ALC-DSC-000-000 on a "Set Value" activity

[Joël_Royer]

I have in my form some hidden  fields I want to set in the process, before user assignement. For this, I use the Set Value activity.

But when I tried to set a field of my form with a value, I got this error:

Internal error.: ALC-DSC-000-000: com.adobe.idp.dsc.DSCRuntimeException: Internal error.

It seems to be an xml parsing problem. Maybe a mistake in the xml schema of my form? For the moment, I don't see any mistake in my schema.

Any idea?

[chetanm_oct]

From the exception it looks like you are passing a byte array instead of a string

Cannot coerce object: [B@10e410e4 of type: [B to type: interface org.w3c.dom.Document

My "Set Value" activity tried to set a text-field value with the field userId from a User object.

Do you mean that the field userId in User object is a bytearray field?

[Jasmin_Charbonn]

Can you post your xPath expression?

Jasmin

[Joël_Royer]

Here is a screenshort of the part of my workflow:

In the mappings of the "Set Value" activity, I have one line with those properties:

Location: /process_data/bonusValidationForm/object/data/xdp/datasets/data/BonusValidationForm/buManagerID

Expression: /process_data/currentUser/object/@userId

Where:

• bonusValidationForm is a process variable of my workflow that point my xdp form
• buManagerID is the textfield I want to set
• currentUser is a process variable (type User) that was well setted by the task Find BU Manager

[Jasmin_Charbonn]

Your setValue looks fine.

Are you sure it's failing on that step? Have you used Record and Playback to double check?

Jasmin

[Joël_Royer]

Yes, the process is stalled on this activity, with this exception.

I tried to set my textfield with a hard-coded value ("10" as expression) and it works! Then it seems to be a casting problem between my textfield which is a string and the field userId which seems to be a bytearray. Is anybody know how to cast a bytearray to a string with a xpath expression?

Please type cast expression into an string.

For example string(/process_data/currentUser/object/@userId)

Thanks
