[Lift] Re: What is purpose of RequestVar/StatefulSnipplet for forms?
What do you mean these functions are called only on submit? Is that when the POST goes through and the page is rendered again?

There must be something I'm missing here. The functions are called after form submission, and the variable desc and amount will be updated. However those variables will belong to the original method call. So when the page is re-rendered (e.g. because of validation errors), the add method will be called again, and fresh variables will be created. So the values won't be retained. If you want to keep the values between updating and re-rendering, you need something more global, like a RequestVar or a StatefulSnippet. -- Adam Warskihttp://www.warski.orghttp://www.softwaremill.eu -- You received this message because you are subscribed to the Google Groups Lift group.

[Lift] What is purpose of RequestVar/StatefulSnipplet for forms?
Hi,
I'm reading the lift book about forms, and in reference to this code:
def add (xhtml : NodeSeq) : NodeSeq = {
var desc =
var amount = 0
def processEntryAdd () { ... }
bind(entry, xhtml,
description - SHtml.text(desc, desc = _),
amount - SHtml.text(amount, amount = _),
submit - SHtml.submit(Add, processEntryAdd))
}
am coming across:
That means that if you want to retain values between submission and
re-rendering of the form, you’ll want to
use RequestVars (Section 3.16) or a StatefulSnippet (Section 3.11.2)
instead .
What's the purpose of RequestVars and StatefulSnippet? I thought the
values were retained anyway through POST. That is, on submit, the
functions desc = _ and amount = _ were executed and the so the
state was kept...
Are those functions only executed after the bind is complete? There
must be something I'm missing here.

[Lift] Sending a File back in custom dispatch
Hi, What's the preferred way of sending back a static file (that lives on the host filesystem) through lift? I'm using lift's custom dispatch. I'm currently putting a FileInputStream into StreamingResponse. I'm not setting a Content-Type in the StreamingResponse constructor, but Jetty seems to be sending: Content-Type: application/xhtml+xml; charset=utf-8 This is obviously bad for CSS files or images that I'm serving. Is there a smarter way to send the contents of files? Preferably one that automatically sets the correct Content-Type... or leaves it blank for the browser to ascertain. Of course, I can always use the Java mime-util library to detect and set for each file, just wondering if there's a smarter way to do this. -- You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Sending malformed HTML in custom dispatch
I'm using custom dispatch (to handle both XML media files). Often, I will want to send a page that contains user-inputted (X)HTML. This will often be malformed HTML that is nevertheless rendered fine by a modern browser. How would I send this through? I tried PlainTextResponse, but it sends the wrong mime type and shows up as well... plaintext. And XHtmlResponse requires valid XHTML. Is there any response that sends a String and claims that it's (x) html? -- You received this message because you are subscribed to the Google Groups Lift group.

How should the messages be displayed? AFAIK, per field message display

Yeah... I need to fix that. http://github.com/dpp/liftweb/issues#issue/254
You can display all errors (incl field errors) by
including the
lift:Msgs showAll=true/
snippet. Note the showAll attribute which is now needed to show field
level errors.

[Lift] Re: NPE when deploying WAR to Jetty
Thanks! Your posts pointed me in the right direction. Basically: this was a quirk of the distribution I was installing onto: Ubuntu 8.10. On 8.10, the two installed java distributions are openjdk and java-gcj- compat. Unfortunately, jetty does not know about openjdk, so defaults to java- gcj, and yields this error: ERROR - Failed to Boot java.lang.InternalError: One of the management beans is not compliant. at java.lang.management.ManagementFactory.getPlatformMBeanServer (libgcj.so.90) at org.apache.derby.impl.services.jmx.JMXManagementService$3.run (Unknown Source) at org.apache.derby.impl.services.jmx.JMXManagementService$3.run (Unknown Source) [...] Right, so editing /etc/default/jetty and setting JAVA_HOME=/usr/lib/ jvm/default-java made Jetty use OpenJDK instead, and now everything is just chipper. - for now.
