I've just started looking at seam-gen (with Seam 1.1.5 and Oracle XE) and it
fails when running the generate-entites task. It manages to build all the
entity beans, but breaks half way through building the xxxList.xhtml pages (it
does output about 10 files of an expected 40).
The error message is:
| ...

The part it's compaining about is in the for loop:
| <#foreach property in pojo.allPropertiesIterator>
| <#if !c2h.isCollection(property) && !c2h.isManyToOne(property)>
| <#if property.value.typeName == "string"><#-- IT BREAKS ON THIS LINE -->
| <tr class="prop">
| <td class="name">${property.name}</td>
| <td class="value">
| <h:inputText id="${property.name}"
|
value="${'#'}{${listName}.${componentName}.${property.name}}"/>
| </td>
| </tr>
| </#if>
| </#if>
| </#foreach>
|
I've tried changing the breaking line to the following, but freemarker
complains about my syntax.
| <#if (property.value.typeName)?? && property.value.typeName == "string">
|
Any ideas on why its throwing an exception or how to fix it would be greatly
recieved.
Thanks in advance, Pete
