newbe question reg. orbeon xforms engine

Hi,

I am experimenting a bit with using orbeon xforms, and am wondering whether the slow response I am experiencing with my forms is in order.

For example, I have a simple trigger that causes a simple javascript to be executed.

<xf:trigger>

<xf:label>click me</xf:label>

<xxforms:script ev:event="DOMActivate">

alert("hello");

</xxforms:script>

</xf:trigger>

When I click the button, a "loading..." image is appearaing on the page and after about 2-3 seconds it disappears and the javascript alert/message is appearing. I looks like the click is triggering a postback to the server, which takes a while to complete before running the script. Is this correct behavior?

Thanks,

Mats

Mats,

Yes, that's the behavior by design since the XForms engine's intelligence is on the server. How long exactly it takes depends on factors such as server performance and network latency.

Re: Re: newbe question reg. orbeon xforms engine

Erik,

Ok thanks for the explanation. In my case it seems the responsiveness of my forms when served by orbeon is not satisfactory. The orbeon forms engine seems to offer a number of neat features, however, good responsiveness is a critical factor for me. So I may have to stick with a client side xforms engine, while using orbeon for the page flow control etc.

Are there any initiatives to incorporate a pure client-side xforms engine with the orbeon framework?

None that we are aware of at this point. Which did you have in mind?

Re: Re: Re: Re: newbe question reg. orbeon xforms engine

Formfaces is one example which I think comes a long way.

Btw, one issue I see with client side implementations is how they can interact with orbeon's page flow control. In particular I'm trying to figure out how xforms submissions with replace="all" can be achieved. Any ideas?

Thanks,

Mats
