hi,
this happens because you access the Person object before
it is instantiated. the easiest thing is to add a if before your
input to check whether the object is null
in tapestry 4.1 theres is the InjectStateFlag annotation
that returns true if your ASO is instantiated
or you can instantiate your Person object during the init phase
of your page by accessing it once
g,

help injecting tate objects
hello I've the following problem:
hivemodule.xml
.............
<contribution configuration-id="tapestry.state.ApplicationObjects">
<state-object name="wizardPerson" scope="session">
<create-instance class="org.jfly.demo.edittable.vo.Person" />
</state-object>
</contribution>
........
page template:
.......
<inject property="person" type="state" object="wizardPerson"/>
.......
html template:
.....
<input jwcid="@Insert" value="ognl:person.name"/>
.....
The exception thrown when I access the page is:
log
ognl.OgnlException: person [java.lang.IllegalStateException: Cannot create
a
session after the response has been committed]
at ognl.OgnlRuntime.getMethodValue(OgnlRuntime.java:1046)
at ognl.ObjectPropertyAccessor.getPossibleProperty(
ObjectPropertyAccessor.java:60)
at ognl.ObjectPropertyAccessor.getProperty(
ObjectPropertyAccessor.java:134)

page:
Unable to parse OGNL expression 'person.name': Error compiling expression

object [EMAIL PROTECTED] with expression node person.name getter

How can I solve this ?
