partial lists

Hi,

I just started using displaytag and this mailing list.  I'm getting a massive headache trying to get External paging/sorting working.  It seems to make sense in the documentation, but I'm getting the following error from my jsp page:

Caused by: javax.servlet.jsp.JspTagException: You must specify one of the following: size
        at org.displaytag.tags.TableTag.initParameters(TableTag.java:966)
        at org.displaytag.tags.TableTag.doStartTag(TableTag.java:722)
        at org.apache.jsp.WEB_002dINF.jsp.txsearch_jsp._jspService(txsearch_jsp.java:620)


I am specifying that parameter, but it doesn't seem to recognize it.  (This was working fine before I tried to use external paging with partial lists) Here is my table tag on the offending line of jsp code:

 <display:table name="results.list" id="txResults" sort="external" defaultsort="1" export="true" pagesize="5" requestURI="" partialList="true" size="7">


I've tried many different things including different expressions for size, and as in this example, just hard coding the correct value also changing the order of the attributes.

I've also looked at the source code and the mailing list archives without solving the problem.  This dead thread seems to show the same unresolved issue:

http://www.mail-archive.com/displaytag-user@.../msg05950.html

The author of that thread gave up :-(  to implement it themselves.


The line of code in the displaytag source where it is failing is org.displaytag.tags.TableTag.initParameters(TableTag.java:966)

I've copied that line and the surrounding code below but I can't figure out anything from it.

Please help me or I fear I will suffer the same fate as the previous poster and have to abandon use of displaytag entirely.

Take a look at the documentation:  http://displaytag.sourceforge.net/11/tut_externalSortAndPage.html

 

I believe that when implementing in this fashion that the size parameter must be set to the name of variable that is a java.lang.Integer that is in a scope accessible by Displaytag.

Thanks for the feedback, i suspected this as well but I've been unable to get it working.  I tried it in several ways, first by adding an Integer to my Spring MVC model.  That got the same exception, then i tried to make it as simple as possible with the following JSP code:

<%
    Integer listCount = new Integer(7);
%>

<display:table name="results.list" id="txResults" sort="external" defaultsort="1" export="true" pagesize="5" requestURI="" partialList="true" size="listCount">

...

(I also tried with size="${listCount}")

This still generated the same exception.

Does anyone have a working example of partialLists implemented anywhere?  I can't find a war file example, the displaytag example are lacking this recent feature.

Hi,

I had the same problem today. After 1 hour wasted, I discovered that the object that display:table is passed as "the number of items in the current page" must be of type Integer. In my case, the exception appeared because the type of the object was string. Here is my work-around:

// Struts form property accessed from JSP
// This doesn't work, returns String instead of Integer
public String getNumItems() {
     return numItems;
}

// Struts form property accessed from JSP
// This wrapper will work just fine
public Integer getNumItemsAsInteger() {
    if (StringUtils.isBlank(getNumItems()))
    return new Integer(0);
    return Integer.parseInt(getNumItems());
}

Good luck to you all :-)
