hello everyone and @volkanceylan
First I explain what I have implemented
On the selection of BOM all characteristics will be display in the above grid i.e. characteristics constant
and by selecting any Characteristics Constant the SubCharacteristics will be display in next grid i.e. characteristics value and after selecting the value both characteristics and its value will be display in third grid to ensure that how many characteristics selected against that BOM
TILL HERE everything is working as I expected
But when I selected more than 1 characteristics Value and delete one of them and again when I select that same value which I deleted then Its shows notification that this value is already selected. Here am unable to refresh grid and also do not understand which grid should be refresh.

Please help me with this!

@jmkamran ,
again - stop spamming the issues of others here in the Serenity forum with plain advertising for your youtube channel when your linked youtube video does not at least solve a considerable part of the asked question.
The linked youtube video only shows how to add dfaruques serenity.extra - but this does not - in no wise - solve the asked question.
If you continue like this I will consider reporting your activities as abuse.
With kind regards,
John
@Shraddha996 Did you solve your issue ? Also You stated the things you had were working as expected - I certainly would like to see an example of that - as I am trying to implement the same thing.
