Petals Studio

In the dialog box, on the page where you select the services to consume (cf EIP_router_1.png), if you edit a consumed service an try to enter a running condition (XPath or operation), there is the following error message "The "operation" namespace is invalid" displayed at the top of the dialog box and it is impossible to click on OK (cf EIP_router_2.png).

I think I induced you in error this morning (sorry).
In fact, this error comes from the third tab. The one that defines the invocation properties.
I should switch the two tabs, so that there is no ambiguity. You would have seen it before.

Then if you click on Cancel and try again to edit the same consumed service to enter a running condition, it is only possible the XPath expression or the operation but not the both (although you clicked on Cancel previously) (cf EIP_router_3.png & cf EIP_router_4.png).

This is normal. You cannot mix both kind of conditions.
The first condition kind defines the kind of all the other conditions within this EIP.
I should also add a message the first time to explain it.

On another hand, the height of the consumed project edition dialog box must be greater because when you open this dialog box and you clicked on the tab Routing Condition, it is necessary to increase the height to see all the content of the tab (cf EIP_router_5.png).

You are right.
I will update the title of this bug. For me, most of your troubles come from a non-intuitive UI.

Still in progress.
I think this wizard will be replaced by another approach in the version 1.2 of the studio.

Commit # 1865
+ The UI was updated in the EIP wizard (new tab order, remember dialog size and position, etc.).
+ Router EIP: allow to switch between operation and Xpath conditions.
+ List of consumable end-points is now ordered by service name.
+ Fix the edition of generated CDK widgets.

The wizard was updated and should be less difficult to use than before.
However, a new approach will have to be found for the next version of the studio.
