Experience in adding a custom tool for adding data to a custom master in example-simulated

OG-Platform

I have been trying to build a CustomTool extending AbstractTool to populate data to my custom master.

I made a CustomToolContext class extending the ToolContext for that…

@BeanDefinition
public class CustomToolContext extends ToolContext {
/**

  • The Custom master.
    */
    @PropertyDefinition
    private CustomMaster _customMaster;

…
…

and I have added a custom toolcontext part in the toolcontext-xxx.ini file in the config.

My aim was to access the custom master in the Custom tool created myself by the following code.

customToolContext.getCustomMaster();

Everyting seemed to be ok from the coding perspective but sucked with a class cast error.

tracking this class cast error I reached the code in ToolContextUtils.java

after a close watch I smelled something in the line 90’s in the function

public static ToolContext getToolContext(String configResourceLocation, Class<? extends ToolContext> toolContextClazz, List classifierChain)

…
ComponentManager manager = new ComponentManager(“toolcontext”);
manager.start(configResourceLocation);
ComponentRepository repo = manager.getRepository();
return repo.getInstance(ToolContext.class, “tool”);
…

I made a build to the OG-Component after changing the return statement to

 return repo.getInstance(toolContextClazz, "tool");

working fine for me in the particular case when we create custom tool context I believe.

so far I could not find any side effect for the change, though I am not sure this is the solution.
