Isomorphic,

Are there any restrictions on the number of datasources which may be included for use in an application ?

We've had some issues where adding a new datasource to our project results in the failure to successfully open a datasource.

Removing a few from the HTML then allows the application to happily proceed.

Could this be a memory issue ? If so, what is the resolve ? Are there limits on the software ? I don't recall the actual count now but it would be less than 130 (since we are now at 122 and removed less than 8). Is this a known issue ? Is it resolved in a more recent release of 3.1 ? Going to 4.x is not currently an option. Am I just making a basic mistake ? Do you need more information before making a response ?

Concerned as we will soon get to that point once again so need to know if we need to take a different approach to handling large number of datasources ( if this is considered large ).

Richard.
