Is it possible to reference a master item from a qlik-visual component instead of hard-coding the measure formula in a mashup? I would like to use the Qlik application to define the measures and dimensions, and then refer to these master items as parameters in my qlik-visual component.
Yes it is, but you need the id from the measure or dimension. Specify that as qLibraryId. If you are refering to a measure, you also need to add qType:"measure", otherwise the api will assume it's a dimension.
