B4J Question Populating B4X Table...

rbghongade · Aug 22, 2019

Hi,
How to populate the cells in B4X Table from a generated array or list?
I have created a list named "op" containing string type data.
When I use

B4X:

B4XTable1.SetData(op)

I get the error:

B4X:

java.lang.ClassCastException: java.lang.String cannot be cast to [Ljava.lang.Object;

Thanks,
Had already seen the example posted in the link, but getting the runtime error!

you are giving a string, not a list.

java.lang.ClassCastException: java.lang.String cannot be cast to [Ljava.lang.Object;

so in your case

B4X:

B4XTable1.SetData(op)

op seems to be a string?

op is a list as i have populated it with :

B4X:

op.Add(y)

where y is a string generated with "NumberFormat" in a loop.

Finally sorted out! Thank you guys!
I missed:

B4X:

op.Add(Array(y))
