Forget this post, obviously this NPE is not a Trinidad problem but of our
own changed backend .. ;)

Trinidad 1.2.13: another upgrade problem: Now UIXCollection unserializable
Hi,
Have to restate the result of the update from 1.2.9 to 1.2.13 ;(
Now on another page which used to work we get a new problem which,
however, has to do with basically the same saveState serialization
problem.
We now get an NPE when trying to do a search on a treeTable component.
This search triggers the NPE because Trinidad attempts to serialize
the applied treeTable see the following stack trace.
Any ideas? Is it possible to get back to a less strict serialization
mechanism ??
Does the row key set now always need to be set i.e. non-empty?
The treeTable is simply used like this:
<tr:treeTable initiallyExpanded="true"
inlineStyle="table-layout:fixed; overflow:auto;
margin: 0px 10px 10px 10px;"
width="780"
rowsByDepth="#{TC1004.rowsByDepth}"
var="node"
value="#{TC1004.tc1004TreeModel}">
...
</tr:treeTable>
Thanks in advance..

BTW it works now. The problem was simply due to our platform approach of
throwing an exception when a Trinidad ERROR occurs,
in this case the serializable error one can see in the log.. ;)

Wolfgang.

Antwort: Re: Trinidad 1.2.13: another upgrade problem: UINodePropertyKey

Hi,
Thanks again for the info.
I will try to find out more by setting CHECK_STATE_SERIALIZATION which in
this case, as far as I understood, should
be the right approach, should not it?
The problem seems to be with the SortableModel object and the applied
UINodePropertyKey.
Best wishes
Wolfgang

Re: Trinidad 1.2.13: another upgrade problem: UINodePropertyKey

hi,
https://issues.apache.org/jira/browse/TRINIDAD-1245
introduced some improvements in the direction of not sticking illegal
stuff into the session.
(during that we also introduced those error messages:
* <!-- UNSERIALIZABLE_PROPERTY_VALUE_NO_CONTAINER -->
<resource key="UNSERIALIZABLE_PROPERTY_VALUE_NO_CONTAINER"
dnt="false">Nicht serialisierbarer Wert: {0} für Schlüssel:
{1}</resource>
* <!-- COMPONENT_CHILDREN_SAVED_STATE_FAILED -->
<resource key="COMPONENT_CHILDREN_SAVED_STATE_FAILED"
dnt="false">Status für untergeordnete Komponenten von Komponente: {0}
konnte nicht gespeichert werden</resource>
)
can you double check for the parameters ?
