Creating a new XML node (allowed by schema) [message #672222]

Hi.

I need your help. I've received this [1] bpel message. Now I need to a
assign a new node, '<qualityRemark>value</qualityRemark>' to this
message. The schema [2, 3, 4] allows this node, but I don't know, how I
have to assign it correctly. If I do it like this [5] then i get a
selection failure.

How I have to assign this correctly?

Regards
Christian

Hi Christian,

In general, the structure of your "to" variable must be completely initialized with a literal. I'm not sure what the structure of your storeQualityRemarkRequest variable is, but I'm guessing it's more than just the single <sdl:sensorDataList> element.

Hi.

You're right! <sdl:sensorDataList> itself contains one <wg:waterGauge>
element and some <sd:sensorData> elements, which also contain some elements.

But how I have to initialize this, if i don't know the exact number of
<sd:sensorData> elements needed?

Regards!
Christian

I think you only need to include one complete element for lists (maxoccurs="unbounded"). For "choice" types you only need to include one element from the list of choices. Have you tried using the BPEL Designer's Assign Details property sheet tab to do the initialization for you?
