I ‘ve recently created multiselect plugin for APEX 4.1 – there is still little information about how exactly write APEX plugins, and some aspects – like cascading LOV, I have not found explained anywhere, so I’d like to share my experiences here:
What You Need
To write plugin you will need:
- Oracle Database and APEX running somewhere – the installation manual for APEX is very good and you can go step by step according to it
- Knowledge of PL/SQL – it is good to have PL/SQL Reference at your hand
- Reference documentation for APEX 4.1 API
- Some knowledge of APEX and also some basic knowledge of plugins – try some available tutorials you can find on web – this article will focus on rather specific issues within Item plugin.
- Oracle SQL/Developer (or other development tool)- to write PL/SQL – optional, if you are PL/SQL god and can write correct code by heart – if you struggling with PL/SQL like me this is an invaluable helper.
