Column Setting of LiveVariable Changed without any intention

During the development of my wm app, the column setting of LiveVariable has been changed without any intention.

The attached file "saved.png" shows how I saved the setting.
Then it was saved correctly and worked for some time (a few hours, days)

However suddenly, I found that the setting is changed, like the attached file "changed without any intention.png".
This problem happens really often, for several LiveVariables.
Always, if this happens, the sub-colomns (with relationship) are changed to be unchecked.

I'm not sure what causes this trouble. Please help me.

Export CSV with selectedRow on dojoGrid

Hi everyone,

I want to export, in a csv, a selection when I made.
So I have 2 grids :

Grid1 = all my data

I use this.dojoGrid1.setQuery(row : "myRow");

But the result of this query doesn't appaer (I got empty grid). I have to quit the layer, then come back at the layer to see my query. May be the issue is the dojogrid is not update.. but how can I update it in JavaScript?

After, I want to select automatically all row(s). But that doesn't work..

Need developer to continue work started

We have an application that needs some debugging and many more enhancements. I am looking for a developer that wants to develop a long term relationship working on our project from time-to-time. Jakob Perz was the last to work on the project and he is VERY GOOD, but it seems he is very busy and our project is not so big that he gives us the time we need.

Last time I posted I received many good inquiries, but I have since deleted them, so please resend me email if you are interested.

Email me at and I will send over details.

Get data from SelectMenu


I don't manage to get the value from my SelectMenu.
In fact, my SelectMenu allow people to choose a line in the drop-down list or to write the answer.
If this person choose an answer in the list, it's OK, but if the person write the answer, I can't to get the value. And I don't understand why..

In my code (JavaScript):
console.log("Answer = " + this.myDropDownList.getValue("dataValue").c0);

In my debug:

If the person choose an answer in the list > "Answer = Anwer1"

If the person write an answer > TypeError: Cannot read property 'c0' of null

MySQL Tables Not Updating After First Run

I am completely stumped on this one.

I created the simplest version of my application: two tables related in many to one fashion. The second table is used as a lookup for a value in the first table.

The problem: After the first time I run the application, I cannot update the tables any more.

I have tried two versions of Wavemaker: 6.5.3 and 6.6.0.M3. I've updated to the latest CE version of MySQL - 6.0.
