declaritive validation - validwhen

[Jan Groth]

hello,

i have the following constellation:

a group of three radiobuttons, each of them with a text-field next to it.

radio1 - text1
radio2 - text2
radio3 - text3

if a radio-button is clicked, i need to check that according text field is filled out and contains a valid float. (required, float)

even though "validwhen" looked pretty good on the first glimpse, i'm unable to find out the configuration for my problem.

here the generalized question again:
how can i trigger certain validations in dependence of a test?

thanks a lot for any help,
jan

Try this:

<field property="text1" depends="validwhen, float">
   <arg0 key="text1.label"/>
   <var>
      <var-name>test</var-name>
      <var-value>((radio1 == null) or (*this* != null))</var-value>
   </var>
</field>

This will only work if the float check accepts a blank value, which I'm not 100% sure it will. Give it a try anyway. Also, if radio1 is a boolean, substitute radio1 == false in the above code.

hi merril,

thanks for you answer...

this solution does not work... it will start the float validation if the radiobutton is not selected (radio1 == null). this might be tolerable for a float validation, but is not possible for a required validation.

the problem is that with validwhen i can only define a "exit point" before following validations:

( "validwhen, x, y" will not execute x and y if validwhen is not valid)

but i can't seem to write something like validatewhen, which would only execute x and y if validwhen computes to true.

looks like i need to code it by hand,
