Disable sorting on one column only in a paging grid

@roopeshr/harshav Hi, so I guess I am back with a solution. It might seem crazy to you but please do take a look at the code snippet attached here and try to improvise it as I have written it quite quickly. I have tested it and it worked like a charm for me.

In short, I guess we can eliminate the error by handling the pagingInfo variable when there is a blank value or invalid value provided for the field which can be either intentional or by mistake.

Below is the code at a high level and let's see what the community opines:
a!save(
local!pagingInfo,
a!pagingInfo(
startIndex: if(isnull(save!value.sort),local!pagingInfo.startIndex,if(length(save!value.sort.field)<=0,local!pagingInfo.startIndex,save!value.startIndex)),
batchSize: if(isnull(save!value.sort),local!pagingInfo.batchSize,if(length(save!value.sort.field)<=0,local!pagingInfo.batchSize,save!value.batchSize)),
sort: a!sortInfo(
\ tfield: if(isnull(save!value.sort),local!pagingInfo.sort.field,if(length(save!value.sort.field)<=0,local!pagingInfo.sort.field,save!value.sort.field)),
\ tascending: if(isnull(save!value.sort),local!pagingInfo.sort.field,if(length(save!value.sort.field)<=0,local!pagingInfo.sort.ascending,save!value.sort.ascending))
\ t)
)
)
