Let suppose I create a new custom field (is_addtoapplane) of type bool, if it is true then, at the time of project creartion, i am hitting a webservice and all the data of the project is saved on that webservice,but at the time of project creation, i am checking its value from params.
But when I want to create a issue and want to add this issue to my another project applane, then I need the data of custom field(is_addtoapplane) for that project in which issue is being created, so that check can be performed.
