Trying to load all items gives an OutOfMemoryError after 155 ms or 5835 items...

*** Service (starter) Create ***
** Service (starter) Start **
** Activity (main) Create (first time) **
Call B4XPages.GetManager.LogEvents = True to enable logging B4XPages events.
** Activity (main) Resume **
Index time: 155 ms (5835 Items)
java.lang.OutOfMemoryError: OutOfMemoryError thrown while trying to throw an exception; no stack trace available

The load of the limited 500 items (there's a test for the debug mode #if debug) works fine.

Index time: 36 ms (500 Items)

The filling of the list probably needs some lazy loading... i try to look into it...
@Erel doesn't recommend using BBCodeView with large...

@Erel doesn't recommend using BBCodeView with large datasets:

The generated bbcode text can get quite large. I wouldn't use BBCodeView like this with a larger dataset.

I have added a new page in my CLV examples tutorial.
The page shows how to use a CLV with lazy loading.
It uses your tambon.csv file.
