Loading data issues

[Mandraval]

Perhaps someone can explain to me, what I am doing wrong...

Loading data worked right fine for some time, but since the amount of data got quite huge, I tried to split these data to various files on disc.
Loading works quite fine, except it takes ages (and sometimes leads to server-disconnects for too long loading time).

So I tried to split the loading between startup and runtime.
If I load all data at startup, there is no difference, but if I try to load some data during runtime, the load routine finishes, with no data returned.

dataload=VindarPatch.PatchDataLoad(Turbine.DataScope.Server,"filename",load_done)

If this code is executed during load, dataload contains the requested data.

Perhaps I'm getting this wrong, but I think, 'load_done' should be called when the data was loaded, and if I try to access the data in the function load_done, it is always >nil<

function load_done()
	if(dataload~=nil) then

dataload should be known in both functions

Any help on getting the data loaded?
