Checking for Validity of Design Results via RAM DataAccess

Question

I'm trying to check if the Beam and Column design results are valid. I see that I can use "IModelStatus1.DesignIsValid IAmRamSteelColumn, bDesignIsValid" to get the status of the design module, but it seems the value of bDesignIsValid is always returned as "4" (It returns a Long, contrary to what the Manual says). 
 Strangely, this does appear to work for columns as "IModelStatus1.DesignIsValid IAmRamSteelColumn, bDesignIsValid" returns a value of "1" when designed and "0" when not designed. 
 Is this functionality simply broken for IAmRamSteelBeam?? 
 Is there any other way to check if results are valid? I'm trying to avoid making calls that will error out and instead just put my code behind if statements that check for validity first. 
 
 Thanks! Tim

There is an undocumented method in IModelStatus called GetLightFor that returns module_status_light. I have never used it. Please note, you might need to consider grey (no relevant members) in addition to green. Whenever I have needed to verify model status for DA tools that I have created, I have always used IModelStatus.WhatsMyStatus. I would have to run some tests, but I suspect LIGHT_IS_GREEN and ModIsVALID are essentially the same thing.

There appears to be a bug with IModelStatus.DesignIsValid. I will investigate further and log a defect. To work around the issue, try using IModelStatus.WhatsMyStatus. This returns a model_status enum for the module status. Checking to see that the value is ModIsVALID (or 1) would appear to meet your needs.
