Error loading Node.Metadata

Hi!

I have a C# program, with which I want to change some attribute values of CS objects. I try to get an object via CWS then change it and save again. But when I use DocumentManagementService.GetNode, I get the following error:

Error loading Node.Metadata

 

Server stack trace:

I traced an error source to OpenText.Livelink.Service.DocMan.dll. In it's logs the error is:

2016-04-15 15:28:48,6992 ERROR [10] Error loading IntegerValue.Values

2016-04-15 15:28:48,6992 ERROR [10] Error loading AttributeGroup.Values

2016-04-15 15:28:48,6992 ERROR [10] Error loading Node.Metadata

 

It looks like the code tries to read an Integer value, but can't for some reasons. Now, one of our attributes has a string value, but it turns out that our custom OScript logic writes an Integer value to it. If I change the type of this attribute, the GetNode method works correctly, but it works only with new objects. If I press "Upgrade" button in old objects, then GetNode works too, but the value of an attribute is lost. 

What can I do to fix this error with old objects?

Hi

I've faced same error. In my case it was because of Real type category attribute. Lets say you want to set Real type category attribute in OScript to zerro. You should use 0.0 (zero dot zero), because it is Real type. If you try to set this attribute to 0 (zero without dot zero) OScript will allow you to do that without any errors, but in database table this value will be set as 0 (zero) instead of G0. In llattrblobdata table Real type stored as G0. Feel free to contact me https://twitter.com/Pavel_Evdokimov
