Determining cause of xforms-value-changed
Locked
 
|
Dear all,
While developing my application, this question keeps popping up again and again, so I thought it might be wise to pose it here. In several cases, we have a field which may either be a) entered by the user or b) found using a search dialog. In addition to the value binding, there is an attribute associated with the field to indicate whether the value was picked from a list, or manually entered. This value is used to quickly show entered/"custom" values in a different color/style than those known by the system, rather than having to check each value against the database to see which are which. The problem is that it seems both <xforms:setvalue> and entering text manually trigger the same event: xforms-value-changed. How can I tell the different between the two so that the appropriate action may be taken in each case? Many thanks in advance! -Gino

Gino,
Since you know the values users can choose from, can you on xforms-value-changed compare if the entered value is one of those, and set the attribute in consequence? Doesn't this sound the right way to do it anyway? Say the dialog shows A, B, C. If the user types X, you want to mark it as a "custom" value. But if they type A, you'll want to mark it as a "provided" value, just as if users selected A from the dialog, right?

Good point. I was trying to avoid the extra requests to
validate the value, but I suppose it’s small compared to the total number of
AJAX requested going back and forth. I will consider doing this in our next iteration.

Alessandro, I forgot to mention that there are too many possible values to
load into the model; they are fetched/searching using separate submissions. Best, Gino

Hi again! I’ve been trying to do this in my XBL component without
success. On xforms-value-changed, I trigger a submission which checks if the
value is valid (and returns the correctly formatted one). The problem is that my
xforms-submit-done handler only works when it is in the xforms <model>.
From there, I cannot figure out how to get at the component’s single-node
binding attributes. So, in the model I have something like: <xforms:submission id="validate-field-submission"
method="post" action="{$params/url}?scheme={$params/scheme}&q={$params/q}" replace="instance" instance="validation-result-instance"> </xforms:submission> <xforms:action ev:event="xforms-submit-done"
ev:observer="validate-field-submission"> … I’ve tried using <group>, and various combinations of
xbl:attr and xbl:scope to no avail. How get at the component’s @ref, etc. from
here? Thanks again! -Gino From: Alessandro Vernet

Gino,
Are you saying that if you place the <xforms:action ev:event="xforms-submit-done" ev:observer="validate-field-submission"> in the "view" of your XBL component (inside <xbl:template>), it never gets called? Are you sure that this xforms:action is in the inner scope (xxbl:scope="inner")?

Gino,
There is absolutely no problem; take it easy, and I'll see you around here in a few weeks.
