You can use the Dictionary Utilities and use dictUtil_merge to merge the dictionaries.

I've accomplished this effectively using these three expression rules:

extractKeysFromDictionary:

a!forEach(
  items: xpathsnippet(toxml(ri!dictionary), "/*/*"),
  expression: index(split(index(split(fv!item, " "), 1), "<"), 2)
)

extractValuesFromDictionary:

a!forEach(
  items: rule!extractKeysFromDictionary(ri!dictionary),
  expression: property(ri!dictionary, fv!item)
)

combineDictionaries:

reduce(
  fn!insert,
  ri!dictionary1,
  merge(
    rule!extractValuesFromDictionary(ri!dictionary2),
    rule!extractKeysFromDictionary(ri!dictionary2)
  )
)

I think you can create new Dictionary by passing this existing dictionary using foreach() or apply

Hi Mike,

Thanks. I have in the meantime however come up with a solution that doesn't require any additional plugins. See below:

with(
  local!dictionary: cast('type!{http://www.appian.com/ae/types/2009}Dictionary', {}),
  local!fields: {"field1", "field2"},
  local!values: {"value1", "value2"},
  reduce(
    fn!insert(_, _, _),
    local!dictionary,
    merge(
      local!values,
      local!fields
    )
  )
)

Kind Regards,

Philip Snyman

You probably need to look into the CDT Manipulation plug-in, which has the "JoinCdts()" rule, which based on the limited detail you've provided, i'm guessing is your closest bet.

Also, AFAIK a!flatten() doesn't handle this use case - it is more for creating a single flat array of results when using looping functions might return arrays of arrays which can be confusing to deal with.

You can try using a!flatten().
