Expression Editor

The Expression editor Show picture allows you to type and edit expressions in your eSpace.

The areas and elements available in the Expression editor are presented below.

Edit area

The top window pane. In this area, you edit your expression by:

Typing the expression directly.
Right-click on the typed expression and select the "Complete Word" or use CRTL + Space to complete your expressions. Service Studio provides you a drop-down list with the possible elements, based on what you typed so far. Therefore you don't have to actually type the complete expression.

In addition, if you want to use a compound element, such as a Widget, Site Property or a Session Variable, select respectively, the widget name, Site or Session followed by "." and Service Studio automatically displays a drop-down list with the runtime properties or the variables.

In this situation, the element you selected in the drop-down list is automatically highlighted in the Scope tree and you can check its definition and help text.

Using the operator buttons and the elements in the Scope tree, such as Variables or Built-in Functions, for example.

If you want to check the definition or the help text of any element, place the cursor over the element, right-click and then select the Synchronize Scope Tree option or simply press CTRL + K.

Scope tree

Description area

This area contains a description of the currently selected element, which is the value of the Description property of the element or, in the case of functions, a description automatically gathered by Service Studio that includes:

the data type of the function output, that is, in the case of the user functions, the data type of the output parameter,
the description of the function. Built-in functions' descriptions are always provided by Service Studio. User functions present the text in the Description property of the user-defined action,
the list of the input parameters, their Is Mandatory and Data Type properties as well as their Description property if not empty.

Verify button

The Verify button checks whether the expression is valid. It checks both the syntax and the expression evaluation. In function calls, it may rearrange the arguments' so they'll be ordered as in the function definition.
