How to read Hidden Value in Tapestry Page class ?
Hi,
I open a new window ('child window') from my Tapestry application (parent
page)...and put an object into session.
When the user Closes the 'child' window, i change in the 'Parent page' a
Hidden Value of a property to TRUE and then do a refresh to that page.
Now I want to be able to READ the Value of Hidden Property during the
PageBeginRender but Somehow the new Value is not getting updated. I do the
following
I am injecting this in java class
@InjectObject("service:tapestry.globals.HttpServletRequest")
public abstract HttpServletRequest getRequest();
.... String isPreview= getRequest().getParameter("isPreviewMode");
HTML file :
<form jwcid="@Form" >
<input jwcid="@Hidden" value="ognl:isPreviewMode" id="isPreviewMode" />
</form>
But I confirmed that the HTML has the new value because I do alert the value
on body unload and it shows the new value.
What am I doing wrong here ? Any idea anyone ?
Thanks for the help in advance..
- Sunil M

Thanks Shing.... I was simply reloading the page. I changed the javascript
to do a Form Submit and works like a charm..
Thanks once again..

Posted by Shing Hing Man <ma...@yahoo.com>.
I presumed when you said 'refresh' the parent page,
you mean you have submitted the form on the parent
page.
When the form is submitted, the pageBeginRender is
called twice.
1) PageBeginRender method is called in rewinding mode.
None of the submitted values from the form are
available yet(including the hidden value).
2) Form rewinded.
3) PageBeginRender mthod is called again to render the
page(in rendering mode). The hidden value is
available. now.
If you want to do something as soon as the hidden
value is available, you could try using the listener
parameter of the Hidden component.
