Hi,
Our Firewall blocks the POST request from PrintTask.execute if the JSON is over a certain character length. This happens when a user adds too many graphics to a map. Currently the print task just fails. Instead, I'd like to be able to do one of the following:
- query the length of the Web_Map_as_JSON and not execute the task if it is too long (instead I'll warn the user).
- or, edit the json to strip out the offending graphics layer if it is too big.
I found a couple of posts that mention the _getPrintDefinition(). This returns an object, and I could use it to find how many graphics are in each graphics layer, but I would really prefer converting the entire object to the same Json used by the task. Is that possible? If I could convert it, then I could determine how many characters the Json is, and achieve 1. above.
Even better would be if I could somehow edit the Json before the print task sends it and achieve 2. above. However, from what I've found, this doesn't seem possible.
Any suggestions? Thanks, S. Roberts
