how to pass process multiple process model in if condition...

Hi Kavya,

I'll need a bit more information. Do you mean that you want to call an expression rule from a series of process models and edit a date?

1. Is this intended to be dynamic and can be called from any process model in future?
2. What's the date?
3. Is the specific process model that decides if the date should be edited? Or some other piece of data?
4. How is the date to be edited?

What's the scenario and context?

here i have attached image FYI

this datefield belongs to multiple Work Flows of Process models..... 

I have to make editable datefield for one work flow(which contains multiple process models) 

for remaining Work flows remains same [read only date] 

Is this Admin Extension Date to be saved into a database?

yes

So the value will go into a CDT. Is it a user entered value or is it something like "Deadline date + 60 days" or "Today + 60 days"? What decides this date?

those all are not in my requirements as of now, just datefield need to be editable for some process models and non editable for some process models. bcz using same interface in multiple places 

hi kavyamutter,
but there is in general a deeper reason. Why should this field editable? why not? Whats the effect if I insert a date there?

I echo other commentors' feedback here so far in that it seems like you need a better foundation of requirements before really implementing something large-scale here (or else you risk doing a lot of setup that you need to re-do later when your requirements become better realized).

However, to provide a "simple" answer to your question: your interface can be given a new rule input, i.e. "isAdminExtDateEditable" (boolean).  In the process model node configuration where the interface is used, you would pass a literal value of "true" into that rule input for process models in which it should be editable, and "false" where it should be treated as read-only.  You would then use the value of the rule input to determine the "readOnly" parameter for that field.

Mike has put into words the reason I was asking so many questions. There is no "that is not my requirement" when it comes to developing. The skill in coding isn't the literal coding, it's knowing what tool to implement in a particular scenario and what is at the heart of what you're trying to resolve.

Without contextual information and knowing the true purpose of a piece of functionality any solution is just guessing and what lies in the future is poor user experience and refactoring.

We also aren't trying not to be helpful. You have asked quite a high level question and as there isn't specific details we're left guessing which solution of at least 10 different options we should tell you. If you asked a much more targeted question we'd be happy to answer specifically.
