Luca Gioppo commented on JBIDE-4512:
------------------------------------
the problem persist on 3.1 dev and eclipse 3.5
The seam generated entityes have lots of "cannot be resolved" it happens on
"one to many" relations it seems.
It does not recognize the var within the columns tag
<rich:dataTable value="#{tecnologiaUiHome.LTecnologiaUiServers}"
var="_lTecnologiaUiServer"
rendered="#{not empty tecnologiaUiHome.LTecnologiaUiServers}"
rowClasses="rvgRowOne,rvgRowTwo"
id="LTecnologiaUiServersTable">
<rich:column
sortBy="#{_lTecnologiaUiServer.id.idTecnologiaUi}">
<f:facet name="header">Id tecnologia ui</f:facet>
<h:outputText
value="#{_lTecnologiaUiServer.id.idTecnologiaUi}"/>
</rich:column>
<rich:column sortBy="#{_lTecnologiaUiServer.id.idServer}">
<f:facet name="header">Id server</f:facet>
<h:outputText
value="#{_lTecnologiaUiServer.id.idServer}"/>
</rich:column>
<h:column>
<f:facet name="header">Action</f:facet>
<s:link id="selectlTecnologiaUiServer"
value="Select"
view="/LTecnologiaUiServer.xhtml">
<f:param name="lTecnologiaUiServerIdTecnologiaUi"
value="#{_lTecnologiaUiServer.id.idTecnologiaUi}"/>
<f:param name="lTecnologiaUiServerIdServer"
value="#{_lTecnologiaUiServer.id.idServer}"/>
<f:param name="lTecnologiaUiServerFrom"
value="TecnologiaUi"/>
</s:link>
</h:column>
</rich:dataTable>
Seam Validator raises "property cannot be resolved"
warnings when single value is used instead of List
------------------------------------------------------------------------------------------------------
Key: JBIDE-4512
URL: https://jira.jboss.org/jira/browse/JBIDE-4512
Project: Tools (JBoss Tools)
Issue Type: Bug
Components: jsp/jsf/xml source editing
Affects Versions: 3.0.0.GA
Environment: JBossTools-ALL-win32-3.0.1.GA-R200905070146-H18, Seam 2.1.1.GA
Reporter: Julien Kronegg
Assignee: Alexey Kazakov
Fix For: 3.1.0.M2
Attachments: edit.xhtml.ftl, EntityHome.java.ftl, MyBean.java,
singleValuedVarCannotBeResolved.png, view.xhtml.ftl
Jboss Tools does not recognize correctly the "var" property in list iterators
(e.g. rich:dataTable, h:dataTable) if the "value" property is a single value
(but works if the "value" property is a List.
This problem occurs for XHTML pages generated by seam-gen where the value is
"#{myEntityHome.instance.singleValue}" (see
https://jira.jboss.org/jira/browse/JBIDE-4048).
Effects:
1. add a lot of warnings "variableName cannot be resolved" that should be
there
2. makes "Seam Validator" task to be very slow when there is a lot of pages
(because the Seam Validator task is run on each XHTML file with at least one unresolved
EL, see https://jira.jboss.org/jira/browse/JBIDE-3336)
Expected:
As the rich:dataTable displays one row when the "value" property is a single
value and not a list, Jboss Tools is expected to recognize list AND single value.
How to reproduce:
EXECUTE: Create seam project.
EXECUTE: Create MyBean component (see attached java file)
EXECUTE: Open home.xhtml
EXECUTE: Add:
<h:dataTable var="myVar" value="#{myBean.values}">
<h:column><h:outputText
value="#{myVar.myProperty}"/></h:column>
</h:dataTable>
<h:dataTable var="myVar" value="#{myBean.singleValue}">
<h:column><h:outputText
value="#{myVar.myProperty}"/></h:column>
</h:dataTable>
<h:dataTable var="myVar"
value="#{myBean.singleValueAsList}">
<h:column><h:outputText
value="#{myVar.myProperty}"/></h:column>
</h:dataTable>
ASSERT: no warning "myVar cannot be resolved" appear
Workaround:
Use a "value" property as List and not as single value (maybe wrapping the
single value to a List should do the trick).
