Strings longer than 127 characters

Question

Hello,
is it now possible to add a String from a POJO with more than 127 characters?
Thanks

When you design a Crystal Reports report in Crystal Reports for Eclipse, where you drop in a POJO class for a datasource, you'll see that all String columns are given the default length of 127.
When you inject a Collection of POJO class instances into the report using the setDataSource(java.util.Collection, ...), you'll see that any String with length greater than 127 is truncated. 
How do you avoid this?
In the JRC for XI R2 - you could re-compile the pojoSample.jar file after modifying the default value, or you could specify a longer length using the POJOResultSetFactory.setMemberColumnDisplaySize(...) method.
The POJOResultSetFactory method for Crystal Report for Eclipse has been renamed and incorporated into rasapp.jar.  The source code for the POJO factory classes are no longer provided - thus, the XI Release 2 solutions do not work.
So what you will need to do for CR for Eclipse, is you must manually create the ResultSet by invoking the com.crystaldecisions.sdk.occa.report.application.internal.POJOResultSetHelper class directly - POJOResultSetHelper is for CR4E what POJOResultSetFactory was for XI Release 2.
Here's a code snippet:
    // SimplePojo.class is my POJO class, getName is a String property for the class,
    // and arrayList is the Collection of POJO class instances.
    POJOResultSetHelper pojoHelper = new POJOResultSetHelper(SimplePojo.class);
    pojoHelper.setMemberColumnDisplaySize("getName", 256);
    java.sql.ResultSet rs = pojoHelper.createResultSet(arrayList);
    reportClientDocument.getDatabaseController().setDataSource(rs, "SimplePojo", "SimplePojo");
