turing off calculations

Hi Guys,

Can someone tell me how I can make my bind calculations conditional
depending on whether or not I'm in readonly mode? (I have an instance
that says readonly true/false)

I tried using the "relevant" tag on the bind, but this just hid the
field entirely if readonly was set to true.

Many thanks,

Would the if() function do the trick for you?

@calculate="if (readonly = 'false') then perform calculation else do not perform calculation"

Colin,

What about something like:

calculate="if (instance('my-instance')/is-readonly = 'true')
            then .
            else 1+2+3"

thanks.

Is it possible to hide/show buttons using a similar method based upon the same rule?

Hi Colin,

You can hide/show triggers by binding them to a node and have a
<xforms:bind> for that node. If you have relevant="..." which
evaluates to false, then the button will not show. If you have a
readonly="..." which evaluate to true, then the button will be grayed
out.

In most cases, there are no existing nodes which you can conveniently
bind your triggers to, but you can easily create an instance just for
this:

<xforms:instance id="ui">
    <ui>
        <save-trigger/>
        <cancel-trigger/>
    </ui>
</xforms:instance>

<xforms:trigger ref="instance('ui')/save-trigger">
    ...
</xforms:trigger>

somthing like:

<xforms:trigger ref=".[condition]">
    ...

Where "condition" evaluates to boolean true() or false(). If true(). the
control will be relevant, if false(), it will be non-relevant and
therefore hidden.
