    Strange datasource limitation

    So my webapp seems to stop working when the number of "cities" available to a user is greater than 24.

    Each city is its own database, and when the user logs in, they are given a dropdown of cities. Whenever a user has access to 25 or more cities, the app stops working. Is there a limitation in number of datasources  that can be loaded?



    1. SNAPSHOT_v10.1d_2014-09-07/PowerEdition Deployment (built 2014-09-07)
    2. All browsers

    Below is the only error I could fine, an RPC transport error.


    Code:
    {

    Hi wriley,

    see the FAQ, it could be related to the length of your URL (6997 chars).

      Oh, and when using v10.1d, you should really be using a recent nightly.

        Yet it works just fine when the length is 6408? According to Microsoft, the limit is 2038. This makes no sense. I do not see anthing in the FAQ regarding URL length. At any rate, thanks for the response.

          It is right in the linked chapter:
          If you are loading a very large number of DataSources, the URL can be too long and be rejected
          before it even reaches SmartGWT Server code. In this case, split the URL into two <script> tags

            You seem to be very knowledgeable on the subject. Could you maybe explain what splitting it into two <script> tags means?

              Code:
              http://login.emnet.net/CSOnet_CITIES/CSOnet/sc/DataSourceLoader?loadParents=true&dataSource=firstPartOfTheList
http://login.emnet.net/CSOnet_CITIES/CSOnet/sc/DataSourceLoader?loadParents=true&dataSource=secondPartOfTheList
              I never did this, though. I think that I read that you'll have to watch that the DS in each call are independent of each other w.r.t. to includeFrom etc.

                Normally, the DS are loaded in ther main html file, see builtInDS. There it is a <script> tag.
