Uitable Error with GUI

Matlab-Version: 7.12(64 bit) Java-Version: Java 1.6.0_17-b04

When I run a uitable out of a graphical user interface the following error message occurs:

com.mathworks.jmi.MatlabException: No constructor 'com.mathworks.mlwidgets.array.ValueMetaInfo' with matching signature found. at com.mathworks.jmi.NativeMatlab.SendMatlabMessage(Native Method) at com.mathworks.jmi.NativeMatlab.sendMatlabMessage(NativeMatlab.java:210) at com.mathworks.jmi.MatlabLooper.sendMatlabMessage(MatlabLooper.java:121) at com.mathworks.jmi.Matlab.mtFeval(Matlab.java:1550) at com.mathworks.hg.peer.ui.table.

Then the table is completely drawing but without data values.

With Matlab-Version 7.6 the same program works without problems.

If I create a uitable with the same parameters (the only difference is the Parent property) using the command line then it works also in the new version.

I hope someone can help me here or has an similar problem.

I've got same problem, and I found the solution.

previous 'uitable' is not working at MATLAM 2011 anymore. Instead, they provide java-type uitable :

t = uitable(rand(3),{'A','B','C'})

the handle t is not usual MATLAB handle. It's JAVA component. you can operate it by using 'methods':

 t.methods

example :

 t.getData

 t.setData(num2cell(rand(3)))

 t.setPosition([100,100,200,300])

Good Luck! :)

Many thanks for your efforts.

Showing results works with this proposal. But to define a parent-handle for this uitable object is not possible....

With methodsview('javahandle_withcallbacks.com.mathworks.hg.peer.UitablePeer') all methods from uitable object can be seen.

And so it is not possible to integrate the new uitable format in a multi window GUI.

How about this? :)

f1 = figure;

f2 = figure;

set(0,'CurrentFigure',f1)

t1 = uitable([1 2 3],{'A','B','C'})

set(0,'CurrentFigure',f2)

t2 = uitable([4 5 6],{'A','B','C'})

t1.setData(num2cell(rand(3)))
