> Key: AIRAVATA-298
> URL: https://issues.apache.org/jira/browse/AIRAVATA-298
> Project: Airavata
> Issue Type: New Feature
> Components: XBaya
> Reporter: Chathura Herath
> Assignee: Chathura Herath
> Priority: Minor
> Fix For: 0.4-INCUBATING
>
>
> Motivating usecase from LCCI is as follows.
> User plans to run a workflow with two components(A,B). Each of the components
> have input nodes attached to them. Also B follows A so output of A goes to an
> input of B.
> In this particular situation the user shall know the iput to component A, but
> does not know input to component B until such time component A finishes and
> user gets a chance to open and evaluate the output (we shall differ
> discussion on how we can make it easy to evealuate the outputs for later).
> Once the user evaluates the output of A he will know what to put into the
> input Node of B.
> Currently we ask all the inputs at the begining of the workflow launch thus
> workflow interpreter assumes that all the input nodes are filled. So we make
> the input boxes to FInish state at the very begining.
> Now we simply have to make some input boxes Gray(the ones for which we got
> the input) and others to be waiting/or some special state.
> For workflowinterpreter execution purposes this shall be as any other
> waiting(yellow) node. If at any point of time user click on config of such a
> input node and set the input value, we can move them to the finished state
> and workflow intepreter shall handle the rest of the execution.
> One optimization to keep in mind though is, during execution, if ALL the
> remaining waiting nodes in a workflow directly or transitively wait on such
> an input, workflow should goto a PAUSE mode until such time user enters a
> inputvalue.
