Load chunk, generate if not existent?

Hi,

I want to make sure a chunk gets loaded, or generated if it doesn't exist.

If I use the following, the chunk generates but there are no ores/trees/tallgrass/etc; there are caves and normal terrain:

worldObj.getChunkProvider().loadChunk(chunkx, chunkz);

How to do it right?

Edit:

Got it, maybe I should look at the functions before I ask next time

For those interested:

worldObj.getChunkProvider().loadChunk(chunkx, chunkz);
worldObj.getChunkProvider().populate(null, chunkx, chunkz);
