There is your basic
<g:FormPanel ui:field="formPanel" encoding="multipart/form-data"
method="POST">
<g:HTMLPanel>
<g:FileUpload name="data" ui:field="dataUpload" visible="false"
/><!-- not visible due to custom UI -->
<g:RadioButton stylePrimaryName="radio-check clearfix"
name="dataType" ui:field="textDataType" debugId="textDataType" text="Plain
text"/>
<g:RadioButton stylePrimaryName="radio-check clearfix"
name="dataType" ui:field="binaryDataType" debugId="binaryDataType"
text="Binary"/>
...
During setup/creation we programmatically assign the action via
formPanel.setAction.
In the end we do a formPanel.submit() when the user clicks on the upload
button.
On our servlet we have @MultipartConfig
Then our doPost:
Collection<Part> parts = request.getParts();
try {
checkXsrfToken(request);
try {
String dataType = request.getParameter("dataType");
Part data = request.getPart("data");
try (InputStream is = data.getInputStream()) {
Do your thing with the available data
}
} catch (... e) {
your error handling
}
} finally {
for (Part part : parts) {
try {
part.delete();
} catch (IOException e) {
logger.warn("Failed to delete part '{}' from server",
part.getName(), e);
}
}
}
