I am using ArcGIS 10.1, most recent service pack/patch, and on Windows 7 with 8GB RAM
I always run Models from ArcCatalog
I have a model that validates and runs from the "edit" window.
When I run the exact same model with the exact same input data, but from the "open" window it returns error messages.
Do you have any experience or advice to share over this issue?
Are there certain tools or processes that can cause this issue?
The issue that occurs most frequently is with the Focal statistics and the Get Raster Properties Tools – when the model is run from the Open window these tools can fail because the preceding data does not have valid statistics. It is unclear why the model runs OK (with exact same data) from the edit window. Surely this should be picked up by the model validation process?
The errors that occur are
ERROR 001100: Failed because no statistics are available.
The solution can be to add in "Calculate Statistics" tools into the models, however the behaviour appears erratic and this solution has occasionally not worked, even on the same model , same data, same computer.
One of the models that runs OK from the edit Window, into which I have added the Calculate Statistics tool, return the following error only when run from the Open Window.
ERROR 999999: Error executing function. The workspace is not
connected. Failed to execute (Calculate Statistics).
Any ideas/thoughts?

Whilst preparing this data to send off to ESRI support I did a quick test of copying and pasting the whole model into a new blank Model.
The model now works OK from both Edit and Open windows without adding in any extra Tools / processes.
However this issue - as explained above - happens so frequently that I would be very interested to hear from anyone else reporting similar issues.
For now I have not included the additional "calculate statistics" tools in my model, it remains unclear if the occurrence of these errors messages, and the different behavior between the Open and Edit window is a symptom of an unstable model that is resolved, or if it will re-occur.
