Hello,
In a service task, I’ve set a serializable POJO (with getters and setters) into the process variables and named it as request
.
execution.setVariable("request", releaseRequest);
In the next human task, I tried to use this object into a form created by Camunda Modeler using something like this ${request.releaseMethod}
, but I’m receiving a message “Form failure” in the task list.
I would like to show the already computed values that is on some of this object’s fields (as read only) and edit some others. Is there a way to do that ?
thanks
Hi,
I would input-output mappings on the user task:
- I’d use an input mapping to create a local variable for each attribute of the POJO that I’d like to view/edit.
- I’d change the form to show these variables rather than the POJO
- If we allow edits, I’d add an output mapping that updates the POJO variable based on the values.
Consider the following example process and form:
process.bpmn (3.8 KB)
form.form (524 Bytes)
The service task creates a variable of the following POJO:
package org.camunda.forum;
import java.io.Serializable;
public class Request implements Serializable {
private String requester;
private String request;
public String getRequester() {
return requester;
}
public void setRequester(String requester) {
this.requester = requester;
}
public String getRequest() {
return request;
}
public void setRequest(String request) {
this.request = request;
}
}
For the user task, I configured the input and output mappings:
