All Elements Of Category fails for views

[andydandy74]

Using All Elements Of Category on the Views category will results in the following warning:
Warning: ElementQueries.OfCategory operation failed. View cannot be a template view.
The same happens when using All Elements Of Type

[andydandy74]

Fun fact: in 0.6.3 this used to work...
I had a go at this using a Python node in 0.7.x and noticed that the warning/exception is thrown when converting the FilteredElementCollector to actual Revit elements using the ToElements() method. Strangely enough, it is not possible to catch it using try/except or even going through the iList of the collection one by one and catching it on a per-element basis. I don't really know what to make of this...

Its because of the new Revit API that now includes view templates in a view category. I wrote a node for this: http://archi-lab.net/?p=1074
You just have to check if view.IsTemplate and exclude that from search.
Good luck!

[andydandy74]

No, @ksobon , that can't be the reason. When I try this on top of Revit 2014 with 0.6.3 it works and with 0.7.3 it doesn't. So obviously it's Dynamo, not the Revit API. It seems like Dynamo 0.7.x is handling (some) warnings/exceptions differently.

You are both correct. @ksobon is correct that the template view thing is causing headaches, and @andydandy74 is correct that this worked in 0.6.3. We changed the way that we do this filter collection in 0.7.x and didn't account for the new functionality that throws this exception.

any update here? still there in RC2 0.7.5.

[billingsgr]

I have Dynamo 0.8.0.950 and this is still an issue? How do we deal with this View Template Error?

[jbenoit44]

Still an issue in 0.8.2.1601.

[ksobon]

Mhmmm, can we get this solved? It would be nice. Thanks!

Duplicated by #2313

@ikeough Still an issue in 1.0.1 on Revit 2016 r2. Can we get this solved. It looks like its been around for a while now.

[ParametricMonkey]

@ikeough @kronz Can someone have a look at this please

[kronz]

We'll get his for 1.2. Sorry, this one fell between the cracks.

[QilongTang]

A fix attempt is made, see Pull request as reference: DynamoDS/DynamoRevit#1239

[sm6srw]

Fixed in 1.2.

[ikeough]

👍

@kronz @ikeough I'm running Dynamo v1.2.1.3083 and I am still getting this problem. I thought this had been fixed? It works sometimes but not others and i can't work out why

[ParametricMonkey]

The warning is slightly different thought; "Warning: ElementQueries.OfCategory operation failed.
The managed object is not valid."
