Binding model attributes disables UI elements

Question

Hi ,
  I have created a model. and did bind its attributes to the UI elements. RFC is working fine.
But in the runtime all UI elements are disabled bydefault when i bind these to the model attributes but to the same UI element if i bind it to the local attribute its working fine...
I have tried reimpor and recreating model , and also changing the cardinality but not working...
Would not it be possible to bind UI elements to model attributes ?  By using model attributes how the UI elements can be enabled ?
Please help me out...

hi,
this occurs becoz u would have bound the i/p element to a model attibute whose value is null.
to solve dis,
1)create a context attribute in ur view
2)bind  the i/p elements to that context attr
3)while executing the rfc , get the value of this context attr and set it to the model attr.
for example if u have a model attr 'name_mo ' which u have to bind to the i/p field element
create a context attr -
name_vn
bind name_vn to the i/p field element
while executind ur rfc,
Test_Input ip = new Test_Input();
ip.setName_mo(wdContext.currentContextElement().getName_vn());
Test_Input is the name of the model node that is bound from model to the view via comp.ctller
