Hi Karthikeyan Ramasamy,

Still I am not getting Result. It is s showing Internal Server Error. Is it the way to declare node and attribute in wdDoModifyView. Is it necessary to declare in the wdDoInit Method.

Thanks,

Hi Ashvitha,

It is working fine for me. please check the other codes which are written in DoInit and DoModifyView or can you post your DoModifyView code here?

Hi Ashvitha

It is very late reply...I was getting also same problem.This error is because of Caption..If u comment that caption whole line then ur programm will run but without column name .My NWDS version is 7.0.0.Here the caption is not taking. is showing Internal Server Error.If u deploy in different version NWDS then it will definitely work.Just check.

Hi,

Have look at the following sample code. and try it with your own data. this will create a table and context node and attributes for that table dynamically.

IWDTransparentContainer rootElement = (IWDTransparentContainer)view.getRootElement();

IWDNodeInfo tabNode=wdContext.getNodeInfo().addChild("Tab_Node",null,true,true,true,false,true,false,null,null,null);

IWDAttributeInfo tabAttrib_Name=tabNode.addAttribute("Name","ddic:com.sap.dictionary.string");

IWDAttributeInfo tabAttrib_Add=tabNode.addAttribute("Address","ddic:com.sap.dictionary.string");

IWDTable tab=(IWDTable)view.createElement(IWDTable.class,"Dyntable");

IWDAttributeInfo attrib1=tabNode.getAttribute("Name");

IWDAttributeInfo attrib2=tabNode.getAttribute("Address");

tab.bindDataSource(tabNode);

tab.setCompatibilityMode(WDTableCompatibilityMode.AUTO);

tab.setDesign(WDTableDesign.ALTERNATING);

IWDTableColumn tabColumn1=(IWDTableColumn)view.createElement(IWDTableColumn.class,"NameCol");

IWDTableColumn tabColumn2=(IWDTableColumn)view.createElement(IWDTableColumn.class,"AddressCol");

IWDCaption nameCap=(IWDCaption)view.createElement(IWDCaption.class,"nameCap");

nameCap.setText("Name");

tabColumn1.setHeader((IWDCaption)nameCap);

IWDCaption addCap=(IWDCaption)view.createElement(IWDCaption.class,"addCap");

addCap.setText("Address");

tabColumn2.setHeader((IWDCaption)addCap);

IWDInputField nameText=(IWDInputField)view.createElement(IWDInputField.class,"nameText");

nameText.bindValue(attrib1);

tabColumn1.setTableCellEditor((IWDTableCellEditor)nameText);

IWDInputField addText=(IWDInputField)view.createElement(IWDInputField.class,"addText");

addText.bindValue(attrib2);

tabColumn2.setTableCellEditor((IWDTableCellEditor)addText);

tab.addColumn(tabColumn1);

tab.addColumn(tabColumn2);

tab.createLayoutData(IWDRowHeadData.class);

tab.setWidth("300");

IWDNode dynTabNode=(IWDNode)wdContext.getChildNode("Tab_Node",0);

for(int i=0; i<5;i++)

{

IWDNodeElement dynTabElem=(IWDNodeElement)dynTabNode.createElement();

dynTabElem.setAttributeValue("Name","Karthik");

dynTabElem.setAttributeValue("Address","Chennai");

dynTabNode.addElement(dynTabElem);

}

rootElement.addChild(tab);

// you should create one action for the table lead selection

IWDAction tabact=(IWDAction)wdThis.wdGet<Actionname>();

tab.setOnLeadSelect(tabact);
