hi
i just encounter a really weird behavior. i am not sure it is related to the new update or not.
so what i did is adding each letter in a specific text to a clv.
i add only a single view. it is a label.
i made some speed test and i had big differences between 2 methods.
method 1:
so i create inside the function a nativelabel and reference it to a b4xview.
this method works fine and fast.
then i tried to add the label from a outside function to be able to use it again.
like this:
this method took much longer (x50 longer)
1. method (in debug mode) 80ms
2. method (in debug mode) 4000ms
so first i thought it has something to do with creating the label from outside BUT accidentally i changed the outside method to NOT use the passed variable and it took the same time as the 1 method like this:
as you can see EVENT is not used and it takes now only 80 ms as the first method. why is it like this that if i used the passed object it takes 50x longer to create this clv than not using the passed object??
