For my dataview I've creating a simple filter with expression builder.
<dmx-data-view id="data_viewBrokerages" filter="name.contains(modalMigrateAdvisors.brokerageFilter.value)" pagesize="20" page="1" dmx-bind:data="scGetAllBrokerage.data.queryGetAllBrokerage">
All good.
Now I want to enhance this filter a bit and I've added .lowercase() so that it wouldn't be case sensitive
<dmx-data-view id="data_viewBrokerages" filter="name.lowercase().contains(modalMigrateAdvisors.brokerageFilter.value.lowercase())" pagesize="20" page="1" dmx-bind:data="scGetAllBrokerage.data.queryGetAllBrokerage">
And now when I'm opening expression builder - error shows up and current expression is not displayed at all
Funniest part that this code works well.
