Preview Results

You can preview the results for a mashup or for any active block in a mashup. Simply click Preview on any block to see results for that block. Preview is not available on blocks for inactive mashable information sources or mashups.

It is a good practice to preview each block once you have set or changed properties or inputs. This also makes it easier to work with block properties.

Wires displays the results in the Tree view, which shows the structure of the result. You can also use the Grid view to just see data.

Some mashables and mashups return a large volume of results. Wires displays only the first 50 results. If you wish to see more results, your Presto administrator can change this setting. Be aware that large numbers of results can cause your browser to hang and stop responding.
