Soap issue, get_relationships, ProspectLists->Prospects

[bnp]

Hiya all, new to the forum and hope someone might be able to clarify this issue for me.

I'm trying to retrive the Prospects for a particular ProspectList like this

get_relationships_result prospects = SugarComm.get_relationships(varSessionId, "ProspectLists", varProspectListId, "Prospects", "", 0);

But the line fails with an error that roughly translates to "the server did not return a meaningful answer"

Now i do't have any problems getting relationships for Campaigns -> ProspectLists, or other relationships i've tried, just this one so I am a bit puzzled about it.

the Sugar is Version 5.0.0b (Build 3150)
I've looked through the changelogs for the c, d and e patch but not seeing anything that looks related, i'm still going to ask to get the server patched though.

the relationship seems to be defined in sugar's table relationships.

my client is done in .Net3.5 C# using a generated proxy object.

So anyone run into this issue before? maybe got a solution? suggestions?

Thanks in advance,
bnp

it seems that the Prospect.php file doesnt get included and therefore isn't available at the point where get_relationships attempts to create the class. A hack that seems to solve the problem is to simply hardcode

"require_once('modules/Prospects/Prospect.php');"

directly in the soap.php file. not exactly optimal, but it looks like it gets the job done.
