Getting value of task parameters

With CONV you could get whole task from diagram:

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

or the parameter value from task:

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

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}}

With using CONV follow checks are performed:

specified ID of the state diagram, not the process
state diagram is not deleted
there is 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

Parameter name	Value
`__conveyor_set_param_return_type_error__`	software
`__conveyor_set_param_return_type_tag__`	set_param_wrong_convert_param
`__conveyor_set_param_return_description__`	Param:`{{param}}`, Value:`{{value}}`", Try convert to: `{{type}}`

There is no access to the specified state diagram

Parameter name	Value
`__conveyor_set_param_return_type_error__`	software
`__conveyor_set_param_return_type_tag__`	access_denied
`__conveyor_set_param_return_description__`	Param: `{{param}}`, User: `{{user_id}}`, Conv_id: `{{diag_id}}`

Specified process ID or state diagram deleted

Parameter name	Value
`__conveyor_set_param_return_type_error__`	software
`__conveyor_set_param_return_type_tag__`	access_refused
`__conveyor_set_param_return_description__`	Param: `{{param}}`, Conv_id: `{{diag_id}}` is not state type

When using CONV in other logics, only the name of the parameters is different, the values are the same.
