The new SystemContext system data dictionary
gives letters in Correspondence Management access to information
in the current system context. The system context comprises information
about the currently-logged in user and active configuration parameters.
In particular, the current implementation of the SystemContext DD
contains the following DDEs: agentID
agentName
agentFolder
agentSignatureImage
The new agentSignatureImage DDE is a computed
DDE representing the agent’s signature image. The expression for
this computed DDE uses a new custom function exposed by the Expression
Manager building block. This custom function takes agentID and agentFolder as
input parameters and fetches the image content based on these parameters.
The value of agentFolder is taken from the CMUserRoot configuration parameter
for the Asset Composer configuration service. You can change the value
of the CMUserRoot configuration parameter using
the Felix configuration UI. By default this configuration parameter
points to /content/cmUserRoot in the CRX repository.
You can override the default custom function to define your own
logic for fetching the user signature image.
Manage agent imagesThe administrator uploads all agent signature images at
the location to which the CMUserRoot parameter
points. Image names must be the same as the userid of
the corresponding agents. No file extensions are needed for the
image file names.
Correspondence workflowThe form designer adds an image field to the appropriate
form layouts. These image fields will hold the user signature image.
At the time of creating a letter, the subject matter expert
(SME) selects a form layout that contains an image field to display
the user signature image.
In the Data Editing view, the subject matter expert selects
an image field for the signature image. She follows these steps:
When the letter is rendered, the agent can see her signature
in the image field.
