Wicket migration 1.4 to 1.5.13 issue with WebmarkupContainer /WebComponent/ByteArrayResource
Hi Team -
How to change the below wicket version1.4 code to 1.5.13 , I tried
with WebComponent(String ,IModel<?> model), it doesn't work.
When I'm using the below code its placing the pdf content in the form
component but not in the WebmarkupContainer.
*getRequestCycle().scheduleRequestHandlerAfterCurrent(new
ResourceRequestHandler(byteArrayResource,null));*
Thanks for any help.
*xyzPage.java*
*------------------------------------------------------------------------------*
pdfPanel = new WebMarkupContainer("pdfPanel") {
public boolean isVisible() {
return irMode != IRMODE.EDIT;
}
};
pdfPanel.setOutputMarkupId(true);
pdfPanel.setMarkupId("pdfPanel");
pdfPanel.setOutputMarkupPlaceholderTag(true);
add(pdfPanel);
pdfPanel.add(new EmbeddedPDFComponent("pdfReport", null) {
/**
*
*/
private static final long serialVersionUID = 1L;
transient byte[] data = null;
public boolean isVisible() {
return irMode != IRMODE.EDIT;
}
@Override
public boolean showToolbar() {
return false;// irMode == IRMODE.PRINT;
}
public void onResourceRequested() {
DynamicWebResource pdfResource = new DynamicWebResource() {
/**
*
*/
private static final long serialVersionUID = 1L;
@Override
protected ResourceState getResourceState() {
// TODO Auto-generated method stub
return new ResourceState() {
@Override
public String getContentType() {
return "application/pdf";
}
@Override
public byte[] getData() {
if (data == null {
try {
data = generatePdfIr();
refreshPrint = false;
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
return data;
}
};
}
};
pdfResource.onResourceRequested();
}
}.setOutputMarkupId(true).setMarkupId("pdfReport"));
moduleForm.ClearBooleanFlags();
}
*EmbeddedPDFComponent.java:*
public class EmbeddedPDFComponent extends WebComponent implements
IResourceListener
{
private static final long serialVersionUID = 1L;
protected final DynamicWebResource resource;
/**
* Construcxt.
*
* @param componentID
* component componentID
* @param resource
* the resource
*/
public EmbeddedPDFComponent(String componentID, DynamicWebResource resource)
{
super(componentID);
this.resource = resource;
}
/**
* @see wicket.IResourceListener#onResourceRequested()
*/
public void onResourceRequested()
{
resource.onResourceRequested();
}
/**
* @see wicket.Component#onComponentTag(wicket.markup.ComponentTag)
*/
protected void onComponentTag(ComponentTag tag)
{
if (!"object".equalsIgnoreCase(tag.getName()))
{
findMarkupStream().throwMarkupException(
"Component "
+ getId() + " must be applied to a tag of type 'object' not "
+ tag.toUserDebugString());
}
if(showToolbar())
tag.put("data",
getResponse().encodeURL(urlFor(IResourceListener.INTERFACE))+"#toolbar=1&statusbar=0&messages=0&navpanes="
+ (showNavPane()?"1":"0"));
else
tag.put("data",
getResponse().encodeURL(urlFor(IResourceListener.INTERFACE))+"#toolbar=0&statusbar=0&messages=0&navpanes="

tag.put("type","application/pdf");
super.onComponentTag(tag);
}
public boolean showToolbar(){
return false;
}
public boolean showNavPane(){
return false;
}
}

What do you mean with "the parent menu are no longer available" ?
With "getRequestCycle().scheduleRequestHandlerAfterCurrent(new
ResourceRequestHandler(byteArrayResource, null));" you tell Wicket to
stream the byteArrayResource to the browser.
If you use "Content-Disposition: ATTACHEMENT" then the browser will show a
dialog asking the user whether to save the file or to open it with the
default software (e.g. Adobe Actobat).
If you use "Content-Disposition: INLINE" then the browser will try to show
the file by using a plugin, i.e. open the .pdf in the browser if possible.
In both cases the parent component should not be affected. Either the page
is at its old state (ATTACHMENT) or completely replaced (INLINE).

Hi,
To be able to help you I'll have to setup a project with 1.4 and try to
migrate it.
It is not clear in your mail what exactly is the problem. The code snippets
are rather long and it hard to guess.
Also the code snippets are hard to read. It would be better to use some
pastebin service with proper indents and maybe even code coloring.

/WebComponent/ByteArrayResource
To: users@wicket.apache.org
Hi Team -
How to change the below wicket version1.4 code to 1.5.13 , I tried
with WebComponent(String ,IModel<?> model), it doesn't work.
When I'm using the below code its placing the pdf content in the form
component but not in the WebmarkupContainer.
*getRequestCycle().scheduleRequestHandlerAfterCurrent(new
ResourceRequestHandler(byteArrayResource,null));*
Thanks for any help.
*xyzPage.java*
*------------------------------------------------------------------------------*
pdfPanel = new WebMarkupContainer("pdfPanel") {
public boolean isVisible() {
return irMode != IRMODE.EDIT;
}
};
pdfPanel.setOutputMarkupId(true);
pdfPanel.setMarkupId("pdfPanel");
pdfPanel.setOutputMarkupPlaceholderTag(true);
add(pdfPanel);
pdfPanel.add(new EmbeddedPDFComponent("pdfReport", null) {
/**
*
*/
private static final long serialVersionUID = 1L;
transient byte[] data = null;
public boolean isVisible() {
return irMode != IRMODE.EDIT;
}
@Override
public boolean showToolbar() {
return false;// irMode == IRMODE.PRINT;
}
public void onResourceRequested() {
DynamicWebResource pdfResource = new DynamicWebResource() {
/**
*
*/
private static final long serialVersionUID = 1L;
@Override
protected ResourceState getResourceState() {
// TODO Auto-generated method stub
return new ResourceState() {
@Override
public String getContentType() {
return "application/pdf";
}
@Override
public byte[] getData() {
if (data == null {
try {
data = generatePdfIr();
refreshPrint = false;
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
return data;
}
};
}
};
pdfResource.onResourceRequested();
}
}.setOutputMarkupId(true).setMarkupId("pdfReport"));
moduleForm.ClearBooleanFlags();
}
