Event Handlers/Action Chains triggered on new document contained in folder vs workspace!?

[karl_harris_]

I have at least three different (using a similar configuration pattern) Event/Handler/Action Chain pairs working to fill out fields in newly created folders and documents extended from folders.

I cannot get a similar Event Handler/Action Chain pair working when creating a document in a workspace.

Are there any subtle differences with respect to Event Handlers/Action Chains between folders and workspaces that I should be addressing?

The symptom is the document context,created in the workspace, is not passed to the action chain when the chain is fired so I can't manipulate the field entries. The action chain is a carbon copy of the one working on folders. The chain does fire, the context is not available.

Hope this example clears up what I'm trying to do.

Action Chain Example: (Content view query):

ecm:mixinType != 'HiddenInNavigation' AND ecm:isCheckedInVersion = 0 AND ecm:currentLifeCycleState != 'delete' AND ecm:isProxy = 1 AND ecm:primaryType = 'ZCtrlDocument'

I get a single document from this query. Yes, it's in a section and published. I just want to read some of the meta data first then put that data into the document being created.

Here's the test action chain that's fired from my User Action:

FETCH -> UI SELECTION USER INTERFACE -> ADD INFO MESSAGE value: expr:@{Document["dc:title"]}

that's it!

I get the following:

Caused by: [Error: could not access: Document; in class: null]
[Near : {... Unknown ....}]

Can you please be a bit more precise of your chain/Event handler configuration. You can just edit your question this will be more readable.

[Benjamin_Jalon1 · Accepted solution]

I just copy what Alain told me to copy here 🙂

Actually, I think that your null pointer exception is for the object "Document". What you should do is, just after the Fetch Selected Documents, to run an Execution Flow > Run Document Chain. The reason is that the "Document" object is not available when the input is "Documents".

You can see a sample of this at the page 99 on the following slides

A stacktrace would help to make sure of what is null.

Hope this answer will help you.

Duh, sorry for having to repeat the answer.

No problem, this is just because I'm not expert as Alain is
