Constraints are Getting Set During Server Start

anujs86

Hi,

Do any one know when does alfresco sets up constraints values ?
I think its at server start.

What if I want to add dynamic constraint fetching values from database?
If I have many drop down constraints in my application, it will take lot of time for server start.

Do any one knows solution to it?

Hi Anuj,

You can use custom constrain in that case.
Where you need to create a javaclass which will populate the drop down from the db.

I went through it Mit.
Its generating its own component for drop downs.
Can't I use existing component and get the results?
I have more than one drop down and according to content type I need to get values.
I am getting handle in getAllowedValues() which gets called during run time but what I am not getting is for which property its getting called.

mitpatoliya

the property with which you have associated your custom constrain.

anujs86

Yes. But I have 4 properties defined in custom constraint class. So how come I know for which property getAllowedValues() get called?
According to property I need to fetch data from db.

mitpatoliya

then you require for different constrains classes and associated each of them sepratly.
I mean its quite logical any custom constrain will give certain set of values only.
So, better create 4 diff constrains.

Thanks Mit.
Actually I did not want to do that, but now probably have to go that way only

mitpatoliya

that is also the best practice. 😎
