ADempiere problem involving BeanShell scripting

[DataSmith]

Hello

I'm struggling with BeanShell scripting in ADempiere.
Outside of some return statements and some strings, nothing really works the way it should.
I'm a Java/Objective-C programmer and even if I am used to Java, BeanShell is making me to pull my hairs out.
I read the scripting tutorial on the ADempiere Wiki page, but I don't understand how to use the prefixes, the ones with the W_'s, G_'s, A_'s and the rest of the A_'s: A_WindowNo, A_Tab, A_Field, A_Value, A_OldValue, A_Ctx.
I tried this to retrieve some data, but it doesn't work:

Code: Select all

return "Validation... Color: " + A_Tab.getValue("COLORNR");

where COLORNR is a column in my database. It doesn't find the A_Tab.
Could someone explain how to call a method and how to use the prefixes, because the documentation is very poor... unfortunately.

Thank you !

Hi DataSmith, I think it can work better if you describe your need and we can guide you through the process.

I'm using beanshell extensively for callouts and validations in one project and everything is working fine - just added complexity on debugging (so, the old method of System.out.println comes to help) and some strange quirks regarding beanshell (like scope of variable definitions).

Hi !

So the problem is that I have to filter out some input fields, for example the user must enter a number between let's say 10 and 20 and I don't know how to implement the conditions for this.

Thank you !

Carlos,
I will be interested to see some of your best sample 'hidden' script.

It would be very helpful if someone could help me resolve my problem.

Thanks !

No Redhuan, they're not hidden, they're just so full of references to custom tables and columns with spanish names that probably won't be too useful for standard Adempiere.

You don't need script for that. You can set MinValue and MaxValue on AD_Column.

Hello DataSmith,

I'm sure that Carlos' solutions will help you with your problem, if that is everything you need. But as you are doing a customization I also know you must understand how to extend ADempiere. like I told you before in the other post (http://kenai.com/projects/seterpadempiere/forums/soporte-funcional-adempiere/topics/523611-ADempiere-problem-involving-conditions- )

this link could be a good place to start. http://www.adempiere.com/index.php/Development
