Dynamical change read only property of columns based on a profile option

Question

Hi,
We are attempting to change a Oracle iProcurement(ShoppingCartPG) which has certain readonly columns by default.
However, we need to make these columns updateable based on a responsibility level profile option. The code goes something like this.
if readonly_profile_option = "TRUE"
{make columnA property = readonly}
else if readonly_profile_option = "FALSE"
{make columnA property = updateable}
I read the guide about switchers and it seems confusing (to me). So if someone can provide an example with some pseudocode that will be helpful.
Also, can I dynamically add an LOV to column A if readonly is false? Of course the LOV should be disabled if readonly.
Thanks a lot

Hi,
Thanks for the feedback.
Tapash,
Switchers definitely don't make sense.
Raffy,
Didn't know it was that simple. I always thought that the controller fires--> then the page renders --> then the VO attributes get poulated. Basing my understanding on this flow, I though that the bean properties can only be set in controllers and not in VOs(via SPEL). I'll try it tomorrow.
Aprreciate your comments on the following.
Our requirement is to make an Oracle seeded field(SupplierName in iProcurement) updateable and with an LOV . Oracle has seeded it as ReadOnly.
I have two options.
1. If I change the readonly property in jedeveloper(I cannot access it via personalization) and add SPEL that would be upgrade 'unsafe' customizing - I think.
2. So I thought I'll extend the controller, substitute it and use
messageLOVInputText SupplierNameBean=webbean.findChildRecursive("SupplierName");
if{profle=not_read_only)
{SupplierNameBean.setReadOnly(false)};
else
{SupplierNameBean.setReadOnly(true)};
This is more upgrade safe. I have talked to the iProc development team and they are fine with it.
