Hello,
I got a paginator from the ClickClick project and works just fine.
My only problem is that sometimes, i'd like to pass some parameters to the
next page and I don't always want to do this in the URL. Since the
paginator is using a link - all the parameters will be passed in the URL.
I updated the paginator in such a way that it is using a submitLink and
submits a form with hidden parameters. Unfortunately, something is off and
I can only get from page one to page two - i can't get to the last page and
next only goes one page up. It must be something silly but I can't see it.
Or maybe I'm using a wrong approach?
I'm going to post the code that doesn't work and then the code that uses the
link and works.
Any help will be appreciated.
A problematic code:
protected void renderLast(HtmlStringBuffer buffer) {
buffer.elementStart("li");
String pageValue = String.valueOf(getPageTotal() - 1);
if (getCurrentPage() < getPageTotal() - 1) {
buffer.appendAttribute("class", "last");
buffer.closeTag();
SubmitLink submitLink = getSubmitLink();
submitLink.setLabel(getLastLabelMessage());
submitLink.setParameter(Table.PAGE, pageValue);
submitLink.setTitle(getLastTitleMessage());
Form form = new Form("nextForm");
form.add(submitLink);
Field field = new HiddenField(Table.PAGE,String.class);
field.setValue(pageValue);
form.add(field);
for (Enumeration<String> e = httpRequest.getParameterNames();
e.hasMoreElements();) {
String param = e.nextElement();
String value = httpRequest.getParameter(param);
if(!param.equals("column") &&
!param.equals("page") &&
!param.equals("actionLink"))
{
Field f = form.getField(param);
if (f != null)
f.setValue(value);
else
{
f = new
HiddenField(param,String.class);
f.setValue(value);
form.add(f);
}
}
}
form.render(buffer);
} else {
buffer.appendAttribute("class", "last-off");
buffer.closeTag();
buffer.append("<table><tr><td><tr><td>");
buffer.append(getLastLabelMessage());
buffer.append("</td></tr></td></tr></table>");
}
buffer.elementEnd("li");
}
Below is the method that only uses links and works fine:
protected void renderLastOrig(HtmlStringBuffer buffer) {
buffer.elementStart("li");
String pageValue = String.valueOf(getPageTotal() - 1);
if (getCurrentPage() < getPageTotal() - 1) {
buffer.appendAttribute("class", "last");
buffer.closeTag();
buffer.append("<table><tr><td><tr><td>");
AbstractLink controlLink = getControlLink();
controlLink.setLabel(getLastLabelMessage());
controlLink.setParameter(Table.PAGE, pageValue);
controlLink.setTitle(getLastTitleMessage());
StringBuffer params = new StringBuffer();
for (Enumeration<String> e = httpRequest.getParameterNames();
e.hasMoreElements();)
{
String param = e.nextElement();
if(!param.equals("column") &&
!param.equals("page") &&
!param.equals("actionLink"))
{
controlLink.setParameter(param,
httpRequest.getParameter(param));
}
}
controlLink.render(buffer);
} else {
buffer.appendAttribute("class", "last-off");
buffer.closeTag();
buffer.append("<table><tr><td><tr><td>");
buffer.append(getLastLabelMessage());
}
buffer.append("</td></tr></td></tr></table>");
buffer.elementEnd("li");
}
