Adding dynamic attribute to TangoTest and Restart device

Development C++
1

Hello,

I’m using VS2013 with tango 9.2.2

The test steps are;

  1. Using Pogo, add one dynamic attribute to TangoTest
  2. Rebuild and run (using Server_static project)
  3. At jive, create new device using server wizard
  4. Confirm that the new dynamic attribute exists
  5. Right click the device and “Restart device”
  6. Then the sever program clashs

The clash point is at TangoTestClass::erase_dynamic_attributes()

The call stack at the crash is

The newly added code by pogo is just belows with one additional file (TangoTestDynAttrUtils.cpp - refer to attached file)

at TangoTest.h

//	Dynamic attribute methods
public:

	/**
	 *	Attribute low_double_scalar_rw related methods
	 *	Description: 
	 *
	 *	Data type:	Tango::DevDouble
	 *	Attr type:	Scalar
	 */
	virtual void read_low_double_scalar_rw(Tango::Attribute &attr);
	virtual void write_low_double_scalar_rw(Tango::WAttribute &attr);
	virtual bool is_low_double_scalar_rw_allowed(Tango::AttReqType type);
	void add_low_double_scalar_rw_dynamic_attribute(string attname);
	void remove_low_double_scalar_rw_dynamic_attribute(string attname);
	Tango::DevDouble *get_low_double_scalar_rw_data_ptr(string &name);
	map<string,Tango::DevDouble>	   low_double_scalar_rw_data;

At TangoTest.cpp


void TangoTest::add_dynamic_attributes()
{
	//	Example to add dynamic attribute:
	//	Copy inside the following protected area to create instance(s) at startup.
	//	add_low_double_scalar_rw_dynamic_attribute("Mylow_double_scalar_rwAttribute");
	
	/*----- PROTECTED REGION ID(TangoTest::add_dynamic_attributes) ENABLED START -----*/
	
	//	Add your own code to create and add dynamic attributes if any
	add_low_double_scalar_rw_dynamic_attribute("Mylow_double_scalar_rwAttribute");

	/*----- PROTECTED REGION END -----*/	//	TangoTest::add_dynamic_attributes
}

Any idea why?
