[jboss-jira] [JBoss JIRA] Commented: (JBAS-6242) invoke() for "listFormattedSubPoolStatistics" ManagedOperation on datasources and connection factory ManagedComponents returns a MetaValue with the wrong MetaType

[Charles Crouch (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBAS-6242?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12455447#action_12455447 ] 

Charles Crouch commented on JBAS-6242:
--------------------------------------

We need to know at compile time the full signature of the operation (return value and arguments) so that we can render the UI correctly. The UI is rendered from the operation definition not the runtime results.

At runtime when we invoke the operation we can try and be clever about converting the type we actually get back to the type we expect. In fact this is what it looks like we are doing anyway since the listFormattedSubPoolStatistics operation is correctly returning a result which we display as a string in the console.

Given the operation appears to be working now, I think we can drop the priority on this and revisit at a later date.

>From todays discussion one solution to this general problem would be to define managed operations in terms of specific arguments and results. So you would have one managed operation that specified the String based statistics formatter and another that passed in the JBossSubPoolStatistics, and each would have a different return type.

> This is another case of the data not matching the metadata.
> operation.getReturnType() returns a MutableCompositeMetaType w/ typeName java.lang.Object. However, invoke() is returning a SimpleMetaType.STRING (with value e.g. "Sub Pool Statistics: \nSub Pool Count: 0\n------------------------------------------------------\n").
