Well, that’s for the theory.
In reality, it doesn’t work (for me):
I have this structure...
Res0 (1)
|- Res1 (2)
|- Res2 (4)
|- Res3 (5)
|- Res4 (6)
|- Res5 (7)
|- Res6 (8)
I have 2 calls to GetResources on my page, the first one should retrieve the resources 2,4,5 and the second one should retrieve the resources 6, 7, 8:
[[GetResources?
&parents=`1`
&resources=`2,4,5`
&includeContent=`1`
&includeTVs=`1`
&processTVs=`1`
&tpl=`someTpl`
&sortdir=`ASC`
]]
[[GetResources?
&parents=`1`
&resources=`6,7,8`
&includeContent=`1`
&includeTVs=`1`
&processTVs=`1`
&tplFirst=`someOtherTpl.first`
&tpl=`someOtherTpl`
&tplLast=`someOtherTpl.last`
&sortdir=`ASC`
]]
But both calls retrieve all the resources under (1) ! I tried with or without &parents, I tried different combinations for &resources, but I can’t get it to work :’-(
Edit: no, even worse, I didn’t notice first but for some reason, it only retrieves 2,4,5,6,7 (not

!? This is probably a different "bug".
Edit2: I can’t change the "sortby" property in the property inspector of GetResources, I’m getting a list with two "invisible" items that will clear the property when selected (any), instead of toggling between ASC and DESC.
