Subject: RE: [wsbpel] repeatUntil description issue
The <repeatUntil> constructs allows you to indicate the repeated performance of a specified iterative activity. The iterative activity will continue to be performed so long as after it executes the given Boolean <repeatUntil> condition holds true.
to Proposed Description:
The <doWhile> construct allows you to indicate the repeated performance of a specified iterative activity. The iterative activity is performed at least once. Following that the iterative activity will continue to be performed so long as the given Boolean <doWhile> condition holds true.

<scope> activity1 <while> <condition>bool-expr</condition> activity1 </while> </scope>The intent was to permit executing at least once and repeat as long as the condition holds true.

Hi Vinky,
I think the idea was to create a loop that executes at least once with a test after execution of the loop. As opposed to <while> which tests before the loop is executed and thereby the loop code may not execute at all. Is that still the semantics?

Subject: [wsbpel] repeatUntil description issue
As we discussed during the Nov 2nd conf. call. I would like to request opening the following new issue:
In 6.2 the description of <repeatUntil> is incorrect. It is opposite of the traditional meaning of a REPEAT UNTIL construct. The expected meaning is for the iterator to repeat *until* the boolean condition is met(becomes true). But the description says otherwise.
------------------------------------------------------------------------
Current description:The <repeatUntil> constructs allows you to indicate the repeated performance of a specified iterative activity. The iterative activity will continue to be performed so long as after it executes the given Boolean <repeatUntil> condition holds true.
Proposed Description:
The <repeatUntil> construct allows you to indicate the repeated performance of a specified iterative activity. The iterative activity will continue to be performed until the given Boolean <repeatUntil> condition becomes true.
