Conditional validation in Orbeon Forms

Question

I have an orbeon form which contains 5 fields with save and Send buttons.

On save, only two fields are mandatory and on send all 5 fields are mandatory.

How to write validation for this scenario.

Update:

I added hidden field with Control Name : ValidationMode and my process looks like:

<property as="xs:string" name="oxf.fr.detail.process.save.*.*">
     xf:setvalue(
        ref   = "bind(ValidationMode-bind)",
        value = "'save'"
    )
    then xf:dispatch(
        name     = "xforms-recalculate",
        targetid = "fr-form-model"
    )
    then validate-all
    then save-final
</property>

Still the conditional validation is not working. Please help

You can use the save-draft button to allow saving without validating. See this documentation. But save-draft will entirely skip checking validation before saving.

Update

If you want to validate (with "Required" or constraint formulas) depending on the button pressed, I can think of the following way.

Whether a field is required can be expressed by an XPath expression. Somehow that XPath expression would have to depend on the current button pressed, and validation would have to be reapplied at that time. So you could do the following:

Add a hidden form field, say validation-mode, which will contain a value identifying whether the user has pressed one button or the other, say save or send or blank.
Make your validations depend on that field (using $validation-mode).
Write a new process associated with each of the "Save" or "Send" buttons which:
- Sets the value of the hidden field, say to save or send.
- Forces recalculation/revalidation. There is no built-in action for this yet, but you can do so with the xf:dispatch(name = "xforms-recalculate", targetid = "fr-form-model").
- Then continues with the process as usual.

So the processes would look like:

<property as="xs:string" name="oxf.fr.detail.process.save.*.*">
    xf:setvalue(
        ref   = "bind('validation-mode-bind')",
        value = "'save'"
    )
    then xf:dispatch(
        name     = "xforms-recalculate",
        targetid = "fr-form-model"
    )
    then validate-all
    then expand-all
    then save-final
</property>

<property as="xs:string" name="oxf.fr.detail.process.send.*.*">
    xf:setvalue(
        ref   = "bind('validation-mode-bind')",
        value = "'send'"
    )
    then xf:dispatch(
        name     = "xforms-recalculate",
        targetid = "fr-form-model"
    )
    then validate-all
    then expand-all
    then send(
        uri     = "http://posttestserver.com/post.php",
        method  = "post",
        content = "xml",
        replace = "all"
    )
</property>
