Hi Pablo
I see your issue now.
First of all I didn't expect it to work at all, so I'm quite surprised.
The "criteria" is created on the SearchForm.pageBeginRender method, so
it's not being shared across requests.
The search field values aren't persisted in either client or session.
They neither are binded to anything so I would asume they should be
NULL every time we take the component out of the editors page.
It looks like my asumtions were wrong, the values ARE shared across
all the instances of the same component in the same request cycle.
I think this fixes it:
+++ modules/trails-hibernate/src/main/java/org/trails/component/search/SimpleSearchField.java Thu
Jul 03 12:28:55 CEST 2008
+ protected void cleanupAfterRender(IRequestCycle cycle)
+ {
+ setValue(null);
+ }
But I have to do a deeper test to confirm.
Please test the attached patch and then let me know how it goes.
Saludos.
Alejandro.

I see your issue now.
First of all I didn't expect it to work at all, so I'm quite surprised.
The "criteria" is created on the SearchForm.pageBeginRender method, so
it's not being shared across requests.
The search field values aren't persisted in either client or session.
They neither are binded to anything so I would asume they should be
NULL every time we take the component out of the editors page.
It looks like my asumtions were wrong, the values ARE shared across
all the instances of the same component in the same request cycle.
I think this fixes it:
+++ modules/trails-hibernate/src/main/java/org/trails/component/search/SimpleSearchField.java Thu
Jul 03 12:28:55 CEST 2008
+ protected void cleanupAfterRender(IRequestCycle cycle)
+ {
+ setValue(null);
+ }
But I have to do a deeper test to confirm.
Please test the attached patch and then let me know how it goes.
