Binding different Context nodes to different Table UI elements dynamicly

[Former Member]

Hello Everybody,

I've a very interesting problem:

I'm getting data from R3 over RFC, and load it into context into the following context structure

Context
|
|- Node_1  //representing the tables on UI
|    |
|    |- Node_2  //representing the rows of table
|    |     |
|    |     |- attributes  // cells of a table
|    |
|    |- attributes  //other infos for a table
|
|-attributes

The data I get, is representing different lists which contains lists and I wanna load into different tables, but the size of the lists are dynamic, so I use the wdModifyView static method.

So I write the code as follows:

    IWDTransparentContainer root = (IWDTransparentContainer)view.getRootElement();
    for (int i=0; i<wdContext.node_1().size(); i++) {
      INode_1Element elem = wdContext.node_1().getNode_1ElementAt(i);
      IWDTray tray = (IWDTray)view.createElement(IWDTray.class, "tray"+i);
      IWDCaption header = (IWDCaption)view.createElement(IWDCaption.class, "tray_header"+i);
      header.setText(elem.getattr_of_Node_1_nr_1());
      tray.setHeader(header);
      IWDTable table = (IWDTable)view.createElement(IWDTable.class, "table"+i);
      table.bindDataSource(elem.node().getChildNode("Node_2", elem.index()).getNodeInfo());
      IWDTableColumn column = (IWDTableColumn)view.createElement(IWDTableColumn.class, "attr_1_column"+i);
      IWDTextView editor = (IWDTextView)view.createElement(IWDTextView.class, "attr_1_editor"+i);
      editor.bindText(elem.node().getChildNode("Node_2", elem.index()).getNodeInfo().getAttribute("attr_of_Node_2_nr_1"));
      column.setTableCellEditor(editor);
      IWDCaption headerAttr_1 = (IWDCaption)view.createElement(IWDCaption.class, "attr_1_header"+i);
      headerAttr_1.setText("ATTR_1");
      column.setHeader(headerAttr_1);
      table.setVisibleRowCount(10);
      table.addGroupedColumn(column);
... //adding other tables the same way

But when I load the page, the same data is in every table UI element. When I export this context to an Excel, it's correct, but the tables seems to be binded the same node.

Please help me ASAP!

Thanks & Best regards:

Hi,

Try to set the leadselection after this line

INode_1Element elem = wdContext.node_1().getNode_1ElementAt(i);

wdContext.node_1().setLeadSelection(i);

First of all Thanks for quick response.

Unfortunetly this didn't help me. The only thing changed that the data in tables is the last nodeElem of Node_1 instead of the first one.

Any other idea?

It's not possible to bind tables to such nested (non-singleton) subnodes. You will always get the child node data of the lead-selection in the outer node.

And is there any way to solve this problem? Maybe reorganize the context? Or tricking with leadselection? It would be great to solve this problem in WebDynpro.

You could "solve" it by creating separate nodes on root-level for each (Node1-element, Node2) pair of the nested node structure. Then you could bind tables to these new nodes.

Wow!

It sounds a big waste of time! You mean that I should create the different nodes dynamicly, than I'll be able to bind this nodes to dynamicly created tables? Is there any tutorials that can be a good point to start this process?

Thank you very much for your idea. I was able to generate the nodes and tables dynamicly. It's not a nice code, but I had to walk this way

Thanks again & regards:
