Expression Task


The "Expression Task" is used to set variables and call functions using our extensive expression engine. Each action is evaluated in the order they appear in the grid.



  Action - The action this step in the expression task will perform. There are 5 actions that can be performed.

o   Set Variable - This action will set the variable to the value entered in the "Value/Expression" column

o   Set Variable From Expression - This action will set the variable to the result of the value returned from the expression in the "Value/Expression" column

o   Set Variable and Replace Placeholders - This action will set the variable to the value entered in the "Value/Expression" column as well as replace any variable place holders in the text.

o   Replace Placeholders - This action will replace any placeholders that are part of the variable selected in the "Variable" column.

o   Call Function - This action will simply execute the expression set in the "Value/Expression" column.

 Variable - If the action requires you to select a variable, a drop down with all user defined variables will appear

 Value/Expression - Depending on the action, this will contain either a static value or an expression that will be executed at runtime.

 Validate All - Clicking this button will validate all the expression set in the "Value/Expression" column.

 Test Expression - Click this button will execute the selected expression using temporary values.
