Hi, How you did that? I have the same problem, I have Framework Seam 2.0.2 but when I use seam-generate-entities it generate *Home.java with this wrong code: @Override | public boolean isIdDefined() { | if (Strings.isEmpty(getAccionsId().getIdDoc())) | return false; | if (Strings.isEmpty(getAccionsId().getIdTipus())) | return false; | if (Strings.isEmpty(getAccionsId().getIdUsuari())) | return false; | if (Strings.isEmpty(getAccionsId().getData())) | return false; | return true; | } In isEmpty method I have that error: The method isEmpty(String) in the type Strings is not applicable for the arguments (BigDecimal) How can I resolve it? Thanks very much. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4126524#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
