setting NULL in AjaxRequest Parameter

Hi Techies,

I am using java external to fetch data via LSCS query on certain extended atrribute of DCR and

I need to pass blank string or NULL from Ajax Request to JAVA external at certain condition but in java external it is giving values > 0.

JAVASCRIPT CODE for AJAX CALL

var categoryParam = "category";
var categoryParamValue = "";

var request = new AjaxRequest(url, handleDocument);
request.setParameter(categoryParam, categoryParamValue);

request.submit();

In log I am getting value of context.getParameterString("category").toString().length() > 0 because of which I am unable to pass blank value to category extended attribute.

Am I doing something wrong?

What's the value of that parameter if the length is non-zero?

In LSCS, to query for empty string or null you should use "attributeName:~"

Hi,

I forgot to add, there is datum of singleselect which pulls the options from xml file using generator and this datum was used to pull data from external on page load and then using AJAX request to same class we are pulling subsequent data through paging on UI.

And this categoryParam variable is somehow pulling selected value of the above datum and passing to java class.

I didnt had time to figure out the real problem so for time being I changed the approach and updated the xml to pass the NULL using <option> tag of single select. And this solved the problem.
