Description

I'm not sure if this error is specific to ognl. If it is I can refile there.

I have a page:

.java

public abstract class TestPage extends BasePage {

public abstract String getSelectedName();
public abstract void setSelectedName(String s);
public String[] getNames() {
return new String[]

{"name1", "name2", "name3" }

;
}
}

.html

<table jwcid="table@contrib:Table"
source="ognl:names"
columns="selected" />
<span jwcid="selectedColumnValue@Block">
<span jwcid="@If" condition="ognl:components.table.tableRow.equals(selectedName)">
Selected
</span>
<span jwcid="@Else">
Not selected
</span>
</span>

When I try to access this page, I get the following error:

ERROR org.apache.tapestry.services.impl.HiveMindExpressionCompiler - Error generating OGNL getter for expression components.table.tableRow.equals(selectedName) with root $TestPage_42@3c1[TestPage] and body:

{ return ($w) ((($TestPage_42)$2).getComponents().get("table")).getTableRow().equals(((org.apache.tapestry.contrib.table.components.Table)(($TestPage_42)$2).getSelectedName()));}
