    Placeholders can be used in process definition through the process variable 'petalsPlaceholders', for example in a JUEL expression:

    ${empty execution.variableInstances.petalsPlaceholders.getValue().placeholderValue1 ? "default-value-1" : execution.variableInstances.petalsPlaceholders.getValue().placeholderValue1}

    One a process instance is started, the placeholder values are not updated when reloading them. But a process instance started after the placeholder reloading uses the palceholder values updated.

To be able to use up-to-date value for placeholders, we must introduce a new custom JUEL function. This JUEL function will return the current value of a placeholder:

${petals:getPlaceholder('placeholder-name')}

or

${petals:getPlaceholderWithDefault('placeholder-name', 'default-value')}
