I've imported the subprojects (wicket-rad-core, etc.) into Eclipse and changed all pom.xml files to use wicket-1.4-SNAPSHOT, as you have suggested. Indeed only a few things needed fixing. The attached patch contains the details and here is a description of these changes:
1. wicket-contrib-tinymce: Only changes in pom.xml were needed. First of all, I changed the version from 1.3.5 to 1.4-SNAPSHOT (see 2. below). Then the change to depend on wicket-1.4-SNAPSHOT, and finally and most importantly for me, I set the compiler level:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.5</source>
<target>1.5</target>
</configuration>
</plugin>
Without this, I got a strange error (unknown symbol Component.add(Component [])) due to Java 1.4's lack of generics.
2. wicket-rad-core: Updated the Wicket version in file wicketVersion. Changed a few occurences of setModel () to setDefaultModel() in FeedbackLabel.java. Updated the pom.xml to depend on wicket-1.4-SNAPSHOT in stead of 1.3 and to depend on wicket-contrib-tinymce 1.4-SNAPSHOT (see above). Notice that wicketstuff-dojo is still 1.3.0-beta.
I hope this helps in migrating to SVN trunk to 1.4!
Cheers,
Kaspar
