Should I get a string in the context variable when I use: Context["RECIPETYPE"] = "@{Document.type}"; in a script?

karl_harris_ — Mon, 09 Apr 2012 17:46:38 GMT

When I try to set a context variable using: Context["RECIPETYPE"] = "@{Document.type}"; I get the error below.

If I use Context["RECIPETYPE"] = "ThisIsATestString"; everything downstream from this script line works ok.

Error log output:

Did you mean that you add a Execution Context > Set Context Variable operation into you operation chain definition and you set values like this:

name: RECIPETYPE
value: @{Document.type}

Because if you do

name: Context["RECIPETYPE"]
value: @{Document.type}

You ask to automation to get the name where store the document type value into the RECIPETYPE variable.

Anyway your error is not at all expressing value you set. Did you put something like that in your chain:

@{Fn.getVocabularyLabel("voc", "key")}

The problem is more there.
