Thanks for you advice, it feels like im getting closer to what I want to
achieve.
Below I posted the Java/Tml for my Page.
(Initially I wanted this to be under components instead, but for clarity I
converted to a Page)
It seems to render stuff, but I still get Javascript Errors when I try to
use it.
---- ERROR----
Failure reading parameter 'value' of component Index:ajaxupload: Property
'file' (within property expression 'file.file', of
com.fante.pages.Index@1c8a395d) is null.
Communication with the server failed: Failure reading parameter 'value' of
component Index:ajaxupload: Property 'file' (within property expression
'file.file', of com.fante.pages.Index@1c8a395d) is null.
----------
I must admit, that I am not very proficient with Javascript.
Can you tell if Im on the right track here?
package com.fante.components;
public class Index {
@Persist
@Property
private List<FileHolder> files;
@Property
private FileHolder file;
@Persist
private int nrFiles;
public void beginRender() {
files = new ArrayList<FileHolder>();
}
@SuppressWarnings("rawtypes")
public ValueEncoder getEncoder() {
return new ValueEncoder<FileHolder>() {
public String toClient(FileHolder value) {
return value.getKey();
}
public FileHolder toValue(String keyAsString) {
Long key = new Long(keyAsString);
for (FileHolder holder : files) {
if (keyAsString.equalsIgnoreCase("" + holder.getKey()))
{
return holder;
}
}
throw new IllegalArgumentException("Received key \"" + key
+ "\" which has no counterpart in this collection: "
+ files);
}
};
}
FileHolder onAddRow() {
// Create a skeleton Person and add it to the displayed list with a
unique key
FileHolder newFileHolder = new FileHolder();
files.add(newFileHolder);
return newFileHolder;
}
public class FileHolder {
private List<UploadedFile> file;
private String key;
public FileHolder() {
file = new ArrayList<UploadedFile>();
key = "" + nrFiles;
nrFiles++;
}
public List<UploadedFile> getFile() {
return file;
}
public void setFile(List<UploadedFile> file) {
this.file = file;
}
public String getKey() {
return key;
}
public void setKey(String key) {
this.key = key;
}
}
}
In tml:
<t:form>
<t:submitnotifier>
${file.key} <input t:type='tawus/ajaxupload'
t:maxfiles="1" class="file" t:value="file.file" /> <br/>
</t:submitnotifier>
<p:addRow>
<br/>
<t:addrowlink>Add a row</t:addrowlink>
</p:addRow>
</t:form>
