I have a tag, say
tableTag, which is of type
Document: it's an array of json objects, all objects with the same structure. I'd like to define some more tags which are expression tags and get their value from
tableTag looking up a value in a key of the
tableTag objects That looks like looking up a value in a dataset, but whereas the expression language has a
lookup function for
datasets, I cannot seem to find an equivalent function for json arrays. I developed a python script function of my own, called
jsLookup and it works. But if I want to use it in an expression tag, my project must be the Gateway Scripting Project and that's not possible.
Any suggestion, except going back to datasets?
