Hello, does anyone know if there's a reason why

getLineCount()

returns 0 for User Event in view mode? I'm trying to pull lines of sublist that consists of custom records. I get correct amount of sublist items in edit mode, also I still can pull list of sublists of parent record in view mode anyway.

I've been frustrated by that in the past as well and have yet to figure out a reason for it. My workaround is to load the record in view (using N/Record) to get line counts but that feels like an otherwise unnecessary database hit compared to create/edit modes (with all of the related performance impacts, etc.).

When you say view mode I assume you mean

beforeLoad

entry point?

beforeLoad

is my use case, yes. An example of why I've wanted to get line counts in `beforeLoad`/`view` is to disable buttons based on whether or not a particular sublist has any entries in it.

@MTNathan I understand but according to the

beforeLoad

help: • Data cannot be manipulated for records that are loaded in beforeLoad scripts. If you attempt to update a record loaded in beforeLoad, the logic is ignored.

I'm not trying to update anything in the sublist though (or elsewhere on the record), just trying to read data from it (the same way you might use the value in a field in

beforeLoad

to adjust the form, which is definitely supported). A search is a good alternate suggestion, though I don't know if that's better for performance than a record load.

@alien4u correct, I meant

beforeLoad

entry point. Even if record is loaded in read-only mode, personally I see no reason why that data could not be available. @MTNathan was trying to do the same thing as it turns out

@MTNathan There is no significant difference from a Search to a record load, in some cases a search is faster than loading a record.

@alien4u That's what I figured, thanks for confirming. I guess at that point it would come down to whether you need info about a single sublist or multiple - loading the record gets all of the sublists so that could avoid multiple searches, but if you only need one then maybe searching is preferable.
