Where is displaytags getting its table from?
Here are a couple of pages that may help.

=> DisplayTag makes html / hrefs like

<th class="sortable">
<a href="CustSearch.action?d-49653-o=2&amp;dog=Hello+from+%27dog%27&amp;attr1=Hello+from+getAttr1&amp;d-49653-p=1&amp;cat=Hello+from+%27cat%27&amp;d-49653-s=2&amp;bttra=Hello+from+getBttra&amp;attra=Hello+from+getAttra">dayOfBirth</a></th>
<th class="sortable">
<a href="CustSearch.action?d-49653-o=2&amp;dog=Hello+from+%27dog%27&amp;attr1=Hello+from+getAttr1&amp;d-49653-p=1&amp;cat=Hello+from+%27cat%27&amp;d-49653-s=3&amp;bttra=Hello+from+getBttra&amp;attra=Hello+from+getAttra">address</a></th>
<th>postalCode</th>

How these "d-49653-.." parameters could be reaplaced to another syntax that OGNL accepts ?

I tried also with Servlet / Filter, but didn't managed to replace (haven't done much servlets ).

/Sakke

Hi,


DisplayTags (SourceForge) sends a HTTP / GET-method to retrive next page
data.

It uses a parameter like 'd-49653-o' to control request (for
application).

OGNL don't accept this syntax and throws an exception.

Solution is to make an interpreter before Action to convert this to
another syntax ?

// - - - - - - - - - - - - - - - - - - - - - - - - - - - -
