FlushParentHashtable "trouble"

[Sgqvur]

What does FlushParentHashtable native actually do? I thought it just clears/flushes whatever was in the hashtable passed as an argument but it seams it renders it unusable.

globals
    hashtable ht = InitHashtable()
endglobals
    
function test_flush_parent_hashtable takes nothing returns nothing
    call SaveInteger(ht, 0, 0, 100)
    call BJDebugMsg(I2S(LoadInteger(ht, 0, 0))) // displays 100 (no surprise)
    
    call FlushParentHashtable(ht)
        
    call SaveInteger(ht, 1, 1, 200)
    call BJDebugMsg(I2S(LoadInteger(ht, 1, 1))) // displays 0? why??
endfunction 

function InitTrig_test takes nothing returns nothing
    call test_flush_parent_hashtable()
endfunction

It's like destroying a hashtable. You have to re-initialize it.

Hm... well that's strange. But I guess I shouldn't be surprised because Blizzard made
hashtables to replace "the good old" gamecache and with them you also need to reinit
it after flushing (FlushGameCache).

Use:

native  FlushChildHashtable					takes hashtable table, integer parentKey returns nothing

Instead. It will flush all the data stored under 'parentKey'.
