Description

A <switch> element contains a sequence of one or more <case> elements and an optional <default> element.

When present, the <default> element must be the last element in the <switch>. Correspondingly, in the Business Process Designer, the <default> element must be the right-most option in the <switch> part of the diagram.

When a <switch> element is executed, it evaluates each <case> condition in turn. These conditions are logical expressions in the scripting language of the containing <process> element. If any expression evaluates to the integer value 1 (true), then the contents of the corresponding <case> element are executed; otherwise the expression for the next <case> element is evaluated.

If no <case> condition is true, the contents of the <default> element are executed.

Activities within a <default> element can be any BPL activity listed above, including <assign> elements as in the example below:

<switch name='Approved?'>
  <case name='No PrimeRate' condition='context.PrimeRate=""'>
    <assign name='Not Approved' property="response.IsApproved" value="0"/>
  </case>
  <case name='No Credit' condition='context.CreditRating=""'>
    <assign name='Not Approved' property="response.IsApproved" value="0"/>
  </case>
  <default name='Approved' >
    <assign name='Approved' property="response.IsApproved" value="1"/>
    <assign name='InterestRate'
            property="response.InterestRate"
            value="context.PrimeRate+10+(99*(1-(context.CreditRating/100)))">
      <annotation>
        <![CDATA[Copy InterestRate into response object.]]>
      </annotation>
    </assign>
  </default>
</switch>
