Functions.throwError

Functions.throwError(key [, String[] args])

Description

• Ends execution and throws an error with the specified message via the Java API
• Supports Language Translation via Translation Workbench
• Translates the token and displays the translated message in the selected language

Element	Display Type	Description
key	string	A category name, followed by '.' and a message or label identifier (a "token"). Example: #categoryname.tokenname
String [] args	string	Optional Declares an array of Strings in Java (or Arguments) If arguments are passed, the call expects a token If no arguments are passed, the message alone is displayed

Syntax

<syntaxhighlight lang="java" enclose="div">

void = Functions.throwError(String key [, String[] args])

</syntaxhighlight>

If no arguments are needed (for example, for a label in the #custom category), use:

<syntaxhighlight lang="java" enclose="div">

Functions.throwError("#custom.label",null) </syntaxhighlight>

Return

• Returns the message configured on the key in the Translation Workbench
• If no key is configured in the translation workbench, then the passed key is returned

Example

This example checks a parameter passed to it to see if it is equal to "Acme". If it is, the code calls throwError to display an error message saying that the account cannot be "Acme".

<syntaxhighlight lang="java" enclose="div"> if(requestParams.get("name").equals("Acme")) { // message "Account cannot be Acme" will be shown to the user in the UI. Functions.throwError("Account cannot be Acme"); } else { // Normal business logic. } </syntaxhighlight> To include linebreaks in the message, specify <br>: Functions.throwError("Include <br> for <br> newline");
