The file is successfuly deleted, but the problem is when reloading the
page (Manually).
In my listener I redirected:
throw new PageRedirectException(cycle.getPage("Images"));
where Images is my current page.
In this case, no error is displayed, but when reloading, the next
image in list is also deleted.
I found a way to prevent this, but I don't think is a very good way:
I substitute StaleLink.page and StaleLink.html. At the StateLink.html I wrote:
<script type="text/javascript">window.location.href=document.referrer;</script>
It works, but only if I use externalLinks. But when I submit a new
image, it clears my external refference. So I don't think this is a
solution.
I read at the Reference, about "Form" Component:
Parameter: stateful
If true (the default), then the component requires an active (i.e.,
non-new) HttpSession when triggered. Failing that, it throws a
StaleLinkException. If false, then no check is necessary. Generally,
forms are stateful, but it is possible to put a stateless form onto
the Home page of an application.
I thought this could help me, but it didn't.
I believe there is a simple solution to my problem. Here is some of my code:
public void DeleteImg(IRequestCycle cycle){
boolean exists = (new
File(uploadPath+getSelectedName())).exists();
if(exists){
boolean success = (new
File(uploadPath+getSelectedName())).delete();
if (!success) {
// Error Handling
}
}
}
At my page:
<property-specification name="currImg" type="java.io.File" />
<property-specification name="selectedName"
type="java.lang.String" initial-value="''"/>
...
<component id="feImage" type="Foreach">
<binding name="source" expression="fileList"/>
<binding name="value" expression="currImg" />
<binding name="index" expression="index"/>
<static-binding name="element" value="tr"/>
</component>
<component id="iFileName" type="Insert">
<binding name="value" expression="currImg.name"/>
</component>
<context-asset name="delete" path="images/error.png"/>
<component id="sbDel" type="ImageSubmit">
<binding name="image" expression="assets.delete" />
<binding name="selected" expression="selectedName"/>
<binding name="tag" expression="currImg.name"/>
<binding name="listener" expression="listeners.DeleteImg"/>
</component>
Thanks.
