How can I prevent query executing on loading page with POJO dc

Question

I created with POJO datacontrol with a method return a list of data. I created a taskflow with a page fragment to add the POJO function as a form. I found the method is called every time when the page is being loaded. How can I control it not to be invoked at loading time. Only invoked when I click the button binding to the method. Thanks.

Hi,
I created with POJO datacontrol with a method return a list of data. I created a taskflow with a page fragment to add the POJO function as a form. I found the method is called every time when the page is being >loaded. How can I control it not to be invoked at loading time. Only invoked when I click the button binding to the method. Thanks.remove the pojo function added as a form from pageDef file (you can do it manually by rightclick on page -> page defination.
then click '+' icon on Bindings section -> on insert item dialog box select method binding.
then select your pojo data control and select the method that you want to add (if it has parameters then leave it blank for now.)
for executing operation binding(method call) create a button action action listener and add following code
BindingContext bindingContext = BindingContext.getCurrent();
BindingContainer bindings = bindingContext.getCurrentBindingsEntry();
OperationBinding operationBinding = bindings.getOperationBinding("method name");
operationBinding.getParamsMap().put("param-name", "param-value"); //incase if method has parameters
// Invoke the method
operationBinding.execute();Regards,
