issues in getting IMarkupWriter object
Hi all,
i am using tapestry4.1.5
i have problem in getting IMarkupWriter object in my component.when i say
cycle.getResponseBuilder().getWriter(getClientId(),
ResponseBuilder.ELEMENT_TYPE) its throwing null pointer exception.when i
debugged the sourcecode its failing in getWriter(String id,String id) method
which is in DojoAjaxResponseBuilder class.When it renders the component the
getWriter(String id,String id) method is returning IMarkupWriter object.But
in rewinding phase its throwing null pointer exception.The exception i am
getting is as follows..
Unable to present exception page:

Hi,
Did you fix your problem? We am getting the same NPE. In our case this
happens when we use the back button back to a page that triggers an async
submit.
I filed a bug under https://issues.apache.org/jira/browse/TAPESTRY-2714
