Unhandled property value type 'Kingsland.MofParser.Ast.ComplexValueAst'

[raandree]

The method ParseMofFileInstances throws a NotImplementedException when dealing with instance types.

Exception calling "ParseMofFileInstances" with "1" argument(s): "Unhandled property value type 'Kingsland.MofParser.Ast.ComplexValueAst'"

Do you have by any chance extended the parser?

This is the PowerShell code I am using and below is a MOF file to reproduce the error.

Add-Type -Path $PSScriptRoot\MofParser\Kingsland.MofParser.dll

function Get-MofFileClasses
{
    param (
        [Parameter(Mandatory, ValueFromPipeline)]
        [string[]]$Path
    )

    begin
    {
        $mofClasses = @()
    }

    process
    {
        foreach ($p in $Path)
        {
            $p = Resolve-Path -Path $p
            $mofClasses += [Kingsland.MofParser.PowerShellDscHelper]::ParseMofFileInstances($p)
        }
    }

    end
    {
        $mofClasses
    }
}

$c = Get-MofFileClasses -Path D:\Git\DscBuildHelpersDebug\output\MOF\ClassBasedNode.mof

 ResourceID = "[ClassBasedResource2]2k1::[ClassBasedResources2]ClassBasedResources2";

 ConfigurationName = "RootConfiguration";

Hello. Just a quick reply to let you know I've seen this issue. I'll have a proper look over the weekend and give you an update after...

[mikeclayton]

I've just published a new nuget package - v8.0.0 which is bumped to dotnet 8.

It's also got a new implementation for domain objects (just Instances for now, but potentially Classes, Enumerations, etc at a later date) and a slightly different way of parsing, but it should be a drop-in replacement for what you've got at the moment.

It's not 100% feature complete across the whole MOF spec, but if you give that a go and let me know if there's any problems I'll take another look...

[mikeclayton]

Closing ticket on the assumption the new release fixes it. Will re-open if there's any problems reported...
