The Design view displays the results of both real-time and explicit validation in callout windows on the diagram and the error stripe.
In the illustration,
A red cross next to an element on the diagram means that the element has not passed validation and the output contains errors.
A yellow triangle with an exclamation mark means that the element has not passed validation and the output contains warnings.
A red cross in the Design view means there are both errors and warnings.
If you click the cross or the triangle, a callout window lists errors and warnings.
The callout window displays messages related to validation in accordance with the criteria listed above. Messages related to real-time validation are constantly updated.
In the Design view, the error stripe displays the validation results. The error stripe is a strip to the right of the scroll bar that contains red marks if some elements have not passed validation. The error stripe represents the entire diagram, not just the portion that is currently displayed. This stripe helps users to immediately detect any errors in the BPEL process without having to scroll through the entire diagram. Click a red mark to jump to the element that causes problems. If no errors are detected, the small square in the error stripe is green.
