Seam Gen template error?

[damianharvey]

(This is a bit pedantic but thought it belonged here anyway)

If you have a ManyToOne association that goes more than one level deep eg. A PERSON associated with a COMPANY associated with a COUNTRY then the SeamGen view template has a small error on line 83 of the view.xhtml.ftl

It is currently:

${'#'}{${parentName}.${parentProperty.name}.${parentPojo.identifierProperty.name}}

but should be:

${'#'}{${parentName}.${parentProperty.name}.${parentParentPojo.identifierProperty.name}}

It results in an error in the generated View page as the property is set as such:

<h:column>
<f:facet name="header">countryCode countryId</f:facet>
#{company.countryCode.companyId} <!--is this the problem -->
</h:column>

Cheers,

Damian.

You're not alone. I'm seeing the same error too when running against Oracle or MySQL

Ideas anyone?

[pmuir]

Put it in JIRA :)

[damianharvey]

I had the same issue but reverting to the templates from CVS and re-applying my changes fixed it. I assumed that there was a difference in the versions there somehow.

[saeediqbal1]

i just used eclipses built in cvs rep. to download jboss-seam folder from the "head" section in the repository. is that the one with new template files? or was it the version section?

[gavin.king]

This was already fixed in CVS.

[saeediqbal1]

i concur, this seems to be fixed now in the cvs build i downloaded.
