Siarhei Dudzin commented on JBIDE-1322:
---------------------------------------

Well yes, if you test with maven (for example) you do have a different classpath (because of dependencies in test scope). Usually, when I work with maven I already have that alternative (including test dependencies) classpath, at least this is what I get when generating project using maven-eclipse-plugin. It works with  with older wtp versions (hot deployment via wtp I mean - didn't have a chance to test seam since it ejb-3 wont work with older WTP). However they are just 2 bugfixes away from having a release with wtp-2 support, and those are:

http://jira.codehaus.org/browse/MECLIPSE-333 

and 

http://jira.codehaus.org/browse/MECLIPSE-264 

which is very interesting (from testing prospective) because it's easier to adapt ant to the 'default' eclipse wtp layout than do the same with maven.

Anyway, I actually meant somewhat 'smart' behavior of the wizard which would (hypothetically) do one of the following:

* Give a warning message but still create the form (skip tests)
* Provide a checkbox asking whether creation of test should be part of creating the form (although I think it would be nice that IDE does 'motivate' a user to have tests)
* Ask for a source folder/project on where to put tests (since test project is not detected the user would need to deal with the alternative classpath himself anyway)
* (Almost sci-fi :) Scan dependency tree and/or facets and put generated stuff in corresponding projects: entities in projects with JPA facets, xhtml in projects with JSF facets, tests in plain utility projects which are above JPA/WEB/EAR projects in the dependency tree

> I have Seam 2.0 assigned to a project that was created not by seam-gen (a maven web wtp project). While trying to create a form I after filling parameters I am getting an error. The eclipse logs show the following:
