Configuring the application to use multiple data sources

Sorry I was so vague, I hate it when people do that.  I also didn't realize this created a forum post in the adobe forums, so for context I am stating that the datasource attribute on a persistent component cannot be dynamic. If you try to set the datasource attribute using a variable or method it will fail with the error:

So for example, in your Application.cfc you set:

this.datasource = "SOME_DSN";

application.myDSN = "SOME_OTHER_DSN";

this.ormEnabled = "true";

....

Then, in Art.cfc (using the example in the docs):

<cfcomponent persistent="true" datasource="#application.myDSN#" table="Art">

  ...

</cfcomponent>

This will result in said error.  If I set the datasource to static text it works:

<cfcomponent persistent="true" datasource="SOME_OTHER_DSN" table="Art">

  ...

</cfcomponent>
