selection cardinality does not allow multiple selection

[former_member205624]

Hi, friends

I am trying to select multiple rows in a table but getting that error.

<b>com.sap.tc.webdynpro.progmodel.context.ContextException: Node(ResultView.Bapi_Po_Getitemsrel_Input.Output.Po_Items): selection cardinality does not allow multiple selection</b>

I have set all the required properties. Like selectionMode = multi

cardinalty = 0..n

selection = 0..n

Please some one help me out.

Thanks in advance!

Check the selection cardinality of all nodes from the table data source via mapped nodes etc.

Start with the node in the view controller. If it is a mapped node, go to the mapping origin in the custom/component controller etc.

Open the context editor for each controller and check the selection cardinality for the corresponding context node.

Hi Jitender,

I am not sure whether the Singleton property would change the behaviour. Please check..

Hai,

I tried this by changing the cardinality to o..n and selection mode multi.

but i dont get message as well as i dont get any effect of multi selection.

check also that the cardinality and selection properties (0..n and 0..1) are set for the corresponding controller context as well.

What is the node that you had bound the table to?

Make the "selectionMode" property to auto*.

When are you getting this error? while build/deploy/run?

Thanks and regards
