I was hoping the community could help where Linoma can not. That is one of the reasons for having a forum is it not?
As for "general usage of the product", do you mean this forum is just for the most popular parts of the product?
Building a custom task is part of the product. There are features like "install custom task" under the System menu in MFT and there is a product manual "Go Anywhere MFT Custom Task Guide", so although maybe less used its still part of the product and the use base can help. There are already posts on the beanInfo.xml which where useful.
I've actual fixed the issue now. Its a case of using a string array to return the results out of the custom task, then the variable can be used in a "forItem" loop.
ArrayList<String> resultSet = new ArrayList<String>();
I hope that helps anyone else who stumbles on this forum.
