The second tab of the side panel corresponds to the rules parameter. In this tab, the input and output parameters are defined, which are the communication channel between rules and the processes that use them.
Parameters can be configured in any advanced rule except those of forms extension type.
Parameter Grid
The grid columns identify the properties of each parameter.
By placing the mouse over the grid, the following operations are enabled:
Allows modifying an existing parameter.

.
Data Type
It can be any type of Java object allowed in Deyel, either a primitive (integer) or an array.
The type wizard, while typing, gives the most common data type values to use.

Wizard to Create Parameters in JDBC Rules
Allows to invoke the wizard available for JDBC type rules.
This wizard allows to select the parameters defined in the SQL statement as input parameters and the columns resulting from the query execution as output parameters.
In this way, the probability of errors is minimized by not having to manually transcribe the names of columns and parameters.
For the wizard to return results, it is necessary to define the SQL statement to execute before invoking it.
Wizard to Add Operations in SOAP Rules
Allows to invoke the wizard available for SOAP type rules.
The wizard analyzes the adapter used and shows the operations available for such object, along with the input and output parameters for each one.
It allows to select the operation that is executed by default and its parameters, to transfer them to the rule interface. In this way, the probability of errors is minimized by not having to manually transcribe the names of operations and parameters.
