| | | - begin-conversation in Seam2 prevents data load | - begin-conversation in Seam2 prevents data load 2007-07-12 - By damianharvey
Back
Morning,
I have an issue with jboss-seam-2 (See http://eam-2.ora-code.com).0.0.BETA1.
I have an all-on-one CRUD page where selecting an item in the table reloads the
current page and populates the create/edit form in another div. If the page.xml
has <begin-conversation join="true"/> then the form will not be populated (ie.
the form field values are not set). If I remove the <begin..>, then it works
(the form field values are populated with the data from the selected table row).
A conversation isn't required for my example page, however I have some more
complex pages where one is.
The same behaviour was not present in Seam 1.2.1GA. I have tried this with a
sample app Seam-Gen'd using both Seam2.0.0 and also with Seam1.2.1.
My example form PersonList.xhtml:
<!DOCTYPE composition PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

-transitional.dtd">

| </s:decorate>
|
| <div style="clear:both">

|

|
| <rich:panel>
| <f:facet name="header">Person search results</f:facet>
| <div class="results" id="personList">
| <rich:dataTable id="personList"
| var="person"
| value="#{personList.resultList}"
| rendered="#{not empty personList.resultList}">
| <h:column>
| <f:facet name="header">
| personId
| </f:facet>
| #{person.personid}
| </h:column>
| <h:column>
| <f:facet name="header">
| firstName
| </f:facet>
| #{person.firstname}
| </h:column>
| <h:column>
| <f:facet name="header">
| lastName
| </f:facet>
| #{person.lastname}
| </h:column>
| <h:column>
| <f:facet name="header">action</f:facet>
| <s:link view="/PersonList.xhtml"
| value="Select"
| id="person">
| <f:param name="personPersonid"
| value="#{person.personid}"/>
| </s:link>
| </h:column>
| </rich:dataTable>
|
| </div>
| </rich:panel>
|
| </ui:define>
|
| </ui:composition>
|
My PersonList.page.xml:
| <?xml version="1.0" encoding="UTF-8 (See http://UTF-8.ora-code.com)"?>
| <page xmlns="http://jboss.com/products/seam/pages"
| xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
| xsi:schemaLocation="http://jboss.com/products/seam/pages http://jboss
.com/products/seam/pages-2 (See http://ges-2.ora-code.com).0.xsd">
|
| <begin-conversation join="true"/> <!-- the line that causes my hair-loss
-->
| <param name="personPersonid" value="#{personHome.personPersonid}"/>
|
| </page>
|
Has the way that conversations are treated changed between 1.2.1 and 2.0.0?
Nothing in the changelog.txt rings any bells. I have looked at the debug output
but can't spot anything that would cause this behaviour.
I can upload this sample app (both versions) if anyone would like to see it.
Thanks,
Damian.
