issue with model1 & model2 hasone

I apreciate if someone can help, i made a diagram to explain it better
I select one row form a table(model2 "ator") based on condition of joomla-logged user

return array("ator.nif" =>$login);

after that I join with model1 "paper" all the rows that have same parameter " egrupo" of selected row['ator']['egrupo']

all is working fine , but the issue is that as suggested in http://www.chronoengine.com/faqs/72-ccv5/5218-adding-1-more-belongsto-model-to-our-connection.htmlwe can call some row parameters from model2
but i couldn't get the value of row['ator']['ecoord'], what i need is a php row function that depending of value of this parameter shows or not the field

paper.rates:return ($row['ator']['ecoord'] >0? $cell : "0");

Hi teldrive,

You are doing this in the listing ? if yes then are you sure that the "ator" fields are loaded correctly ? please try to use one of its fields in the "columns list" box to make sure that the model is loaded before trying to use the field info into the functions box.

hi Max, thanks by reply
I have tried but failed, may be due to model2's "condition" returns only one raw , (it's fine because only one record has this ator.nif)

return array("ator.nif" =>$login);

it results interesting, after "join condition" applied, that paper.egrupo shows 4 raws but ator.egrupo not

Please try to clear the "Fields" box because the "ator" table fields are not loaded in the query!

Its advised not to use the fields box before everything is working fine, its only useful when your table has a lot of fields, but in your case its not needed and CC will load all fields by default.
