'*' is not working in Select in field trigger in ajax

[#1]

Hi,

I have a list of product names like Horlicks, Boost, Bournvita, Complan.

I want to select all these values on clicking a button (am using text object) and written a trigger

Select in Field : Productname

Search String : *

This is not working in Ajax View, but it works fine in offline (Client).

The productnames differ based on other field selection so i cannot hardcode product names in the expression, so used '*'.

but it is not working in ajax. what might be the reason?

Since you want to select all values you don't need to select any value. Just make sure no values are selected. You can do this with a Clear Field action. In QV if no values are selected in a field QV acts as if all values are selected. An alternative is to use a Select Possible action instead of a Select in Field action. You could also try using ?* as search string.

Hi gysbert,

Even i have a selection for those product in listbox.

If i select a product in a listbox, then it should show that product in a chart.

I have a text object "Select All", Clicking this should select all products.

I tried ?*, it selects all values in a listbox (productname), but one more problem is that am using variable like this  vproductname = getfieldselections(productname).

I am using the above variable in a chart expression like

Sum({<product_name = {$(vproductname)}>} Volume)

so here it is passing ?* as a value for the product_name, so the chart shows "No data to display"
