How can I add components dynamically to a container in specific order in codenameone?
I am creating a UI dynamically from a json object. I will like to add components dynamically to a container according to a specific sequence. I have tried to use
Container cat = new Container();
cat.add(i,comp)
where i is an integer index and comp is a component. I get an error that layout does not accept index parameter. I have tied with BoxLayout and FlowLayout but something. So is this method signature wrong ab initio o what? What is the right way to add components in a given order dynamically?

This version of add maps to the constraint parameteradd(Object, Component)due to autoboxing the offset is turned into an object which doesn't fit here... As Diamond saidaddComponent(int, Component)will accept an offset. Notice that by default all methods add to the end

// Try adding at a specific location and if that fails, add normally as the last component
try {
cat.addComponent(i, comp);
} catch (ArrayIndexOutOfBoundsException ex) {
cat.add(comp);
}
