How to Implement the OVS in a table

Question

Hai
I want to implement a table with one column with OVS. But if I want to enable OVS, I can not create a table because of the cardinality of the node-element of the context.
My table Node cardinality  is 0..n because we have many rows in a table.
i have introduced EVS in one column.it works fine.
Because We can not set our own inputfield or button in EVS Pop Up.
If we select the cardinality "1..1" the OVS works but the table only can have one row.  If we select the cardinality "0..n" the table can have "n" rows but the OVS is disabled.
Did anybody implements a similar application? Please help
i got the following error
When i call WDValueServices.addOVSExtension with ovsStartupAttributes, do this error: MappedAttributeInfo ViewName): must not modify the datatype of a mapped attribute

Hi,
If you think it's cardinality issue thenchange it to 1:n.
Otherwise do like this.
Create a custom controller first say OVSCustomController
and do following things for a column:-
Add this controller in your view.
IPublicOVSCustomController.IContextNode  ovsContext = wdThis.wdGetOVSCustomControllerController().wdGetContext();     
Create input and output nodes for ovs.
IWDNodeInfo ovsInputNodeInfo = ovsNodeInfo.addChild(columnName+"Input",null,true, CMICardinality.ONE,CMICardinality.ONE_TO_MANY, true, null);     
IWDNodeInfo ovsOutputNodeInfo = ovsNodeInfo.addChild(columnName+"OutPut",null,true, CMICardinality.ONE_TO_MANY,CMICardinality.ONE_TO_MANY, true, null);
Create Attributes for this field in the input and output nodes.
IWDAttributeInfo attrInputInfo = ovsInputNodeInfo.addAttribute(field,datatype of field);
IWDAttributeInfo attrOutputInfo = ovsOutputNodeInfo.addAttribute((relatedfield,datatype of field);
set the attribute Info array:-
IWDAttributeInfo[] attrInfoArray = new IWDAttributeInfo[1];
          attrInfoArray[0] = attribute info of the column
Now call the ovs service :-
WDValueServices.addOVSExtension("",attrInfoArray,ovsInputNode,ovsOutputNode,listener);
Your ivs window will be opened by this.
Feel free for any queries regarding this.
