pageBeginRender is called during both rewind and render. I don't know
what test you did to make you think it only gets called during rewind.
public void pageBeginRender(PageEvent event) {
if (!event.getRequestCycle().isRewinding()) {
// put render cycle init code here
}
}
I've got code similar to this all over my codebase and I know that it
works exactly as expected. In fact, my actual pageBeginRender
implementation in my base page implementation looks like the
following:
@InitialValue("ognl:false")
public abstract boolean isOnceInitialized();
public abstract void setOnceInitialized(boolean val);
public final void pageBeginRender(PageEvent event) {
initPage(event);
if (!isOnceInitialized()) {
initOnlyOnce(event);
setOnceInitialized(true);
}
if (getRequestCycle().isRewinding()) {
initForRewind(event);
} else {
initForRender(event);
}
}
// gets called before both rewind and render cycles
public void initPage(PageEvent event) {
}
// guaranteed to be called only once, whether there is a rewind
// cycle or not
public void initOnlyOnce(PageEvent event) {
}
// gets called before rewind cycle
public void initForRewind(PageEvent event) {
}
// gets called before render cycle
public void initForRender(PageEvent event) {
}

Thank you, but I've seen from code that beginPageRender is called only
during rewind
so I added a property to the page and did the following:
/**
* Reset the grid content if the page is accessed without form
submission
* (refresh or new access), then performs normal renderPage operations.
*/
public void renderPage(ResponseBuilder builder, IRequestCycle cycle) {
if (!getFormRewound().booleanValue()) {
setEditItemCollection(new ArrayList());
}
setFormRewound(Boolean.FALSE);
super.renderPage(builder, cycle);
}
/**
* Called by the framework during rewind. It informs the page the it
* has been rewinded when the renderPage method will be called
*/
public void beginPageRender() {
setFormRewound(Boolean.TRUE);
}
Is there any better way to do this ?
ciao,
