I am using the JAI.create and in fact I thought the TileCache should be used by default. I also used the method you report above to specify the tilecache and also set some more memory to it in order to be sure that it is ok. But nevertheless also with very small images the thing got triggered more than once. But now that you take away my doubt about how it should be, I will try to see if I can find where I do something wrong. > If you really have a TileCache, check if it is full (there is methods in > TileCache interface for checking the amount of bytes used). TileCache is something I would like to implement with a "geomorphologic knowledge" at some point, but before I want to make sure that the rest of things work :) Thanks and congratulations for your (& friends) job on geoapi at OGC.
