[jbosstools-issues] [JBoss JIRA] Created: (JBIDE-4512) "var cannot be resolved" does not recognize single value
"var cannot be resolved" does not recognize single value
--------------------------------------------------------
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
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 <a
href=https://jira.jboss.org/jira/browse/JBIDE-4048>JBIDE-4048</a>).
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 <a href=https://jira.jboss.org/jira/browse/JBIDE-3336>JBIDE-3336</a>)
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).
