setSearchOption bugged

Hello,
I'm trying to set a default date range for recors on a list page. I use the following code in "After table initialized" of the "news" table to get records of the last 5 days:


FIRST BUG:

$srchObj = SearchClause::getSearchObject("news_table")

$srchObj->setSearchOption("newsdate", BETWEEN);
$srchObj->setFieldValue("newsdate",date("Y-m-d",strtotime('-5 days')) );
$srchObj->setSecondFieldValue("newsdate",date("Y-m-d") );

I tried also with

$srchObj->setSearchOption("newsdate", MORE_THAN);

In both cases I get the search field formatted as an "equal" field and the code does not work.

SECOND BUG:
I use european dates (d/m/Y). If I pass the date in this format the first field of the between seacrh does not work, but the second does.
If I pass dates in the format Y-m-d as in the code above, the first field work but the second doesn't.


Does anybody have any workaround until the functionality will be fixed? Thanks!
