hello everyone I'm trying to build a webpage with two oneMenu the second one depending on the second one. My XHTML file is below as well as my bean.
when I try to create a new "structureAttache" I have the following problem
TemplateStructureAttache.xhtml @40,139 value="#{structureBean.structureAttache.intituleStructure}": Target Unreachable, 'structureAttache' returned null
and when I use the method initStruc to create a new structureAttache then I call it in the listener of my first ajax, I succeed to create a structureAttache but when I do it for the second time, it seems like the value already exit in the DB and it refuses please help me to solve this issue
