Passing date types with jsFunction or commandLink

[gwzoller]

Hello,

I'm trying (unsuccessfully) to pass a date object back to the server side via jsFunction. I'm using a jQuery UI datepicker, but that shouldn't be relevant. When a date is selected the onSelect function is called, which calls my jsFunction code with (in this example) a fixed date. Code below:

 <a4j:jsFunction name="sendDate1">
 <a4j:actionparam name="date1" assignTo="#{dateMgr.date1}" />
 </a4j:jsFunction>
 <script class="javascript">
 var foo = jQuery.datepicker.parseDate("mm/dd/yy", "05/20/2009"); // create js date obj
 jQuery(".inlineDatePicker").datepicker({
 inline: true,
 onSelect: function(dateText) { sendDate1(foo); }
 });
 </script>

 <!-- Doesn't work either -->
 <a4j:commandLink value="Click Me!" ajaxSingle="true" action="#{dateMgr.setDate1(foo)}"/>


// Java Server-Side Code
 public void setDate1(Date date1) {
 this.date1 = date1;
 System.out.println("date1 set to "+date1);
 }

What happens is that the ajax call does fire but passes null in the post, and thereby setting the server-side bean parameter to null.

I've passed Strings like this before but I don't want to wimp out and convert all my server-side dates to strings if I can avoid it. I should be able to pass JS Dates, shouldn't I?

Any ideas how to do this right?
Thanks!
Greg

Hi Greg, have you tried something like this:

<a4j:commandLink id="ClickMe" value="Click Me!" action="#{dateMgr.setDate1}" reRender="WhatEverIShouldRerender" >
 <f:param name="date1" value="#{dateMgr.date1}" />
</a4j:commandLink>

Just give it a try....
