Examples with FormData org.camunda.bpm.engine.form.FormData used on opensource projects

Example 1 with FormData

use of org.camunda.bpm.engine.form.FormData in project camunda-bpm-platform by camunda.

the class TaskResourceImpl method getForm.

@Override
public FormDto getForm() {
    FormService formService = engine.getFormService();
    Task task = getTaskById(taskId);
    FormData formData;
    try {
        formData = formService.getTaskFormData(taskId);
    } catch (AuthorizationException e) {
        throw e;
    } catch (ProcessEngineException e) {
        throw new RestException(Status.BAD_REQUEST, e, "Cannot get form for task " + taskId);
    }
    FormDto dto = FormDto.fromFormData(formData);
    if (dto.getKey() == null || dto.getKey().isEmpty()) {

            dto.setKey("embedded:engine://engine/:engine/task/" + taskId + "/rendered-form");
        }
    }
    // to get the application context path it is necessary to
    // execute it without authentication (tries to fetch the
    // process definition), because:
    // - user 'demo' has READ permission on a specific task resource
    // - user 'demo' does not have a READ permission on the corresponding
    // process definition
    // -> running the following lines with authorization would lead
    // to an AuthorizationException because the user 'demo' does not
    // have READ permission on the corresponding process definition
    IdentityService identityService = engine.getIdentityService();
    Authentication currentAuthentication = identityService.getCurrentAuthentication();
    try {
        identityService.clearAuthentication();
        String processDefinitionId = task.getProcessDefinitionId();
        String caseDefinitionId = task.getCaseDefinitionId();
        if (processDefinitionId != null) {
            dto.setContextPath(ApplicationContextPathUtil.getApplicationPathByProcessDefinitionId(engine, processDefinitionId));
        } else if (caseDefinitionId != null) {
            dto.setContextPath(ApplicationContextPathUtil.getApplicationPathByCaseDefinitionId(engine, caseDefinitionId));
        }
    } finally {
        identityService.setAuthentication(currentAuthentication);
