Validators

[Ilya Ermolov]

Hello! I have problem using validators in Woodstock components.

I have 2 drop down lists (webuijsf:dropDown) and thier content must be different.
How to solve this problem?

I implemented Validator interface, but validate method can't read information from other drop down.

You can either use the validateCompareTo component as found in the
Tomahawk sandbox release, which has now migrated to Tomahawk proper,
and is in the process of migrating to the Myfaces-commons-validators
project,

http://myfaces.apache.org/sandbox/validateCompareTo.html

or

You can use the code there to create your own -- either copy the
entire validator or just the parts you want, such as how to read
information from other input components.

I implemented Validator interface, but validate method can't read information from other drop down.

I invented simple solution. I binded my component with DropDown object in bean. Then created method dropDown_validate and used it in validatorExpresion property. In dropDown_validate I compare new value and selectedValue of second dropDown in binded object.
