viewarea_content( 'Upper' ).      " here(me =view1)
IF lv_viewname IS NOT INITIAL.
    lr_viewctrl = me->get_subcontroller_by_viewname( lv_viewname ).
    IF lr_viewctrl IS BOUND.
from here you can read the context nodes.

How to read the context node of used component?

Hi,
I have component called : SRQM_INCIDENT_H. This component has used component - BTSTATUS.
Now, I need to read the context node of the BTSTATUS/UserStatus in GET Methods of Context node in SRQM_INCIDENT_H.
Can you plese help me out.
Thanks,
Sandeep

The component usages can be accessed from the component controller
You should however assure that the context node is present in comp controlelr of the used component.View context nodes cannot be accessed.
if not ,then you need to goto the component BTSTATUS ,add the context node explicitly to comp controller,and do correct bindings to the view context node.
Once you add the context node to the com controller,yo also need to expose it.
go to runtime repository->component_interface->interface_controller->context->right click and select ADD CONTEXT NODE, and add you newly creatde context ndoe of comp contorller here.
Now you cann access it using the code below in your comp SRQM_INCIDENT_H
data:lr_comp_controller type ref to <ur comp controller class>lr_comp_controller ?= me->comp_controller.
    lr_comp_usage ?= lr_comp_controller->get_component_usage( iv_usage_name = '<name of the comp usage as in runtime repository' ).
    CHECK lr_comp_usage IS NOT INITIAL.
    lr_cnode ?= lr_comp_usage->get_context_node( iv_cnode_name = '<the required context node name>' ).

How to populate the context nodes based on an event

Hi All,
I am having a basic problem. I have created a new Webdynpro Abap application. Here, in the main view, i have define a text view as well as a table. I have created context nodes A and B in component controller. The attributes under A are A1 and the attributes of B are B1,B2, and B3. I have also created an action button C in the same view. These have been mapped to the context nodes in the main view. A1 is mapped to the text view and B1, B2 and B3 are mapped to the table.
My requirement is as follows. When user Clicks on execute, i want to use the value A1 from the text view in a function module and return the values to B1, B2 and B3. B1, B2 and B3 are multiple values mind you.
I have successfully executed the function module within the WDONACTIONC method. How to i accomplish this Basic Task. Please Help
Best Regards
Mazin

Hi Mazin,
Step 3 is as follows...
Say you have a context node, you have to bind this node with table UI element, now this node must contain some context attribute which you have to bind with your columns of table. now say name of context node is cn_table. now what you have to do is get data from FM in the internal table..........
now move data by using move corresponding or by looping depending on requirement to an internal table which has fields with the same name as that of name of your attributes... this is imp to display the data...... now you can bind this internal table with context node using code below.......
data lo_nd_cn_table type ref to if_wd_context_node.
data lo_el_cn_table type ref to if_wd_context_element.
data ls_cn_table type wd_this->element_cn_table.
data it_table type wd_this->elements_cn_table.
data wa_table type wd_this->element_cn_table.
data it type standard table of t005t.
data wa type t005t.
**   navigate from <CONTEXT> to <CN_TABLE> via lead selection
select * from t005t into TABLE it.
loop at it into wa.
    wa_table-ca_one = wa-land1.
    wa_table-ca_two = wa-landx.
    wa_table-ca_three = wa-natio.
    wa_table-ca_enable = abap_true.
   append wa_table to it_table.
    endloop.
lo_nd_cn_table = wd_context->get_child_node( name =
wd_this->wdctx_cn_table ).
*   get element via lead selection
    lo_el_cn_table = lo_nd_cn_table->get_element( ).
lo_nd_cn_table->bind_table( it_table ).
ca-one, ca_two, ca_three and ca_enable are name of my context attribute......
regards

Error while generating the context node

Hi ,
Requirement is to add the marketing attribute field under the Account details overview Page. As the field was not available in the context node i have added a new context node in the Account details. I used the wizard and added the context node BuilmktattributeRel so as i can add "Attribute set" under the BP overview page."
Now after adding the context node and while executing i am unable to see the overview view page, i am getting an error :
1. Component GET_ATTRIBUTE does not exist
2. Determination of BOL attributes failed
Also i am unable to regenrate the GET_I_method. If i want to delete the Zcontextnode, i am unable to do so.
Kindly help me with the technical approach to add the context node in the overview page.
Thanks in advance,
Sunil

One thread would have been sufficient.
Error while generating the context node

Reading Attributes from different context nodes in the same view

Hi,
I have added a new field as part of an enhancement for Trade Promotions. This field is a checkbox and part of the context node TRADE in the view TPMOE/HeaderEOF. This field will be checked or unchecked using a logic in the background.
The logic will be based on an attribute (Fund Plan ID) which is part of another context node FUNDPLAN in the same view.
How can I read the attribute of FUNDPLAN context node in TRADE context node?
A sample code will be quite helpful as I am new to CRM 2007.
Thanks,
Abhishek
Edited by: Abhishek Periwal on Oct 16, 2008 2:35 PM

Hi Abhishek,
If I understand your question correctly, you would like to access the Fund plan ID (in a different context node) in the getter setter methods of the check box attribute which you have added.
The code snippet mentioend by sudeep works perfectly fine when you are making any checks in the view implementation class. But since you are in the getter setter methods of the context class, this doesnot work as "me" always refers to the class instance in which you are present.
Now in this case what you need to do is :
1) create an attribute <view_controller> in your context class. Here the context is TRADE. The type of this attribute wud be same as the view controller class CL_TPMOE_HEADEREOF0_IMPL
2) Go to the view controller class and redefine the method
DO_VIEW_INIT_ON_ACTIVATION. This method is called only once when the view is loaded for the first time.
3) In this method, put the following code
me->typed_context->(Trade)->[view_controller] = me.
by the above code, you are setting the newly created attribute to the view controller instance.
4) The next step would be, go back to your getter setter methods or what ever it may be, try referring to the Fund plan ID by the code snippet mentioned below
data: lr_entity type ref to cl_crm_bol_entity.
lr_entity ?= me->[view_controller]->typed_context->[the context node in which the fund plan id is present]->get_current().
lv_field_value = lr_entity->get_property_as_String( **pass the field name here ).
This should definitely resolve the problem.
Thanks,

Retrieve data from other context node within the same context

Hi Experts,
I want to redefine method BUILD_TABLE for a table context node and I need to access data from another context node within the same context. I have looked through the methods of class CL_BSP_WD_CONTEXT_NODE_TV but could not find a mean of retrieving the other context nodes.
Any ideas?
Thanks a lot. Your help is appreciated.

How to populate a context node on the basis of the values in another node?

Hi,
I have a Webdynpro application which has to run on Portal as well as BlackBerry.
In this application I have a scenario where I need to have a sub node inside a node but as Blackberry doesn't support sub nodes with Singleton value false, I have to use another node for storing the values which earlier wre present in the sub node.
The actual scenario here is that we have two tables A & B. For each row of table A we have a no of rows in table B. This can be easily accomplished for Web Browser but we need to do this for Blackberry.
My question here is that how can i populate the data in table B at runtime using the concept of onLeadSelect. I am not able to fully undersans this concept.
According to my approach I have two a while loop which generates data for table A and inside this while loop I have another while which generates data for table B corresponding to each iteration of the outer while loop. I create the node elements for the rows of the table B and store them in a list and then store this list in a HashMap corresponding to a key formed by combining the values of all the elements of the row of table A.
Now I am not able to understand how can I display this data into table on user slecting a particular row.
Please guide ASAP.
It wille quite useful if you can provide me with some code snippets for the same.
Thanks in advance!
Manish

Hi Manish,
In WebDynpro u can use the onLeadSelect event of table A and do all the processing in that method.Like u can use this method to fill ur context node,which will be the source node for table B. So this way u need not to use any hash map.Fill the source node of table B with data corresponding to ur selected data of table A.
I hope this solution wud help u in solving ur problem.

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.

Web Dynpro & Adobe Interactive Forms - how to update the context node

Hi Experts,
I got a WD Component with some context nodes that are mapped to some views and are filled in this views. These context nodes are the dataSource for the Interactive Forms. These forms are embedded in a view by UIElement Interactive Forms.
My problem is, everytime when I change the structure of the context nodes (i.e. there's an additional attribute necessary), I have to design new forms to get the context nodes linked to the form. My existing forms cannot handle updated context nodes.
The change in the context node is displayed on web dynpro side, in the dataSource view in UIElement property. But in TA sfp there is the old context node structure displayed without any change (i.e. in number of attributes).
My forms' layout type is ZCI Layout the interface is based on XML.
How can I easily update the forms' context node structure without creating new forms every time?
Thanks in advance,
Tan

ok, got it.
by double clicking on templateSource in UIElement properties the interface can be updated.

How to map when the Context node has more than one element

Dear SDN Community,
I am develping a WebDynpro java application with Adobe forms. My goal is to present a user a screen with 10 records of customer details and submit. I have created a context element for the customer(Cust#, address details etc) and mentioned the cardinality as 1..n. Now How do I bind these 10 records in my data view to first element, second element... 10th element of the context. Once the user submits, I need to write the 10 record values to Z table. Can you please advice me here.
Thanks!
Surya.

solved this problem by going through the Interactive forms tutorial.

How to make the leaf node of the APEX tree downloadable

Hi All,
I am trying to build a "library" page for my application, with the documents as the leaf nodes of the tree. The documents come from a database table, and each document is a BLOB.
My question is, how should I write the "link" part of the APEX tree query to make the lead node document downloadable for the end users?
Thanks,
Christine

Hilary helped me out of this by creating a new form page with two new items there corresponding to the PK and BLOB column, then in the tree query use apex_util.get_blob_file_src function as the link. Below is the email from Hilary:
1. Created Form, page 13, based upon your table storing the documents as BLOBs. The form page has just two associated items: P13_DOC and P13_DOC_ID. The item P13_DOC is of type FILE and contains a source type of DB column, which is the first required parameters of the function get_blob_file_src. NOTE: I could have created a form region on the same page as your tree, but chose to generate a separate page. You may choose to change this yourself.
2. Updated the Tree query on pg 12 to use the following link for tree nodes of level 4:
apex_util.get_blob_file_src('P13_DOC',v.attr3)
...where P13_DOC is the application page item mentioned in step 1 above, and v.attr3 should hold the unique ID associated with the document. Your tree now allows users to download the listed documents.

I created boolean references in my main vi block diagram and copied them to my sub vi front panel. when wire my reference in my main vi to one the input node of the sub vi the wire is broken. the error says its a class conflict why?

i created boolean references in my main vi block diagram and copied them to my sub vi front panel. when wire my reference in my main vi to one the input node of the sub vi the wire is broken. the error says its a class conflict why?

Expanding and clarifying what BJD said;
After you create the temporary sub-VI that BJD mentioned, open its front panel and copy the reference control that LV created when it created the sub-VI.
This reference control will be correct class etc that you need. Use the control to replace the original control that you were attempting to wire up.
The technique of "create sub-VI...copy" always works for me.
There is one more thing that you should watch out for.
The mechanical action of the boolean can not be set for latch action when attempting to read the value using a value property node.
Trying to help,

Is there a way the user to change the equation in the formular node from the front panel on the fly, dynamically?

Is there a way the user to change the equation in the formular node from the front panel on the fly, dynamically?

Try the Parser VIs (also known as LV Mathematics VIs, or simply GMath VIs) located under the Analyze>>Mathematics palette (not in the Base package). You might want to start with the "Eval Formual Node.vi" located in the Analyze>>Mathematics>>Formula palette. There are many differences between these G-based, dynamic formula VIs and the LabVIEW formula node, but these VIs often prove quite useful when your formula changes on the fly. For more detail on the differences, see the LabVIEW Help file (Cntrl-Shift-? from within LabVIEW) under the topic "Mathematics VIs, parser differences with Formula Node".
