Check if row exist in the table

Hello, im having some trouble with my table, basically i have a array where are stored the rows that have errors, and all this checking is made on “afterValidate” method, and is working fine, the problem is after i save the data to the server and load again, all the invalid fields gets wiped out and load it again on the handsontable. but after i cant update the errors array, and this is because when i had the table with 15 rows, after loading again the tables goes to 10 rows, so “afterValidate” cant check if the last row is valid because it doesnt exist, so the erros gets kept in the array errors. Is there a method that is possible to check if a specific row index exist on the table?

Hi @geral
I would need to see an example but as I understand you want to perform an extra validation after the data is loaded?
