Summary

0006920: .NET error thrown when a list variable is passed in [ ] to llParticleSystem().

Description

If you call llParticleSystem() with a list that contains a list variable you will see a .NET error in the in-world script error dialog box while the OpenSim console window for the region where the script was running shows an unhandled .NET error.

Steps To Reproduce

#Put the following script in a prim and touch the prim to see the error.

list rules = [];

default
{
    touch_start(integer num_detected)
    {
        llParticleSystem([ rules ]);
    }
}

Additional Information

This problem exists in 0.7.6-post-fixes and in git master.

The error shown in in-world is:
    Runtime error: (6): LSLInteger expected but list given

The .NET message on the console is:
17:52:24 - [SCRIPT INSTANCE]: Runtime error in script New Script, part Linkset test object - 5 coloured prims 0e44bf17-dcee-4a1f-bb23-d99a1ac5f5cf at <217.8448, 158.781, 21.02292> in Welcome Area, displayed error Runtime error:\n(6): LSLInteger expected but list given, actual exception System.InvalidCastException: LSLInteger expected but list given

The script shows an incorrect usage of the LSL function call and should point out the error instead of throwing a .NET exception.
