Implementation Example with Update Function¶

Initial display of input screen¶

// Delete because the session may remain when the browser is closed directly
SessionUtil.delete(ctx, "project");

// Acquisition process of the update target data is omitted

// Save the data to be updated in the session store
SessionUtil.put(ctx, "project", project);

// Convert Entity to Form
ProjectForm form = BeanUtil.createAndCopy(ProjectForm.class, project);

// Configure the update target data to the request scope
context.setRequestScopedVar("form", form);

Transition from the input screen to the confirmation screen¶

// Acquire input information from the request scope
ProjectForm form = context.getRequestScopedVar("form");

// Acquire update target data from the session store
Project project = SessionUtil.get(context, "project");

// Overwrite the input information with the update target data
BeanUtil.copy(form, project);

Return from the confirmation screen to the input screen¶

// Acquire the update target data from the session store
Project project = SessionUtil.get(ctx, "project");

// Convert Entity to Form
ProjectForm form = BeanUtil.createAndCopy(ProjectForm.class, project);

// Configure the update target data to the request scope
context.setRequestScopedVar("form", form);

Execute the update process¶

// Acquire the update target data from the session store
Project project = SessionUtil.get(ctx, "project");

// Update process is omitted

// Delete the update target data from the session store
SessionUtil.delete(ctx, "project");
