Cannot read an indexed xavp from Kemi-Lua - sr-users

22 Nov 2019


      Hi,
I am having trouble reading an indexed xavp from Kemi-Lua.  The xavp
contains 3 entries but I can only access the first one.  The xavp is the
one filled by the dispatcher module after a call
to  KSR.dispatcher.ds_select(group, 4) with the flags parameter set to 2. I
can get the number of entries using KSR.pvx.xavp_child_get("ds_ctx", "cnt")
which returns 3. I can also get the contents of the first element using,
for example, KSR.pvx.xavp_child_get("ds_dst", "attrs").  But all my
attempts at adding an index value using KSR.pvx.xavp_get()
or KSR.pvx.xavp_child_get() return the value 'nil';
Below is the output of KSR.pvx.pv_xavp_print():
