getInstance method of Provider is not called

[aathif]

HI, I seem to have  a weird problem. I have registered a server for a sample CIM Class, which is also displayed on the CIMWorkshop tool. When I click on the 'Show Instances' menu the Instance Editor opens up & the instances are displayed except for thier properties and their values.
What I noticed from the console log is that the enumerateInstanceNames method of my provider was called. But the getInstance method is not getting called.
The log for enumerateInstanceNames ..

Iam unsure why my Providers getInstance is not being called here/

Hi,
It was a mistake in my provider code. The enumerateInstanceNames method was not setting the keys in the CimObjectPath to be returned. I used the CIMobjectPath.setKeys method to set the keys and it is working fine now :)
