How to Invoke a function written in a Bsh script through FTL.

[vijay Si]

Hello friends,

I wanted to invoke a method (with parameters) from an ftl file .

The method needs to be written in a script file (to separate out
presentation from business logic).

I have read the ftl manual but it does not have an example of passing
arguments to a method which is defined in other script file.

What are the possible ways to do this?

Regards

Why not just run the bsh script before the ftl like we do everywhere in
OFBiz?

Regards
Scott

Hi Scott,
 I will explain the problem in  detail.
I have a function fnRT(int x1,int x2...........,float xc1,...)
The values of x1, x2 ..... will vary scince i will invoke fnRT() MORE Than
once with different parameter values.

I wanted that each time a fnRt() is invoked in FTL,    The method

gets invoked in BSH Script which does a necessary calculations and passes
out the results as a list to FTL.
FTL can then use the results for display.

My problem is to handle the runtime parameter passing bsh script and then
retrieving it in ftl...............If i run the bsh script before the
ftl.........then how am i supposed to get the function parameters in
advance...

Regards

Hi Vijay

Everything that is available to the ftl is available to a bsh script running
beforehand, you just need to prepare all your data first then use the ftl to
lay it out.

Other sugestion, call the method from .ftl:
i.e:
in .ftl file:

<#assign result = Static["package.ClassName"].yourMethod( par1,par2....) >

I suppose that could work if you can find a way of executing the bsh through
a static call, but for anything other than simple data calls like
getNameForParty (i think it's called) it's really not the best way to go.
