User Story (Required on creation):
As a user, I can set an expression to formHandlerClass attribute to resolve a class instance (and for example use beans) in Start Forms and User Task Forms.
Example
User Task XML Config:
<bpmn:startEvent id="StartEvent_1" camunda:formHandlerClass="${mySpecialFormDataHandler}">
handlers:
@Component("mySpecialFormDataHandler") @Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE) public class MyHandler extends DefaultStartFormHandler { @Override public void submitFormVariables(VariableMap properties, VariableScope variableScope) { //Some validation goes here VALIDATION GOES HERE super.submitFormVariables(properties, variableScope); } }
@Component("mySpecialUserTaskFormDataHandler") @Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE) public class MyUtHandler extends DefaultTaskFormHandler { @Override public void submitFormVariables(VariableMap properties, VariableScope variableScope) { //Some data validation logic goes here super.submitFormVariables(properties, variableScope); } }
This can be used to implement data structure validation on the variables being sent: Such as "XYZ variable names can or cannot be created or modified", "The JSON object must match a specific Schema, etc.
Functional Requirements (Required before implementation):
- `formHandlerClass` attributes supports expressions for Start Forms and User Task Forms.
