assigning $count to a jsp variable

Suppose there is
<bdm:display select="$COUNT"> ,
is it possible to assign the value of count to a jsp variable. Well I am not sure if it is possible and if yes how. This may be jsp-101, but i sure don’t know how to do it anybody ?

Hello,

we checked your problem, but we did not find a solution for it. It seams to be a non-trivial task.

Could be the use of the $SIZE variable an acceptable workaround for you?

In contrast to the $COUNT, the use of $SIZE avoids the repetition of the query execution. It displays the last result of the count. More details about $SIZE can be found within documentation of X-Application:

Have a look at ?Jsp Tag Library Reference? -> ?display?.

Write a post if $COUNT does not fit your requirements and why you want to store the result of the count tag. Perhaps, we can find a better solution for your problem.

Bye,
Christian.

Thanks for your prompt reply,

Infact size would be better than count for my purposes.
The motive is to keep a track of number of results of query and the number of results that are on the current page. That is why i require that the $COUNT/$SIZE variable to assigned to a jsp variable

<% int num = $COUNT %>
BTW is there some way to find out number of results on the page ?
thanks

Hello,

ok, new use case. Currently, we don’t have a tag or option for the count tag which returns the number of documents a browse list displays for the current page.

Workaround: you could create a dummy browse which iterates the documents. Within the body you increase a counter.

<% int docCounter = 0 %>
<bdm:browse … copy the attributes …>
<% docCounter++; %>
</bdm:browse>

If you don’t need the number before displaying the document list you can copy the counter into your existing browse tag.

Bye,
Christian.
