Is it normal behavior for the <s:fileUpload> to call the setter for byte[]
twice? I'm mean first it calls it for the byte[] with the file data and then it
calls it with a null. I used seam 1.2.1.GA on jboss 4.0.5.GA. The project was
build with seam-gen.
package app.beans.entity;
|
| import javax.ejb.Remove;
| import javax.ejb.Stateful;

| import org.jboss.seam.annotations.Destroy;
| import org.jboss.seam.annotations.Logger;
| import org.jboss.seam.annotations.Name;
| import org.jboss.seam.annotations.Scope;
| import org.jboss.seam.core.FacesMessages;
| import org.jboss.seam.log.Log;
|
| @Stateful
| @Name("uploadFile")
| @Scope(ScopeType.EVENT)
| public class UploadFile implements java.io.Serializable, UploadFileI {
| private static final long serialVersionUID = 940956938635067807L;
| @Logger
| private Log log;
| private byte[] byteArray;
| private String fileName;
| private String size;
| private static int count = 0;
| public UploadFile() {

| public String getFileName() {
| return fileName;
| }
| public void setFileName(String fileName) {
| this.fileName = fileName;
| FacesMessages.instance().add("i'm here set File name =
"+this.fileName);
| }
| public byte[] getByteArray() {
| return byteArray;
| }
| public void setByteArray(byte[] byteArray) {
| count++;
| //SUGESTED FIX
| // if (byteArray == null) {
| // FacesMessages.instance().add("i'm here
setByteArray("+byteArray+");null count:"+count);
| // return;
| // }
| this.byteArray = byteArray;
| FacesMessages.instance().add("i'm here
setByteArray("+byteArray+"); count:"+count);
| }
| public String getSize() {return size;}
| public void setSize(String size) {
| this.size = size;
| FacesMessages.instance().add("i'm here set File size =
"+this.size);
| }
|
| @Remove @Destroy
| public void destroy() {
| }
| public void reset() {
| count=0;
| }
| }
the interface
| package app.beans.entity;
|
| import org.jboss.annotation.ejb.Local;
|
| @Local
| public interface UploadFileI {
| public String getFileName();
| public void setFileName(String fileName);
| public byte[] getByteArray();
| public void setByteArray(byte[] byteArray);
| public String getSize();
| public void setSize(String size);
| public void destroy();
| public void reset();
| }
|
the form
| <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";>
| <html xmlns="http://www.w3.org/1999/xhtml";

| <head>

| </head>
| <body>
| <h:messages styleClass="message"/>
| <h:form id="form" enctype="multipart/form-data">
|
| <h:panelGrid columns="2">
| <h:outputText value="file name" />
| <h:outputText value="#{uploadFile.fileName}" />
|
| <h:outputText value="file size" />
| <h:outputText value="#{uploadFile.size}" />
|
|
| <h:outputText value="file size" />
| <h:inputTextarea value="#{uploadFile.byteArray}" />
|
| <s:fileUpload data="#{uploadFile.byteArray}"
fileName="#{uploadFile.fileName}" fileSize="#{uploadFile.size}"/>

| </h:panelGrid>
| </h:form>
| </body>
| </html>
|
what to expect
| * i'm here setByteArray([EMAIL PROTECTED]); count:1
| * i'm here set File name = IMG_3332.jpg
| * i'm here set File size = 1647973
| * i'm here setByteArray(null); count:2
|
I was get NPE when trying to access the 'byteArray' an couldn't figure out why.
Since the fileName and size where set ok.
Is this a bug ?
