B4J Question create a map object at runtime

[bvonlaar]

Hi all,
I have a set of coordinates (type marker) which are kept in a map for changing/removing the set marker anytime. This is done by MMap.put(i,m).
But I have further sets of coordinates. I thought I could create a Container map like MMapCon(ii,MMap) as a kind of parent. The result is, that it seems that I got only the last one, which was set to MMap. So I think I need something like MMap(i), but I don´t know whether the creation of a new map object at runtime
is possible.

Am I right and any idea how to do?

You can have a look at https://www.b4x.com/android/forum/threads/class-nestedmap-a-map-in-a-map-with-n-levels.76163/ maybe it suits your needs !

I checked it and it sounds interest, but your way is quite complex ;-). It could match what I´m looking for.

Sounds like you haven't dimmed and initialized the map before you reused it.

No, I made another mistake. I found it last night. The container maps indices start at 0 but the reference entrance start with 1,2,3....
So I had a trigger problem to sychronize all maps and tables. But particial you are right when I review my steps then there was also one time
an initialisation problem, but it wasn´t the only problem .

Much thanks, the problem is solved!!
