To populate values in Table

[Former Member]

Hi,

I need to populate values in a table which i got from the bean...

i have retrived the values in Class[] and if i populate the table (as in code below).. i get only the first record..

i have created a value node (GroupNode) in the view context and iam binding the values to it from my Java Command Bean (CategoryBean)..

The code is as follows..

GroupDTO[] groupDTOs = wdContext.currentCategoryBeanElement().modelObject().RetSameCatidObj();

// Collection groupList = new ArrayList();

for(int i=0;i<groupDTOs.length;i++){

groupList.add(groupDTOs<i>);

IPrivateDel_sda.IGroupNodeElement ele = wdContext.createGroupNodeElement();

ele.setCategoryid(groupDTOs<i>.getCategoryid());

ele.setGroupid(groupDTOs<i>.getGroupid());

wdContext.nodeGroupNode().bind(ele);

}

Is there any workaround to solve the issue...

Thanx.

Hi,

I got it resolved by binding the table to a newly created node with all attributes as b4... nw it worked ,,,...

thanx for all ur replies ..

thanx 4 ur time..

Hi,

Instead of statement

wdContext.nodeGroupNode().bind(ele);

please use

wdContext.nodeGroupNode().addElement(ele);

[Former Member]

Replace

wdContext.nodeGroupNode().bind(ele);

by

wdContext.nodeGroupNode().addElement(ele);

this my code which gives first record in the table

wdContext.currentCategoryBeanElement().modelObject().setCategoryid(wdContext.currentGroupbeanElement().getCategoryid());
GroupDTO[] groupDTOs = wdContext.currentCategoryBeanElement().modelObject().RetSameCatidObj();
for (int j = 0; j < groupDTOs.length; j++)
{
  IPrivateDel_sda.IGroupNodeElement ele =  wdContext.createGroupNodeElement(); 
  ele.setCategoryid(groupDTOs[j].getCategoryid());
  ele.setGroupid(groupDTOs[j].getGroupid());							
  wdContext.nodeGroupNode().addElement(ele);
}

thnxs 4 ur reply

How many elements does the array contain?

Hi,

The number of elements in the array is 6 fields..

but i need to show up only two fields in the table view..

Thanx,

Please post the exact context structure including cardinalities. The code looks ok to me.

Hi,

the context has following elements to it...

node name:GroupNode

node Elements:categoryid,

groupid,

groupname

message,

status,

updatedby,

lastupdatedby

cardinality:0-n;

selection:0-1

do we need to use iterator methods to iterate between the records....

thanx..

With "node elements" you mean attributes, right?

Use the debugger to check how many elements the node "GroupNode" contains after the loop. What do you get?

Armin

[Former Member]

Hi,

I debugged the code and found that groupNode has two records for it...

but in the table it shows only first record on the UI..

Thanx.

You are confusing me. First, you said that the array from which you fill the node contains 6 entries, then you say the node contains 2 elements and the table shows one entry?

Please check again:

- How many entries has the array from which you fill the node.

- How many elements contains the node after the loop?

- How did you bind the table against the node?

- Did you invalidate the result node after executing the backend call?

Hi,

My Node has 6 elements but iam populating only 2 elements (groupid and category id) to the table..

So number of node elements is 6 only when i debugged...

1) Array has 6 elements..it has only 2 records in db against it...

2) 6 Elements after the loop..

3) i have created a value node and i bound that view context value node to the table..

4) I am using EJBs to get the values from database...

thanx.

If we do not use the same language we will have trouble in communication.

In Web Dynpro we talk about context nodes, attributes and node elements.

You say "My node has 6 elements". What does that mean, 6 attributes or 6 node elements?

"Array has 6 elements, it has only 2 recors in db against it". I don't understand this sentence.

Please clarify.

Hi,

Sorry for not following the conventions...

My node has 6 attributes to it...

The array has 2 entries

[0] ={ grpid = "user 1" , gname ="gname1" , catid= "cat1",status="current",lastupdate = "18/1/08",updatedby = "user1"}

[1] ={ grpid = "user 2" , gname ="gname2" , catid= "cat2",status="current",lastupdate = "18/1/08",updatedby = "user1"}

Thanx.

Thank you. So the remaining problem is that your table shows only one row but the data source node contains 2 elements?

Can you please tell in which method you are filling the data source node and how the data-binding of the table looks like?

Hi,

The code which i posted before is the code i wrote in onactionshow method of a button...

I thought this is sufficient to populate the table as i have bound the values to the context...

Is there any more to populate the values in table...

Actually iam new to this java developement, as i am a abap developer by prof..

Thanx.

Shravan.

The code looks ok to me. Which value has the "visibleRowCount" property of the table?
