java - Tapestry 5 - How can I do client-side 'required' validation on <t:radiogroup>? -


i need validate, on client, whether 1 of radio buttons in <t:radiogroup> has been selected on form submission.

using standard t:validate="required" attribute not work

<t:radiogroup t:id="options" value="data.options" t:validate="required" >     <t:label for="option1"/><t:radio t:id="option1" t:value="option1"/>     <t:label for="option2"/><t:radio t:id="option2" t:value="option2"/> </t:radiogroup>

n.b. is possible server-side using standard validate="required" attribute - again need client-side.

it seems odd standard server-side required validation works standard client-side required validation doesn't work <t:radiogroup> component.

how else can achieve on client-side?

currently, have implement yourself. if there not issue this, should feel free add 1 tapestry's jira.

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
