Callfire IVR XML: trying to find out the length of the input..

[Natraj]

Hi all,

I'm working on Callfire's XML for the IVR:

I need to do some branching based on the length of the last input.

I've tried the following, and none have worked:
<if expr="${call.lastinput.length} &lt; 9" >
<if expr="${call.lastinput}.length &lt; 9" >
<if expr="length('${call.lastinput}') &lt; 9" >

The call just drops when it encounters this node.

Appreciate any tips in this regard.

thanks,
Natraj

Natraj,

You can't put the Java statement ".length" within the system variable. It goes after, like this:

<if expr="'${call.lastinput}'.length &lt; 9">

Note that I have single quotes around the variable ('${call.lastinput}'), as it is being evaluated as a string. This is necessary for this node to work.
