Getting value of task parameters

Getting values of task parameters

Using the CONV you can get the whole task from a State diagram:

{{conv[{{diag_id}}].ref[{{ref}}]}}

or a parameter value from a task:

{{conv[{{diag_id}}].ref[{{ref}}].param}}

Using this construction you can also get parameters values from a task in a process by its Alias:
{{conv[@alias-name].ref[{{ref}}]}}

From process or final node data couldn't be read.

Example:

//returns whole task with REF = menu from diagram with ID = 123456 (you need to specify parameter type Object)

{{conv[123456].ref[menu]}}

// returns parameter value amount from task with REF = qwerty diagram with ID = 123456

{{conv[123456].ref[qwerty].amount}}

// returns value from task with REF = {{ref}} and diagramm with ID = {{diag_id}}

{{conv[{{diag_id}}].ref[{{ref}}].ID_параметра}}

Using the CONV the following checks are performed:

• ID of a State diagram, not the process is specified
• state diagram is not deleted
• there is an access to the specified State diagram

Error types

Here describes the errors that occur when using CONV in the Set Parameter logic.

Invalid parameter type or parameter in the specified task is missing

There is no access to the specified state diagram

Specified process ID or state diagram deleted
