GUI composer not able to read value of pointer

Other Parts Discussed in Thread: TMS320C28346

I am experiencing a problem where I cannot read the value of a pointer and display it in a textbox.

Following the example given here http://processors.wiki.ti.com/index.php/GUI_Composer/Bind_Expressions I am not able to display anything.

I tried both using array variables of an object, global array variable or simple int* variable. The result was the same: nothing gets displayed in the textBox. This is the related content of app.json:

"serverBindName": "evaluate['*(ObjectInstance.UDC[0])']", // As done in CCS Debug view (shows the correct value)

or

"serverBindName": "evaluate['*UDCvalueptr[0]']",

or

"serverBindName": "evaluate['*UDCvalueptr_moduleA']",

For reference the following works correctly:

"serverBindName": "ObjectInstance.VariableNotPointer[0]",

I'm using GUI composer runtime 5.5.0.2 runtime with Code Composer Studio  5.5.0.00077. Target is TMS320C28346 using JTAG Spectrum Digital XDS510 USB.

Since this project is managed in a team upgrading to CCS v6/v6.1 is not an option unfortutanely.

Any help would be greatly appreciated. Thank you in advance to all of you!
