Re: [sca-bpel] Issue 11 - BPEL variable initialization and SCA properties

[Alex Yiu <alex.yiu@oracle.com>]

Hi all,

Just want to archive our text properly ... :-)
Here is the current proposal being discussed on the conf call on this Issue 11:
(not passed yet)(formulated in Michael Rowley's 2 messages)
--------------------------------------

Michael Rowley: If the variable has an initialization from-spec then that becomes the default value for the variable in cases where the SCA component does not provide a value for that property.  If a value is provided for the property, the initialization from-spec is not evaluated.

 

If the from-spec is a literal value, where it has the following form:

   <from><literal>literal value</literal></from>

then the literal value will be represented as the default value in the component type for the process.  Any other kind of initialization from-spec will not be represented in the component type.  However, even though the other kinds of initialization from-spec are not represented in the component type, they would still be computed and used as the default value for the property when the component does not provide a value for that property.
Michael Rowley: If a BPEL variable that is used as a property has an initialization from-spec then mustSupply="false" must be specified on the component type property declaration.

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


Thanks!
