RE: [wsrp-wsia] [change request #142] Remove performInteraction() ?

[Thomas Schaeck <SCHAECK@de.ibm.com>]

Although I really like the performInteraction operation since it is a nice
optimization, if we don't need it anymore to support the JSR we should
remove it from WSRP 1.0 nevertheless for the following reasons:

- It adds complexity - one additional operation
   -> adding to the complience test suite
   -> adding effort to compliance test execution
   -> adding effort to interop test execution
   -> adding complexity to consumer and producer implementations
   -> increasing the risk of non-interoperability of implementations from
different vendors

I think it is better to have a simple V 1.0 spec for which we can create
interoperable implementations without too many complexities and testing
effort than to have more bells and whistles rasing complexity and moving
out the date where we can achieve cross vendor interoperability.

Best regards,

Thomas

Portlet developers need not see perform(non-blocking)Interaction (as in JSR
168). One thing we can't do with render URLs / getMarkup is post form data.
Or have complex inputs generally, which seems a bit of a hole in our 2 op
model.

Andre

I vote for the "less is more" argument. One less complex concept to
understand and program to for portal developers!
