Index Error When Deleting Grid Row

Question

Hi - I am receiving the following error when deleting a row from my grid. It is not throwing the error when working in the interface designer and the index claimed as invalid does exist. 
 
 Expression evaluation error in rule 'xyz_dateinfogridrowlayout' (called by rules 'xyz_entermiscinfo' > 'xyz_enterclinsslins') at function a!applyComponents [line 59]: An error occurred while executing a save: Expression evaluation error at function 'remove' [line 87]: Invalid index (1) for list: valid range is 1...0

Hi danak451 you can follow below mention procedure to resolve this issue: 
 
While declaring a!applyComponents() perform a null check as 
 
if(rule!APN_isBlank(local!my data), {}, your logic to enemurate) 
 
This will avoid iteration over the empty set of rows which do not exist post removal. 
 
Hope this will help you, if not, it's better if you can attach the code snippet here.
