Dependent Dropdown

[ttran]

Hi,
Can someone point me to a example of how to do a dependent dropdown with datasource. I am using smartGWT Pro. I have tried mulptiple ways to try to get the second dropdown to filter base on the first but no luck.

Currently I have 2 DS.

1st is for Business Line
2nd is for Product Line

On the Product Line I tried adding a a whereClause in the DS like:

<whereClause><![CDATA[
status = 'A' and tbl = $criteria.tbl
]]>
</whereClause>

I set the autofech of the 2nd dropdown to false.

onchange of the first dropdown I got the key for tbl and passed it in as criteria and did a fetch. However, I am either getting a Oracle character error or I am getting a Umbrella exception from smartGWT.

I am sure there is a easier way to do this. If you have examle like State and City or something like that that would help.

Thanks,

I found an example in the demo. I will give it a try.
