[JBoss Seam] - help on s:fileUpload
by kingcu
Seam version 1.2.1.
I am always getting NULL value for the upload file. I tried using both InputStream and byte[]; I also tried putting the upload file property in a SLSB and a class that extends EntityHome, but neither worked. Anyway here is my code:
| <h:form enctype="multipart/form-data">
| <rich:togglePanel id="importFeeds" switchType="ajax" stateOrder="closed, import">
| <f:facet name="closed">
| <h:panelGrid columns="1">
| <rich:toggleControl for="importFeeds" value="Import Feeds »" />
| </h:panelGrid>
| </f:facet>
| <f:facet name="import">
| <h:panelGrid columns="1">
| <s:fileUpload data="#{widgetHome.feedDefFile}" />
| <s:button id="importFeed" value="Import..." action="#{widgetHome.importFeeds}"/>
| <rich:toggleControl for="importFeeds" value="« Close Import" />
| </h:panelGrid>
| </f:facet>
| </rich:togglePanel>
| </h:form>
|
| @Name("widgetHome")
| public class WidgetHome extends EntityHome<Widget> {
|
| .... // other methods
|
|
| @Logger
| private Log log;
|
| // No matter whether it's byte[] or InputStream, it's always null
| private byte[] feedDefFile;
| //private InputStream feedDefFile;
|
| public void importFeeds() {
| // I get an NPE exception on this, because feedDefFile is always null
| log.info("feedDefFile.length = " + feedDefFile.length);
| }
|
| }
