Hello experts, I have a requirement as below. I have a table in which i need 2 dependent poplists. First dependent poplist for Inventory Orgs, which will show all the inventory organizations based on Form Value OrgIdLine. In processRequest, i am binding this with the OrgIdLine as shown below: OAAdvancedTableBean table = (OAAdvancedTableBean)webBean.findChildRecursive("ItemSubinvsRN"); OAMessageChoiceBean orgCodeBean = (OAMessageChoiceBean) webBean.findIndexedChildRecursive("OrganizationCode"); orgCodeBean.setListVOBoundContainerColumn(0, /* bind index */ table,"OrgIdLine"); orgCodeBean.setPickListCacheEnabled(false); here is the query for this poplist. select organization_code ||' ('||organization_name||')' organization_name, organization_code,organization_id from org_organization_definitions ood where operating_unit = :1 order by organization_name This is working fine and giving me the Inventory Organizations based on OrgIdLine form value. Second poplist for Subinventories related to the Inventory Org selected in the first poplist, In processRequest, i am binding this with the Inventory organization selected for the first poplist as shown below: OAMessageChoiceBean subInvBean = (OAMessageChoiceBean) webBean.findIndexedChildRecursive("Subinventory"); subInvBean.setListVOBoundContainerColumn(0, /* bind index */ table,"OrganizationCode"); subInvBean.setPickListCacheEnabled(false); This poplist is not showing any values after selecting the Inventory Organization. here is the query for this poplist. select si.secondary_inventory_name sub_inv, si.organization_id from mtl_secondary_inventories si, org_organization_definitions ood where ood.organization_code ||' ('||ood.organization_name||')' = :1 and ood.organization_id = si.organization_id and nvl(si.disable_date,sysdate+1) > sysdate Can any one help on how to get the Subinventories (depending on first poplist Inv Org) related to Inventory Organization (depending on form value OrgId) inside table region. Thanks, Sree.
