Circular dependencies in IDempiere

[chen_xueqian]

Hi,
I want to put user defined models (such as I_Xx, X_Xx, MXx) into a new user bundle, such as “org.compiere.model.user”, separated from the original “org.adempiere.base" bundle and "org.compiere.model”. The result is, “org.adempiere.base” and “org.compiere.model.user” should dependent each other. So it caused circular dependencies, Eclipse cannot build. What would you suggest to handle this situation in IDempiere environment.

Thanks

Hello Xueqian,

Try to use 'Fragment-Host' to inject your class into base bundle. It is not good idea I think, but it should be working.

The proper way as I know is to use Extension-Point.

You need to implement your own ModelFactory for your model bundle.

I am not 100% sure for this. Waiting for a real working example.

Just my 0.02$,

1. Open Eclipse
2.Create a new osgi framework bundle something like ‘org.adempiere.model.user’,then creat a package named ‘org.compiere.model’,the package name must be the same as the Original model package.
3.Add dependency 'org.adempiere.base' in your bundle.
4．Put your user defined models(I_Xxxx,X_Xxxx,MXxxx) into package ‘org.compiere.model’ of your bundle,like ‘org.adempiere.model.user’ .
5.Navigate to Run > Run Configurations > Eclipse Application >Plug-ins,tick your bundle,and click run.

It's OK now.
