[jira] Created: (HIVEMIND-178) Allow Conditional Contributions based on symbols (from SymbolSources)

Allow Conditional Contributions based on symbols (from SymbolSources)
---------------------------------------------------------------------

         Key: HIVEMIND-178
         URL: http://issues.apache.org/jira/browse/HIVEMIND-178
     Project: HiveMind
        Type: New Feature

  Components: framework  
    Reporter: Paul Field


Conditional Contributions are really handy during testing and I now have a number of features that I can turn on or off during development/testing. However, now there are several options, it's not particularly convenient to configure them through system properties; it would be nicer to have a single file containing all the flags.

I can create this single file and expose it as a SymbolSource, but conditional contributions cannot use the value of a symbol from a SymbolSource.

Please could you enhance the conditional contribution expressions to allow me to specify the name of a symbol from a SymbolSource.

[jira] Commented: (HIVEMIND-178) Allow Conditional Contributions based on symbols (from SymbolSources)

-----------------------------------------

Currently the contribution condition expressions as evaluated and applied at registry construction time. At this time the symbol sources have not been initialized and are hence not availiable. Thus your enhancement request would mean a rather big change.

As an alternative you might want to consider manually reading the file and setting corresponding system properties before constructing the registry. If this is satisfactory for your development/testing purposes we would probably close this issue for now.

-------------------------------------

We're developing web applications so setting system properties is not a particularly nice thing to do when you may be co-existing with other web applications (and it may be forbidden by the security manager).

However, the feature is a "nice to have" and we can live without it if it's a big change to HiveMind. Does it make sense to lower the priority and leave it open in case anyone wants to vote for it?
